5800U Doom3 Shocker!

High Q/0X8X
8X6=58.6fps
10X7=42.4fps 10X7 2X 8X=35fps
11X8=36.3fps
12X10=29.5fps

Med Q/0X0X
10X7=50.4fps 10X7 2X0X=41fps
11X8=42.3fps


Of note: check out those 10X7 and 12X10 High Q scores! Why should we care?
5800U vindication
5950 10X7=43.7fps 9800XT 10X7=46.6fps
5950 12X10=30.9 9800XT 12X10= 31.9fps

Sweet! The 5800U turns out to be the functional equivalent of the 5950 and 9800XT at Doom3- gotta love it!
 
I remember reading Carmack's blog comments during Doom3 development that he was using a 5800 in his primary rig for testing. He also said that the noise of the card bothered him too. So yes D3 was probably coded primarily on a 5800.

Your memory is good, he used it so he could develop the nV paths, and because he hit the limits on the 9700Pro instruction set.. (and the noise did anger him)
 
Nice, good older cards can still get it done, but I don't think these results should be too suprising.

Other than the newest feature sets that came with the Geforce6 line of cards, is the new 6600GT essentially the performance equivalent of an FX5800U?

IIRC:
FX5800U - 8 pipes / 500 core / 1000 mem on 128bit bus
6600GT - 8 pipes / 500 core / 1000 mem on 128bit bus

This dawned on me while I was looking around trying to judge how much of an impact the 6600GT 128bit membus would have on its performance.
 
Clock speeds and memory indeed look to be identical (though one is DDR2 and the other 3), but the architecture is wildly different.

6600GT - 8x1/16x0 pipes, SM3.0, rotated grid AA
5800U - 4x2/8x0 pipes, SM2.0(b?), ordered grid AA, horrible at DX9 and bigger performance hit with AA/AF

I don't know about that... I'd like to see where he said that. Considering the game runs just fine on ATI hardware... AND can be made to run even better with a pretty obvious tweak for anybody who knows anything about the differences between ATI and nVidia GPU's, and how to write shaders.

Bout the only thing I can think of that would have been possible on nVidia hardware and not ATI is nVidia's Ultrashadow stuff... which isn't even being used (yet) anyway...
 
As far as i know the slowest GDDR3 bin speed for samsung is 1.1ghz, so i could see some easy OCing potential as well on the memory.

Correction the bins are 1.0ghz, 1.1ghz, 1.2, 1.3, 1.4, 1.5, 1.6. With 1.3ghz+ being rediculously expensive.
 
Doom3 is a lot scarier playing with a 5800U also - it constantly sounds like you are being chased by a giant hair dryer, for some reason 😉 . That sick b@stard John Carmack!

NP Jeff-

For developers doing forward looking work, there is a different tradeoff --
the NV30 runs fragment programs much slower, but it has a huge maximum
instruction count. I have bumped into program limits on the R300 already.

If Carmack would have kept the nV30 path (
NV30 ( full featured, single pass)
Click to expand...
) nVidia would have had a hands down sweep of Doom3 performance and IQ. Everyone in the world with a nV3x card would have superior performance to anything 9800XT or less, and the nV40s would own the high end. It still puzzles me why he dropped it and left the nV10 and nV20 paths.

LOL-literally!

But it's...it's...an evil hairdryer, with a finger bone for an on switch, and a spooky glowing pentagram on the side!

You could say it's just a hell-borne demon screaming at you constantly - quite unnerving. The fact that his devlish cry sounds a lot like a full-blast hair dryer is just a minor detail... 😉
 
Finally, the 5800U shows some potential....j/k

I'm not that shocked. After seeing 9700pro D3 marks, I figured the 5800U would be as fast if not faster.
 
I'm more shocked seeing 9800's keep up with 5800/5900 after the preliminary benchmarks showing them getting beat down

When he dropped the NV30 path, he mentioned in a .plan update that the Detonators (as they were then called) had progressed to a point where NV3x could run the ARB2 path on par with R3x0. Maybe he was hoping to avoid the situation that we have now (where one architecture is clearly superior) but it sucks that we're not able to use our cards' full potential.

The 5800U is also a UT2K3 monster, and eats RTCW for lunch as well. As far as the blow dryer comments go, it sounds like that on the audio and video you can see/hear on the web but in person it sounds exactly like a Delta 60mm "screamer".

Ugh. I have one of the Delta Screamers sitting in my spare parts box. I think I'd rather listen to the hair drier.

Seeing as it only happens in 3D mode, and beyond benching I wore cans, I was uneffected. Besides, the extreme sensitivity everyone seems to have developed to sound, is lost on me. I like white noise, of course i don't live in a little dorm room, or at home with my parents in a bedroom where I'm stuck next to my PC all night either 😉

Punisher- you're not a wall away from your mom and dad, or in a 10X10 dorm room?! I always thought you were? 😉
