AMD has officially announced their latest flagship graphics card in the Radeon HD 7990. This is a dual-GPU solution that is based off two 28 nm “Tahiti” chips. AMD says this card is different than the HD 7990 “New Zealand” graphics cards that were launched in Q3 of 2012 as it has a much lower power draw, requiring only two PCIe power connectors. The new card also features a dual-slot cooling solution, which AMD says is “whisper quiet”. Most of the “New Zealand” cards required three PCIe connectors and triple slot cooling solutions.
Both of the 28 nm “Tahiti” GPUs have all components unlocked. You have 2048 stream processors (4096 total), 128 TMUs (256 total), 32 ROPs (64 total) and the full 384-bit wide GDDR5 memory interface. Each of the GPUs hold 3 GB of memory, so you have a total of 6 GB. Each of the GPUs are clocked at 1000 MHz core and feature PowerTune with Boost. The memory clock is 6.0 GHz, which gives you 288 GB/s of memory bandwidth per GPU. The two GPUs work together by use of the PLX PEX8747 48-lane PCI-Express 3.0 switch.
Power comes from two PCIe power connectors. As far as outputs you have four mini-DisplayPort and dual-link DVI. This card can of course work in CrossFireX with any other HD 7990 out there. The card is loaded with a dual-BIOS so in case you mess up BIOS updates there is a fail-safe. With purchase of an HD 7990 AMD is giving away 8 games, they include Far Cry 3, Far Cry 3: Blood Dragon, Crysis 3 Hunter Edition, Bioshock: Infinite, Tomb Raider (2013), Hitman Absolution, Sleeping Dogs, and Deus Ex: Human Evolution. Official pricing on the card is $999, which puts it on par with NVIDIA’s GeForce GTX Titan.
Ohhh yeah…here are some reviews of the card!
