Which processor is faster?

[boris]

I have a T42 with a:

Q442A136 SL7GL
RH80536 1500/2M processor

I think that is 1.5 Ghz.

I also have a

RH80535 1600/1M processor

that I know is a 1.6 GHz from a T41.

Which is faster? I would think the 1.6, but I am sure that the 2M means something in comparison to the 1M.

Any opinions?

It depends on what you are doing. Of course, 1.6 > 1.5, but a cpu-intensive program with code larger than 1 megabyte would be faster on the 1.5/2M.

I would stick to the 1.5 just because it can be undervolted more.

[RealBlackStuff]

The 1M and 2M are the internal caches on the CPU in MegaBytes.
The better CPU is the one with the larger cache, as aaa mentioned.

[Quicklite]

I think clock per clock 2mb chips are 5-10 percent faster anyway, but in realtime, the difference would be minimal.

[underclocker]

I say it will be close, but for some reason, 1.6's have always felt faster than 1.5's to me, even Dothan 1.5's. I think clock speed wins out for making XP feel fast.

Why not benchmark the two? The Dothan might excel at some tests, but I think the Banias would win out overall. Try this free utility --> http://www.cpuid.com/pcwizard.php
