AMD CPU Efficiency Compared

The other problem with the article is that the tests used generally did not scale to 4 cores. The raw performance data between the dual and quads did not give the quad core its full due.

The other problem is that the Phenom is not designed to be a low power solution for geneal computing tasks. Which is what they sort of tested.

It can be low power for heavy duty tasks.

Until AMD releases a Dual-Core version of the Phenom might that qualify.

I also would have been very curious to see the 5000+ BE.
That tends to run quite cool with some oomph.

That may have done better on the charts.

Not to mention that they compared a P4 3GHz to a core 2 duo, which are SIGNIFICANTLY different architectures while the AMD cores are all basically the same architecture over just two generations of processes. I think that AMD's 60% reduction in power over the same architecture is fairly impressive.

I think they could have drawn another conclusion about the strength of the Athlon architecture vs the craptacular mArch of the P4, which was a mistake from Day 1, if we're going to be truthful. It was Intel saying all that mattered was GHz, not performance.

I really liked the power consumtion graphic. It was so pretty will those lines going mostly across, with the odd squigle up and down.
Then again, to be a valid cpu benchmark, you would expect to see the straight across part at the top wouldn't you?
It brings up a good point. Why do you not show cpu usage in your benchmarks?
It would certainly show floptimization by one company or the other.

I felt the % comparisons (400 to 60) were a bit unfair... mainly because Intel's Netburst CPUs were about the worst (i.e. most inefficient) CPUs ever made... and of course whatever Intel comes out with next (C2D) is going to be light years ahead of that.

of course intel is now 400% more efficient because they compared a Core 2 Duo with a Prescott (which if we all remember, would require a 500W PSU, and it's idle temp would be somewhere between 50 - 60 degrees) Now I`m no Intel/AMD fanboy but please... that comparison is flawed.

Bytch, Muk works for Tom's Hardware, that might explain why he's posting their work on their forum.

Yet another paid advertisement for intel.
