I have nothing but respect for long-time folders that got their points the hard way. From what I’ve read, the reason GPUs are capable of such a high Points-Per-Day is not only that modern GPUs are quite powerful, but also because the GPU work units are different. The GPU work is considered more valuable by Stanford, so they bumped up the points to encourage people to do GPU folding. The same is true of the Playstation 3 work, but I believe they actually lowered the points for that work (they arbitrarily chose 1000 PPD) because otherwise the casual PS3 folders would crush everyone else. Even now I think most of the FLOPS come from PS3 users.

By the way, if anyone has a Facebook account, there’s an application that lets you track your points on your profile. I just joined and I’m the only team member right now:

Here is the noon update for F@H stats. The three GPU classes outproduce all other CPUs since they run small routines incredibly fast, over 700 times as fast as a CPU.

Not to take away from general purpose CPUs. There are certain calculations that cannot be done by GPUs that tie the entire project together. Both are needed to advance science.

I also suspect that if Stanford could convince Sony to change the PS3 to that it ran F@H in the background 24/7 that Stanford would leap for joy. Imagine the FLOPs if 3,000,000 PS3's joined the project. Wow.

Active CPUS are defined as those which have returned WUs within 50 days. Active GPUs are defined as those which have returned WUs within 10 days (due to the shorter deadlines on GPU WUs). Active PS3's are defined as those which have returned WUs within 15 days.
*TFLOPS is the actual teraflops from the software cores, not the peak values from CPU/GPU/PS3 specs. Please see our main FAQ, FLOPS FAQ, PS3 FAQ, NVIDIA GPU FAQ, or ATI GPU FAQ for more details on specific platforms.

Just joined the Facebook page.

I’d like to hear more about your system. In 6-7 days you have more points than my 3 years of folding.

Thanks for joining on Facebook. Extra exposure of the team will help.

I currently have three boxes folding, all using only NVIDIA GPUs to fold. The CPUs are usually working on other distributed computing projects. One box has four 9800GX2 cards (built specifically for F@H), one has two 8800GS cards, and one has a GTX 285 card. Most of the big points generated by single users are all from GPUs, although the SMP client also generates nice points if you have a dual-core or quad-core processor. I built the dedicated system because I'm impatient, and because it was a good excuse to buy another computer.

BTW, the latest F@H thread is here.
