    Why does this make you hate Intel? Yes, the P4 was probably a rather limited processor from the get-go, but other manufacturers have had limited-growth processors as well. It's cool to see a Pentium M beat out a P4 clocked more than 1gHz more than the P-M -- goes to show that CPU performance is far more than clockspeed. At any rate, Intel makes the P-M, and it's an excellent processor. The dual-core Yonah mobile processor is likely to be out the first half of 2006, though perhaps the official release announcement of this processor will cause a price-drop in the Pentium M line. I think NewEgg and ZipZoomFly have the least expensive P-M (1.7ghz) for somewhere aroudn $180-$210 -- a bit pricey for most folks' carputers.

    The P-M is an excellent choice for carputers though, mainly because of its very high performance, excellent mobo/component support, and extremely low power consumption given the clock speed. I think most P-Ms are designed to consume less than 25-30 watts, which is awesome considering >2ghz clock speeds.

    i just don't like the idea that a little mobile processor is beating out their most high priced desktop processor, for less money (3.8GHz P4 is quite pricey) using a fraction of the power, based mostly off of and older architecture. And limiting the performance benefits (until now) to just laptops

    I'm all about AMD personally

    Stuff like what........ they manage to produce a better chip for you to purchase. It's not like the p4 has only just come out.

    but the P M is a smaller die isnt it and it costs a lot more.

    YOu can get a highly tuned 2 litre engine that puts out more than a 3.5 litre but it will cost you more and takes more development.

    Pentium M CPUs are great little processors but they are simply not needed in a desktop where you have a nice big PSU and it keeps the cost down. Plus the PM took longer to develop. True, if they were all PM CPUs then due to economies of scale they would all cost less but it isnt that simple.

    So I've read through all the parts of the article, and Ido wonder about the validity of the results. Nowhere else in all the tests for P-M have I seen them do that well on Video tests. I can believe the gaming results, but not the video ones. And by the way, P-M architecture is not older than P-4, it is mostly different. Intel took two different approaches and one of them paid off more. If you are to say that Intel messed up with P4, then AMD messed up with latest Athlons, since they didn't get too far away from P4, especially in any of the encoding bench marks. Now if you want to see reaaaaalllyyyy old tech at work, check out C3!!
    I have found you an argument; I am not obliged to find you an understanding.

    Multi core is where processors are heading. They're approaching the mhz limit (the number of cycles in one second). With multicores, the processor can execute many instructions at the same time. I wouldn't be surprised if CPU's of the future are still 4-5ghz but with 32 cores and short pipelines. Sure it's still 4-5ghz but they can now execute 32 instructions per cycle which is the equivelant of who knows what...

    pentium m is reason enough to love intel...what a sweet little efficent processor with a large l2 cache....400 0r 533 fsb.....power efficient low voltage low heat low consuption.....I really like the pentium m.... the athalon xp-m is also pretty good....

    i was thinking about putting a Pentium M in my car...but the price of the processor is roughly 200...and the ITX mobo's that support Pentium M's are 300-400...thats really not worth it in the car. Im thinking about Celeron M for the car, or even an Athlon XP-M...however I have yet to find an ITX mobo for those 2 processors...but thats why i have to keep searching.

    to me it's worth it...especially when you consider the other problem areas that are adressed buy going pentium m....for example my whole motheboard/processor/chipset/video setup draws less power than just a p4 processor alone!...... the pentium m also wastes so little that it runs much cooler......

    It may only run at 1.6...but it is super quick when given a nice amount of ram......it feels faster than the p4 2.8 I took out.... while a p200 may work...it sucks when you run into a glitch & it takes what feels like 15 min to reboot....or god forbid your virus scan starts running in the background...crawl.... I don't think you need massive power in a carpc, but I do think you want something that is snappy & not frustratingly slow......

    honestly if I had it to do over I would go with a pentium m ultra low voltage processor 1.1.....these things are pretty quick still having the 400 fsb & large l2 cache....but run EXTREMELY cool & efficient....an awsome mobile processor.... I have one in my panasonic t2 laptop.....it runs so cool that there are no fans or even no vents at all on this laptop.....I can use it on my lap for hours......& it is pretty fast too.....

    one great way to go with a pentium m setup in a car is to start with a centrino laptop...I think they can be one of the best values for all around performance & compactness...... for around 500-700(ebay) you could get a pentium m laptop with a 1.6m 2mb L2 cache...on board low voltage efficient wireless mini pci built in..on board 32-64 mb video or more....usually with a dvd/cdrw that could be used in the install..sure there are challanges with a laptop..but They can make fine installs... if you can be creative enough to utilize the screen in your install it would work out to be a real great bang for the buck....
