NVIDIA’s DX10 GeForce 8800GTX - G80 chip

Gentlemen, start your DirectX10 engines

DailyTech received its first looks at a GeForce 8800 production sample today, and by the looks of it, the card is a monster: at least with regard to size and power requirements.

The GeForce 8800 comes in two flavors, which we will get into more detail about over the course of the next few days. The first card, the GeForce 8800GTX, is the full blown G80 experience, measuring a little less than 11 inches in length. The GeForce 8800GTS is a cut down version of the first, and only 9 inches in length.

The marketing material included with the card claims NVIDIA requires at least a 450W power supply for a single GeForce 8800GTX, and 400W for the 8800GTS. Top tier vendors in Taiwan have already confirmed with DailyTech that GeForce 8800 cards in SLI mode will likely carry a power supply "recommendation" of 800W. NVIDIA's GeForce 7950GX2, currently the company's top performing video card, carries a recommendation of 400W to run the card in single-card mode.

NVIDIA is slated to launch both versions of the GeForce 8800 in November of this year. More details on the GeForce 8800 will be available later today on DailyTech.
Update 10/05/2006: We originally reported the GeForce 8800GTX and 8800GTS are 9" in length. The reference design for the 8800GTX is actually a little less than 11 inches. The GTX has two 6-pin power adaptors, the GTS has only one.

G80 Flavours

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.

Documents Leak NVIDIA's Quantum Physics Engine

NVIDIA is ready to counter the Triple Play

With the release of the G80, NVIDIA will also release a new engine dubbed Quantum physics engine. Quantum Effects Technology is similar (at least in spirit) to NVIDIA's PureVideo Technology -- a dedicated layer on the GPU for physics calculations. A few documents alluding to this new engine appeared on public FTP mirrors late last week.

Quantum utilizes some of the shaders from NVIDIA's G80 processor specifically for physics calculations. Physics calculations on GPUs are nothing new; ATI totes similar technology for its Stream Computing initiative and for the Triple Play physics.

NVIDIA and Havok partnered up this year claiming that SLI systems would get massive performance gains by utilizing additional GeForce GPUs as physics processors. Quantum may be the fruits of that partnership, though NVIDIA documentation clearly states that Quantum will work just fine without SLI.

NVIDIA's documentation claims Quantum will specifically compete with AGEIA's PhysX, yet does not mention who is providing the middleware. Given that there are only two acts in town right now, it would be safe to say Havok has a hand in the Quantum engine.

looks good,......

but i think its all about AMD and ATi when it comes to hardcore computer enthusiast,....

what would u guys get?

NVidia's DX10
or
ATi's DX10 ?

[fish]

para nako, i'll wait kung kinsa ang naay mas better offer. price to performance... which card would be the best buy is the best card for me...

[wikki]

i'll get DX affodable n price to performance ratio card thats great.

[darkwing]

high end pa man ni, wait sako sa mainstream DX10 cards

[Spec-V]

If I am still using my ASUS A8R32 MVP X3200 Crossfire Mobo...then its ATI for me. There's one istoryan here (forgot the name) that he said nForce Mobos have issues w/ ATI cards. He was right. My previous Gigabyte GA-K8N-SLI nForce4 SLI Mobo have serious issues w/ my X1900 XTX Vid Card.
