Other Integral Features of Contemporary Dual-Core Processors

Here we decided to offer you two additional diagrams that may be very interesting. First, it is the diagram that shows the connection between performance and power consumption:

I believe no comments are necessary here. The diagram speaks for itself: new Intel CPUs on 45nm cores have set new power efficiency standards, which will be very hard for other processor to reach. However, even older Intel processors on Core micro-architecture based on 65nm cores look not too bad here. This way, competitors from AMD will be less preferable for quiet performance systems, at least according to common sense.

Second, we put together a diagram showing the performance to frequency ratio that should reveal how efficient micro-architectures of different processors actually are.

The diagram shows very well that CPUs with Core micro-architecture can process more instructions per clock cycle than K8 processors. That is why Athlon 64 X2 should work at about 20% higher frequency in order to catch up with Core 2 Dup E4000 or Pentium E2000 performance.

And in order to compete against Wolfdale, AMD K8 processors should run at 40% faster frequency, which is simply impossible today. That is why the today’s Athlon 64 X2 simply cannot compete against new dual-core Core 2 Duo E8000 processors at all.
