Hi all, long time no post. We got another big batch RX 6800. Unfortunately no RX 6800 XT this time. Probably one of the best price to performance cards at the moment. 12 months warranty as before.
Cheers,
Jun

I won't touch an AMD card, but if I were buying one, this would be a positive vs some crusty PC case with temperature fluctuations
I won't touch an AMD card?? … why not
I've been using AMD cards from 1998 when they were still ATi and have never had any big issues that would make me think they are more or less problematic then Nvidia.. who i've also purchased many cards from.
In fact over the past 25 years I've had more issues with Nvidia Cards :)
lol, didn't mean to come across as an AMD hater or anything but re-reading it looks that way.
I won't touch an AMD card?? … why not
Because I'm using Cuda, and I use opengl software.
I did suffer a lot with AMD's poor Opengl drivers with Polaris and Vega cards (even the linux drivers, which are much better), running tools by their driver developers as requested to gather logs, etc. AMD (and intel) just aren't there with driver software.
Nothing against AMD if you're doing windows gaming.
@idonotknowwhy: Yep. I love AMD cards for purely gaming. I put them in my kids PC's, but as a content creator, NVenc is far superior to AMD's encoder and why I don't use one myself.
@idonotknowwhy: FYI .. use opengl software has come a long with with AMD now.. even the PS3 Emulator has been fixed for almost every game.. so dont need Nvidia for that anymore.. Cuda.. yep.. cant avoid that one
though hardware unboxed use AMD cards for their workstation rigs including the video rendering machines because they hate all the issues they get with Nvidia and multi monitor support.. including wake from sleep issues..:) i guess some things Nvidia just doesnt care about
@vid_ghost: rpcs3 was actually okay on my Vega with Vulkan (just some graphics artifacts but it was stable).
though hardware unboxed use AMD cards for their workstation rigs including the video rendering machines because they hate all the issues they get with Nvidia
Yeah, I've seen opinions like this. Also people on Linux who prefer AMD because the drivers come with the kernel now. And it's cool how you can put linux on a hacked PS4 and it has hardware acceleration, etc.
I don't mind building the nvidia module every time I update the linux kernel, and I had more driver issues with AMD (twice, the introduced bugs in the Vega drivers which stopped me getting to the GUI).
Cuda.. yep.. cant avoid that one
Yeah… I'm kind of hoping Intel up their driver game, since their high vram cards are so cheap.
never had a single issue with AMD cards. maybe your pc cause isn't well cooled.
Try doing anything which uses Cuda cores on AMD and see how you go.
They aren't equal in features. Yes if you only do gaming (without new generation frame interpolation) then buying NVIDIA is paying for a heap of expensive silicon to sit idle. But if you use it in non gaming then AMD simply can't do the calculations.
@joelmuzz: I use a mac for video editing on apple silicon so nvidia can shove ther cuda up there arse
@kungfuman: Ok if that is your use case. But the exact same arguements apply for why Apple (especially laptops) have use cases over cheaper PC and are worth the premium if you have the use for those features.
@kungfuman: That's great, M1 Silicon is great for LLM inference as well (albeit slower than Cuda). Try fine-tuning on a data set and you'll be waiting for weeks though :(
Try doing anything which uses Cuda cores on AMD and see how you go.
+1 Cuda and OpenGL, even some niche vulkan apps like console emulators…
I'm sure AMD is fine for modern windows games, dx12, etc.
I bought a similar one of these ex-mining cards from this seller (6800, might have been a powercolor from memory - red dragon perhaps), and have been using it extensively for the last few months with no issues.
The card was in immaculate condition, original retail packaging/box. Completely dust free, fingerprint free, etc. Only sign of usage was from the screws on the bracket. Hasn't skipped a beat, sitting inside of a tight space/enclosure (Fractal Ridge).
oh man, not an XT model, I would've considered at this price if it's XT, even as mining card.
There needs to be a bigger discount on these cards.
~$420 and I'll bite, but $460 for an ex-mining 6800? Nah
Same.
For something that still has warranty it's a great deal, the only other gpus at this price point new are 7600s or 3060s (12gb) which are both far slower with less vram. Exmining cards take less brunt than a normal card does while gaming.
i tried mining on my card once and it maxed it out at 100%… The games i play do not do that and the power usage is low..if i want to see my card at max power usage i need to run furmark at 4-8k :) not sure what your talking about
@vid_ghost: There's not really much reason to not run a GPU at 100%, aside from heat and noise maybe. They can handle it easily.
