Rollo's Doom3/6800NU/6800GT/GT@NU Benchmarks

Page 6 - Seeking answers? Join the AnandTech community: where nearly half-a-million members share solutions and discuss the latest tech.
The graph that your link points to is borked. Has numerous wrong entries in the grid. So don't go by that.
All 6800's have 222 million transistors. The GT has 16 texturing units not 12. Pixel fillrate for a GT would be higher than a 6800nu, I just don't know the exact numbers. The 6800nu has DDR memory not DDR2.
There may be more wrong entries, but this was just from a quick glance.

Cheers.
 
Looks like Extreme tech still has not properly corrected their mix up between the 6800 and the GT.
 
At any rate, i'm finding almost no real performance difference between the 6800 and the 6800GT here.. I've got both cards sitting here, and have swapped them out four times.

My last timedemo(demo1) on the 6800NU overclocked, was 36FPS @ 1600x1200 4xAA 8xAF, maxed settings. My last GT timedemo was almost identical - but the GT is not overclocked in the slightest. The 6800NU is running at 401/855 on overclocking, and is at 47'C consistantly.

I think i'm taking the 6800GT back, I don't see the value in paying 100$ +/- more for it, and not really realising any massive "OMFG" difference. Rollos tests pretty much solidify it, that at least in Doom3, the extra pipes and junk don't seem to do anything and the primary difference between the cards in real world gaming, is the clock/ram speeds. Which can be offset with some simple coolbits overclocking.

I play at 1280x1024 2x/4x 99.9% of the time when I game anyway. I'm about to run a Timedemo on the overclocked 6800NU at those settings and see how she goes.
 
Well I managed to get the 6800NU up to 51.3FPS in Doom3 @ 1600x1200 2xAA + 8xAF max settings. Which is pretty impressive to me.

I slightly overclocked the gpu and ram a bit more, turned up a couple fans a bit(specifically the side fan aimed at the GPU sink), defragged my hard drive, and moved my ram to more aggressive timings, and added about 100mhz to my CPU. Seems to be 100% stable with these settings, in both 3DMark2003 and Doom3.

I can't complain about that one bit.

I would not take STALKER as an accurate messure of video cards. There could be many issues like cpu limited, driver limited, game limited, ext ext... Any game that scores over 200 FPS with 1280x1024 enabled I wouldnt trust as a benchmarking pad. Not to mention the game is still months away. Who's to say the 6800NU couldnt score even more? It's all in the hands of the game developers and not the hardware companys.

Far Cry is of right now likely the best game to benchmark on. What ever happen to these benchmarks? Looks like the 9800xt got it's ass handed to it. There is no excuse there.

What I want to see is you overclock the 6800NU...

I purchased the 6800NU because of the price.. $299, it was eVGA brand, the only brand I buy, and I had $65 in gift cards to drop its price even more.. Then I ripped out my 9800Pro, sold that for $190, sold the VGACooler on it for $10, Sold Farcry for $29, and well, the 6800NU was a FREE upgrade. =)

Anyway, I dropped in my 6800NU, overclocked it to 400GPU 855RAM, and well, it smokes.. Obviously the 6800 and 6800GT are pretty close in performance, 3-10FPS or so difference. My question is, how well would a overclocked 6800 do against the normally clocked 6800GT? I'm betting it would close the gap completely, negating the 3-10fps difference while saving $100+. Another thing to consider is this:

http://www.extremetech.com/article2/0,1558,1624005,00.asp

The 6800NU has 4 more texturing units than the 6800GT, and the 6800NU runs at 5.2Gx/sec on both pixel AND texture fill rates, whereas the 6800GT runs at 4.2Gx/Sec on both.. Meaning to me, there are some give and take going on with both cards, depending on the setup. Which might explain why the extra pipes and ram mean nothing in speed when you clock the GT down to NU speeds, the NU's other areas where its better, maintain its performance against an evenly clocked GT..

you have the 6800NU and 6800GT mixed up

Just want to say i am new so i hope i did this right. I was wondering what kind of hardware you were running when you did that test.

Also, this ati and nvidia fight needs to stop just as the intel and amd. I hope i am not stepping out of line when i am saying this do to i am a new member.

Wow I had forgotten this thread.
The hardware was A64 3000+/and either 768MB PC2700 or 1GB PC3200. Can't remember when I bought the RAM. SB Audigy 2 , reference 6800NU and XFX 6800GT.
 
Well for a 280 buck card that is not bad. i say might as well go for the 6800 till the gt goes down.
with a awesome cpu and some moderate overclocking you could beat it, and hey isn't that what overclocking is about, Sticking it to the 800 cpu or 600 graphics cards.
