    Is this one of those great ryzen chips that gets recommended alot on OzB?

    • +20

      Yeah, the Ryzen 4000 series is great.

  • +3

    How would be the gaming performance in this?

    • +9

      It's OK from those reviews on YouTube, but at the end of the day it is still an integrated graphics, cannot compete with dedicated graphics.

      • +4

        For the noob here whats the difference between intergratrd and dedicated?

        • +12

          Dedicated means that you've got a separate chip (a GPU, or Graphical Processing Unit) providing the graphics. Integrated effectively means that the CPU does both the normal processing and the graphical processing.

          • +3

            @Jec: Thx

          • +7

            @Jec: Also, it should be noted that with integrated graphics, they heavily rely on the main memories speed. Hence if the memory speed of this laptop is high, the graphics performance should not be too bad.

            • -3

              @mushi33: Rubbish

              • +3

                @Jugganautx: Best explain the reason you say this rather than saying "Rubbish". I understand why you noted this but saying Rubbish doesn't help anyone.

            • @mushi33: Plus dedicated graphics has its own dedicated memory on board thus does not rely or take away from available system memory.

      • 4500U vega = GT 1030 = MX 150 ?

    • +1

      Not a gaming laptop. Dedicated GPU required for many / most games IMO.

      • It could probably play CS:GO decently.

        • +13

          It sure can. It can play GTA5 decently too.

          • @Joxer: Oh wow, that's really good.

        • +2

          correct me if I am wrong, but cs:go can be played decently on those Intel integrated graphics? source engine is well optimised. I play half life 2 on Intel HD 620 graphics 1080p hagh settings no problem

          • +1

            @shabaka: I have an it 8265U with Intel UHD 620 graphics, CS:GO gets 70fps on all low at 800x600, not great.

            • @Void: dual channel ram?

              • +1

                @shabaka: Single channel. Does it make a huge difference?

                • @Void: it does, any built in graphics be it intel or AMD benefit from dual channel setup.

                  I run Half Life 2 which shares engine with CS:GO on my backup laptop and I get 70+ fps on Shader/Texture/Detail all set to high on 1080p resolution. on battery power, too.

                  that's a machine running crappy i3-7130u with Intel HD 620 on board, with dual channel DDR4-2133 2x4GB

                • +1

                  @Void: This video shows side-by-side dual/single channel benchmark runs for Intel HD 620, which is close in spec to your chipset; in this case, dual channel gives 2x FPS.

                • @Void: Many reviews from Amazon USA claimed to have dual channel.

              • @shabaka: Integrated Intel GPU bottleneck.

                • @DisabledUser141524: Hmm maybe I should upgrade to 16GB then, it isn't my gaming PC though, do you think it'd still be worth it for general use with a bit of Photoshop?

                  • -1

                    @Void: No. Intel GPUs are weak. Dont bother.

                    When I used to do PS on my old laptop (6teh gen intel lappie with dual core), CPU is the bottleneck for PS, and integrated GPU (CPU) is the bottleneck for games on low setting.

                    • +1

                      @DisabledUser141524: Well I'm not exactly able to put a GPU in my laptop, and I have a proper gaming PC for that. I'm just wondering whether upgrading to dual channel will be worth it for a general purpose laptop that might do some light gaming.

                      • @Void: Not sure. Check what's the bottleneck. Usually it is the CPU.

                      • @Void: Apparently the difference between single and dual channel RAM is up to 30%.

                        • +1

                          @Ryven: I saw another source saying up to 50. Some RAM hogging games can even have their fps doubled. I think I might go dual channel some time in the near future then.

          • +1

            @shabaka: These are AMD chips with the substantially more powerful AMD Vega integrated graphics. Much much better than Shintel's IGPU.

      • -2

        The MX350 from nvidia is faster than the intergrated AMD GPU & its pretty thick and has a brick charger and not USB-C charger; nor does it have backlit keybaord and thats a must

        • What's the point of your post regarding the MX350 (which is trash)

      • Will it be able to play COD?

        • At low settings perhaps it'll run, but it won't be amazing. Think of it like an older low end GPU.

        • Yeah I run Warzone on mine. Runs OK if you cap FPS at 30. Needs low settings. Full HD works but I prefer 720p.

          Power settings need to be set to full, else it crashes.

