Isn't he asking about the single cores?? While it's not really accurate to say which AMD processors are equal to Intel processors, you can give rough estimates. This is because there's a lot of different technology that each company uses. In terms or raw speed, the Opty 146 runs at 2.0 ghz. AMDs perform 9 instructions per cycle (IPC) and Intels perform 6 IPCs, so to do the math, just take the AMD speed and multiply by 1.5 to get the rough equivalent. Opty 2.0 ghz x 1.5 = 3.0 ghz. While this gives you the rough clock speed, you have to keep in mind that the Opty's have 1 mb of L2 cache, has a integrated memory controller, and doesn't have the traditional front side bus but has Hypertransport that runs at 1000mhz (2000 mhz effective) that all contribute to it's overall performance. The Pentium 4s have 1-2 mb of L2 cache and traditional front side bus with the memory controller located on the north bridge with the bus runninng at 800mhz.
sorry... I don't know why I was thinking 165... oh well...
Just to add to what everyone else said... AMD processors tend to be much better at single threaded applications like games, while Intel processors tend to be better at multithreaded applications like multitasking. (for single core cpus)
