GTX260 and Folding

[natermeister]

I'm currently buying 8800GTs, but looking at the price differences between the 9800GTX+ and the GTX260 got me thinking. How much more production does a GTX260 belt out over a 9800GTX+? I know that the GTX280 will pull down 7k+ ppd, and it's probably not even being fully utilized.

Just curious.

My 260 will/is doing 7k with an OC.

I'm not sure on the new 9800+ (I don't think they are much different, just less power hungry)

My GTX260 gets between 6580-7400 ppd depending on the WU. I have my shaders clocked to 1512 and that is probably as good as I could get it (without the shaders crapping out). You are right about not being fully utilized. I had a 16 stream processor Geforce 8500 running about 850 ppd that should put a 112 SP 8800GT in the 6000 range and the 192 SP GTX260 in the 10,200 range for ppd. Hopefully with more optimizations these (GPU and CPU) clients will scale to more processors better.

Where did I read that... something about the streams are capped right now in this version. Eventually they will open up the rest. I can't recall the # I remember reading it at FCF... ah well but yest there should be further enhancements coming.

Don't complain, you've got it alot better than us ATI guys. 800 stream processors and only puts out 1k PPD...

To be on topic, the difference in production really doesn't justiffy the price difference when it comes to GTX 260 vs 8800GT. Now, the 9800GTX+ doesn't even register in my mind since the advantage over the 8800GT is so small I wouldn't even consider it. Personally though, NVidia's policy of dictating the lowest advertised price on video cards is enough to make me not want to buy one of their products until they quit that. While it may not be good for my PPD, I occasionally do make purchases on principal (and my HD4870 is one beast with games.)

Same average for me, overclocked to 1512 as well. The GT200 architecture is limiting the shader speed to 1550 MHz. I hope the GT200b refresh will unlock this and get released before my step-up period expire. However, keep in mind that the proteins are too small to take advantage of all the 192 stream so when the bigger proteins get released, the GTX 2xx series will truly shine when the 8800GT will choke.
