Folding Forum

Qualcomm is now reviewing the technical feasibility of bringing the necessary compute stack to the Snapdragon X2 for FAH.

They are aware of the GROMACS requirements and are looking at how to implement the precision needed for molecular dynamics.

Thanks for the reality check on the engine specs. You're right, I should keep the distinction between OpenMM for GPU and GROMACS for CPU clear. My bad on the crossover, I'm just following the tech updates closely. Joe, I agree the Neural Engine's INT8/FP8 isn't the fix. My point with the M5 projecti...

One more quick point on the efficiency of this platform going forward. Based on the M5 architecture specs we’re seeing for 2026, the potential for a green folding lab is huge. The base M5 already delivers over 4x the peak GPU compute performance for AI compared to the M4, and a lot of that comes fro...

So far all of the Intel processors with iGPUs still have a detectable PCI ID. Same exists for the AMD processors. When or if that will ever change we will find out, but the client detection code still works for them for now. Don't underestimate stability either. F@h has a fairly small group of soft...

Your computer is doing fine because windows on arm scheduler is so messed up, that it sets priority wrong. In normal windows if you set FAHCore to anything other than normal, things just start to go to hell ;) Thanks for the info. But since we cannot expect Microsoft to improve things anytime soon,...

I've now finished testing FAH PPD with this fix. Before I got 35.000 PPD, now I peaked at 111.720 PPD. That's a performance increase of more than 300%! Also, below are some performance increase estimates for other Snapdragon chips: X1 Elite (84-100) up from 55.000 to 165.000 PPD And then the upcomin...

Important update! I can see that on my x plus Snapdragon laptop, even with all my 8 cores enabled for FAH, the default WIndows Task Manager is the lowest "low" priority, and setting it to normal doesn't fix this. You have to set the priority to "Above Normal" and you'll get 100%...

Thank you for the detailed historical context, Joe_H. I appreciate the clarification regarding the reliance on OpenMM for the current GPU folding cores. ​It is understandable that historical instability in Apple's OpenCL implementation has left a mark on development. However, my goal in bringing up ...

For several years, the exclusion of Apple Silicon iGPUs from the Folding@home whitelist has been justified by the claim that macOS lacks stable OpenCL support and that the M-series chips cannot handle the high-precision FP64 math required for scientific folding. As of early 2026, these technical exc...

FP8 is so outdated. Everyone knows FP4 is most important :D Haha, very true! While the AI PR teams are racing to 0-bit precision, we're still over here demanding those solid 64-bit floating points. I'm eager to see if the Xe3 architecture finally breaks the 'iGPU curse' with its native FP64 support...

Thanks for the feedback.

I'll provide the PCI ID as soon as the hardware arrives in early February so we can test the folding stability.

I'm also looking forward to seeing those official developer notes to confirm exactly how the Xe Vector Engine handles FP64 in hardware.

You still haven't posted any link to any official Intel statements on this. Interpreting those statements depend a lot on who is making them and the exact wording. https://newsroom.intel.com/client-computing/ces-2026-intel-core-ultra-series-3-debut-first-built-on-intel-18a?hl= https://wccftech.com/...

No no, confusion is coming purely from Intel :) While their driver team is doing wonderful things, the rest of them are just talking for the sake of talking. They rarely distinguish between hardware and software emulation. They just state supported and leave it at that muziqaz, you’re 100% right to...

Do you havre a link to that official confirmation? I do know when originally announced the Xe2 Battlemage architecture it was going to have two series of chips - the Xe2-LPG for iGPUs and Xe2-HPG. Lunar Lake processors shipped with Xe2-SPG chips for their iGPUs and do not support FP64, the discrete...
