The GeForce 8800 Ultra was an enthusiast-class graphics card by NVIDIA, launched in May 2007. Built on the 90 nm process, and based on the G80 graphics processor, in its G80-450-A3 variant, the card supports DirectX 11.1. Even though it supports DirectX 11, the feature level is only 10_0, which can be problematic with many DirectX 11 & DirectX 12 titles. 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 paired 768 MB GDDR3 memory with the GeForce 8800 Ultra, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 612 MHz, memory is running at 1080 MHz.
Being a dual-slot card, the NVIDIA GeForce 8800 Ultra draws power from 2x 6-pin power connectors, with power draw rated at 171 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 8800 Ultra is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 270 mm in length, and features a dual-slot cooling solution. Its price at launch was 829 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 |
