    So is Pentium M just a bunch of failed Pentium processors that didn't fare well in the assembly line? Sort of like Celeron... cough cough.

    • No, it's a "new" (sorta) architecture apparently based on the Pentium III's architecture. It lacks some of the more advanced features of the P4 and even Celeron lines but it's lower power and will actually beat a Pentium 4 clock for clock in some applications.

If I start my laptop up without ac power then it will remain on 500Mhz no matter what, and it will stay on 700Mhz if I booted the computer with ac power. The speedstep options in the kernel specifically state that this version is not supported.

      I've been using my Fujitsu Lifebook P5000 1GHz P-M for a few months now, and I have to say I don't really notice the performance difference when it clocks down. It's still perfectly useable. The only time I really notice it is when I'm compiling or something, and even then it's pretty fricking fast IMO. People are spoiled by fast CPUs nowadays, consarnit.

        Yes, yes, procs are very fast these days, and all these young whippursnappurs are impatient young wags. However, wouldn't you be pissed off if you shelled out several hundred dollars extra for a fast proc that always runs at half speed?

    • That's totally bogus.

      If you are running a modern, ACPI-enabled OS, processor speed is fully controllable by the OS. My Pentium M sits at 600 MHz all the time, unless I need it, and then it throttles up to 1700 MHz as needed. My guess is that you are running Windows, since Linux uses the highest clock speed unless you install a throttling daemon (I use speedfreqd.)

      I do know, however, that the Pentium 4-M throttles down a ton, because its power management features are less efficient and the battery life would be less than an hour. As it is, most only get 1 to 2 hours.

      What OS are you running, anyway?

    • On my Dell 600m laptop, it doesn't permanently clock down, but instead adjusts the clock speed down until you're using an application, upon which it'll clock up to maximum speed. Pentium M chips have multiple behaviours depending on what you set it to do.

      And talk about dependable... I've taken it apart about 5 times, once to paint the exterior with my own designs, cut holes in the casing, etc and it still works fine. Occasionally the flourescent light for the LCD would flicker out but that was just a matter of opening her up, unplugging the screen, and plugging it back in a couple times. The parts are all Sony, Fujitsu, Toshiba, and other brand names... the laptop runs really hot and sometimes the harddrive (Toshiba) will click a few times and stop working on me which has been happening for a year and just a matter of letting it cool down. Since I never actually move the laptop (there are 6 firewire drives daisy-chained off of a poorly placed 4-pin port in the front center of the laptop) I plan on shelling out the slot fan and copper radiator in favor of some cheap water-cooling experiment (hopefully involving a decorative waterfall).

      My basic point is that a well rated off-brand computer store from pricewatch.com will land you with a Volvo among computers that outruns Miatas, isn't winning design awards, and despite the fact that sometimes it shuts off by itself or won't start immediately it can always be depended on to come up with a few retries and not get any worse with age (my girlfriend's 1984 tank/Volvo is just like this).

      Noise. If you produce less heat you don't need as much cooling, so you don't need to shift as much air. Moving air through a PC makes noise.

      Other than noise, the lower power consumption may not help much for a single PC, but saving 40W per PC when you have 200 or 2000 can add up. Remember you often pay twice for you PC's power consumption - once to heat the air and once for air-con to cool it again.

      electricity is expensive and certainly isn't getting cheaper. If you can get a new box with a Pentium M and a LCD then you are going to use less power even for a more capable rig. This might not matter for your home PC, but it matters if you are running an office with a couple hundred PC's or a business with thousands of them. It also matters if you want a box capable of decoding video but don't want a bunch of noisy fans, or if you run on alternative power. A capable, low power cpu is definitly going to find a niche for itself. Oh yeah and throw 4 of them on a die with a couple megs shared cache and you now have a chip that draws about the same amount of power as a P4 but kicks its butt all over the place on multithreaded code.

      Remember how the P4 was slower than the P3 when it was introduced? They assumed a high clock speed would have fixed this problem, instead it just made a lot more heat. I've seen a 3.4 ghz P4 get hot enough to burn skin.

