Multithread/single games with AMD/Intel CPU's

post #1 of 4
Thread Starter 
I've seen this thrown around a couple times while people are discussing which processor to go for. Something about how most games only use one thread which puts Intel ahead, while some other applications utilize more, putting AMD in the lead.

Was wondering if someone could possibly give me an explanation for this.

Intel typically has higher IPC (instructions per clock). If you were to compare 1 core from a Haswell CPU at 4ghz, it would be a lot faster than a Vishera core at 4ghz. In games/programs that don't make use of a lot of cores, the Intel solution gives better performance. But from a value standpoint, the FX 8320 is an 8 core CPU from AMD and can be purchased for less than most core i5 quad core CPUs from Intel. This means even though the Intel is faster on each individual core since the AMD has 8 cores working for it- it will perform better in multithreaded situations. Hopefully that makes sense. If you throw out price though, the 4770K and 3930K (also 3960x/3970x) are still faster in multi-threaded scenarios clock for clock, but they cost significantly more.

Yeah, thats makes perfect sense.

But where does this get tossed into programs. Like how do you tell whether a program would use more than one core or not?

It just comes down to how the application is programmed and perhaps even the compiler. I don't know enough to elaborate, but generally older programs are single threaded while a lot of newer applications are multi threaded because nowadays there are a lot of people on dual cores or quad cores.
