AMD needs to increase the core to clock performances of their cores, not the speed. If I overclocked a Bulldozer processor to 4.5 GHz it still might not even overcome an i7 2600K processor at stock.

That is sort of obvious. Both companies are always trying to improve CPU performance always.

However, both companies have to balance thousands/millions of design variables and market needs... so just IPC increase is not a clear objective either. If a better path prediction improves performance by 5% but costs 30w power budget... is it worth it?

Can anyone put into simple terms why AMD's clock for clock speed is so far behind Intel's in as simple an answer as possible?

The answers are not simple. wink.gif

It has to do with latency, chip architecture, and path prediction.....

Clock speed? Clock speed is pretty much irrelevant.

IPC is what matters or really IPS, but since bulldozer and sandy/ivy clock to pretty much the same it is really the IPC that differentiates the two. The reason bulldozer has such low IPC is probably because it is a brand new architecture and after it is refreshed it will become a bit more powerful. Or somthing like that.

IPS the most important reason and then it goes more complex. I have read an article for bulldozer in depth that explained what was the real reason but i cant remember from where. Latency is another good problem for the bad result

It's not the same thing. An AMD module does contain two actual execution cores. A hyperthreaded Intel CPU does not. Intel is allowed to say their approach works nearly as well as AMD's in handling multiple threads. They cannot, however, make false claims about the number of cores just because their HT technology does a good job of simulating multiple cores.

And yes, AMD will never beat Intel.
They've been farther behind than this, and come all the way back to beat Intel before. Before the K6 came out, they were selling the K5-133 (although they spuriously sold it as PR200) when Intel already had the P2-450. When Intel had the Pentium MMX 233, AMD's best was their 133 MHz 486. This is as big a lead as Intel's had in a while, but even now, AMD's nowhere near that far out of the game.

From reading articles and user submitted data on FX vs Phenom 2 IPC it seems that on average Phenom 2 is a good 20%+ faster so this 15% improvment people are stating still won't bring it up to Phenom 2 level.
