WTF !

According to VR-ZONE the 7800GT will have 20 pipes and 400 mhz clock.

I hope this is not true .

Think of all the fun people will have trying to unlock the 4 pipes :)

why is 20pipes so bad? it's a model lower than the gtx. 20 pipes seems reasonable to me.

Additionally, it's only fractionally below 24 pipes at 335 for pixel fill if it is actually at 400 Mhz, so I don't see it as a huge loss. It would be a shame if they reduced the number of vertex pipes though.

sad...gone are the days of simply OCing the GTs to make them the higher end part :(

This is a cheaper part, do you really expect a gt to run at 429mhz with all 24 pipes? Sheesh.

Just for the record, 335 Mhz @ 24 pixels per clock is 8040 fillrate., 400 mhz at 20 pixels per clock is 8000 fillrate. If it maintains the 8 vertex units it will be a faster solution due to having better geometry performance than the old 335 mhz rumored specifications with an almost identical fillrate. In other words. This is a better solution overall. Everyone needs to start thinking beyond pipelines here and actually looking at the shader/fillrate performance instead. So if the entire part is better than what the original rumors suggested. Why are we complaining?

we are complaining becasue you can't OC it as much. The 7800GT would have been an awsome OCer if it had the same 24 pipes the GTX did.

Thats a big assumption. Since you have absolutely no data of overclocking abilities of the 7800GT in its prior form.

agreed, and lets give the card a chance before we put forward any verdict.

Didn't this same site say the card was to be released last week?

If it still has all 16 ROPS with 20 pipelines at 400mhz, I'm betting it will keep up with the gtx quite nicely in most games.

Good point! I guess people got spoiled by the GT but it's not some GOD given right. It's not like XL's could overclock to PE specs and they still sold a bunch.

Except prior experience. We've seen the X800 Pro vs 6800GT. Which one was the better option? The one with the reduced pipes and increased clock or the one with more pipes that had the chance of being overclocked?

Why wait for data to see the obvious? More pipes is better like more cache on an A64 is better; you can overclock to make up the difference in speed but you can't make pipes out of thin air.

Maybe we can turn the pipes on, maybe we can't. But that is a lot harder for us to make up the difference for than clockspeed. Even if there is a smidgen of better in the 20 pipes and higher speed part, the reduction in potential for overclock makes it a bad trade.

I say make the 7800 standard a 20-pipe 350 part. Make the 7800 GT a 24 pipe 350 part. Keep the 7800 GTX a 24 pipe 430-70 part. And make the 7800 Ultra a 500-530 24-pipe part.

Standard 299.99
GT 399.99
GTX 499.99
Ultra 599.99

Toss in a 512 model GT slightly overclocked at 499.99 and a GTX 512 overclocked model at 699.99, a low end 7200 (based on the improved pipelines of 7800 with about the same number and improvements to turbocache) at 99.99, 7600 (12 pipes) at 149.99 and 7600 (16 pipe)GT at 199.99.

Excellent product range. Probably as good as anything ATI might come up with. Bada boom, bada bing.

Under that logic. X800XL's should overclock to X800XTPE value because they have the same pipeline configuration. The simple fact is you do not know the voltage core of the 7800GT, you do not know if it will come power connector. You are betting on something that isnt obvious. Under the circumstances. The 20 Pipeline part @ 400 mhz with 8 vertex units is better part than a 335 mhz 24 pipeline part with 8 vertex units.

If it's only 20-pipes, that's certainly expensive for $499.99. Futhermore, as useless as a 7800GTX is right now, this makes a 7800GT even more useless. I'm all for high-end, but what can;t be played now on a 6800 Ultra? Furthermore, ut2k7 demos were scratching 30fps with a 7800gtx, so this GT wont even get you a steady 30fps. (depending on what settings they were using of course) I might jump ship and go r520, especially if it's 32-pipes. That should have the strength to go through 2006's blockbuster titles.

X800pro didn't lag much behind 6800GT and in this comparison you can't forget you're talking about different architectures, R420 is less efficient than NV40.
Why wait for data to see the obvious? More pipes is better like more cache on an A64 is better; you can overclock to make up the difference in speed but you can't make pipes out of thin air.
I'd rather have a higher clocked venice than a lower clocked San Diego.
Maybe we can turn the pipes on, maybe we can't. But that is a lot harder for us to make up the difference for than clockspeed. Even if there is a smidgen of better in the 20 pipes and higher speed part, the reduction in potential for overclock makes it a bad trade.

Why should a 20 piped 7800GT have a higher reduction in potential for overclock than a 24 piped one. I say G70 with 20 pipes active is more relaxed than a 24 one so it might be easier to overlock a 20 piped than a 24. The reduction in potential for overclock would happen for both cause their dies are of lower quality than 7800GTX ones and gpu voltage would be lowered on both; it happened with 6800GT. Of course more 4 pipes makeup for the difference in clocks but I wouldn't say 20 pipes is disappointing.

Note: I'm assuming the number of vertexs and ROPs would remain the same.

Yeah, and it's 4 more than an Ultra...I fail to see how this is "bad"

I dont think it is that bad .
I have just expected nvidia to launch a full feature card with 24 pipelines and lower clock speed so i could oc it to 7800GTX levels just like we all oc the 6800GT to 6800 ULTRA levels .

That's exactly why they probably disabled the 4 pipes. They want hardcore gamers to buy the top end card, not the one below it and OC it. I'm sure Nvidia lost a lot of cash on the 6800 Ultra because almost everyone bought the GT. It made sense to get the GT in all aspects, and they wanted to make a good GT card, but not of equivalence to the GTX.

Sorta glad they did this, I would have felt ripped off if they introduced a slightly lower clocked 24 pipeline card for $100+ less than the GTX.
