NVIDIA Preparing GT300 Graphics Processor?

[nekrosoft13]

Hardspell reports that NVIDIA may have cancelled working on the G200b (the 55nm version of GT200). Details on this new DirectX 10.1 graphics processor trickled in, it has 384 shader units, uses a 45nm fabrication process and incorporates 1 GB of GDDR5 memory at 4.00 GHz (effective) while the core could be clocked at 800 MHz with a 2.00 GHz shader domain. NVIDIA hopes to take on the R700 and its successor which unreliable sources claim to be based on the Super-RV770.

Ohoh...

Sign me up for one. :D

Though this is completely out of nowhere and not very credible... :p

[MUYA]

Its too much to bring out. I never head of a GT300 taping out etc through the normal rumour circles of websites. If it has taped out, it will likely be another few months before it can be released, well after the R700 lanch.

They say the GT200b has already taped out..months ago and should be ready in the next few weeks?

[CaptNKILL]

Yeah I highly doubt the 55nm GTX200 card has been canceled.

They need to bring something else to the table as fast as possible. They'd lose a ton of market share to ATI if they had no competition for the 4870x2 other than the current GTX280 for the next few months.

Looks to me it's FAKE. If it was true this would be the best news for AMD/ATI in a long time.
It would allow them to stay on top with the HD 4870X2 till 2009 Q1.

The source of this tread is somebody forum post at VR-ZONE. The somebody (me3850) (http://forums.vr-zone.com/showthread.php?t=299648) claims his source is Hardspell.
I went to hardspell.com to search for the source and could not find it.

Strangely I found this at Hardspell:
NVIDIA to fully advance to 55nm in 2H08, says paper (http://en.hardspell.com/doc/showcont.asp?news_id=3714)
AMD RV740/RV870 will use 40nm technology (http://en.hardspell.com/doc/showcont.asp?news_id=3740)

The bottom line is they're all just rumors but this one (me3850) is the most difficult to believe.

[Toss3]

I think this could be true; a 55nm version of the gtx 280 could match an r700, but I'm guessing it won't - based on the previews of the 4870x2. Nvidia would know this as well, and with their stocks falling I think they'd want to do everything they can to take home this round.

Remember that the rv870 is also coming out at the end of the year. ;)

Good times for the consumer! (nana2)

I think it's a fake, but obviously, nVidia is working in the successor of the GT200.

+1 ;)

[Bearclaw]

If it is real and credible news, awesome. If not, then oh well. Like walterman said, obviously nVidia is working on a new card Whether it is the G300 or something else, we will see.

[Roliath]

If it is real and credible news, awesome.
This would be a beast of a card if it were true.

If not, oh well...move along folks

[Tr1cK]

I thought NV was skipping 10.1?

[Mr_LoL]

If it did come out with those specs it will be a beast. And will hopefully cost less than £300.

We got to know the related news but we are not so sure about this:


NVIDIA GTX 350
GT300 core
55nm technology
576mm
512bit
DDR5 2GB memory, doubled GTX280
480SP doubled GTX280
Grating operation units are 64 the same with GTX280
216G bandwidth
Default 830/2075/3360MHZ
Pixel filling 36.3G pixels/s
Texture filling 84.4Gpixels/s
Cannot support D10.1 .10.0/SM4.0
(nana2)

The card sounds great but I think it's fake though. Still, I have a feeling Nvidia's next card will be a beast.


I have difficulty believing the card will have a 512-bit bus and DDR5 at the same time. I mean, unless I'm wrong, wouldn't that be overkill? I would be easier and cheaper for Nvidia I guess if they made that bus smaller. (256-bit or 320-bit) Then again, I have little knowledge of these things though.

[walterman]

GDDR3 with 512bit bus peforms like GDDR5 with 256bit bus. A progress could be a 512bit bus with GDDR5, cause, on the actual nvidia architecture, if you lower the bus width, you are lowering the number of ROPs too, and thus, the AA performance.

Hmm.. I'm confused too.

Probably a Middle Eastern thing. You wouldn't understand.

I pee on thee.

Do u think this is a realistic specs ?

[hell_of_doom227]

Next Nvidia card has to use 512bit cause even GDDR5 running high speed on 256 would simply choke GPU itself. Heck not even GTX280 has enough bandwidth for its shader power.

[Heinz68]

It's more like specs for GTX 280x2 Which only few people believe we will see on the 55nm shrink.

[Ninja Prime]

Do u think this is a realistic specs ?

No, not even close IMO. Its flat out impossible in fact, for the die size and 55nm tech quoted.

Yes but not for the reason you give. The next Nvidia GPU will probably be 512bit because the way ROPs are tied to memory, dropping to 256bit would half the ROPs to only 16. Of course, if they physically dropped those ROPs from the die that would save them some space and make more a smaller die, which could run faster.