@vid_ghost: Miners don't run their cards at 100%, they heavily undervolt and mostly use vram grunt. You make less money running at 100%. Using only 30-40% of your gpu's max power draw was pretty normal back then.
@joelmuzz: It's still better to undervolt since it lets you OC the memory higher compared to cranking the power to 100%.
Needs to be at least an XT for this price. Also being mined for 6 months isn't good. The memory is the weak part of any gpu and it's a myth mining cards are underclocked. The core is underclocked and the rest is overclocked then ran 24/7. Mining cards at least need water blocks on the memory chips to not be considered thrashed
It's not a myth, undervolting+underclocking core lets you overclock the memory more letting you earn more money (and saving money on electricity too). Optimally cards are run at 40-50% of their max power which is less than what gaming uses.
Being run 24/7 doesn't mean jack, pc hardware is designed to be able to run at full load 24/7, server cpus/gpus do this all the time years on end. This isn't 10-15 yrs ago, there's lots of protections in place to limit what you can do with your hardware these days even if I hate that since it has killed proper overclocking unless you do shunt modding.
2nd law of thermodynamics. More time = more heat.
Look up heat and longevity of electronics. It's not 10-15 years ago but electronics still don't run at 100% efficiency. PC components are still copper traces embedded in fibreglass. The only benefit of 24/7 you could argue is less hot/cold cycles. But sustained heat is far worse for components than temp cycling
Either way most cases the part should become obsolete before it breaks. But not all parts are made equal, especially thesedays. I'd definitely expect a sizable discount if it's a mining card. The gpu failure rate for even the most looked after cards is something like 2-5%. Frail pieces of shit they are
But sustained heat is far worse for components than temp cycling
Citation needed.
I'll take 24/7 sustained use over repeated temp cycling every time !
I reckon. These are ex mining cards. I.e. they are heavily used constantly. 6months mining = years of individual consumer use
Wouldn’t you expect a heavy discount for a card that’s probably reduced a significant portion of its life
Even a card that’s from a gamer used for years will probably see occasional use whereas these mining cards are 100% used continuously at max!
I.e. they are heavily used constantly. 6months mining = years of individual consumer use
Old wive's tale, mosts tests done show the complete opposite. Parts die from time, not from how heavy something is used. There's no difference between 2 gpus over the course of 6 months, one that was averaging 20% power and the other averaging 80% power. Only cpus degrade from extreme voltages since those are unlocked, amd/nvidia don't even allow increasing the voltage anymore on their gpus.
I got one of these from the last batch after sleeping on the xt cards and missing out. Couldn't be happier. Finally upgraded the 1080 without breaking the bank.
Playing cyberpunk Phantom liberty with some ray tracing at 60fps 2560 x 1080
Same, strong recommendation from me. Also playing Cyberpunk, in my case at 4k with most things on high/ultra. Absolutely loving it.
Card was immaculate when it arrived, zero problems.
I just wanted to let others know that the warranty is solid. I bought this card, but it wasn't performing well. So I had to return it. I guess I was a bit unlucky. Just make sure to save the box it comes in, so you can ship it back if necessary. The return postage was free as well.
Nice. Hopefully you can get 6700/XT in stock soon cos I'm in the market for one of those.
I want that xt model baby
fwiw the ex-mining 6800xt I bought from MetroCom in June has been running solidly with no issues. The price/performance from it is pretty damn unbeatable
How much was it?
Was $579 (minus whatever % from gift cards I had) from this deal - https://www.ozbargain.com.au/node/780604
Thanks
Same here. I even got some money back due to cosmetic damage from shipping.
It's been such an amazing upgrade. BG3 at 4K60
Hmm need some 10% off or better ebay gift cards to sweeten the deal
Wouldn’t a used 12GB RTX 3070 be about the same money and a better alternative?
There's no such thing as a 12GB 3070, but even if there was it would be significantly slower.
12GB RTX 3080 would be a better alternative, but those still seem to go for $800 used for some reason.
Interesting, the 3060 got 12GB which seems crazy so I just assumed later editions of 3070 would’ve been updated too…
Short version - memory bus size.
