FS: 1.6GHz/SL7EG Dothan CPUs

[BobA]

I have three of them pulled from working systems - $15 each shipped. $38 for all three.

These are good upgrades to older systems running 1.3Ghz or 1.4GHz CPUs.

Just wonders if this will make any improvement to same speed Banias ( I have a old T40p with 1.6 Banias ).

It wouldn't be worth it in my opinion. Even going from a 1.5GHz to a 1.6GHz is marginal -- again my opinion.

The change from 1.5 to 1.6 is definitely marginal, but the change from Banias to Dothan IMHO is definitely not. You have PM.

If your old T40p has heat problems, then the Dothan may help but there will be no significant difference in performance from the extra 1Mb L2 cache.

Two pending sales - one left.

One left ..

So how much of a "+" do you need to see an difference between the banias and Dothan (heat issues aside)?

I have an R51 with a 1.6 Banias. I always thought the even swap was still an upgrade.

So do I need to go to 1.7, 1.8...? When would you notice the difference?

There are probably other more important bottlenecks in your system, like RAM and hard drive speed.

[dwilsonfl]

well let's assume those are maxed out. 7200 RPM HD, 2 GIG RAM

now, how much difference in swapping in a Dothan do you need to have in order to notice the change in everyday computing tasks?

If you assume all that, then you only have one thing left that you can do before you have to buy a different machine! Add the Dothan processor..... I can't really tell you that I can tell a lot of variation in .1, .2 or .3Ghz of CPU speed, but I'd bet that doubling cache size from 1 to 2Mb will be fairly significant. Probably more so than say upping from a 1.6 Banias to a 1.7 Banias or even a 1.6 Dothan to a 1.8 Dothan. You are just upping the speed that the processor does work that's handed to it vs. doubling the chances that the CPU has the data on hand instead of having to go out to the bus and get it. As you probably know; on most routine tasks waiting for a CPU to crunch data is rarely the hold up, it's more typically that the CPU is waiting around for data to be delivered to it via the bus from a far slower storage medium which causes the delay.

I wouldn't bother to upgrade unless you can get a 2.0 or 2.1GHz.

I have done 1.3 - 1.7GHz, 1.7-2.0GHz, and 1.7 to 2.1 GHz. Each was noticeable - but not a huge difference.

[underclocker]

Don't underestimate the psychological boost!

[awolfe63]

I forgot.

My new business - for $10, I'll stencil X9800 on your processor.

[dwilsonfl]

Any power management benefits from going with a Dothan over a Banias or P4M?
