PS3 Folding Better than PC Folding?

post #1 of 17
Thread Starter 
I'm not to sure, but i think that, the PS3 is faster, but can only do a limited type of WUs, and that the PC is slower but can do almost any type of WU.
Is that right? If not tell me how it goes heh.

Reason I'm asking is cause in one of my classes today the kid behind me was like "i'm doing that Folder at home thing on my PS3" so i started talking to him about it and he kept saying the ps3 is sooooo much more powerful than the PC. I explained that it was only because of the parallel processing of the PS3 and that while it is faster, it is not better than the PC. He wouldn't listen, as he is a stupid snobby rich sophomore.
So i told him "shut up, your stupid and don't know anything" and turned around to talk to my friend. He didn't even know what GPU stood for and was mocking me... the nerve...

I hate noobs who think they know everything. It gets on my nerves. And yes, the PS3 is supposed to be much faster, but I don't know the specifics. I'm pretty sure it has to do with the uberleet Cell processor.

Average PC now fold using SMP: 24 average hours per 500k WU
PS3: 8 hours and they're trying to reduce that amount of time.

As far I know, you're correct. The PS3 is VERY fast at what is does, but can't do everything, like a Ferrari. The PC is like the family van... it goes slow, but can do almost anything.

Isn't GPU folding still better than PS3 folding?

This is what XBOX 360 is trying to do. GPU is more powerful than a CPU. But it depends on which CPU and GPU that is being compared.

XBOX 360 will win over folding because of their GPU.

The Cell Cpu architecture allows it to perform MANY floating point calculations at any one instant allowing it to fly through work units. As said the PS3 at current is limited to what it can fold, However it will fold much faster than any current desktop CPU.

the GPU is faster according the the site if you run the numbers for how many TFLOPS vs how many CPU's

Faster means nothing unless you are comparing the same WU.

They designed the PS3 WUs to only take 8 hours. Yes they do certain calculations faster, the WU still was only made to take 8 hours so that Stanford could get the results back quicker. Since basically all the PS3s have roughly the same specs as far as folding is concerned, they all should be able to do 3 X 330point WUs per day running 24/7.

SMP WUs are designed to take 24 hours on there bench machine. They go faster or slower based on your specs.

GPU WUs are designed to take 8 hours each on there bench machine. Your GPU and CPU will affect the speed of your GPU folding so you should get between 2 and 3 WUs per day done.

Here is a PPD breakdown of what you can expect folding with SMP, GPU, or PS3. I dont know much about single clients because the single clients I run are on very low end machines.

PS3 running 24/7 = ~990ppd (This is based on standard PS3 specs)
GPU running 24/7 = ~990ppd (I get 680 on mine because I run it on a crappy CPU)
SMP running 24/7 = ~4000ppd (This is on my quads in Linux)

On july 22 when you can get a Q6600 for $266, you will be able to build a SMP folding rig only (no fancy addons like sound, graphics, and such) for about $550.

Unless the PS3s drop way in price. My ~$550 bucks will go to rigs that can put out 4000ppd rather than a PS3 that does under 1000ppd.

If you have a PS3 for gaming, great, fold when you are not gaming.

If we are talking about pure calculation power, the GPU spanks everything hands down.

If we are talking about ppd, Quad Core SMP folding hands down.

If you are talking about the easiest folder to manage, the PS3 wins hands down.





Dezixn,

Ask your friend when the last time his PS3 made over 5Kppd like my main folding rig can.

Dezixn,

PPD isn't the real benchmark on how fast a machine folds.
Check here:
http://fah-web.stanford.edu/cgi-bin/...?qtype=osstats

You'll see that the PS3 has turned in about 550 TFLOPS to date, while Windows machines have turned in about 186, and GPUs about 55. In termps of production per CPU, we get the following numbers: PS3 - 17.1 GFLOPS; Windows - 0.95 GFLOPS; GPU - 58.6 GFLOPS (based on active CPUs). Clearly, the GPU has the most power, nearly 3.5 times that of the PS3
