The WoW Companion App is Retiring

My friend has a AMD 3,4 Ghz Phenom 2 965 Black edition Quad Core.
I have a Intel i5 2500 (not K) at 3,3 Ghz Quad Core also, but I think I have more cache memory.
Thing is, his AMD was cheaper (and I put together the system and parts for him)
But what is more beneficial Ghz or cache memory, since this feels kinda gimped and ripped in performance and price. :P

Neither and both. You can't compare two processors with simple numbers like that unless they are from same manufacture and generation. Cache has practical limit in games at somewhere around 2-4MB and more wont benefit you besides in scientific calculation. On the other hand raw clock speed will scale infinitely if all other variables are the same.
Just take a look at this, and you'll feel lot less ripped off and more like a winner:

Trolling should be.

I don't think Intel ghz are directly comparable with AMD ghz.
Anyway, this might help (though it doesn't seem to be the Black Edition):

Architecture, that's the whole difference, how the processor is built and chipset on the mobo it runs.

Simplfied: all modern processors are basically running several copies of the program (next few instructions) in parallel if there are free cores, and trying to guess where the program goes next, what memory it wants to access and so on. And if the guess was wrong, whole path and all resources spent for it are dropped to make room for the next guess. Guessing in advance is important because the processor is 100x times faster than cache memory, and cache is 100x faster than the RAM on motherboard which is again 100x faster than HDD. This is also what/why cache size matters. The further ahead the processor can guess right, the further ahead it gets in the program execution while it has to wait for the slow things (fetching things from RAM or HDD).
Anyway, Intel processors are far better at guessing ahead which is the major difference between the two manufacturers.

Ah right.....a different architecture....
Glad I got Intel then.
Makes me wonder what it is like to be a architect of CPU's.Last edited by mmoc13485c3c3f; 2012-11-22 at 05:12 PM.
