Just before the expected launch of the Radeon HD 7950 , AMD's second graphics card based on the GCN architecture , there are increasing information and pictures.Screenshots confirming the already suspected specifications , and in addition also have been seen AMD's reference design. First round out the unofficial benchmarks of data.
After the Turkish counterpart of the first DonanimHaber circulated prior to 31st January 2012 for the launch of the HD 7950 confirmed that they now deliver a GPU-Z screenshot , which will show the specification of an HD 7950th The data with 1792 shaders ( ALUs ), 32 ROPs, the 384-bit memory interface, and the 3 GB of GDDR5 memory correspond with previous expectations.
The slimmed-down "Tahiti" GPU clocked at 880 MHz and therefore the memory at 1,250 MHz (effective 5000 MHz), but it is obviously an overclocked version, because the default GPU frequency is 800 MHz. One of the first comparisons of the HD 7950 with 880 MHz compared to previous models dare to colleagues as well.
Other benchmarks are from the Asian region and were loud screenshot with a HD 7950 with the alleged default clock of 800 MHz achieved, except for the GPU clock from the specifications are identical to the above. The results are in
3DMark11 with a HD 7970, an HD 6970 and a GeForce GTX 570 from Nvidia compared, it appears that the HD 7950 and GTX 570 as expected on HD ranks 6970th The HD 7970 is obviously out of reach when overclocking the HD 7950 to 1030 MHz (GPU) and 1,400 MHz (memory) but it comes dangerously close to its bigger brother.
Already a few days ago appeared photos and specifications of the first HD 7950 from Sapphire on own design. The card with the full product name "Sapphire HD7950 3G GDDR5 PCI-E HDMI / DVI-I / OC DP DUAL MINI VERSION" has a large cooler with five heatpipes and at least two axial fans. The GPU is from the factory with 900 MHz and are thus significantly higher than the other places mentioned reference clock of 800 MHz.
Lastly, it is alleged the OBR hardware reference design of a HD 7950 with 3 GB. Accordingly, a centrally placed fan is provided - this would be more unusual than the AMD design in the class, as the smaller models are based always on the flagship. The fake danger is not small. Nonetheless, the connections should comply with one DVI, one HDMI and two mini-DisplayPort to those of the Sapphire model.
In the standard clock for the GPU, the rumor mill is not in agreement, because here is the GPU clock again indicated at 880 MHz. In the memory there is apparently no doubt that this will work with 1,250 MHz. The PCB of the HD 7950 is supposedly completely different than the HD 7970 to be designed. According to OBR is a hardware unlock disabled shader units to the number of HD 7970 (2.048 ALUs) with a probability of 99.9 percent is not possible.
