Gaming Related Tests
These tests aren’t really GAME testing but are more synthetic gaming-related tests. For that reason these benchmarks are done using the GeForce GTX 285 graphics card installed and are meant to continue testing the x86 CPU performance of the benchmarked platforms.
A reliable and popular benchmark, 3DMark Vantage can provide a good insight into overall gaming performance of a system.
The CPU score in 3DMark Vantage takes a pretty big hit going from the 6-core parts to the quad-core i7-3820 and i7-2600K though that is mostly synthetic in nature. Real-world gaming sees very little differences between these kinds of processors though the SNB-E is coming in just ahead of the 2600K.
Valve Source Particle Simulation
Valve released this particle simulation test a while back for benchmarking platforms and CPUs.
Valve Source Map Compilation
More of a developer test than gamer test, this benchmark is indicative of how long it takes a system to compile a map.
Again we see something around a 5% advantage for the 3820 over the 2600K.
