Performance in 3D Games

At the same time, there are some applications that use operating memory very actively, and therefore react immediately to any changes in its speed. These applications are 3D games.

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.

As we can see, gamers should really take memory speed into consideration. Of course, the situation is different in different games, but all in all one 266-MHz increment increase in the memory frequency produces about 2% gain in fps rate in nominal mode and about 3-4% in a system with an overclocked processor. Therefore, choosing the right memory for a gaming computer should be taken seriously enough. Slow DDR3 SDRAM modules may turn into a system bottleneck that will prevent the processor and graphics card from unveiling their true potential. Especially, since there are some games (in our case it is F1 2010), where you can gain a fps or two by simply playing around with memory timings. Not to mention a significant performance boost resulting from the increase in the memory frequency.
