Lightning Fast, and CPU Bound

The high performance of cards like the Radeon X850 XT Platinum Edition dictate that, even on today's fastest CPUs, they will be CPU bound at resolutions lower than 1600 x 1200. To prove this we've taken three GPU limited benchmarks, Half Life 2, Doom 3 and Far Cry, and showed their performance scaling vs. resolution using the X850 XT PE on an Athlon 64 4000+:

So what does this tell us? It tells us that these high end cards are CPU bound up until 1280 x 1024. It is only at 1280 x 1024 that the X850 XT PE becomes GPU limited and even more so at 1600 x 1200. It's for this reason that we conducted all of our performance tests today at 1600 x 1200.

ASUS nForce4 A8N-SLI Deluxe Motherboard
AMD Athlon 64 4000+
1GB Corsair DDR400

NVIDIA ForceWare 67.02 Drivers
ATI Beta Catalyst Drivers 8.08-041111a-019256E (no Catalyst version has been assigned to this package yet)
Windows XP Service Pack 2 with DirectX 9.0c

All performance tests were run at 1600 x 1200, some benchmarks were also run at 1600 x 1200 with 4X AA and 8X AF enabled.

To continue our recent trend of looking at head to head comparisons between GPUs first and then looking at the broad spectrum of performance we begin by evaluating the impact of each one of ATI's new GPUs individually starting with the flagship, the Radeon X850 XT Platinum Edition.

    Yeah, this product naming is getting out of control - I don't even want to take the time to try to get them straight. I'll wait until everything's actually available, then try to see what the best option in each price range is. Right now, though, I have to go lie down - trying to remember what product is which gave me a headache.

    I would like to know too since we 6800GT's in a CAD environment and haven't had ANY problems with them.

    Any chance of seeing high res testing again?

    #9, how is the 6800GT "slightly unreliable"?? Ive had one for months and have no "reliability issues."

    I'm looking into that X800 now, as a possible budget upgrade, so I don't have to switch over to nVidia and get the 6600GT AGP.

    The X800 XL has some potential if it OCs well. The 6800GT is still the best option though, if you go PCI-E.

    Worst refresh release ever! A minor bump in core/mem does not equal 50 bucks more.

    Im thinking that the agp x800 cards are not going to fall in price at all, these pcie only cards are not competing against them so it makes sense(for ati) to keep prices high for both the x800 and x850 cards.

    Now lets hope nvidia comes out with a 500/1200 6900 ultra :)

    Considering the fact that both ATI and Nvidia are technological think tanks, you'd think they could do a less confusing job of naming their cards. :|

    pricing for the "high end" cards is utterly ridiculous...the (so called) high-end (X850) which is only a refresh of current tech is totally overprized, has dual slot cooling etc.....

    And...R520 is already taped out...

    Who pays $520 for this stupid card which, not even has SM3.0 and is only marginally better than previous versions ? Retards ?

    I miss the days of $200-$300 video cards being the top of the line (Voodoo2, TNT2, Geforce 1-4). I dunno why anyone would want to spend any more than this on a video card unless they've got money to burn.
