Ars Technica's Hannibal on IBM's Cell

endersdouble writes "Ars Technica's Jon "Hannibal" Stokes, known for his many articles on CPU technology, has posted a new article on IBM's new Cell processor. This one is the first part of a series, and covers the processor's approach to caching and control logic. Good read."

    Another article on the Cell design at http://www.theregister.co.uk/2005/02/03/cell_analy sis_part_two/ seems to indicate that there is some sort of DRM built in.

    The Cell is designed to make sure media, or third party programs, stay exactly where the owner of the media or program thinks they should stay. While most microprocessor designers agonize about how to make memory accesses as fast as possible, the Cell designers have erected several (four, we count) barriers to ensure memory accesses are as slow and cumbersome as possible - if need be.

    Hannibal doesn't say anything about this (that I noticed) - anyone have more info?

    A budget-class PC laptop of that time might have been about 900 MHz to 1.1 GHz. I wouldn't consider such a laptop anything near useable. They tended to have poor quality sound systems that bottlenecked the processor and atrociously short battery times. The ibook was legendary for its excellent battery performance

    Get off what you 'assume', assumption is just intuition for idiots.

    We have test 200mhz laptops with 80mb of ram 5gb hard drives, released 1997 all running WindowsXP Professional (yes even the themes turned on) and they benchmark faster than they did when they shipped with Windows 95.

    Secondly, they can do full 30fps video as long as it is uncompressed AVI or even WMA 9. QuickTime (MPEG4), MPEG2, and real stutter horribly on video playback unfortunately.

    As for battery, don't know, these laptops hold for 3hrs with a single charge, and yes techs are REQUIRED and have no problems using them daily in test scenarios.

    Now if you really want to compare laptops to laptops, why don't I show you our 900mhz AMD Compaq laptops, they have JBL sound systems in them, and there isn't a single feature the cannot perform with the exception of running a T&L based video game, as the integrated video doesn't handle it, oh wait, the 900mhz PowerBook video didn't support such features either. (BTW, This is not to say that there are not several 900-1000mhz class laptops that have upper end video features), I am just using what we have in our test labs for comparison.

    The 900mhz laptop has a DVD/CDRW, came out late 2000 early 2001 (trying to remember if we got them before holidays or not). They do full software DVD decoding with less than 20% CPU utilization and pretty much do anything fairly fast that we through at them. We even have a beta version of Windows 2003 server running on one with 256mb of RAM. (Yes we are always pushing the limits, but it works as fast as the WindowsXP pro version of the machine sitting next to it.)

    Now off my rant... Macs truly are great, and the PowerBooks of the time were great, but that DOES NOT MEAN they were the BEST, WILL ALWAYS BE THE BEST, or you should be complacent listening to Apple tell you what you are getting is the best when it might not be. It is time for us as MAC users to stand up and DEMAND that technology becomes as much a part of what a MAC is as the EASE of USE in the Interface.

    The time is now, we need to STOP accepting what they tell us and give us and force them to truly give us the LATEST technological concepts, not just the above average concepts when compared to the PC world. These are Macs, they SHOULD BE BETTER. IT shouldn't even be subjected to a debate they should be so far advanced a debate should not be possible. PERIOD.

    Sadly, it just isn't true now, and has not been for many years. OSX has giving the Mac world some credibility backing OS technology, but not Apple needs to take Macs to the next level.

    Even if my comment inspires one Mac user to say hey Apple, we want better, then maybe we all can be the symbolic person with the hammer from their 1984 video and WAKE THEM UP this time.
