DirectX 10 compliant GeForce 8800GTX and 8800GTS headed your way
hands-on with the GeForce 8800 series
continues with more information about the GPU and the retail boards. The new NVIDIA graphics architecture will be fully compatible with Microsoft’s upcoming DirectX 10 API with support for shader model 4.0, and represents the company's 8th generation GPU in the GeForce family.
NVIDIA has code-named
based products as the GeForce 8800 series. While the 7900 and 7800 series launched with GT and GTX suffixes,
will do away with the GT suffix. Instead, NVIDIA has revived the GTS suffix for its second fastest graphics product—a suffix that hasn’t been used since the GeForce 2 days.
NVIDIA’s GeForce 8800GTX will be the flagship product. The core clock will be factory clocked at 575 MHz. All GeForce 8800GTX cards will be equipped with 768MB of GDDR3 memory, to be clocked at 900 MHz. The GeForce 8800GTX will also have a 384-bit memory interface and deliver 86GB/second of memory bandwidth. GeForce 8800GTX graphics cards are equipped with 128 unified shaders clocked at 1350 MHz. The theoretical texture fill-rate is around 38.4 billion pixels per second.
Slotted right below the GeForce 8800GTX is the slightly cut-down GeForce 8800GTS. These graphics cards will have a
GPU clocked at a slower 500 MHz. The memory configuration for GeForce 8800GTS cards slightly differ from the GeForce 8800GTX. GeForce 8800GTS cards will be equipped with 640MB of GDDR3 graphics memory clocked at 900 MHz. The memory interface is reduced to 320-bit and overall memory bandwidth is 64GB/second. There will be fewer unified shaders with GeForce 8800GTS graphics cards. 96 unified shaders clocked at 1200 MHz are available on GeForce 8800GTS graphics cards.
Additionally GeForce 8800GTX and 8800GTS products are HDCP compliant with support for dual dual-link DVI, VIVO and HDTV outputs. All cards will have dual-slot coolers too. Expect GeForce 8800GTX and 8800GTS products to launch the second week of November 2006. This will be a hard launch as most manufacturers should have boards ready now.

I think I'll wait for the 8900 series or whatever comes after the initial line-up, when they've figured out their bit-width and memory sizes and they release amounts that more directly correspond to texturing levels which generally run 512, 1024, or 2048. Not half-assed 640 or 768.
These numbers are 384/320 because their current manufacturing technology limits them to that. Once they get past those limitations you'll see cards sporting a much more 'normal' amount of bit-width and RAM, such as 512-bit with 1024MB DDR3.
That's when you'll see me investigating their cards further. Not to mention my 7900GT KO runs everything I play fine. ;)

Not really, a 384Bit Memory Interface is already another added level of complexity, were not going to be exploring 512Bit interfaces at all this generation, due to cost.
I rather have a 384Bit interface over the 256Bit one though, it does represent a good increase in bandwidth nonetheless.
Not to mention if the Geforce 8900 is a optical shrink of the 8800 there will be less room for the BGA connections for a complex memory interface such as 512Bit making it unfeasible.

Good thing ATI was building for the future so they can be last and slowest again eh Coldy?
