Mobile CPU Wars: Core 2 Duo vs. Core Duo

Application Performance using Winstone 2004
Winstone 2004 consists of two different benchmark suites; the Business Winstone test focuses on office applications, while the Multimedia Content Creation benchmark contains many audio/visual applications that are more CPU limited.
The Core 2 Duo performance advantage shrinks even further in Business Winstone 2004. Here we're looking at less than a 2% improvement clock-for-clock.
The situation is a little better for Core 2 Duo under MMCC Winstone 2004, but we're still only talking about a 3.4% increase in performance. The explanation for the relatively lackluster performance improvement is two-fold:
1) Core Duo is already a very good performer, and
2) Core 2 Duo is crippled by a 667MHz FSB
To a lesser extent, we're also more I/O bound on a notebook since 2.5" hard drives are significantly slower than their 3.5" desktop counterparts. The more I/O bound we are, the less we're going to be able to see differences between CPUs. That being said, notebook users aren't going to have 3.5" drives in their systems, so like it or not, this is where the performance stands.

Correct. Lots of the benchmarks show 10% advantage for Core 2 Duo over Core Duo. The only 10% advantage 4MB L2 over 2MB L2 is in a single app.

Video makes ALL the difference in the world.monsoon - Thursday, August 3, 2006 - link
I'm in the market for a mini PC to do video trancode, and I was considering the MEROM chip to compare to YONAH......in the end, given the right graphic card ( add ATI X1400 series or higher here ) with hardware embedded transcode features, i guess the YONAH fits my bill just right.
And i get to pay 100$ or 200$ less than the same computer with a MEROM which could not offer me better on the video side...
What do you think ?

I would get the best video you can get with the cash saved from getting the Memron.Tiamat - Thursday, August 3, 2006 - link
Whats the difference between the Intel Core Duo T2300E* and the Intel Core Duo T2300E?I see a difference in price, but not specs. The page in the article does not address the asterisk...

The asterisk means that the CPU lacks support for Intel Virtualization Technology (VT). I had the note on Page 3 but I forgot to include it on Page 2 :) Thanks for the heads up :)Take care,
