I have been following discussion about new 'killer micros' and I wonder if anybody have any data to compare new Stardent 3000 four CPU mini with 33-ns IBM RISC system 6000 (e.g. server 540) performance ??? Also, how new Alliant FX/2800 (minimum system, i.e. 8 processor) might compare to above. Jozef Syktus jsyktus@adam.adelaide.ua.oz.au

There is the SPEC data collected so far, including the 32Mhz Stardent, and the 30Mhz (avail late this year) IBM 540, and just for fun, a MIPS 6280. Following shows the 10 benchmark, makring the integer ones with I, followed by the geo-means of the Integer subset, the FP subset, and the overall SPECmark. For each machine, the benchmarks where it is fastest are underlined. 1-I 8-I 13 15 20 22-I 23-I 30 42 47 I-m F-m SPEC 44.5 43.7 37.7 38.3 39.6 44.9 35.6 52.4 52.2 36.8 42.0 42.3 42.2 MIPS 6280,60Mhz ---- ---- ---- ---- ---- ---- 21.0 24.9 33.2 33.1 43.4 23.7 26.7 26.5 65.8 91.0 24.0 44.3 34.7 IBM 6000/540 ---- ---- 17.8 20.3 14.7 19.7 62.9 18.1 18.2108.5 29.1 61.9 18.6 39.1 29.0 Stardent 3010 ---- ----- One of my standard foils uses a SPEC-style graph of these three together to illustrate why it is so important to 1) use your own benchmarks, or 2) When looking at the SPEC stuff, be very careful to avoid generalizing too much from the means, especially on floating point. (This is why SPEC insists on publication of all 10 numbers....) In particular, although the set of the 4 integer numbers appears to be a decent predictor of consistent relative performance, let me pick the which FP benchmark, and I can prove ANY ordering of these 3 machines that I want :-) Note that the 3 machines are, in order: a scalar RISC with a fast clock rate, a super-scalar, and a vector machine. -- -john mashey DISCLAIMER: <generic disclaimer, I speak for me only, etc> UUCP: mash@mips.com OR {ames,decwrl,prls,pyramid}!mips!mash DDD: 408-524-7015, 524-8253 or (main number) 408-720-1700 USPS: MIPS Computer Systems, 930 E.
