The Radeon HD 7950 Monica BIOS 1 was a graphics card by AMD, launched in January 2012. Built on the 28 nm process, and based on the Tahiti graphics processor, in its Tahiti PRO variant, the card supports DirectX 12.0. The Tahiti graphics processor is a large chip with a die area of 352 mm² and 4,313 million transistors. Unlike the fully unlocked Radeon HD 7970, which uses the same GPU but has all 2048 shaders enabled, AMD has disabled some shading units on the Radeon HD 7950 Monica BIOS 1 to reach the product's target shader count. It features 1536 shading units, 96 texture mapping units and 32 ROPs. AMD has placed 3,072 MB GDDR5 memory on the card, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 925 MHz, memory is running at 1250 MHz.
Being a dual-slot card, the AMD Radeon HD 7950 Monica BIOS 1 draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 185 W maximum. Display outputs include: 1x DVI, 1x HDMI, 2x mini-DisplayPort. Radeon HD 7950 Monica BIOS 1 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution.
