As usual, just before the official launch of the new Radeon HD 7990, AMD's local partners were given the available marketing materials with photos, specifications and performance benchmark. Although the same should not spread on, such information is difficult to hide, and they often leaked to the public.
On photos that someone photographed from the monitor can see that AMD is not particularly reduced opportunities HD 7970 GPU to a new card with two of these GPUs have reduced consumption. GPU's on the HD 7990 have a clock of 1,000 MHz compared to 1,050 in HD 7970 GHz Edition. There really is not entirely clear whether a standard or so. Boost speeds and maximum speeds that chip is achieved when the automatic overclock. Standard GPU on older card is in fact 1,000 MHz and 1,050 MHz Boost clock. Therefore, if they are mentioned Boost clock, standard GPU's on the HD 7990 is actually 950 MHz
Confusing at first glance, and theoretical performance. According to the table would suggest the HD 7990 has an unusually large texture filtrate compared to 7970th This is not true because if you multiply the clock speed of the chip with the number of units for texturing, it turns out that the value of 7970 GHz Edition was calculated incorrectly (it should be 134.4 GT / s). Same thing with pixel filtration which should amount to 33.6, not 29.6 gig pixel per second.
Probably the most interesting in the story is the performance chart showing the results of the tests 3DMark first Strike Extreme. This new two-headed Radeon overrides to Nvidia's Titanium, is currently the most powerful card based on a single GPU, and GeForce GTX 690, which also has two GPUs. The official presentation of the Radeon HD 7990 is being developed under the code name Malta has been confirmed for Wednesday.
