GTX470 Performance Test Part 1: Windows XP
After a long wait nVidia’s GF100 is here, and I decided to pick up a GTX470 as an upgrade for my GTX285 since I absolutely could not stomach the horrific noise levels from a GTX480. I have nothing against ATi, but I do prefer nVidia’s cards for gaming.
This article will conduct the tests on Windows XP, while a future article will retest everything on Windows 7 (64 bit), which I plan on installing soon.
But first, here are the specs for the two cards I’ll be comparing today:
Compared to the GTX285, we can see the GTX470 has a higher pixel fillrate and more shader performance, but it has less memory bandwidth, and seemingly less texturing performance too. In practice actual texturing performance should be better than the GTX285 due to improvements to the TMUs and caching. This was covered in our architectural analysis of the GF100, which I co-wrote.
With regards to estimated die sizes, the GTX470 is bigger than the already big GTX285, so it’s truly a beast. I think it’s safe to say that at least some of the delay in getting the GF100 to the market was because of manufacturing difficulties due to the chip’s extraordinary size and complexity.
Enough theory; let’s talk about the benchmarks. As usual my settings are somewhat unorthodox compared to the standard fare, because in most cases they’re the actual game settings I use when playing these games. There will be a total of 36 different games tested today.
