ATI's New Radeon X850 and X800 Lines: A Smorgasbord of GPUs

- GPUs
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.

Man, It's way too confusing buying a card these days. There were already way too many ATI model numbers out there, and now this! Why can't they have an entry, Low Mid-range, High Mid-Range and high-end card and leave it at that.sophus - Wednesday, December 1, 2004 - link
model numbers are out of control. just go look at pricewatch.com and get bombarded by all of the models...i've heard that the purpose of the all the numbers/acronyms is to confuse the consumer into buying a "newer" part, read: more profitable for them.
the prices are getting too high. $500 for a card?! too much money for a (practical) gamer's most frequently upgraded part.
also, the availability for these cards is way too low. How long after the release do we have to wait until we can actually see these in stores? is demand that high and supply that low? is there a leak in their bank accounts? are their manuf processes too high?
a small tweak in their product and they demand top-dollar? or rather, "well this NEW product is just a little bit better then our last one. so instead of lowering the price on our OLD product, we'll just set the bar higher for our NEW product."

lol

#31Software HDTV decoders/encoder require working DxVA (i.e. ATI cards) for best performance, and sometimes to work at all. For people intersted in going the HTPC route, the video processor is very important, just not to you.

extremely unimpressive. My 6800 is still fine.Regs - Wednesday, December 1, 2004 - link
This does not look like a refreash to me. Just seems more like overclocked parts trying to win the performance crown that "no 'one'" can afford. I expect Nvidia to do the same. ATI even has the nerve to charge 400 dollars for a 12 pipe design. At least have it include Dual Dvi. I know it may not need the extra 4 pipes enabled, but it just seems like their taking you for a ride for a few extra MHz.Araemo - Wednesday, December 1, 2004 - link
#24:I stand corrected, though iDCT is VERY old tech, that nVidia had around from at least the geforce 4 series(if not the gf2 series), and ATI has had since sometime in the RAGE series.
And the "Motion compensation" sounds like what ATI has enabled via their drivers in a couple aps (Divx Player and Realplayer, if I'm not mistaken.)
Motion estimation is what I was thinking the only new use was, my mistake. Though I DO hope that nvidia at least has iDCT working, if not the motion compensation as well. The main selling point I saw w/ regards to the video processor was the ENCODE.. since I've never had a cpu usage problem while decoding a video.. even on a pentium 2 running windows 2000.
#26: I don't think 'decent' is the right word.. their drivers are decent, they just aren't fast.
I draw the distinction because of the number of video cards I've had with UNSTABLE drivers. I am very happy with the stability of the Catalyst 4.x series drivers.
That said.. nVidia has stable AND fast openGL drivers.. hello ATI?

#4, it's not worth getting worked up over anyone's video processor at this point. Nvidia's 68xx processor may be broken, but even if it worked, it doesn't make a difference. There are not any MPEG4 decoders on the market that can use either company's card, and WMV acceleration on my X800 Pro is having no impact: frame rates and CPU usage stay the same. And let's not even talk about hardware assisted encoding...The whole "video processor" idea has so far turned out to be a joke from both sides.

#10 the USD has lost 33% of it's value since GF4 days so in reality Vcards are the same price just your dollar is'nt worth anything.
