The GeForce 8800 GTX was a high-end graphics card by NVIDIA, launched in November 2006. Built on the 90 nm process, and based on the G80 graphics processor, in its G80-300-A2 variant, the card supports DirectX 10.0. The G80 graphics processor is a large chip with a die area of 484 mm² and 681 million transistors. It features 128 shading units, 32 texture mapping units and 24 ROPs. NVIDIA has placed 768 MB GDDR3 memory on the card, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 576 MHz, memory is running at 900 MHz.
We recommend the NVIDIA GeForce 8800 GTX for gaming with highest details at resolutions up to, and including, 1280x720.
Being a dual-slot card, the NVIDIA GeForce 8800 GTX draws power from 2x 6-pin power connectors, with power draw rated at 155 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 8800 GTX is connected to the rest of the system using a PCIe 1.0 x16 interface. The card measures 270 mm in length, and features a dual-slot cooling solution. Its price at launch was 599 US Dollars.

Card Notes

518.4 GFLOPs when Multiply Operation is available.

SFUs: 16

G80 GPU Notes

Each Streaming Multiprocessor(SM) in the chip architecture contains 8 SPs and 2 SFUs.

Each SP can fulfill up to two single precision operations MAD per clock.

Each SFU can fulfill up to four operations SF per clock (these units can also handle single-precision floating-point multiplications per clock).

The approximate ratio of operations MAD to operations SF is equal 2:1.

The theoretical SP + SFU performance in single-precision floating point operations
[FLOPSsp + sfu, GFLOPS] of the graphics card with shader count [n] and shader frequency [f, GHz], is estimated by the following formula: FLOPSsp+sfu; f × n × 3.

Alternative formula: FLOPSsp+sfu; f × m × ( 8 SPs * 2 (MAD) + 4 * 2 SFUs ). [m] - SM count.

SP - Shader Processor (Unified Shader, CUDA Core)
SFU - Special Function Unit
SM - Streaming Multiprocessor
