As you know, it is the graphics subsystem that determines the performance of the entire platform equipped with pretty high-speed processors in the majority of contemporary games. Therefore, we do our best to make sure that the graphics card is not loaded too heavily during the test session: we select the most CPU-dependent tests and all tests are performed without antialiasing and in far not the highest screen resolutions. In other words, obtained results allow us to analyze not that much the fps rate that can be achieved in systems equipped with contemporary graphics accelerators, but rather how well contemporary processors can cope with gaming workload. Therefore, the results help us determine how the tested CPUs will behave in the nearest future, when new faster graphics card models will be widely available.
Frankly speaking, the results of flagship processors are very close to one another in the majority of contemporary games. The thing is that their performance is more than enough for the needs of existing gaming engines and the system performance is almost always restricted by the potential of the graphics sub-system.
Nevertheless, the diagrams show that the LGA 1155 platform is slightly ahead. The explanation of this phenomenon is plain and simple: games require low memory latency and LGA 2011 processors are often inferior to their LGA 1155 counterparts in this aspect. Therefore, unless PCI Express 3.0 support and the ability to build CrossfireX and SLI configurations are critical for your specific situation, the most expensive platform won’t be the best choice for gaming.
Besides, LGA 1155 processors also overclock to higher frequencies that is why Core i7-2700K strengthens its leadership in gaming tests even more.
In addition to our gaming tests we would also like to offer you the results of the Futuremark 3DMark11 benchmark (Performance profile):
3DMark11 is an extremely politically correct test. Although LGA 2011 processors in general and Core i7-3820 CPU in particular didn’t shine in real games, this synthetic benchmark ranks all platforms according to their overall price. All this clearly indicates that Futuremark programmers did their best to ensure high-quality multi-threading support, which doesn’t occur even in the latest computer games these days.
So, judging by 3DMark11 results, the quad-core LGA 2011 processor looks definitely better than its LGA 1155 relatives. The same is true also in overclocked mode: 200 MHz advantage of the Core i7-2700K doesn’t help it to become an indisputable leader in this mode.
