Not much to say, 3950X is a genuine beast for productivity, gaming, engineering, statistical simulation, programming…etc.
Possibly cheapest price ever? You have to add it to cart first to get a 10% discount, then you get a further $50 off with PMONTH200.

damn that would have been tempting if i had not just got a 3900X
If you got the 3900X for $669.10 from these guys, then you got 75% of the performance for about 62% of the cost.
Unless you're running something that will hammer 16 cores for a significant amount of time, the only thing you missed out on is increased e-peen size.
Not that e-peen size is a bad thing, of course.

I got a 3970X. Told my wife that I needed it for work. Really just for the e-peen.
Useless for you because porn watching and facebook only need's a $100 cpu.
then you got 75% of the performance for about 62% of the cost.
You can use this argument all the way down to a $100 cpu..
I can get 10% of the performance at 8% of the cost buying a i56600…
That's true, but the gap between the two percentages is the important part as it usually increases (in the wrong direction) past ~the mid range or upper mid range. Anything lower than that will no longer meet minimum performance requirements and so isn't relevant in the comparison. I would call the 3600/3600X the bare minimum required for performance comparison.
If we pretend all relevant workloads are well-threaded:
A 3600/3600X for a theoretical $300 would be ~50% performance of a 3900X for 45% of the cost (a small gap of 5% between the two percentages (~10% relative))
A 3900X for $669 is ~75% performance of a 3950X for ~62% cost (a widened gap of 13% between the two percentages, i.e. more performance per dollar than a $300 3600/3600X (~17% relative))
The 3900X at that price is an outstanding deal for those looking for a workstation-esque CPU in this performance category, and given total system cost the 3950X is still good as well at $1083.
Its actually closer to 80-90% of performance and you are forgetting that you still need to buy a good cooler for it and the reality is even then it is only in very specific workloads that it shows a meaningful advantage. Most people will not see a difference between the 2 performance wise. However if you have heavy multi threaded workloads and don't mind dishing out a lot extra for cooling then this is a beastie.
I think at this price-point its not really aimed at "most-people". With 16 cores on hand you're probably doing more than one thing at a time on it.
How are you getting 1083? .. I'm only seeing it as $1209 (with the code).

