[VR-Zone] 2-way and 3-way AMD CrossFire and NVIDIA SLI scaling on Intel Sandy Bridge

post #1 of 9
Thread Starter 
Quote:
While Intel Sandy Bridge-MS does not pledge inherent multi-GPU support, it is a waste to ignore its performance potential - particularly for multi-GPU systems. What the Intel Sandy Bridge microarchitecture offers for multi-GPU configurations, is higher IPC that alleviates processor bottlenecks which have plagued multi-GPU systems for so long.

Would of liked to see SB against other platforms with SLI/CF. They're kind of just comparing Crossfire vs SLI scaling, SB doesn't really matter because it's performance isn't contrasted against anything else.

Nvidia games and benchmarks were nvidia dominates. Also 3 cards are not scaling well at all with SB.

Also, who play those games? They need to test more popular games.

This. Without other platforms to compare against this review is a waste of time IMO.

Maybe you missed this. Heaven2.1 is prefect example. After you factor in the overclock there is not that much difference.

LGA 1155 has native support for 16 PCI Express 2.0 lanes across a maximum of just two devices. A single graphics card would operate in x16 mode, but on a two-card AMD CrossFire or NVIDIA SLI configuration, each graphics card operates at only x8. In comparison, the LGA 1366 platform provides a total of 36 PCI Express 2.0 lanes, easily accomodating four graphics cards in a x8/x8/x8/x8 configuration.
