In general, the more Hz the better the performance. But not always. MIPS is more meaningful because it measures actual instructions carried out (million instructions per second). Depending on the CPU, an instruction may take several cycles.
PassMark Software - CPU Benchmark Charts uses "passmarks" to measure CPU performance. I think is perhaps as valid as anything else I've seen.
E5630 @ 2.53GHz is 4991 passmarks, listed at $558
E5345 @ 2.33GHz is 2710 passmarks, listed at $196
So by both measures the first host will likely perform better. It's also a more expensive CPU, and that's an indication that it's likely better.

For some reason 8.1 Mandrake Linux seems much slower than Windows 2000 with my cable modem. DSL reports test says they conferable speed with Windows2 though.
This is consistant slow with both of my boxes, at the same time. Linux used to be faster, but not with Mandrake. Any way to fix this? (17 Replies)
