Dothan Reviews and Benchmarks

Intel's Dothan Makes Its Late Debut - THG

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.

looks to me to be a fairly good upgrade...but i don't know how much one of these notebooks coupled with one of these dothans would run

performance increased but it doesn't look like that 2mb cache did too much, more of the processor speed...

its a step up from bianas since u can run a dothan at 2ghz and have the same battery life as the 1.7 bianas.

upgrade for intel


now imagine bianas on a 90 nm process...only imagine how much battery life would improve...

I think its not significant even if Intel put Banias at 90nm, platform is more important, so for battery life next generation Sonoma platform should do good things. Additional performance Dothan gives justifies the possible battery life increase by just shrinking Banias to 90nm. Like how do we know if Banias were put at 2.0GHz, it would slow its performance increase per clock scaling? That's what probably the large L2 cache comes here. And the extra 5% from doubling the cache which some people don't think it matters but without it performance advantage of Dothan may be around 15% or less depending on how well Dothan scales in performance increase per clock increase. And 5% is a lot to people considering they think Prescott can't compete with Northwood C at all which in reality its less than 5%. I think Dothan is very good. I knew when Tomshardware released the Celeron M review, I knew Dothan won't get more performance from the L2 as much as people think. Something like Athlons did with the Barton core. As for the price Dothan would cost same as Banias at 1.7GHz when Intel introduces it later at 1.7GHz.

PS People are never satisfied

Increased cache on a mobile processor typically reduce overall power consumption of the laptop. The extra 1MB of cache may add a few watts extra to the CPU power dissipation, but will also reduce the amount of cache misses and consequent need to access RAM, which also costs power.

Believe it or not they overclocked Dothan to 2.40 GHz without any stability problems. The results are fairly impressive.

From the Conclusion (via Babelfish):

Who says very weak heating says tentative overclocking. Although the modifications shown here are not very advisable, they enable us to note that, as opposed to what one could believe, the core Dothan has reserve in term of frequency. A overclocking with 2.4 GHz with a temperature in full-load of 30°C gives performances comparable with Athlon 64 3400+ or one Pentium 4 3.4 Ghz, CPUs top-of-the-range current! What to make dream considerable power-users with impressive overclockings. The next stage in term of evolution will be now Dothan 533, coupled with the chipset Alviso. Equipped with a frequency of buses which will pass from 100 MHz (400 QDR) to 133 MHz (533 QDR), this new Dothan will be shouldered by a chipset derived from Grantsdale which supports the DDR400 on two channels. The performances should once again be astonishing

Those are very impressive benchmarks - nice to know that intel has at least one chip that can match a64 in a clock for clock basis.

PC makers unveil Dothan notebooks

At the launch of Dothan today, Dell announced the immediate availability of selected labtops based on Intel?s new chip. These models include the Latitude D800, Dell Precision mobile workstation M60 and Inspiron 8600.

Besides Dell, five other PC manufacturers--Hewlett-Packard, Fujitsu, NEC, Acer and IBM--will also introduce Dothan-based notebooks within the next two months. Toshiba said in a subsequent statement it will also incorporate the new Dothan chips into its Tecra M2 series of business notebooks.

Is the performance/power consumption difference (Is there any?) between dothan and banias worth the wait for the dothan notebooks to come out??

 

[Accord99]

Dothan consumes less power at full load (TDP of 21w versus 24.5W), but a bit more at idle (2-3W versus 1-2W) as compared to Banias. It's not too significant, maybe a few minutes either way.

I guess i'll just get a laptop right now. I was thinking of getting a T42, but it's just too expensive for me. I spec'd out a Toshiba Tecra M2 with the Pentium M 1.7Ghz Banias, with 1024MB Ram (only $50 more from the standard 512MB!!), DVD burner and 60GB 7200rpm HDD for $2400.

There's not much difference. Gaming and battery tests seem to be quite close (neglible differences). Dothan seems to have a small advantage in audio/video encoding and rendering. The gains you'll see will be more from getting a chip with a higher clockspeed if you go with a 1.8GHz or 2.0GHz. The 1.7GHz Dothan and Banias are closely matched.

With the price cuts, both the 1.7GHz Dothan and 1.7GHz Banias are good buys.

I think this thread deserves a bump up to the top, just because it contains such valuable information.

I'm getting a laptop with those same specs and a 9700 card to boot, for almost $1000 less. At least go look at powernotebooks M 5:6 Force (way better). I'm building my own though.

Dothan is awesome, now all we need is MXM and AXIOM to get here *sigh* wish it was here now cause I gota buy soon
