AMD Vs. Intel: Processor cores

[Shimi]

I've never quite understood how AMD can smash in so many cores and threads and still perform worse than many high end Intel CPUs.

My mate has a 4 core 8 threads AMD CPU. with around 3.2-3.5GHZ clockspeed (Can't remember). Performing way worse than my Intel 4 core 8 threads I7 6700k.
I'm talking about MASSIVE fps differences. In games where I can get 200fps on max settings he can get like 80 on the lowest.

Do you have the same graphics cards? Also as you are hinting, cores aren't everything! I'll find some more research on it...

Also, if you compare two CPUs with the same core/thread count (as you are) Intel will always be better I presume

Core's and clock speeds aren't everything when determining the power of a processor. It's about the IPC, Instructions Per Cycle. Basically how much things can it push per round of computing. It's the same reason why quad core computers 8 years ago are weaker than what they are now, it's about the quality of the cores.

Intel pushed single thread performance over multi-core processors, and AMD did the opposite 5-7 years ago. Now Intel has the single thread and multi core performance to match.

It should also be noted if you're talking about AM3+ (because nobody has AM4 stocked quite yet) then you should remember it's nickname ; faildozer.

AM3+ CPUs had shared cores, IPC easily beaten by intel, and generated lots of heat for not much more performance than i3's.

While they honestly were actually pretty good at multithreaded tasks, that's what games usually don't need. They need single core performance. With intel's high IPC and overclock potential, it's obvious who the winner was.

That cpu your friend has, is most likely a very old cpu built on a 32nm process, where as skylake is built on a 14nm process. AMD's new Ryzen processors are also built on 14nm, so they should be more compairable to skylake/kaby lake in terms of the performance per ghz.

Basically, your friend has an ancient CPU and you have a recent, powerful one. It's not an even comparison as CPUs get better every year by more than you could possibly imagine. Joyous trivia...

Maybe during periods in which competition is present, but only now will people see a decent difference between Sandy Bridge and newer tech provided the CPU is the only thing they're worried about.

I know Intel is lazy, but 5% every year is okay for me 😛

Thanks everyone for your answers.
I forgot to check on the post, but I think I got what I wanted.
