Folding Forum

So a while a go I made a toppic that fah doesnt run at the highest memory speed that is possible on my card and that its only benefitting a little bit from the memory speed so my question was does this rule also applie for hbm 2.0?

I heared that GPU memory speed is not so important for folding. It is more about shader count and GPU clock speed. So it doesn't matter if a GPU uses GDDR5(X) or HBM(x) memory.

AMD Vega will rock because of its 10 TFlops similar to GTX 1080. We will see when benchmarks are available.

When running a game, you expect your video to have a high frame-rate while displaying high resolution, high color images. That video data stream depends on fast memory. FAH does not produce high quality video data. Both FAH and your game use the shaders to calculate the 3D data which can be turned into visual images but those 3D calculations depend mostly on the speed of the shaders, not on memory speed.

In other words, shader speed and count are the gating factors (bottle-neck) for FAH performance, so memory speed has little impact on performance, as noted above.
