The GeForce 8800 GTS 320 was a performance graphics card by NVIDIA, launched in February 2007. Built on the 90 nm process, and based on the G80 graphics processor, in its G80-100-K0-A2 variant, the card supports DirectX 11.1. The G80 graphics processor is a large chip with a die area of 484 mm² and 681 million transistors. Unlike the fully unlocked GeForce 8800 GTX, which uses the same GPU but has all 128 shaders enabled, NVIDIA has disabled some shading units on the GeForce 8800 GTS 320 to reach the product's target shader count. It features 96 shading units, 24 texture mapping units and 20 ROPs. NVIDIA has placed 320 MB GDDR3 memory on the card, which are connected using a 320-bit memory interface. The GPU is operating at a frequency of 513 MHz, memory is running at 792 MHz.
Being a dual-slot card, the NVIDIA GeForce 8800 GTS 320 draws power from 1x 6-pin power connectors, with power draw rated at 143 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 8800 GTS 320 is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 269 US Dollars.

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
MAD - ADD+MUL
