Intel 64bit's look better...
I went on Newegg, and found some 64bit Intel Processors. A Pentium D had 2x2MB cache and a 3.73 Ghz speed. AMD's were at 2.6 and 2x1 with the FX60. Is the AMD still better?
Ofcourse, any Pentium or Pentium D is still a Pentium 4 at Heart even if it might have 64-bit support> But they are not Native supporters of 64-bit environment thats why Intel is'nt a very good advocate of this technology.
In Conclution Yes, AMD is better in all aspects of all Pentium 4 and Pentium D and Pentium EE Processers. Until the 32 bit Yonah and Conroe Does'nt come out all Crowns Still Officially Belong to AMD64s
Those numbers are just the tip of the iceberg, you need to compare the two architectures as a whole.
Clock for clock, the K8 architecture can perform more work than Netburst so you can't compare the operating frequencies.
Dual core K8 have an internal link allowing them to directly communicate together, Netburst dual cores have to go through the Northbridge in order to pass data around.
Just look at benchmarks and draw your own conclusions.
I think you need to be careful. First of all, there is no Pentium D that goes up to 3.73GHz. Only the Pentium Extreme Edition 965 is 3.73GHz and as far as I know it isn't available yet. At least Newegg doesn't list it:
Newegg lumped the single core Pentium 4 Extreme Editions with the dual core Pentium Extreme Editions, so the 3.73GHz you see there is a 2MB single core.
Overall, the 3.73GHz 965EE and the 2.6GHz FX60 are pretty close in performance with the FX60 being generally a bit better. It depends on what you plan on doing though. When it comes to 64-bit support, the FX60 should pull ahead, because as other people have mentioned, Intel's current 64-bit implementation isn't optimal. If you are overclocking, the 965EE is a good option since it has great clocking room. In terms of power consumption, it used to be a big problem for the Netburst architecture of the Pentiums, but with the new C1 stepping on the 65nm process, the 965EE still consumes more power than the FX60, but not significantly.
