Discussion NV Re-Enter ARM PC market in 2025!

[poke01]

Well, Qualcomm should be shaking in their boots now.

It’s not Nvidia’s hardware they should be worried about but their software prowess.

QCOM problem is that they're at crossroads. Their iGP is extremely efficient and performant for the Mobile market. It's been custom tailored through the years for this market demands.

But now they have to scale up Adreno to Desktop Class graphics computation. And there, the direction GFX is going is totally different from Mobile.

Mobile is basically TBDR + small batch FP16 workloads, with careful shaders that don't go overload. Desktop is completely different, with focus on plenty of bandwidth, Compute Shaders and next-gen geometry.

QCOM will need to design a GPU arch that can still be extremely area and power efficient for mobile while also being able to serve Desktop current and future demands.

So they have the same problem Apple does with its TBDR based GPU that doesn't perform/benchmark well in stuff (esp. games) designed for a traditional PC GPU pipeline.

So how will Qualcomm/Apple go about solving this ?

Switch 2 iGPU is 12 SMs with 12 RT Cores and 48 Tensor Cores, 1536 CUDA Cores/ALUs.

Nvidia iGP is supposed to be much bigger than this.

Radeon 780M is 768 ALUs/1536 with dual-issue. But much higher clocked. Faster than Switch 2 but should be slower than Nvidia WoA SoC.

RTX 4050M is 20 SMs.

Well Apple simply doesn't care, because they aren't concerned with running Windows stuff that requires high GPU performance. People will run native for productivity type tools, and they mostly don't game on Macs either.

Its only really a problem for Qualcomm.

I think all mobile gpus are like that, like the Mali G610MP4 was considered high end just 3 years ago. But in Linux running desktop apps it performs worse than a 2019 Vega 3 IGP.

Not sure what the problem is exactly, but i belive mobile just has other requierements, and these gpus are specially bad in FP ops. I belive it is because mobile gpus are still tailored for OpenGL ES.
