These consumer-level chips are said to be as fast (or faster) than Intel’s upcoming professional line” oscast has an http://www.oscast.com/stories/storyReader$130“>interesting on this. 2003-02-19 4:54 am That URL came up bad… make that: http://www.oscast.com/stories/storyReader$130 2003-02-19 9:54 am “chip will have four times the performance than those using the current Power4” I wonder if this is a microprocessor measure or a global improve measure. Why is needed a so fast CPU with a disk 10000 times slower? Is not this micro over dimensioned? Really increase the time needed to solve a SQL query? 2003-02-19 1:45 pm Just store load all the data into RAM. 2003-02-19 3:32 pm Besides what andrew said, and he’s correct Think about the fact that a CPU is around for a long time, the hard drives and other hardware will get faster before it’s life is over. Also I wouldn’t be surprised if in the near future Large computers like servers and mainframes switched to solid state harddrives, since they are always powered with good UPS’s, though they would still have real harddrives in there to back everything up. Yes the harddrive is slow but rarely do you access it so much you flog the thing, if you are you probably need more memory. Yes a server and such is pretty much just a big file cabinet writting stuff to disk but even then the drives manage, plus they are in big fast raid setups. And from a business perspective saying your chips are 4 times faster then the compitions and thats yourself isn’t a bad thing at all. 2003-02-19 5:27 pm I like reading news about the ferrari chips. Thanks for the link. 2003-02-19 8:45 pm The comment about solid state disks is probably dead on. Plus, doesn’t the current power4 have 128 megs of L3 cache per 8 processors? That right there probably gives a huge boost to database search speed and if they quadruple the size or something in the Power5 then you could probably hold the most commonly used parts of even a large database in there and they could be acessed virtually instantly. 2003-02-19 11:20 pm I wonder if this is a microprocessor measure or a global improve measure. Obviously it’s a measure of how the Power5 compares in terms of raw processor performance to the Power4. Why is needed a so fast CPU with a disk 10000 times slower? Is not this micro over dimensioned? Really increase the time needed to solve a SQL query? Because many tasks are not I/O bound in the slightest, but are completely CPU bound. Obviously if a task is I/O bound a faster processor isn’t going to increase performance greatly. However, many tasks alternate between being CPU bound and I/O bound (i.e. dynamic linking) In general, a faster CPU will improve your overall performance. And with x86 having been the price/performance leader, and now bordering upon being the overall performance leader, it’s really time for the Power ISA and others to make a showing.
