DirectX 10 compliant GeForce 8800GTX and 8800GTS headed your way

DailyTech's 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 G80 based products as the GeForce 8800 series. While the 7900 and 7800 series launched with GT and GTX suffixes, G80 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 G80 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.

Power requirements for the G80 were detailed in an earlier DailyTech article.

sound a lot more promising than previously

i do prefer a unified approach because i approve of GP-GPU usage, and the more generic the processor the better.

i wonder the if the variable 128MB+64bit vs 256MB+64bit memory that leads to 640MB+320bit vs 768MB+128bit memory is a result of separating IQ fucntions like AA from general resource usage?

with the GTS you get 8x super-duper AA for FREE
with the GTX you get 16x super-duper AA for FREE

doesn't make a lot of sense if its for something like the Geometry Shader portion of the GPU, because you would be basically saying to the GTS user that they should really only consider their new card as a very fast DX9 card, as its a bit crippled in DX10............

regardless, i will await the 0.65u refresh for a less power hungry version.
and hopefully a return to lower clocked but fully functional GT versions as i hate buying something with crippled hardware.

Man, I can't make sense of your numbers...
And I don't think anyone else can either...

It's possibe they've got those odd traces going somewhere other than the core, but my bet's they're all going to the core.
There's no reason why not.

AA isn't free without a dedicated AA unit, and even then, free quality enhancment comes at a price premium.

The 'free' AA of the XBox360 works with a set maximum framebuffer resolutions & perspectives of something like 1080p at 16:10 or 16:9? So, some 'smart' memory is able to perform the antialiasing on the framebuffer within 10MB...
One day that might come over to PCs, but it isn't here yet...