Long version - Memory size needs to match to bus width. It's one way they vary between the cards as it provides huge speed differences. The 3060 is 192 bit and the memory options are 6GB or 12GB, 3070 is 256 bit so it could be 8GB or 16GB, 3080 is 320 bit so 10GB. The 12GB 3080 is actually a just a slower 3080ti with a 384 bit bus. You'll notice 384 is double 192, thus why they have the same memory amount options. If they were to go outside this, they would either need to use non-standard density memory chips or put more memory chips on the cards making them large and more expensive. Making the bus size larger makes for a more complex and more expensive card too.
Same with the 3090, the 24GB is again double 12GB but still on a 384 bit bus.
They could have released a 6GB 3060 but likely due to DLSS and the machine learning stuff 12GB was a better option. Going to a smaller bus (128 bit) would have given them 8GB but a much slower card (namely the 3050).
@freefall101: Thanks for the detailed info.
I keep a 12GB 3060 in my NAS and it’s great for running stable diffusion etc locally.
Due to the memory bus the 3070 was limited to either 8gb or 16gb, but they had a 16gb RTX A4000 so they didnt want to compete with themselves lol
@Wicko: You can always DIY it! https://www.tomshardware.com/news/16gb-rtx-3070-mod
(note: No one should try this at home)
The only way they could have accomplished that would be by using 6 x 2GB VRAM modules and leaving 2 spaces unpopulated like the 4070, which would have reduced memory bandwidth substantially.
This would have made it slower than the 8gb card in most situations despite being more expensive to make, which would have made it a hard card to sell.
I've got an rx6800 and it replaced an 8gb 3070. The 6800 is better if you're not using all the fancy gizmos of Nvidia. But both are great.
It's not like the 6700xt which only runs 384gb's. It was annoying to see noobs recommend it over the 3070 due to the extra 4GB. In reality is was fast 8gb vs slow 12gb. Most games won't go past 8GB. 95% of the time you're just running slower speeds between the core and mem. And it's 192 bit
rx6800 however is 512gb/s and the 3070 is 448gb/s.
6800/6900 have superior mem architecture to nvidia. 6700, 6600 etc is far worse
I've really appreciated these cards. Got it used a few months ago and barely fits in my smaller case, had to even pull out some fans. But despite that, never run above 75 degress.
With a price like this, I can imagine this card will have the same staying power as the gtx 1080 and 1080ti.
Ohh tempting, make a decently priced upgrade for the GTX 970. Anyone wanna talk me down?
I undervolted my ASUS TUF 6800 to 0.940v and 2000Mhhz…lost around 10% performance but its only sipping 134w VS the 224w is was before :).. Nothing on the market can touch it at a 134w power using.. plus is has 16GBs of ram..
I guess thats why so many crypto miners purchases these cards
Nice. What did you use to undervolt it?
AMD Drivers
Go to - Performance / Tuning / Custom /
In GPU Tick Advanced control tick Enabled ( To change Voltage from % to a number ) and set the Voltage to 940 (mV)
Change the Max Frequency (Mhz) to 2000
Hit Apply in the top left.
And that's it your all done :)Super simple/stable and doesn't crash.
No need to touch fan tuning or power tuningAfter installing new drivers you may need to redo this. ( bit annoying but very simple to re-do ).
@EightImmortals: If you want to check power usage from before and after you can download FurMark to max out the GPU and check power usage with AMD Drives in Performance / Metrics
If you dont see GPU power usage listed you need to enable that in the tracking tab to the right side. ( Show/Hide ) options.. lets you customize what metrics to show.
If you want you leave the default Mhz at the 2150 the card will draw around 170w at 940mv :) at 2000Mhz it drops to 135w
There are videos on you tube that show how to undervult and overclock but i just wanted the lowest power draw
@vid_ghost: For further optimisation of power efficiency, it's also possible to use More Power Tool so that the minimum voltage at idle or slower clock is far lower, around 650mV if I recall.
@chyawala: my 6800 idles at 3-6w .. how much lower do i want it?.. my PC fans use more :)
With dual monitors at 165hz it idles at 30w
@vid_ghost: The clock fluctuates, so where your stock BIOS may go down to a minimum of like 880mV, MPT may achieve 1200MHz at just 650mV.
@chyawala: i got a better idle and total System power draw from switching to a new Corsair 2021 & 2022 (shift) RMX power supplies.. they have some of the lowest 20-80w low power draws numbers around.. Even lower then most platinum or titanium rated power supplies.
I think the Corsair SF850L is the king of low power draw at the moment.
Not talking you down from a 970 upgrade to a 6800 mate, just drop $460 on this weapon of a card and enjoy more raster power than a Bob Marley concert.
