The AMD Radeon HD 7950 is the little brother of the HD 7970 and is also in the middle class make it unmistakably clear who currently holds the 3D crown. But it is worthwhile at all to buy the smaller version? Latest technology and compromised performance must be proven in the PC World Test only.
After the flagship Radeon HD 7970 AMD sent the reduced-power version of AMD Radeon HD 7950 into the race. The technology of the 7950er card hardly differs from the specifications of the 7970, since the new model uses the same 28-nanometer graphics chip. In the test, the AMD Radeon HD 7970 PC World has already explained the technique of highly complex graphics chips. AMD has just turned down the clock speed of the GPU from 925 MHz to 800 MHz.
But as in the 7970 it should be possible according to the manufacturer to overclock the card to over 1 GHz. Also located on the Tahiti-GPU slightly less shader units: 1792 instead of 2048th The remaining units of the cluster shader, texture and raster operations units remain the same. Just like the huge number of transistors - 4.3 billion.
The 384-bit wide memory interface controls as usual 3 gigabytes of GDDR5 video memory, which has a slightly lower clock factory of 1250 MHz (5000 MHz effective). The current techniques, which the manufacturer has introduced with the Radeon HD 7970, as AMD Eyefinity, HD3D, Power tune and zero power are still among the core functions of the smaller DirectX 11.1 graphics card. The connections for the issue have also remained the same: two mini-display ports, one HDMI and one DVI.
With the AMD Radeon 7950 PC WORLD leads a new test method and a new test platform: it forms the heart of the motherboard from Intel DX79SI. On the board operates a real performance monster: The 3.3-GHz processor Intel Core i7 Extreme Edition 3960X with six cores. The processor has four memory modules of the type G. Skill RipJawsZ with 4 GB capacity to the side, a total of 16 GB. The processor is a single memory channel DDR3-1066 module with the access times of 7-7-7-7-20. When the disk is 240GB SSD Kingston HyperX used.
