What determines the speed/power of a processor? Tags: CPUs Quad Core Processors Power Last response: August 20, 2012 1:18 PM in CPUs Share huggles12 August 20, 2012 2:22:45 AM Hi there, just a quick question. What determines the speed/power of a processor? For example, everybody says intel are better. So what separates a an i5 3570k quad core at 3.4ghz from a Phenom II quad core at 3.4ghz? Shouldn't they be almost the same? How does the architecture make that much of an improvement? Hope this isn't a stupid question. Cheers.

I've looked on the intel and AMD website and I'm unable to find information to compare the IPC of each processor. huggles12 August 20, 2012 4:30:08 AM Okay, after some research I have found this wikipedia page on instructions per second https://en.wikipedia.org/wiki/Million_instructions_per_... There's a table that shows MIPS / Clock Cycles Per Second / Cores Per Die It has the i7 2600k at 9.43 AMD Phenon X4 940 Black Edition at 3.5 9.43 / 3.5 = 2.7 Does that mean the 2600k is 2.7 times faster? Or am I looking at the numbers too simplistically? whatismyproblem August 20, 2012 1:18:29 PM huggles12 said:Okay, after some research I have found this wikipedia page on instructions per second https://en.wikipedia.org/wiki/Million_instructions_per_...