          Check this demo: https://youtu.be/fhHaebZuslw

    • It's not too bad (I have the Ryzen 3500U with Vega 8) but if you need it for gaming, I'd recommend to keep looking for a dedicated GPU. There have been a few deals for about $100 more with a decent nVidia card.

      I play COD: Warzone, GTA V and Planet Coaster on mine. They run fine, but COD especially needed tweaking with the settings, and keep everything on low detail. Honestly for the money I paid for it, was just happy that they worked at all.

  • +15

    Such a nice piece of hardware. The only let down would be the weight of 1.65kgs

    • +44

      1.65kg is too heavy for you?
      Better start hitting the gym dude.

      • +47

        He meant too light

        • -3

          It's a laptop. Not a paperweight.

        • +2

          How is being light a negative thing for a laptop?!

      • +9

        Yeah look, you're right. I just tried to neg my own comment but it won't let me. The designers of OzBargain are too kind.

        • +8

          Well, you can still punish yourself by doing 100 reps of biceps curl with a 2kg dumbbell.

      • It's a 2-in-1 can be used as a tablet, not a laptop always stay on a desk.

        Touchscreen: 10-point Multi-touch
        Pen: Lenovo Digital Pen.

      • Lightweight baby!

      • -1

        Who the hell uses a laptop as a bench weight?

        I mean just because you can bench 100kg doesn't mean you'd want to wear underwear that weights 2KG + an extra 5KG around your penis all day right?

        • Unless you are a 5 year old kid, then you shouldn't have problem carrying 1.65kg around. Many others are over 2kg.

      • +2

        My laptop is ~1.2kg (Asus zenbook), and while I get that this comment is partially a joke, wouldn't a 33% increase in weight be pretty noticeable?

      • you should buy the Area52M then if u dont care about weigh

    • +8

      I completely agree. Really good model, just a touch too heavy - 1.4KG would be good.

  • +1

    Have a look at the Tech Epiphany YouTube channel. He has a a lot of comparisons with the Ryzen 4000 series gaming performance.

  • +16

    there's no ryzen 4000 laptop with a decent screen, it's so sad. This one has a 45% color gamut display: https://psref.lenovo.com/syspool/TempFile/cache/63acaccb-7c3...

    • at what % does it become a good display? 45% sounds awfully low but I don't know anything about this metric.

      • +4

        screens with good color cover 100% srgb, the 45% color gamut metric they use is NTSC I believe, for comparison 100% Srgb = 72%NTSC

        • +2

          yes, 72% NTSC is full sRGB coverage (although not really, specs often say 72% NTSC but sRGB is only 90 something percent covered).

          really, unless you do web design, or care about the quality of your photos a lot, 45% NTSC will actually be enough.

          movies are noticeably nicer with a color accurate screens though

          • @shabaka: This has been a pretty informative line of comments, thanks!

            Can you calibrate the colours to improve this or are you stuck with what you've got?

            • +3

              @Deviner: yes and no.

              no in a sense that if a screen is only capable of covering 45% of colour space, no calibration will widen its capabilities.

              yes in a sense that it's still beneficial to go through calibration process to improve colour reproduction. a calibrated 45% screen can look much better.

              in Melbourne here's a place that hires out calibrators. it costs 11 bucks for half a day, although calibration process really takes 20 minutes. of you do it, do it right and create at least 3 profiles for different white points (cool white, daylight, warm white). ever noticed how your screen looks a bit yellowish or blueish under different light conditions? switching between profiles will most definitely address that.

          • @shabaka: There are laptops with screens rated at 200% sRGB


            Best laptop color gamut (sRGB %)
            Alienware m15 (2019): 265%
            HP Spectre x360 (15-inch OLED): 258%
            Razer Blade 15 (OLED): 243%
            Dell XPS 15 (2019): 239%
            Dell Precision 7730: 211%
            Asus ZenBook Pro Duo: 203%
            Lenovo ThinkPad X1 Yoga: 201%
            Samsung Galaxy Book 2: 200%
            Gigabyte Aero 15 OLED: 200%
            Lenovo ThinkPad X1 Carbon: 199%

            • @morestuff: All expensive laptop.

              I have an old XPS M1330, even 720p but the screen is still quite nice compare with newer low/mid range laptop nowadays.

            • @morestuff: so what? only matters if you prepare something for printing and really want to make sure that what you see on the laptop screen is exactly how it will come off the press.

