I wanted to bump this and chime in that it really depends on the who's doing the benchmarks. I just read a well written benchmark test for the 7800GTX from GamerPC (they used a dual core processor btw) and the 7800GTX doubled the 6800U in most games and often did the same to the X850XT... that is the kind of perf one would expect and again I hope we see 5-15% more from the drivers, especially the DC optimized ones

The test system was only 1 gig of ram. They needed 2 gb for those high resolutions for BF2. That thing eats memory for breakfast!!! Especially 1600x1200 with AA!!!

I think it's against the law to go blabbing about specific things your former employer was doing - they make you sign some sort of non-disclosure agreement when you leave. He would be able to give insight into their "general" strategies though.

Check this out.

Battlefield2 Pure speed (no AA no AF)

1024x768............90.7
1280x1024..........82.6
1600x1200..........54.5

Battlefield2 4xAA 16XAF

1024x768............89.3
1280x1024..........72.5
1600x1200..........61.3

Definitely something fishy with that result - it doesn't make any sense and is inexplicable.

Although it seems like they updated the article, because the 1600X1200 result for the X850XT PE now is 66.9fps and the 1600X1200 4X/16X result is 57.2 .

Some interesting stuff in Far Cry as well: the Pier map gives the X850XT PE victories (or ties) in all cases over the 7800GTX, while in the research map, anything above 1280X1024 (AA or no AA) the 7800GTX lays the smackdown on the X850XT PE.

LOL


and an X800xt gets an FPS boost from no AA to full AA/AF

OMG Conspiracy!!!!!! Shens on the whole article!!!

Time for everyone to relax and look at the bigger picture here: 7800GTX winning almost everything, X850XT PE putting up a good show and even stealing a few.


Personally I think it's good to see how well some of these GPU's do (all the 16-pipe cards seem to do well in most high resolution cases). It goes to show that paired with a good CPU (ie a fast Athlon64), you can get your money's worth with an X800XL and above or a 6800GT and above.

seems there are plenty of mistakes, but i really dont expect xbit to be faultless

they test 17 gpu's in 6 different ways on 30 games

thats over 3000 seperate benchmark runs......theres bound to be errors somewhere

If the article is generally innacurate which I think it is (ie, anand's BF2 shows about 1/2 the performance of the X850) than its obviously useless...

I think they're FarCry results are pretty accurate. Doing my own testing between the two cards (X850XT PE & 7800GTX), I get pretty close to the same fps. Sometimes the X850XT PE comes out on top and some times the opposite.

The only other game I tested was HL2. Apparently I'm CPU limited at 2.85GHz because the results are very close between the two cards at 1680x1050 4AA/16AF.

I thought it was absolute scientific fact the human eye can't see over 60? I call shens on this - aka BS...........

Incorrect. That is probably one of the biggest myths that run around the internet gaming forums these days. I decided to look it up, because it was widely considered that anything over 60fps is good enough for gaming. While I agree that it is "good enough" It certainly isn't above our limit. For instance, I can tell a different between 60fps and 100fps, but the different is barely noticable. I believe this could fall under "diminishing returns".

According to http://amo.net/NT/02-21-01FPS.html">this</a> link, the human eye can detect up to 1/220th of a second.. That is pretty incredable.

Another reason I know that the human eye can detect over 60fps is due to the refresh rate on monitors. 60hz or 75hz will give me major eye strain and an instant headache. However, 85hz seems to have no ill affect on me.

With that said, I think it is pretty anal to say that 60fps isn't extremely enjoyable/playable for games.

Quote from that Article
The USAF, in testing their pilots for visual response time, used a simple test to see if the pilots could distinguish small changes in light. In their experiment a picture of an aircraft was flashed on a screen in a dark room at 1/220th of a second. Pilots were consistently able to "see" the afterimage as well as identify the aircraft. This simple and specific situation not only proves the ability to percieve 1 image within 1/220 of a second, but the ability to interpret higher FPS.
