I have only read the AMD press release so far, but these cards seem like they are pretty cool. If the reviews show that the HD 4670 actually can give you twice the FPS in Crysis as the 9500 GT for the "same" (Newegg rebates are making the 9500 GT $25 less) price I will be impressed.
I will be working hard to get pages created for the new cards today so stay tuned.
Here is what the reviews have to say about the HD 4670 vs the 9500 GT in Crysis:
FiringSquad shows that the 4670 is exactly twice as fast at resolutions starting at 1280x1024 at Medium settings. HotHardware shows that the 4670 is twice as fast at 1280x1024 at High settings. Anandtech does not actually give their readers numbers, but it looks like the 4670 can give you twice as many FPS at resolutions at or above 1024x768 at Medium settings. TechPowerUp's findings are a tad outside the norm, but it looks like that is because they actually turned on AA at all resolutions except for 1024x768. This results in the 4670 only being twice as fast at 1024x768 and pretty close (12/22.5, 9/16.9 and 7/12.5) at higher resolutions with AA turned on. TweakTown's numbers are also pretty close. Running at High settings at 1280x1024 and 1600x1200 they recorded 13.56/24.33 and 9.8/18.22 respectively.
So it looks like this is one PR claim that is actually more fact than fiction. This must be the End of Days!
