The next codenames to remember: GT200 and RV770

After the NVIDIA financial analyst call last week, the company briefly hinted at its upcoming roadmap this year. 

AMD's RV770 architecture, set to launch this summer, will be immediately followed by a new graphics architecture from NVIDIA, codenamed GT200.  GeForce 9900, as it's been dubbed, is not simply a derivation of G92 like the current GeForce 9800 GX2 and GTX offerings.

NVIDIA has been extremely tight-lipped about GeForce 9900, as it overlaps considerably with its current high-end offerings.  NVIDIA's latest flagship products, the GeForce 9800 GTX and GeForce GX2 only made their debut last month.  Unlike the GeForce 9900, these cards were once again based on the G92 die -- nearly the same GPU used in the GeForce 8800 GT. 

Original NVIDIA roadmaps put the GT200 launch in late Fall 2008. However internal memos sent out to board partners in early March detail that the GT200 processor has already been taped out.  The same document alludes to the fact that the GT200 chip is very stable, and has been ready to ship for reference designs for several weeks already.

The company gave no reason for the tentative roll-in, but with AMD launching the successor to successful RV670 (Radeon 3850, 3870) this summer, it seems entirely plausible that NVIDIA anticipates another close race. 

AMD partners claim Radeon RV770 will make its debut this summer under $300. NVIDIA's 9900 is currently scheduled as an ultra-high end adapter to be priced higher than the GeForce 9800 GX2 offerings, which retail for more than $500 today.

Channel partners indicate that the 9800 GTX and GX2 will begin phasing out next month in preparation for the GT200 launch. Both companies have made promises to show demonstrations of their next-gen cards at the Computex Taipei trade show on June 3, 2008.

Most solid RV770 specs to date.

Kris said he didn't list much info on RV770 because he doesn't know much about it, which is understandable. I've been researching it as a possible upgrade on my X38, and here's what I've found over the last few months.

"RV770"
- 55nm.
- ~830M Transistors; approx. 25% increase in size [vs RV670].
- DX 10.1/SM 4.1/OGL 2.0
- 480SP or 800SP* per RV770 (R700 therefore = 960 or 1600).
- 256-bit mem interface.
- 32 TMUs (finally!)
- 24 or 32 ROPs.
- AA performance 'fixed' from R6xx lineage.
- Launch parts (May/June) will use GDDR3.
- Later models (July) will use GDDR5 (ATI's original goal), as it will not be ready before then.
- 2GHz (4GHz DDR)++ GDDR5 speeds enable triple-digit GB/s bandwidth despite 256-bit interface.
- 800-1000 MHz core clock.

*I can agree with everything on here except the debate of 480 vs. 800 SP. It stems from differing interpretations of RV770 details. One number is certain: 480. Some people say it is 480 SPs, while certain insiders understand it to mean an increase of 480 SP with respect to RV670: 800 total.

Either way, the better texturing/ROP performance is long overdue; this has always been ATI's shortcoming. Also good to know is that due to Rx7xx's Rx6xx heritage, driver optimizations should carry over from one to another; HD2K/HD3K owners won't be left in the dust from driver optimizations.

ATI is getting better and better all the time.
With this performance for a reasonable price they really think about their customers!

That's assuming that the price is reasonable.

ATI made the X3x00 series, Nvidia followed suit with the 9800's. In ATI's case it was to remove the unsuccessful X2x00 series from its product line. The X3800's are definitely a step forward- not much faster, but far more efficient (allowing for X2 cards). If they continue this trend I believe that their new cards could be a BIG success. Okay, all of that was common sense... unlike Nvidia's 9800's. Just call them 8900's and reserve the 9x00 series for the new technology, don't blacken its image with overclocked 8800 cards! At this rate they're going to have to rethink their naming strategy soon.

Geforce 10800 ?
Geforce10 X30, X60, X90 ?
... Voodoo?! 3DFX?!

Well, as mentioned in the article, it seems that the channel partners are expecting a $300 price, which sure sounds nice in my books.

Finally more than 16 TMUs.

It's about time. ATI might continue to get my business since maybe next Christmas I might build a new PC. Don't know if I'll go AMD or Intel for the processor though. The Intel will probably be faster, but AMD is a good bit cheaper. You can get a quad-core from AMD for $200. Intel starts at $280-ish. And it seems Intel motherboards are often far more expensive than AMD ones.

List for Intel starts 280ish, but the Q6600s have been available for $180-200 for a few months now (even retail boxed).

At that price, AMD is completely non-competitive.

Would love to see a link for that price. Newegg is running $245.
