GEFORCE 8800 GTX GEFORCE 8800 GTS REVIEW
Core 2 Extreme QX6700 (2.66 GHz) - > 12 000 points 3DMark06;

Athlon FX-62 (2.8 GHz) - > 10 000 points 3DMark06.
Power requirements:
Single setup
8800 GTX - 30 amperes 450 W
8800 GTS - 26 amperes 400 W
GEFORCE 8800 GTX 8800 GTS PRICES
GeForce 8800 gtx:
Frequency of video chip is 575 MHz. Which characteristic, 128 unfield shader blocks will operate at the frequency of 1350 MHz. As you see, strategy of the clock frequencies with different design for different functional blocks inside the video chip continues to excit with the new GPU.
The memory frequency of 1800 MHz DDR. the most amusing, that we will see on GeForce 8800 GTX memories of type Gddr-3.
Answer to the question "why not Gddr-4?" are in the video memory of GeForce 8800 gtx - such video card will have 768 mb memory. I.e., to the usual 512 mb. are added 256 additional mb. - most likely, for the needs of physical effects or other specific tasks. If GeForce 8800 gtx use memory Gddr-4 of this volume, price would be a lot higher and the card will be less attractive.
The memory bus also has uncommon word length - 384 bits. I.e., to the usual 256 bits with added 128 additional bits .this explains the U-shaped arrangement of the memory microcircuits around the videochip on the graphic map GeForce 8800 gtx.
Finally, the pair of speed characteristics: memory ensures the brandwidth og 86 Gbit/s, videochip fills rate equal to 38.4 with billion pixel per second.
GeForce 8800 gts (differs in terms of the modest characteristics):
Chip Frequency of 500 MHz.
96 unfield shader blocks, which work at the frequency of 1200 MHz.
Memory Frequency Of 1800 MHz DDR.
640 mb memory type Gddr-3 (512 + 128).
the 320- bit Memory bus (256 + 64).
The memory brandwidth 64 Gbit/s.
Both video card will support DirectX 10 and Shader Model 4.0, and also Dual- link DVI, HDCP, VIVO and HDTV
The second news is about the fact that video card on base of chip G80 will support the physics acceleration at the hardware level. Within the framework of the technology, called Quantum Effects (name can change in the final version), is implied the use a part of the unfield shader blocks of video chip G80 to calculate the physical effects. Strictly speaking, this confirms the previous data about the special features of G80 with the "physical" effects.
Possible to assume that those "additional" megas-byte of memory and the 128 memory bus were necessary for G80 exactly for the work with "physics". However, in the absence of clearly expressed "physical load" they hardly will stay in separate from the remaining resources of the video card.
It should be noted that the "physical" technology from NVIDIA can work also without SLI, on single video card. NVIDIA gives us to understood that Quantum will compete with AGEIA PhysX...
