Eyefinity 2.0 ushers in the new era of 3D into the Eyefinity market. With the help of HDMI 1.4a and DP 1.2 the 7950 supports 3D in Eyefinity as well as custom resolutions. This is truly the next level in Desktop-based gaming.
AMDs’ Powertune Technology helps to unlock the true potential of a card through coming closer to the maximum board power. Logically, more power through the card returns better overall performance.
Zerocore is the balancing act of Powertune. While Powertune draws more power to the card for better performance, Zerocore minimizes the amount of power the card draws at idle (as low as 3w from the 24w 6xxx series used). This means better power bills and less stress on the card during idle.
PCIe 2.0 vs PCIe 3.0
ATIs’ release of 7 series GPUs brings another milestone to picture: PCIe 3.0. PCIe 3.0 is an upgrade from PCIe 2.0 in GT/s (Gigatransfers per second, referring to the number of operations transferring data per second). PCIe 2.0 topped out at 5GT/s while PCIe 3.0 tops out at 8GT/s. PCIe 3.0 is also an upgrade from the origianal due to the type of encoding (from 8b/10b to 120b/130b. This means that the amount of overhead has dropped from 20% to 1.5% and a memory bandwidth speed upgrade of 100%. During our initial testing phase we put this card in a PCIe 2.0 port on an Asus F1A75m-Pro board with an A8-3870K. Comparing our results between that setup and our final test setup (PCIe 3.0 with i7-3820) we saw up to a 60% increase in benchmark tests. While this card will run in a mid-level setup it is obviously meant for the enthusiast setup. It is then surprising that AMD, being with ATI, is not currently supporting PCIe 3.0 and has announced no plans to do so with upcoming chipsets. However vendors may choose to add PCIe 3.0 to their upcoming motherboards because of the dependence on PCIe 3.0 for enthusiast-level cards.
