View Full Version : GeForce 6800 performance with 16-pipelines/ 6 shaders!!

I just used Rivatuner to enable 4 more pipelines and 1 extra vertex shader on my new BFG GeForce 6800 OC. I have to admit that the performance increase is greater than I expected. My card is ALMOST as fast as the 6800 GT I had in it. I can't tell much of a difference in my games between the 6800 and 6800 GT. I'm also overclocking my 6800 to 350MHz core and 760MHz memory. The core speed is the same as the 6800 GT, but the memory is slower. That's the only difference now.

I was able to get the 6800 at Best Buy for only $249 with a copy of Far Cry. That's a great deal considering I now have a card that's very close to a $400 card in performance. I'm not an avid gamer, but I'm more than happy.

BTW, I heard it's a matter of luck when enabling pipelines. Sometimes they're disabled because they're defective. I hope I'm not prematurely happy, but my games have all been working great.

Here's the performance differences I see so far:

3DMark 2005 4410 with 6800 GT, 3226 with 6800 12-pipes, 3616 with 16

3DMark 2003 10376 with 6800 GT, 9009 with 6800 12-pipes, 9888 with 16

Doom III and Quake III run the same.

I think I would see more of a difference if I had a fast CPU. My P4 3.06GHz is starting to show its age.

wow $249 AND farcry? That's a pretty sweet card there.. enjoy. :)

The difference comes in when you overclock both cards. I mean yea sure a 6800 with 400/900 frequencies is good and *almost* gt performance. But if you OC the GT to like 425/1150, you leave the 6800nu in the dust. Anyway, whichever budget works for you. Both cards are really good, and that 6800nu at fry's (or was it best buy?) has a really nice price.

That was a great buy at $249, especially if you didn't already have Far Cry. I didn't know that the extra pipelines could be enabled through a software program. I know that the X800 Pro's pipelines cannot be enabled through this method. Am I wrong?

One thing I didn't consider is that I'm limited to 128MB of RAM with my card vs. the 256MB of the 6800 GT. This will be a limitation with games like DOOM III and HL2, but I don't really see a big difference with DOOM III vs. when I had the 6800 GT.

plus i think its standard ddr not gddr3, but still its a great card and it seems to be working out well for you.

DDR and DDR3 are the same speed clock for clock. The only difference is that DDR3 runs cooler and can reach much high clock speeds.

I wish people would bench games instead of well synthetic benchmarks.

My thoughts exactly. Overclocking my 6800NU (form 12/5,325/700 to 16/6,400/850) showed lots of gains in synthetic benchmarks, but very little in terms of a real-world performance boost.

I would say your P4 still got a fair bit left in him... Don't under estimate him. However just don't show him any AMD 64 benchmarks

Darn, the prices don't want to drop here and I just got tired of waiting that to happen.

6800NU - 330
Asus V9999GT/TD - 350
6800 GT - 450

Those are the lowest prices atm. I will probably buy the Asus hybrid so I don't have to rely on my luck to get the full pipes and shaders. :retard:

Since you live in europe: Buy one in germany. I bought my Point of View 6800 Gt for 385 excl. shipping there.
6800NU's are around fr 254+.

Most of the shops ship within europe. If you don't speak german just send them a mail. They usually speak english and shoudl ship the card anywhere withing the EU.

Ouch, didn't know that the 6800NUs were that much cheaper in Germany. (omg) I had only checked the GT prices a few weeks back and decided that the price difference was not worth the trouble.

Too late though, 'cause I have this V9999GT/TD right next to me now, waiting to be mounted. :naughty:

I thought I'd add in my Chaintech AA6800 (6800nu) pipeline enabling and overclocking results as well. I posted this previously in another forum, but figured the performance increases might be interesting to someone here.

I took my Chaintech AA6800 OC'd to my everyday settings of 430/920 paired with my A64 3200+ at 2.55ghz and did a couple benchmarks with it running the standard 12p/5vp and then with a rivatuner enabled 16p/6vp. FarCry Bench was the training level timedemo @ 1280x1024 with Ultra detail and 2xAA/4xAF, average of three runs. Doom3 was just the demo1 timedemo at 1280x1024 with high detail with 2xAA/8xAF, 2nd run. I also dropped my card down to standard 6800nu speeds (325/700) to see how big a difference it all makes with overclocking compared to leaving it all stock.

..................12/5.........16/6.........12/5:6800nu clocks
3dMark03:.10676......12549........9164
FarCry:..... 38.27fps. 46.75fps.. 31.79fps
Doom3:..... 70.1fps... 79.6fps..... 58.7fps
