Default Re: GTX 285 To GTX 480 Upgrade Performance Problems

I went from a 285 to a 570 and was blown away, so something doesn't seem right here. Could just be vsync though, just a thought.

Something is just not right because the 480 is a lot faster card and if you play at 1920x1200 ,you should see a big increase.I had three 280 and went to three 470's and seen a big increase .I ran just one card for a while and it was faster then my 280 which was a BFG OCX so it came overclocked,and a default 470 was faster.Sounds like that 480 is;nt running to it's potenial.But there are some older games that the 470 was just around 10fps faster,but I could turn the FSAA to max and the aniso to 16x and those games looked great and ran smooth.

Post Re: GTX 285 To GTX 480 Upgrade Performance Problems

Well, i have been doing more tests during the last weeks, swapping in & out the cards, and i found the 480 to be faster in some scenarios, but slower on others. Overall, the 480 might be faster, but, i'm not happy with a card that is faster only sometimes.

According to my custom tests, my 285 is around a 15-25% faster when the application is bound by the texture sampling units, and the 480 is around a 40% faster than the 285 when the application is bound by shading power.

So, this is complicated because, to run 1920x1200 with high level of AF, you really need a lot of texture power, because you need to filter more texture samples, but also, you need the shading power, so, the decision is not easy.

I have been reading about the differences between the 480 & the 580, and it seems that i might be right, because nVidia increased the texture filtering performance in the 580, as i can read @ anand or xbit:

Personally, i'm going to keep using my 285, and i'm going to consider this 480 as my little mistake.

And if somebody wants a cheap 480, it's on sale
