Ahem. 68020 * 4 is an "incremental" speed change? The 68030 at 30 Mhz more than matches the SPARC/29000/MIPS crowd in actual performance, and I wouldn't want to bet against Motorola on the 68040, which will probably be out before the '486 (Intel claims 1990 as the ETA for this). Also, my sources tell me that "first silicon" of the 68030 was last April, and general availability at 16 Mhz is 4th Qrtr 87, about the same time Intel finally gets to production of the '386 at 20 Mhz. Given the history of CPU clock speeds, it's a good bet Motorola will be producing 30 Mhz '030's before Intel produces a single 30 Mhz 'x86. Motorola can now achieve significant performance improvements in the '030 simply by increasing the cache sizes and translation lookaside buffer size--a rather minimal design change. Don't be surprised if a "68031" (or whatever) is announced in about a year. --Alan@pdn
