Intel Dothan Benchmarks

[asymal]

I'm looking for benchmarks for the new Intel Dothan CPU (in the 2.0GHz 'flavor'), with specific attention to the Intel Pentium4-M (3.2GHz). Now the primary focus is on CPU 'horsepower' rather than battery life and power saving features (I know the Dothan already 'wins' those hands down), as these laptops are focused towards developers (i.e. wannabe coders) and execs who think it is cool to have the biggest number (i.e. CPU speed- sadly they aren't bright enough to know that CPU speeds aren't apples to apples).

Thanks in advance for any help I can get!

I'm not aware of any Dothan benchmarks yet.

that the pentium III done right? Edit I don't see whats so impressive after reading the articles. An athlon mobile 2600/2800 xp 35W version, which runs ~2000Mhz will kill these. To little to late.

Zebo: you're forgetting about battery life.

AMD: 2 hours
Centrino: 6 hours+

 

[Zebo]

As I said the 35W Bartons use only 30% more power. 35W vs 24.5W. So your relation is more like 4 hours to 6 hours. And you're still slower @ 1.6Ghz. http://www.anandtech.com/printarticle.html?i=1800

 

[SickBeast]

Zebo: I highly doubt that. Do you have any links to a benchmark of an AMD laptop lasting 4 hours? I have yet to see one that is speced to last more than 2.

Also, do the AMD chips have the advanced speed throttling features of the Centrino? 35W vs. 24.5W is a huge difference BTW.

AMD has powernow which reduces the core to less than 1 volt and 600Mhz.. no data on wattage. The reviewers simply do not do enough work in the notebook arena. But 30% on just the processor is didly squat when all the other subsystems are the same. Monitor, video etc..

And this review proves it. http://www.anandtech.com/mobile/showdoc.html?i=1921&p=9

Don't forget you running a much higher performing A64, at much higher Mhz, and it's within 20% battery time. Certainly not this 300% difference you're eluding to.


Edit: and I forgot to mention the AMD system also has a radeon 9600 which not only uses more power than the centrino Dell Inspiron 8600 nvidia chip and performs about 20-100% better accross the board depending on bench.

On AC power the AMD may win the battle however, on battery the Centrino wins the war on power and speed. The AMD powernow is just underclocking the CPU. The A64 3000+ is reduced from 1.8Ghz (yes the mobile A64 3000 is rated at 1.8Ghz vs it's desktop mate who is at 2Ghz)to 800Mhz and is slow as a turtle crossing the road. Not to metion the battery life on the 2 A64 and 3 XP2500 machines I have tested are all less than 3 hours. Throw a game or DVD in and is drops significantly.

i'm not impressed
hehe

I don't read toms. His site is confusing and it very hard to keep track of multiple system configurations and cooresponding benches on multiple pages. Care to summerize.

That's what so great about hexus and anandtech and a few others thier printable verison..to say the least

Strange how the linked debates have spilled into this thread.

Thanks all for the responses; I had seen both the Tom's & x86 reviews/benchmarks, but unfortunately neither compare to the P4-M 3.2GHz chip (at a non-OC level).

I guess I'll just have to do them myself when I get my eval units in (should be tomorrow or Thursday). If there is any interest, let me know. I'll post up any results wanted here (please specify if there are any benchmarks you'd like to have run).

i'm interested in such a comparison. a divx benchmark would be nice

I say wait for more sources to make the final veredict.

By the way, to the person who said that no AMD chip can last over 4 hours ir battery, I invite you to work with my former baby, the compaq Presario 2100Z 2000+.... At low screen intensity and web browsing it was at about 4:10....... with a wimpy 56 kW/hr battery.

My M6805 can go to 3:05 also at screen intensity 5 (out of 11) doing basic stuff. At screen intensity3 it can go to 3:12..... and on battery it will kill most of the competition.... win2K with PowerNOW! working as expected. The infamous 800 MHz issue applies ONLY to XP. Yes, it will eat the battery quite faster, but for a quick frag is not bad at all.......

by the way offtopic. the way around that is to install the amd powernow software in compatibility mode for win 2000. i've got it working great with xp on my 6805.

From Zebo: "that the pentium III done right? Edit I don't see whats so impressive after reading the articles. An athlon mobile 2600/2800 xp 35W version, which runs ~2000Mhz will kill these. To little to late."

If we are comparing Pentium M's(ones used in Centrino), to AthlonXPs, then actually its the opposite. Since the Pentium 4 mobiles at say, 2.8GHz is comparable to AthlonXP mobile at 2800, and 1.7GHz Banias core can beat 2.6GHz Pentium 4 mobile, 2.0GHz with better performance per clock would kill the AthlonXPs at 2.0GHz. So I say 2.0GHz Dothan is like 3200+ AXP or 3.2GHz P4 mobile.

For battery life, its not that drastic between Centrinos and AXPs, but considering Centrinos are faster anyway, with most of the time slimmer form factor, Centrinos are much better for laptop users.


Most of you guys are fans of desktop PCs, and nothing other than desktops, your comments should be taken with a grain of salt, since its praising desktops and dissing laptops. I mean, most of you would get a 15 min battery life notebook that's 20% faster over 10+ hour laptop that's 15% slower.

The HP4600 and Compaq 2100 series AMD Barton mobiles get 4 hours of battery life. BTW Toms had an old review of a 1700+ mobile Tbred vs. a Pentium M around 1.5. While the 1700+ was a tad slower, I'm pretty sure that the newer Barton 2400+ through 2800+ chips are a decent amount faster than the well-established Banias 1.4 through 1.7 chips.
