AMD today launched the AMD Radeon HD 7990, the world's fastest graphics card powered by two GPUs and designed for gamers who want to take their PC gaming experience to the highest level.
Based on AMD Graphics Core Next (GCN) architecture with AMD Eyefinity technology, the AMD Radeon HD 7990 graphics card promises to deliver unrivaled performance for playing the latest DirectX 11 games in extreme resolutions and multi-monitor configurations.
By combining two of the world's most advanced GPUs with 6GB of GDDR5 memory, AMD Radeon HD 7990 is the world's fastest graphics card. It supports up to six simultaneous displays with AMD Eyefinity technology and is the ideal graphics card for gaming on Ultra HD displays (4K resolution). At 100% utilization, AMD Radeon HD 7990 GPU's quiet triple-fan cooler is more silent than a typical library.
The new card enables gaming enthusiasts to play the latest PC games at maximum settings: for instance "Tomb Raider" with TressFX Hair enabled, or the "Crysis 3" in 4K resolution.
AMD's 7990 is a dual-Tahiti part, placing two of flagship GPUs on a single PCB to make a single card. Each GPU has all 2048 stream processors, 32 ROPs, and full 384-bit memory buses. Joining these GPUs is 6GB of GDDR5 RAM, split up between the two GPUs for the 7900-series standard of 3GB of VRAM per GPU.
The 7990 supports AMD's PowerTune Boost technology, which is giving the card a base clockspeed of 950MHz, and a boost clock of 1000MHz. The memory is clocked at 6GHz, the same as the 7970GE. This makes the 7990 very close to being a 7970GE Crossfire setup on a single card, clocked just 50MHz below AMD's single-GPU flagship card.
AMD's 7990 has an official TDP of just 375W.
The card also includes AMD?s ZeroCore power technology, which was introduced with the GCN family. ZeroCore allows AMD to almost completely shut off slave GPUs when they're not in use, which in turn allows AMD to further reduce their idle power consumption. The biggest benefits are found in multi-card setups since this allows the fans on those slave cards to be shut down. Consequently this pushes the idle TDP of the 7990 down to around 20W.