100% these are excellent for price to performance. I was after one of these around the 3070 launch and missed out, why I pulled the trigger on a 3070 deal. I would have preferred one of these for the extra ram.
I went from a 970 to one of the OP's 6700XT and I didn't regret it at all. Actually that's a lie, I'm now going to sell the 6700XT and get this.
bruh this is the same price as the previous batch almost a year ago?
What is bruh?
Disbelief bruh!
2nd hand prices haven't moved as new gen is terrible value + AUD FX has killed us
Gpu prices haven't moved at all in the last 2 years unfortunately. Radeon 6xxx cards+rtx30xx cards are pretty much have limited stock since they're not produced anymore and the newer gen gpus cost even more and basically never get discounted. From mining shortage to AI+shrinkflation.
unless you're desperate for a video card I would wait till 7000 series video cards drop.
RX7700XT in white looks so nice… even if its slower then this and only comes with 12GB's..
Almost bought one of these a couple of months ago to replace my 1080ti. Ended up finding a used (practically brand new) MSI 6800XT for a little over $600. I wasn't going to spend $900 for a 7800XT for basically the same performance or, even worse, a 4070. The fact that you have to fork out around $1k for a mid-range graphics card these days is ridiculous.
Nvidia is a greedy company. I always buy AMD for the value play.. never had any issues
It is stuffed up, once the used market is done with these cards there'll be no bargains left. I'm glad I got the 6800xt from a previous deal for 560ish, will last me this console generation. If intel/amd don't do anything significant by the time ps6 comes around we're all doomed, going to be paying 1k+ for a low tier card rebadged as a high tier card, we'll probably still be getting 'mid range' cards with 8gb vram.
Spare a thought for those of us that paid $2200 for a 6900XT during the crypto boom :)
Unfortunately buying them at those prices is what enabled these prices
It was always obvious prices would come down after crypto. But companies now believe people will pay anything if pressed. Boycotting is a thing of the past. If you want a new car you don't haggle, you're lucky and privileged enough to go on a waiting list. Fomoers destroyed what little power the consumer had. Companies can just build to order and keep demand strong/consumers desperate
Yeah well I made quite a bit on crypto so it felt like a free purchase anyway. So I went the other way instead of waiting, I jumped on the crypto bandwagon… made a lot then effectively bought it for free even at those inflated prices.
@4foxache: Fair enough. Unfortunately as a result, inflated prices have also carried over to the newer gens. ie If we want a 4080 we'll be paying those prices but with no crypto/roi
@MetroCom I'm looking for a 6700XT, any chance you can get us a deal on one of those?
I have one from MetroCom how much do you want it for ;)
Could someone explain the hesitancy around buying ex-mining cards? I haven't been keeping up with the space since the 10 series…
I've bought them before, and wouldn't recommened people buying them.
They're generally devices that have been run for x amount of time for @ high/continous load for mining. Miner will tell you that the fact the cards are run at high / continous load (vs normal gaming loads where temp. changes between idle windows usage & gaming) somehow extends their life, but it's all BS, and a way for them to justify their need to resell their old devices.
Fans would have a high degree of wear on them, similiarly with power delivery components.
Thermal interface material (GPU as well as thermals pads for power delivery & memory chips) would be worn out and need replacing. Replaing GPU TIM is generally simple enough for most capable individuals, but replacing power delivery / memory pad's is a more nuanced process (cost more to buy, and differing sizes are used in differing parts of the GPU. Get them wrong by .5mm and you're going to have all sorts of thermal issues).
GPU manufacturers never designed these cards with 'mining' in-mind so whilst using them for mining is ok and profitable for the miners, gamers should always be wary of buying them afterwards.
If you do buy one, then I suggest factoring in the cost of a set of suitable replacement fans, and look to all TIM (GPU compound as well as various pads), if you're intending to use it until it dies.
GPU electromigration on the ram and GPU can be an issue from running the thing 24/7 over 6-12months
Ram no longer is stable at the rated speed or the GPU is no longer stable at its rated clock speed…under clocking both can fix this but this can sometimes be a problem for mined on GPU's… i value stability over anything else when it comes to my PC parts. Its 100% a luck of the draw when it comes to anything second hand from any seller even if they say its not been mined on or has an easy life there is no way to prove any of that.
