I really don't understand all the tech mumbo jumbo about console cpus and gpus, can't get my head around how the Xbox360 has a cpu which has 3 cores (whatever they are) which runs at 3.2ghz and the 720 possibly has 8 cores at 1.6ghz, More cores but half the speed, how is that better?! Can someone please explain it all to me but keep it simple, imagine you're explaining it to a simpleton! I've read the WiiU cpu topics on here but it all sounds like gibberish to me, "gtgjifdcgybjfr 1.4ghz cbftjjhgdfbh ram buffer deghjhfgbjffghamsandwich". It just doesn't make sense to me!?!

Clock speed should never be used to gauge processing power; some CPUs can process more instructions per second than others, some fall flat on complex code where others don't....there are a lot of factors that figure into the equation.

imagine consoles are apple trees, and you need to put apples in a wheelbarrel and wheel them to a box to dump them out.

360 was 3 fast guys with itty bitty wheel barrels that could hold 2 apples each.

720 is 8 Zangeifs that can wheel mountains of apples, but take twice as long to go from tree to dump box.

So how is that better then, it can do more but it's slower doing it!? Surely do more at the same speed or faster would be better?

Hows it better? You have eight mountains of apples arrive at the same time the 360 would deliver 12 apples.

I think what's confusing me is the fact the speed is 1.6ghz where as the 360's is 3.2ghz, I can't get my head around slower speed,even if it's doing more,is an improvement? It's obviously capable looking at the games shown for the ps4 which has a similar cpu (right?)but still seems weird and confusing to me.

Its a very simple concept. It doesnt matter how fast you are at making trips if you are so weak you can only carry one apple.

If 360 makees five trips in the same amount of time 720 makes 1, but can only deliver 1 apple each trip, but 720 can deliver 500 apples in 1 trip, 360 would need to be 500x faster than its current speed of 5x faster than 720 to keep up.

Google Mhz myth for further reading, but keep in mind its not going to be as simplified as youve requested.

Ah I see, ok that's cleared it up a tad for me. Cheers for that. Was actually suprised that you managed to keep it simpleton friendly for me,as I've read your other posts explaining tech and they've all gone way,waaay over my head lol, so cheers again 3Dude!
