The Quadro FX 3800 was an enthusiast-class professional graphics card by NVIDIA, launched on March 30th, 2009. Built on the 55 nm process, and based on the GT200B graphics processor, in its GB2 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 GT200B graphics processor is a large chip with a die area of 470 mm² and 1,400 million transistors. Unlike the fully unlocked GeForce GTX 275, which uses the same GPU but has all 240 shaders enabled, NVIDIA has disabled some shading units on the Quadro FX 3800 to reach the product's target shader count. It features 192 shading units, 64 texture mapping units, and 16 ROPs. NVIDIA has paired 1,024 MB GDDR3 memory with the Quadro FX 3800, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 600 MHz, memory is running at 800 MHz.
Being a single-slot card, the NVIDIA Quadro FX 3800 draws power from 1x 6-pin power connector, with power draw rated at 108 W maximum. Display outputs include: 1x DVI, 2x DisplayPort. Quadro FX 3800 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 198 mm in length, 111 mm in width, and features a single-slot cooling solution
