If AMD ever makes an APU die with 3D vcache on it, 100% of them be going in mobile gaming handhelds like the Ally. They see desktop APUs as the value products.

Does 3D cache significantly increase power draw?

Yes but also no, because they have to run the cores under it at a lower voltage (and slightly lower clocks) to avoid thermal issues, so it evens out. I really do not think they'll ever do this to a low-power APU (or a desktop APU) anyway but if they wanted to burn some R&D money on a minuscule market for some reason, I think they probably could. The X3D chips they sell are ultra-efficient for what they do.

kliras posted:threadripper announcement finally official  I'm really tempted by the 24/48 because my setup needs stupid amounts of IO but not a trillion cores. I started off being annoyed that they cut 16 lanes out from the old threadripper before I re-read it and realized it's 48 PCIe 5 lanes with an additional 40 PCIe 4(?) They need to answer if these are arcwelded to the first MB they're installed in the way server chips are.

BlankSystemDaemon posted:NUCA is a loving mess. What on earth are you complaining about here? It's the laws of physics which dictate that the costs, both energy and time, of accessing memory resources go up as the memories get bigger and/or further away. NUMA and NUCA aren't lazy designers deciding to make life difficult for everyone else, they're just consequences of this reality. The only way to achieve true uniformity in a large system is globally restricting performance in all cases just because you don't want CPUs to be capable of running faster while working with local (or relatively local) data.

Mmmmm.... disagree. Figure them to show up in Instinct MI APUs first, and then get binned down to the consumer market for something like Steam Deck 2.

Would you even be able to use the 3dvcache as VRAM? Because if not I don't see the point - the IGPU is going to hold back the machine

There's ways to work around the bandwidth bottleneck though - spinning the iGPU off to a separate chiplet and adding/stacking cache on the IO die, 7000 series style cache dies, stacked HBM (???). We'll see what AMD deems cost effective once Strix Halo is released.

Adding even 2GB of HBM to the APU that's dedicated to the graphics would be pretty neat

Not sure where else to post this, but details on Qualcomm's upcoming Snapdragon X Elite have leaked: https://videocardz.com/newz/snapdragon-x-elite-leak-12-core-oryon-cpu-4-6tf-adreno-gpu-lpddr5x-av1-and-wifi7 My understanding is that this thing is meant to power Windows ARM laptops. Is the ARM branch of Windows no longer a joke? Won't most apps and games be wholly incompatible? I'm confused as to how this is supposed to be a good idea. What's the benefit of using an ARM processor over an x86 one?

windows ARM can run x86 binaries under emulation, but the performance is nowhere near as good as rosetta since non-apple hardware lacks the TSO extension that rosetta leans on if qualcomm does TSO and microsoft updates their emulator to use it then maybe they can get somewhere

I'd bet that for a whole lot of usage cases, if you've got an ARM browser and MS Office, then the substandard emulation for the long tail of other applications is fine. Come to think of it, anything that's .NET and JIT-ed anyway will be completely fine already too. I know that ARM is making inroads and gaining territory in the server segment, and clearly Apple has had enormous success. The last time that x86 and ARM went head to head was the Atom Phone days, but that was a weird market and time and Intel may well have sabotaged themselves. For Windows laptops, even if ARM doesn't gain market share quickly it'll limit AMD and Intel's profit margins.

Iirc HP and Lenovo launched windows arm on snapdragon laptops in 2021. Battery life was very good for Windows (15hrs+) but you ran into the expected issues with emulation Seemed good enough for web browsing and Office work

I played around with a number of engineering apps I use under Windows 11 ARM emulation using my M1 Max; I had an issue with a few, but by and large the apps worked well and it was still pretty snappy.

I've used CFD software (Ansys, Simflow) with varying levels of success, and then a few AutoDesk products (Revit, AutoCAD) that worked depending on the version, strangely enough (2022, 2024 worked for me, while 2023 had issues). I've used a few others too (WaterGems, Flow2D, HEC-RAS) without any real problems. I installed and ran Solidworks briefly using a prior model, but haven't really used it at all. It ran after I made a few adjustments I had seen online, but it did feel a bit slow at times with the model I used.

ended up picking up this board for a build: https://pg.asrock.com/mb/AMD/B650E%20PG-ITX%20WiFi/ I assumed there would be a small air gap between the GPU backplate and the M2 fan assembly... but with the 3090 FTW3 Ultra, they are fully touching. Probably not great for my M2 drive that the 3090 also has the highest backplate temperatures in GPU history. That M2 cooling tower has become an M2 warmer... but the 3090 will love it! (theres lots of work arounds to this that ill probably do, just thought it was funny)

The platfrom stuff -- "Is my CPU too hot? Overclock or undervolt? How do I run 4 sticks of ram at high speed?" -- is pretty domain-specific and can really get into the weeds. GPUs on the other hand pretty much run themselves, and there's TBQH very little difference between brand. They're either working or hosed, and when something is hosed there's not much you can do besides wait for new drivers / RMA the card.

Cross linking from the Cities Skylines thread, my CPU scaling testing in Cities Skylines 2 with a 3090 at 1080p highish: Those 7800X3D results are painful, lol. Getting matched by a 1700.  Game is laughably GPU bottlenecked.

Why is a sim game GPU bottlenecked? I play DF so I know I might not have much of a leg to stand on here, but surely a sim game doesn't need that amount of visual fidelity.
