PCIe 2.0 vs PCIe 3.0 on a Configuration 2-Way SLI GeForce GTX Titan
Since the appearance of the first video card specification 3.0 compliant pci express (PCIe) back in December 2011 (Radeon HD 7000 Series), have come to light many tests measuring the graphics performance and GPU accelerated computing by testing with the two most recent specifications of the pcie bus and subsequent testing video cards based on GPU Nvidia geforce GTX 680 and even in dual GPU solution GeForce GTX 690 .
The results of all previous tests cast a blunt reality: none of these products was sufficiently powerful to be noted the benefits of PCI Express 3.0 over its predecessor PCI Express 2.0, so we had a virtual tie in the performance of both versions of PCI Express.
The Anandtech conducted a comparative facing both new PCI Express bus specifications (3.0 vs. 2.0), this time using two powerful video cards based on GPU Nvidia GeForce GTX Titan configured in mode 2-Way sli 16x/16x; installed on a PC Origin Genesis (Intel Core i7-3970X OC 4.9GHz + Intel motherboard DX79SR + 16GB DDR3-1866).
Here the results:
A 2560 Ã— 1440 PCI Express 2.0 still manages to not be far behind PCI Express 3.0, but increasing the demand graph to a triple monitor setup (5760 Ã— 1200) is finally shows that PCI Express 3.0 gets overcome by up to 7.06% for PCI Express 2.0.
From the results we can conclude that PCI Express 2.0 would continue to be sufficient for current GPUs for some time (keeping to the games), at least until they make their appearance GPUs with more than double the graphics power of the GeForce GTX Titan and popularize the use of graphics resolutions that exceed to 1080P.