Gotcha.. cheers!
Nice find!
I was one of those cynics that predicted against the rumors that AMD would do a 16C/32T CPU as a non Threadripper, in this generation… Gosh AMD are smashing it right now :)
Yeah, the competition is a good thing. I'm still running Sandy bridge and look forward to huge upgrade.
this thing costs nearly as much as my pc
3900X for $669.10 using the same method: https://www.ebay.com.au/itm/AMD-Ryzen-9-3900X-CPU-12-Core-24…
Yeah there's a premium on getting those extra 4 cores. I would just stick to the 12 core 24 threads and put the extra cash towards storage or GPU… That's just me and my desires though.
But don't you understand? That's 4 more chrome browser tabs you can open that can be bleeding you dry with electrical bills.
What are people using to cool this beast? Seems to have the same TDP as the 3900X yet no cooler included?
The 3950X is actually really easy to cool surprisingly. I'd recommend a Noctua NH-U14S or an NH-D15 (though this is quite big). Any 240mm AIO should also be perfectly fine.
I'm using the Dark Rock Pro 4, does a great job.
Want to buy another 3950X but can't find a decent motherboard in stock anywhere to go with it.
I think someone asked the same question this morning. Decent board, yes. Decent deal, sadly no. A very good x570 board for the price is the MSI Tomahawk
Howcome AMD recommend watercooling?
https://www.amd.com/en/processors/3950x-thermal-solutions
Never been a fan of W/C due to inherit risk etc
Do W/C setups often fail? Or is it just that when they do, the damage to the PC is catastrophic?
@Duckman: Not sure about custom W/C, but with AIO there's always the risk of leaking. It's not that often, but once it does, there's a high chance the whole PC will be goner. If you go AIO, best go with quality brand or those with warranty for the whole PC.
@Duckman: No, extremely rare. I've been custom watercooling for years. Never had any problems. AIOs are extremely popular so I don't think you have any reason to worry about it. If you are, just go with an air cooler and you'll be fine.
@Duckman: I have been wc'ing my GPU/CPU for 10 yrs now using deminiralised water with silver kill coil. I suggest keeping your wc loop design simple for longevity and maintenance.
@HugoBoss: I have been custom watercooling for years. The OEM for most of the AIO watercoolers is Asetek. Companies such as Corsair use them. Some had issues, but it's rare vs the amount of units out there. 3950x can be cooled well on air so go with what your are comfortable with.
This chip is really well binned and it's performance per watt is a step above pretty much every other chip in existence right now.
There are literally laptops with this chip in them and they run fine.
A dinky air cooler like the CM hyper 212 could probably run this fine.
Set it to eco mode and you could run this on the 3300X stock cooler because it'd actually use less power than the 3300X while keeping performance above the 3900X.
No one would recommend a dinky air cooler because if you're spending $1k+ on it you might as well not cheap out on the cooler
A high end air cooler like the dark rock 4 pro or a 240mm AIO would suit it.
@[Deactivated]: You probably could get by on an aircooler but I'd say the processor would just employ thermal throttling and clock itself down so you achieve lower performance than if it was water.
BTW looks like prices have darted up $200 or so since today.
@BargainKen: Nah, the 3950X won't really thermal throttle with a decent air cooler
If it can handle the 3900X it can handle the 3950X. The 3950X with full load uses about the same as a 3900X. With heavy but not full load it can use more power than the 3900X because higher power targets, but really out of the box a 3950x is capped at 142W max.
A basic air cooler like the 212 Evo is rated for 180W and a high end one like the dark rock pro 4 is 250W for what that's worth.
Even a tiny but good cooler like the Noctua NH-D9L can run it at full performance more or less, but anything lower and you will compromise on performance before of thermal throttling.
That said Ryzen is really efficient at lower voltages, automatically adjusts it's power targets and clocks with temp so even with a dinky cooler that can only handle 105W you'd still get like 95-97% of the performance vs a water cooler. It'd just be very loud (which could offset by getting a lower power target at the expense of some more performance, or undervolting)
TLDR: don't worry and don't overthink it, 3950x is surprisingly easy to cool.
well once you buy one, you can now do the helicopter with your now larger e-peen for all your cooling needs.
i use a NZXT Kraken Z73 360mm with my 3950x and it's absolutely dead stable, never a single crash. Great temps.
would this let me run lots of virtual machines or android emulators? with 32gb ram. and how many would it run at decent resolution and frames per second? i am hoping for 8 at great quality or 16 with tiny resolution but high frame rate (probably 480 x 270 resolution 30 fps)
but…..why?
because i don't want to buy in-game currency in my favourite online game. so i cheat. because they cheated me before i started to cheat. so i found cheats because they got me mad. now i build accounts with lots of currency and give them to others for free as well as for me. they don't know i cheat they just think im good at the game. i literally wanted to fly to korea and kick their ass
i spent around $700 on the game and i was doing too well for their liking so they reset my account, i assume, they didn't give me a reason.
ummmm
what game was that? I'm really interested
@bargaingod123: judging by the downvotes that would not be smart saying what game it is. i guess they support game companies that scam people.
@bargaingod123: you would have to be really dumb to tell someone what game they cheat on, especially a random person
which one better ?
for $1332.00
you get
AMD Ryzen 9 3900X, Gigabyte GA-X570 Aorus Elite WiFi Motherboard, Corsair Vengeance LPX CMK16GX4M2B3200C16 16GB (2x8GB) 3200MHz DDR4
https://www.scorptec.com.au/bundle/CPU/AMD-Socket-AM4/665-39…
See above you can get the 3900x for about $690. The other stuff is definitely not worth $600
The bundle isn't really good value
So ~1k2 or less if you shop around.
Having never built a computer, how do I find what this is recommended to be installed with?
I'm looking to build a portable workstation with this processor.
Thankyou
When you say portable workstation, do you mean small form factor that you can put in a backpack? What's your budget? I'll try and suggest a parts list.
You could start with the motherboard. If you are looking for a portable build than have a look at the following motherboards.
Gigabyte X570I AORUS Pro WIFI
ASUS ROG Strix X570I
They are ITX size and will fit in a SFF case.
Note if you require memory, you will be restricted to two RAM slots. So if you want 32GB or more, you will need at least two 16GB sticks of RAM.
I was going to buy 3950x for 3D rendering but all the 3D rendering moved to GPU now So I thought to myself I might save that money and put it towards GPU upgrade instead.
3950x would still be handy if you do any physics simulations like fluid, cloth etc. Waiting for physics calculations to ‘bake’ gets annoying.
3900x is a better value all-rounder at its current price. Like you said, you can put some of that money saved to a better or second GPU for render tasks.
Physics calculations and compiling video too.
I hope 4000 series makes a great improvement so I can upgrade to that years later.
