From: Wang Zeep <G.ZEEP%MIT-EECS@MIT-MC.ARPA> Sorry it took so long to summarize these few messages. 1) uVax performance: >From: David_Cathey <dcathey%ti-eg.csnet@csnet-relay.arpa> [...] > I probably shouldn't say anything, but squelching bad rumours won't >hurt. From what I heard from DEC several months ago, uVAX II will not have >the speed of a 780, it should be closer to a 750. I'm afraid my friends still say that 80% of a 780 is the worst of the benchmarks (for some sort of floating point unsupported by the hardware). One even said that some benchmarks go up to 105% of a 11/780! Suggested was the approx. mean of 95%. 2) Upgrades: >From: Richard Garland <OC.GARLAND%CU20B@COLUMBIA> > I have heard from a DEC engineering manager (off the record) that >future micro VAXes would be board replacements for the uVAX I. In fact >the uVAX II was introduced as a chip to some trade group last spring and >I'm sure when DEC can get production efficiency up they will announce it. >The problem (to DEC) as stated by this guy was that the new one should cost >no more than the old (say $2k) and introducing it might be a disincentive >to buy uVAX I's. My sources seems to agree on this one. 3) Not much on array processors. FYI: DEC has announced their workstation product, Vaxstation I, which is composed of a Vaxstation + uVaxI + uVMS. Delivery in December. Of course, all this may be moot in 3 months. Yet another friend at Data General says that they'll have a desktop VAX-sized computer by then, too. I love competition, wz -------
