Message-ID: Date: 27 Nov 90 11:56:15 GMT Sender: news@travis.csd.harris.com Organization: Harris Computer Systems Division Lines: 17 I see a lot of the current and near current top of the line RISC chips and other microprocessors coming out with a 33MHz clock rate. In a similar way the previously most popular number seemed to be 25MHz. Is there some hardware related magic about certain clock rates that makes it likely for totally different manufacturers of totally different chips to come out with chips with the same clock rates in similar time frames? Obviously they all need to stay competitive, but why do they lots of them wind up at exactly 33? Why not 30 or 35? -- ====================================================================== domain: tahorsley@csd.harris.com USMail: Tom Horsley uucp: ...!uunet!hcx1!tahorsley 511 Kingbird Circle Delray Beach, FL 33444 +==== Censorship is the only form of Obscenity ======================+ | (Wait, I forgot government tobacco subsidies...) | +====================================================================+
