nekrosoft13 Posted October 12, 2006 Share Posted October 12, 2006 IBM is expected to push its next-generation Power6 dual-core processors to run at higher speeds, rather than following the Intel/AMD concept for high-end computing that packs more cores on a die. The nee CPU will run at speeds between 4-5GHz with a total of 8Mbytes L2 cache and a 75Gbyte/second link to external memory, according to EETImes.com. The Power6 doubles the frequency and bandwidth of the existing Power5 without increasing its power consumption or the depth of its execution pipeline. The move lets IBM ship the chip as a mid-2007 refresh for its existing p-series server line. "We needed to scale the whole system. When you just pack on more cores and don't scale the cache and memory bandwidth you can't really scale CPU performance as well," said Brad McCredie, a fellow in IBM's Systems and Technology Group. The Power6 will essentially follow the pattern set by IBM with the Power4 and 5 CPUs. The Power4 was among the first computer CPUs to put two cores on a single die. The company packed two dice on a single module for high-end versions of the chip. Intel likewise plans to use multi-chip modules to pack two dual-core dice on a family of quad-core chip modules it will start introducing in November. IBM's move to higher frequencies in its next-generation designs is a departure from the strategy of its competitor Sun Microsystems Inc., which has focused on moving to multicore processors and lower clock speeds as a way to keep power and heat in check. IBM may also surpass Intel in the speed race, although it has not determined exact speeds for shipping parts yet. Intel currently ships versions of its single-core Pentium running at up to 3.8GHz, but it slows its dual-core CPUs down to 2.93GHz or less. Thus the big news for IBM is how it can double frequency while holding the line on power consumption and pipeline depth. New circuit designs and process technology improvements plow the way for the advances. The processor is built in a 65-nm process using IBM's silicon-on-insulator (SOI) and strained silicon technology. IBM applied new techniques in variable gate lengths and variable threshold voltages to squeeze maximum performance per Watt at the transistor level. The chip can be fully operated at as little as 0.8V. In addition, IBM will link its Power CPU for the first time to an external embedded controller. The controller will monitor and adjust power and performance parameters on the CPU based on set power management policies. IBM is now in a systems test and debug phase using the Power6 in high-end, midrange and cluster computers for its p-series servers. http://www.cdrinfo.com/Sections/News/Detai...px?NewsId=18483 Link to comment Share on other sites More sharing options...
bdsams Veteran Posted October 12, 2006 Veteran Share Posted October 12, 2006 interesting, will wait for benchmarks though... Link to comment Share on other sites More sharing options...
Argi Posted October 12, 2006 Share Posted October 12, 2006 interesting, will wait for benchmarks though... Pretty much... I'd like to see core 2 duo running at 4ghz+ though, now that'd be nuts. Link to comment Share on other sites More sharing options...
MiG- Posted October 12, 2006 Share Posted October 12, 2006 Pretty much... I'd like to see core 2 duo running at 4ghz+ though, now that'd be nuts. Even better than 4Ghz+, Heres 5Ghz+ :rofl: :cool: Link to comment Share on other sites More sharing options...
Miuku. Posted October 12, 2006 Share Posted October 12, 2006 Even better than 4Ghz+, Heres 5Ghz+ :rofl: Do that in room temperature, 24/7 for 365 days without having to change any parts, then it counts to something. Link to comment Share on other sites More sharing options...
NienorGT Posted October 12, 2006 Share Posted October 12, 2006 Even better than 4Ghz+, Heres 5Ghz+ :rofl: :cool: *Yawn* PowerPC as 8MB L2 Cache and should get 32MB Cache L3 optional... Also, the Core2Xtreme is for desktop where the Power6 is for workstations/server...They are totaly different, don't compare Orange to Apple...

Japlabot Posted October 12, 2006 Share Posted October 12, 2006 Is a 5GHz Power6 as good as a 2.93GHz Core 2 Duo? Did Apple take a wrong turn with their switch to Intel? Could have Apple used Intel for their notebooks and maintained IBM for their high-performance workstations? Link to comment Share on other sites More sharing options...
Agnes Leroy Posted October 12, 2006 Share Posted October 12, 2006 I think APPLE has made some mistakes..what do you think ? Link to comment Share on other sites More sharing options...