              I don't need that, few people do. most of them will have a 24+ inch monitor for the task and will be doing it in a room with controlled ambient lighting. so… having one in a laptop doesn't give me a hard-on

              full sRGB coverage, on the other hand, covers you for everything that goes online and is essential for digital content creators and consumers alike.

              at any rate, my intentions are to just save some money for a fellow ozbargainer. turn any 15-inch laptop into a dream machine that'll make your wedding photographer jealous.

    • +4

      It's a real bummer, anyone who's a content creator and is even remotely concerned about colour accuracy and sRGB coverage makes their options fairly limited, and almost entirely nonexistent if they want to go ryzen…

      • How about the redmibook 13? I dunno much about it, but I remember it being promoted with 100% srgb, which makes it serviceable for content creation right?

      • +1

        wait for a ryzen 4000 based laptop without a touch screen and put in any screen you want. that's what I will do

        best screens that go into design/CAD/whatever laptops are about $140 delivered, and installation is easy. I did lots of those

        • +5

          interesting, how do you know a screen is compatible with a laptop?

    • So 45% won't feel like desktop PC IPS screen.

    • So what would you recommend for something with a good screen and similar performance? What would be the price? Is a good option hooking up to an external screen for a better picture?

  • Showing as $28.94 delivery for me. May need to adjust title and update info OP.

    • +4

      get yourself a trial of prime if you are looking to buy.

  • +2

    If this had a thunderbolt 3 port, would've been perfect.

    • +1

      Isn't thunderbolt an Intel owned connector? Don't think we will see them on AMD laptops soon.

      • Actually it is happening soon. I can't remember who is doing it but someone is putting out Ryzen with Thunderbolt. On another note, why the need for Thunderbolt?

        • +4

          Oh that's cool. Thunderbolt 3 is awesome cause it can enable an eGPU, 10Gb ethernet, high powered docks, 6K monitors etc.

        • +4


      • Probably next year, as USB4, which is based on the Thunderbolt 3 protocol specification.

      • Intel donated TB3 a while back and it will be here pretty soon in the form of usb 4.0. Though not all usb 4 will be the same from what i last read, because the full implementation is a bit expensive for budget laptops

  • The Notebookcheck website says the AMD 4500U performance is "roughly in between that of the Core i7-8565U and Core i7-10710U — two high-end Intel processors found on some flagship laptops like the Dell XPS 13 series."

    • The 8565U is a 4 cores 8 threads chip, while the i7 10710U is 6 cores 12 threads chip. The 4500U is 6 cores 6 threads, it is in between due to overall less threads for multi core applications, however in single threaded tasks should be similar. The Ryzen 4600U would perform quite well and on par, if not better, than the 10710U.

      • The 3500U almost matches the i7 already

  • Wouldn't this get stopped at customs for GST or does amazon US include it?

    • +7

      Included in price

      Amazon Global Store Order Summary
      Items: A$916.17
      Delivery: A$0.00
      Total before GST: A$916.17
      GST: A$91.62
      Order Total: A$1,007.79

      • Cheers! This is cheaper than the education store deal then

        • +1

          Amazon is good in that aspect. Bloody fleabay charges a lot for their global shipping program. Easily 17% of total price for GST and "admin" cost.

          • +1

            @DisabledUser141524: That's because it's a profit centre - and not run by ebay. They sold off the exclusive rights to another company, who of course then charge their monopoly pricing because they paid ebay for rights to it.

            All about the money.

        • not really, the education store Ideapad is 200g lighter, so if you're looking to reduce weight that would probably be the way to go

  • Excellent, was holding off to get a touch screen laptop with a Ryzen 4xxxU processor to upgrade the wife's Lenovo

  • +1

    What does everyone do with old desktop/laptop? I have a couple.
    Edit: to justify a new buy.

    • +2

      Accidentally drop it off the desk.

    • +9

      Donate. Theres one for donating to refugees.

    • Sell it? If noone wants to buy it or it's not worth the time to sell, you probably need a new laptop…

    • +1

      Give it to me, ill pay postage.

    • Plug it into the tv as a slim HTPC. Alternatively I'm sure there's a relative/friend that could do with a PC.

      • Had nothing but troubles trying to use laptops as HTPCs. Gave up and went to SFF.

        • He wanted an excuse 👍