      • Actually I find browsing nowadays is limited to the shitty browser and the way windows works with files on the hard disks etc.

        If you pump up the threads in firefox and tweak it a little bit plus defrag you can get pages to load fast.

        I'm betting under 98 it could be even quicker as smartdrv was an awesomely fast caching tool whereas XP's is a little safer but ass slow in comparison

    My ideal laptop for college was an Apple G4, but school insisted on Windows for it's 'stability, reliability, and security'.... yea, that's a joke in itself.

    Decided to get an IBM Thinkpad with a Pentium IV Mobile.

    Everyone with laptops running P4's seen to have issues with heat, and power consumption. Despite my oversided screen, dual HD's, and CD-RW... I'm actually doing all right.

    It cost more to get a laptop with a real mobile chip, rather than just a P4 as some companies offer... but I think it saved me a lot of trouble.
    • I'd still get a Powerbook and run Virtual PC, if the performance is any good.

      What is the performance of VirtualPC like on PPC? Anyone know? Emulating a PPC would be slow on x86, being CISC, but how fast is it to emulate a CISC on a RISC processor?
    • First of all, you will only find P4 "Mobile" in P4 laptops. Non mobile versions draw too much juice and have heat dissipation of at least 100W.

      Second of all, Pentium-M blows the doors off P4 "Mobile" while at the same time running much cooler and consuming much less power.

      Third, I type this from a 20" iMac G5. Envy me. :0)

    I think the blurb on the front page was quite misleading. I was pretty blown away by the performance data of the Pentium M. It was on a crappy board with prehistoric features, and it was still kicking ass. It overclocked perfectly to 2.1 Ghz and beat a standard-clocked A64 3500+ on almost every benchmark, and never broke 40C with a tiny little heatsink and a tiny little fan.

    If Intel were serious, they could be making these right now at 2.4 GHz (I'm sure they'd run fine, and still quite cool) at which point it would be beating every desktop processor in the world. I say that's a hell of a start for an Intel processor line. The most important thing is that with such a low heat output, Intel can eventually clock these things pretty high. The Athlon64 seems to have less headroom.

    One clear lesson is that the Pentium4 and everything based on it is done. The P4 gets creamed by the M, it's quite embarassing. I think Intel will just ride out the P4 advertising investment, but we know that their next big thing involves the M cores. And they will be quite fearsome once they start putting multiple M cores into desktop chips, and putting their marketing muscle behind the result.

    I'm a huge AMD fan and will remain loyal, but... I think AMD is in a good place now only because they've consistently out-engineered Intel since the first Athlon. Now I'm scared that they won't pull it off in the next generation. Intel seems to have a really promising starting point.

    A couple of more links
    here [extremetech.com] and here [x86-secret.com].

    At the moment AMD is kicking Intel's arse in the performance sector. The pentium M (Banias) is the only remaining tech that Intel really has. Lots of chickens have come home to roost now that Intel's super-ultra-mega clockspeed boosted chip has reached the end of the line.

    For the sake of a continuing healthy, competive market even the most die hard AMD fans had better hope that Intel gets back on track and allows some engineers to actually make some product decisions for a change. The Banias core seems to be their only hope.

    I have found all of these recent benchmarks to be rather amazing. It's tough for anything to beat an overclocked Pentium M in games even with the huge disadvantages of an aging platform without all the latest goodies. Intel should be embarrassed. Deeply. Their Pentium 4 is a disgrace.

    It is clear that for anyone who cares at all about power consumption, heat, or noise, nothing can touch a Pentium M, not even a Cool n' Quiet enabled 90nm Winchester Athlon64. If Aopen releases a desktop motherboard with the upcoming alviso (PCI-E, DDR2 etc) chipset, things could get very interesting indeed.

    It seems to me that Anandtech didn't run the Linux benchmarks in 64-bit mode for the AMD processors. Given that they are giving an indication of processor performance, they should allow AMD to use that extra gear. It's there to be used!
