Advanced Micro Devices yesterday presented its new flagship graphics card Radeon HD7990 by the codename Malta, which is intended to be used in most modern computers to meet the needs of the game’s most demanding gamers. AMD’s Malta Becomes The Radeon HD 7990.
According to internal tests, this new product in terms of performance in the most popular computer games ahead of the GeForce GTX 690 from NVIDIA and is by far the most productive two-chip discrete graphics card for desktop PCs.
The model is based on a black printed circuit board under the bus PCI Express 3.0 x16, and equipped with a pair created by the 28-nm design rules Tahiti XT chip architecture Graphics Core Next (GCN). Each GPU sozherzhit 4.3 billion transistors, has 2048 stream processors, 128 texture units (TMU), 32 ROP units (ROP) and is available to 3072 MB of GDDR5 memory with 384-bit interface.
Graphics core frequency is 1000 MHz, and memory chips – 6000 MHz. Responsible for the removal of heat from above covered enclosure dual-slot cooler active type, the design of which there are two-piece aluminum radiator with multiple copper heat pipes blown three 92-mm fans with low noise. On the reverse side of the PCB is secured additional cooling plate.
The stated performance graphics card is 8,2 TFLOPS, while the TDP does not exceed 375 watts. For additional power supply provides two special 8-pin connector. The back panel has four Mini DisplayPort output port and one DVI. The accelerator is compatible with DirectX 11.1 and supports technologies such as AMD CrossFire and AMD Eyefinity.
For the U.S. market suggested retail price of Radeon HD 7990 is set at $ 1,000.
AMD has promised that the new Radeon HD 7990 graphics card with a capacity of 8,2 TFLPOS absolutely all the top modern games can be run with a resolution of 4K. Moreover, eight games go straight complete with graphics for each buyer: BioShock Infinite, Tomb Raider, Crysis 3, Far Cry 3, Far Cry 3: Blood Dragon, Hitman: Absolution, Sleeping Dogs and Deus Ex: Human Revolution.
On the board Radeon HD 7990 located two accelerators Tahiti GPU at 4.3 billion transistors. Each of them is surrounded by a 3 GB of GDDR5 memory and is connected to the switch PLX Technology PEX 8747. Each GPU – 2048 of processors Stream, 128 texture units, 32 ROP and 384-bit bus.
Unlike other cards, there is no resources are locked into marketing purposes. Everything is working. Even the GPU clock speed is set at 950 MHz, slightly higher than the Radeon HD 7970, and it goes up to 1 GHz. Memory clock speed is set at 1.5 GHz, as in an overclocked Radeon HD 7970 GHz Edition, while the standard Radeon HD 7970 frequency is 1.375 GHz.
Power consumption at maximum power is 375 watts in sleep mode – 20 watts.
The new flagship in a line of video cards AMD is positioned as a competitor to the recently introduced graphics card GeForce GTX 690 dual-GPU graphics card and the GeForce GTX TITAN. At the very least, all three have the same retail price of $ 999.
Subjective comparison test Radeon HD 7990 and GeForce GTX 690 shows mixed results with the advantage of GeForce GTX 690 in six of the eight tested games. But AMD clearly wins on the quiet operation.
