speed of 1.5 vs 1.7

[tomc70]

will I notice any measureable difference in performance in a T42?

You will have up to a 13% increase in clock speed for CPU intensive activities - a combination of the increase in speed and (I assume) the change from a Banias to a Dothan CPU. Will you notice it? Doubtful.

For $20, it's well worth the psychological boost!

(FWIW, I think I can tell the difference.)

If you're like me and spent a good amount of time encoding and doing other CPU-heavy tasks, you might see a marginal improvement in the time it takes, but for most tasks, I would doubt it.

You should definitely notice better performance if you go from a 1.5 Banias to a 1.7 Dothan.
The Banias has 1MB L2-Cache, whereas the Dothan has 2MB L2-Cache, quite an important improvement!

In real world usage, unless you really tax the system with resource intensive work, then you will most likely see no difference. I've had the experience of moving up from one to another just as your question poses. And even as hard as I push a machine, with truly demanding apps, the speed increase was disappointing to say the least. By virtue of the demands of my work I've upgraded to the fastest ThinkPad workstation each time a new processor is released for the last decade. There has been very few times when I've thought "wow that's fast". And I fully load my ThinkPads with max ram, fastest hard drives (now SSD's) and every available option. I throw battery life to the wind in exchange for speed. The most impressive speed increase I have ever experienced came from installing an SLC MemoRight GT SSD which cost a whopping $3,000 USD. For that price it _better_ be fast..ha..ha..ha

I used to tell people they wouldn't notice the difference in such changes unless they ran certain CPU-intensive applications like photoshop or compilers, but now I tend to suggest that they will likely notice a significant improvement. The difference relates to the more complicated WEB pages that are being used on many sites (like eBay and Amazon) All that "stuff" (banners, flashing junk, etv.) tends to be poorly written and uses your CPU cycles.

That's a very good point!

I do not tend to notice it much due to the fact that I have maxed out the memory and other resources in the various ThinkPads I have, which of course masks the point that you have brought up. And yet that said, I still notice a bit of slowdown.

Your contribution is just another reason that I truly enjoy this forum, there is so much for all of us to learn from each other as we work as a team.

Thanks for your informative post, richk!