I would only buy one of these for $400 or less for the above reasons. That is my Value to risk price point… everyone has one they are happy with
In saying that a used $200 RX6600 /XT is the best because your not losing out on much and those lower end cards were not really mined on much if at all
GPU electromigration on the ram and GPU can be an issue from running the thing 24/7 over 6-12months
I hadn't heard of this. What would I notice as an end-user if this were happening to my card?
@idonotknowwhy: You would notice nothing at all…
99% of the time everything would work fine… the GPU and RAM headroom would be gone so overclocking wouldn't give you the best results.
Some very old GTX1080ti card that had a hard life need to be clocked a little lower to be stable but i dont think the 6800 is old enough.
CPU's can also get electromigration but 99% of CPU's would never be stressed 24/7 for a year+ like in GPU mining … at the end of the day its not really an issue… its just a chance it could happen.. but very unlikely that it would.. the fans failing or causing some noise are the most likely issue… also the Thermal past being very try needing to be replaced.. Idle temps should indicate if thats a thing.
I'm just blabbing about the 1% chance of something like this could happen haha :) ignore me
@vid_ghost: I've been reading up on this now, thanks. While looking this up, I also learned that some artifacts on an ex-mining Vega56 I had in the past, were probably due to damage to that HBM RAM it had (miners overclocked the memory on them).
I'm just blabbing about the 1% chance of something like this could happen haha :) ignore me
I like knowing about these 1% issues.
I once had an issue with a Dell laptop. Dell technician couldn't figured it out so replaced the entire motherboard, but the issues persisted.
It kept having crashes, input issues, etc. Eventually I noticed by chance, that if I loosen all the case screws a bit, the problems went away!
replacing power delivery / memory pad's is a more nuanced process
It has gotten noticeably easier in the last two years or so. Cheap and effective thermal putty are now easily acquirable (eg. CX H1300 13.5 W/m-K from Ebay or U6 Pro from Aliexpress). You'll no longer need to search up and down for the thermal pad thickness.
I guarantee you'll get a better thermal result than stock if you're willing to put in some effort.
I've had no problem buying & gaming on ex-mining cards. They've all come with warranty, which most 2nd hand cards don't, and which I've never had to make use of.
That said, even though I've never had to use the warranty, I wouldn't buy an ex-mining cards which didn't have it.
They're ran 24/7 with the memory overclocked. Increased heat around the memory modules.
Disingenuous people try to debunk this by saying "they're better looked after" because the core is underclocked. Memory is the most frail part of the card hence the hesitancy
Cards can last 20 years or 2 years. Obviously mining increases the chances it'll break and should be priced lower than used non mining cards.
Got one thanks OP! Wish it would have been the XT but this is still a good deal
Is it an upgrade to go from a 3070 to this 6800? I have a 3070 at the moment, but am quite concerned on the VRAM issue. Gaming @1440p atm and already a lot of newer titles make the 3070 struggle (TLoU, Plague Tale 2, etc.) just because of the VRAM.
Depends if you value ray tracing at all. For purely pushing frames, the 6800 will handle all you can throw at it in 1440p. With RT on, it'll barely break 30fps.
You can sell a 3070 for $400+… makes for a pretty cheap upgrade… and the 6800 is very future proof. uses the same amount of power and is a good bit faster
Here you go…. 6800 VS 3070 2023 Hardware unboxed review
16GB vs. 8GB VRAM: Radeon RX 6800 vs. GeForce RTX 3070, 2023 Revisit
https://www.youtube.com/watch?v=Rh7kFgHe21kIf you don't want to watch the video. I'll help..To sum it up (8GB is dead in new 2023 games and moving forward) sell the 8GB 3070 ASAP while there are still people gullible enough to buy it for $400+ dollars
This is also a good video showing the AMD's RX6800 using less power and pumping out more FPS using a RYZEN 7 7800X3D CPU :) "even if they are older games that dont really use 16GB's of ram."

For comparing GPUs I like use the Tomshardware tables

Good deal!
I purchased a used mining card from this seller and was very happy with it although it ran hot I thought that was just how 3070 Ti's were. After some time I started running into overheating issues and decided to try a repaste. The exisitng paste was all dried up and repaste dropped temps around 10 degrees.
This used RX6800 or cop the new RX7800XT? Will be using it for games at 1440p but struggling to choose between the savings or newer architecture
7800xt is twice the price of the 6800 on sale in this post. If I was looking at spending7800xt $$ I would throw in a little more to get a 4070ti .
