The Quadro Plex 1000 Model IV was a professional graphics card by NVIDIA, launched on July 25th, 2008. Built on the 90 nm process, and based on the G80 graphics processor, 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. Quadro Plex 1000 Model IV combines two graphics processors to increase performance. It features 128 shading units, 32 texture mapping units, and 24 ROPs, per GPU. NVIDIA has paired 3,072 MB GDDR3 memory with the Quadro Plex 1000 Model IV, which are connected using a 384-bit memory interface per GPU (each GPU manages 1,536 MB). The GPU is operating at a frequency of 600 MHz, memory is running at 800 MHz. Its power draw is rated at 320 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Quadro Plex 1000 Model IV is connected to the rest of the system using a PCI-Express 1.0 x16 interface.

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
