Dothan vs Banias...actual performance difference?

[tseeee]

most people now are getting dothan. I understand that one is 2mb cache and the other is 1...but how and when do you usually see the difference?

[stgreek]

Usually (basically in desktop use) you don't. If you are compiling code the extra cache speeds the calculations significantly, but IMO does not justify the upgrade by itself.

Agreed. Benchmarks have shown that there are no major speed increases beyond the clockrate boost in general usage. But only Dothan will be getting past 2Ghz.

But does Dothan generate noticeably less heat than Banias at the same clock speed? This may be an important factor in a portable computer...

Not at the same (low) clock speed, but at speeds >2ghz Banias would generate unacceptable heat / require more power, which is one of the reason that Banias won't be available in higher speeds

i THINK it was discovered that dothan was running faster than expected..
and at a lower power consumption..?!

can anyone verify that..?

Quote from Toms Hardware:

"Conclusion

In a direct comparison between the old Pentium M 1.7 GHz and the new Dothan with 2.0 GHz, the newcomer clearly manages to gain the upper hand. In some of the benchmarks, the mobile CPU produced with 90-nm technology is up to 22% faster. Even if you only consider the difference in clock speed between the two CPUs, Dothan still offers a 5% advantage.

The results of the battery life benchmarks show the benefits of 90-nm process technology. The two test systems were identical, except for the CPUs, and gave nearly the same results.

Intel's newcomer can accommodate business and gaming notebooks, as the Winbook W gaming benchmarks clearly prove. At the same time, however, a Dothan CPU doesn't offer any advantage over its Banias predecessor with regard to gaming performance. "

Extremely informative article over at Anandtech:

Dothan is a bit faster than Banias and is on par with/outscores an equally clocked AMD Athlon64.

Quote from Anandtech

Dothan, as an update to Banias, leverages Intel's 90nm process and some architecture tweaks to not stun us, but to keep us happy with the Pentium M platform. At 2.0GHz, the Pentium M 755 is easily the best chip that money can buy for a notebook. Clock for clock, it's faster and uses less power than Banias - there's really no reason not to like it.

If you're using your notebook for office applications and even for content creation applications, there's no beating the new Pentium M. Even developers will find short compile times, competitive with that of a similarly clocked Athlon 64, possible with the Pentium M at lower power usage as well.

[BillMorrow]

in short, its much better/faster than banias..

Just got my 2373KXU weeks ago. Very first thing I noticed is how fast my software was installing compared to my R50. No doubt it is faster from just using it. Not twice as fast but much faster so that you would notice if you had used something to compare it to.
