While CPW may be arbitrary it's a lot more meaningful then MIPS for the kind of work done on an AS/400. MIPS and Mhz are measurements for a computing environment where chip speed is important, but most (all?) AS/400s aren't involved in compute intensive operations but rather IO intensive operations. The entire machine is architected for IO performance, just look at the concept of an IOP. Which would you rather have in an AS/400 environment: 1) A 2 Ghz Chip with 1 Disk IOP and 4 100Gig drives (With RAID that's 300Gig) Or 2) A 266 Mhz chip with 4 Disk IOPs and 20 16 Gig Drives (With RAID that's 304Gig) We move data all day long, we don't compute the orbit of the space shuttle so IO is more important than MIPS. HOWEVER, for those that want the high Mhz chips we'll get the Regatta chips in an AS/400 2H02. They should be ~2Ghz chips at that point. -Walden PS. CPW isn't actually arbitrary. Isn't it based on a CPW of 1 being a B10? ------------ Walden H Leverich III President Tech Software (516)627-3800 x11 WaldenL@TechSoftInc.com http://www.TechSoftInc.com -----Original Message----- From: Norbut, Jim [mailto:Jim.Norbut@Grubb-Ellis.com] Sent: Thursday, December 27, 2001 10:22 To: 'firstname.lastname@example.org' Subject: RE: Trivia: Processor MHz I have always been interested in this also. <rant/> Considering the CPW (Commercial Processing Workload) is a somewhat arbitrary # that IBM comes up with for basically marketing purposes. Even if you could say how fast it is in MIPS (at least that's a semi-standard speed rating) But CPW.....IBM could say whatever they want....or "re-figure" the formula They use so as to make the new servers sound better than the old ones. </rant> Course when I talk to my M$ buddies and try to explain The speed of the AS/400 system they give me this deer in the headlights look. So they probably think it's quite impressive. <g> -----Original Message----- From: Haase, Justin C.

Granted, the CPW is 4550. I don't care about ibm's speed rating. How fast in MHz do these processors run? My bet is around 266. Some are saying 4-500! I don't think so. Please quantify your results with a reputable source. Thanks! Justin C.
