Processor performance during gaming

post #1 of 4
Thread Starter 
I have a few question when it comes to playing games and processor performance.

1) It is my understanding that anymore, gaming performance is more reliant on the GPU then the CPU. Is this true? If this is true, why would a gamer want to overclock their processor? Just for bragging rights?

2) What is the impact of a game on a 2 core processor versus 4 cores (or higher)? When it comes to gaming is a decent 2 core processor just as good as a 4 core? My understanding is that game will run single thread (I maybe completely off here) - or do we have games that run multiple thread. Would be nice to have some example that utilizes 4 cores.

Lower Res = CPU dependent
Higher Res = GPU dependent

1) because cpus can bottleneck gpus if they're not fast enough - what that does is prevent your gpu(s) from running at full speed - thus resulting in less performance

2) In many games that is the case, a two core cpu will be on par or nearly on par with a quad or hex core cpu. However newer games are demanding more cores some 3, some even 4. In those games the 2 core cpu will most likely bottleneck hard due to lack of physical cores and the result will be what happened in 1.

Single core cpus in gaming are pretty much dead, duo core cpus are hanging on by a thread (or lack there of), quad cores offer the best performance > cost currently, with hex and octa being in the next gen, sooner or later games will start wanting more than 4 threads.

BFBC2 will use 4 threads, GTX IV will use 4 threads... For a better idea use google, there are lists created back in 2008 you'll find more results than I can provide.

For some games, such as grand theft auto 4 and BFBC2 (not sure about this one) require a very good CPU, as for example, in GTA4 the map is so huge that your computer has to render everything.
