News: 7800GT - only 20 pipelines

[Cooper]

Some bad news for all those who waited 7800GT, hoping to gain 7800GTX performance level with OCing. VR-Zone (http://www.vr-zone.com/?i=2441&s=1) has reported that 7800GT will have only 20 pipelines. Yet vertex shader and ROP quantity will be common to 7800GTX.
Also nVidia don`t plan to release 7800 Standart - there still to many 6800 to sell.

they wil be unlockable ....watch my words ;)

Aye,

Unless they do like ATi and make each level of their X900 series have different core revisions. To be unlockable, doesnt it have to be the same core, with pipes just disabled ?

is this 100% truth mmmm strange

[turtle]

Just a couple speculation questions out there...

1. Could this mean NVIDIA is having problems with yields on the 24pipe cards? Perhaps these are cards with a broken quad? Or of course they could just be a gtx with a quad disabled (like already stated) because that would save on production costs or even perhaps this design was meant to be the 7800 vanilla (with normal DDR or something) but was changed (to the GT with DDR3) because of stock piles of 6800's left?

2. Do the pipes really matter? If you look at a 7800gtx with the same clocks as a 6800gt or ultra, they really arn't that far apart, are they? I heard like 7-8% tops. I heard the real differance is from the clockspeed/memspeed upping plus the 40+ geometry clock tweak. If these cards are 20 pipes and clock as well as a gtx after overclocked, wouldn't that only put them 3-5% tops behind a GTX at the same speed? If so, they could still be a good deal if they overclock well. If it's a 400/1100 stock speed like they say, I'd imagine the ram will overclock just as well as the gtx and the core shouldn't be too far off, it's only a 30mhz hit.

Granted, this doesn't make them as appealing as they wouldn've been, but at the price they seem to at, and if they clock well, they may surprise everyone even though it only has 20 pipes. One quad isn't going to make a world of differance as long as it clocks as well. But if it's the crappy dies from a wafer, ie ones that have the worst clocks + some with broken quads, then you get into questionable territory, where a overclocked 68gt or Ultra might put up a pretty good fight next to it. Obviously the new gen would win, but the 6800gt would still be the best bang-for-buck, especially after the release of the 7800gt drives the prices of the 6800 series down.

What do you guys think? I find this fairly interesting. This could go a couple different ways.

its funny how Nvidia has full GTX's out, in quantity, extremely available... yet people still want to say they are having problems with yeilds...

I think people often just wanna grab for any excuse that makes sense that makes such and such company look like they are just lucky when they get a working top of the line product...

maybe they just lazer cut a pipeline quad, dumped the 1.6 NS ram, to 2.0, lower the clock speed, and give it a cheap heatsink, so it wasn't just dumbed down GTX...

either way, now I know what card, I wont be getting...

[Cybercat]

Wow, for that much of a handicap, even $450 is unreasonable IMO.

lol you just described the worst outcome possible. Probly it will be just cards which core didnt pass the test to be GTX. I like to think the pipleins would be just software masked. You proabably right about the heatsink that would cut down cost since good heatsink cost $.
But it's all speculation untill the cards come out. Any chance of them being AGP or Nvidia will never realease AGP card agein? I realy dislike their marketing strategy by pushing SLI to sell their chipset. 7800gtx would rule in my Dothan sys and i realy dont feal like upgrading anytime soon. My GT plays all the games maxed out on 1280/1024 4xaa 16xaf. Still i would upgrade the card if it would be possible just for fun. There were rummors G80 would comeout AGP but somehow i find it hard to belive. First MF that comes out with PCI to AGP bridge will make alot of $ since majority of the systems will stay AGP for a while

they wil be unlockable ....watch my words ;)

Lets hope so. :D

[iddqd]

Well, how can they avoid problems with yields? I mean, 302 million transistors.. pretty good chances to have defects. And, AFAIK, G70 is a 32-pipe chip. So far all we've seen is 24. That's 8 pipes locked.

[troid]

They aren't worth the 450$

i preffer to wait until nvidia announces the gpu

you were wrong :slapass:

Nice one, reviving this thread just to satisfy your big ego. Who knows, in the end you might even be wrong! :slapass:

Yeah. Like it was with 6800LE@Vanilla@GT. :D

exactly. thank you. i just ran accross the thread and thought id bring it back up :p:
