some info on the new DX10 card from Nvidia:
Earlier today some information regarding the possible specs of nVidia's upcoming G80 based boards surfaced on VR-Zone, only to be "quietly" removed later. Thankfully X-bit labs managed to collect the information on the new cards and we can now present it to you below.
The most important aspect of the leaked documentation are the specs revealed:
- Unified Shader Architecture; - Support FP16 HDR+MSAA; - Support GDDR4 memories; - Close to 700M transistors (G71 - 278M / G70 - 302M); - New AA mode: VCAA; - Core clock scalable up to 1.5GHz; - Shader performance: 2x Pixel/12x Vertex over G71; - 8 TCPs & 128 stream processors; - Much more efficient than traditional architecture; - 384-bit memory interface (256-bit+128-bit); - 768MB memory size (512MB+256MB)
The unified shader architecture suggests, what the experts have been saying for a while now, that the cards will be support DX10.
According to the same, leaked, information the G80 will surface in November in two varieties, the GeForce 8800 GTX and GeForce 8800 GT priced at a mere USD 649 and USD 449-499 respectively. The GTX model (higher-end) will feature a 384-bit memory interface, a hybrid water and air cooler and 7 TCPs while the GT will have a 320-bit memory interface, a standard air cooler, and 6 TCPs.
No one has actually explained what TCP actually stands for although Techreport has uncovered an nVidia patent which refers to thread control processors. According to the same patent these TCPs will be used to set the function of the unified shader processors.
AWESOME indeed but a 'mere 649 USD' is not an easy consideration for me
DDR4? And I thought DDR3 was special, damn.
a bit to pricey, otherwise its nice
Captain Amerika;3246076DDR4? And I thought DDR3 was special, damn.
the ati x1950 thats is out right now got DDR4 ram...
Meh. Chances are I won't be using Vista therefore I won't really benefit from a DX10 card. Sounds nice, though.
It has DDR4 but only 768MB RAM. 2 7950GX2 in SLi can beat it no problem even if it's not DX10 combatible. Even 2 1950XT that are slightly slower than the 2 7950GX2 in SLi can beat it
well you need to remmber that the 7950gx2 uses ddr3 ram at 1200 MHz and that the x1950xtx uses ddr4 ran at 2000mhz so to put it simple ddr4 ram is faster then ddr3, that is what makes the x1950xtx cross fire faster then the 7950gx2...
give me a X1950 (the newest ATi card out there gddr4 2000mhz)
No no no the X1950XTX uses 512MB DDR4 at @1000Mhz and the 7950GX2 uses 1024MB DDR3 at @1200Mhz and that makes THE 7950GX2 FASTER
