SparcServer 1000

With 3 CPUs your 1000 will probably give you close to the floating point performance of your Ultra 1 on a typical cruncing application (13 MB/processor) well distributed among the CPUs (no memory contention). I don't know about integer performance because I don't deal too much with it. The I/O busses in your Ultra-1 are likely to be faster in Ultra-1 than in the 1000. Depending upon the number and vintage of the disk drives in each this may or may not be a constraint. The 4 processor 1000 I have access to here clocks in a 0.00053 second Ahl's simple benchmark (4 process multiprocessing). The Ultra-10 (350MHz) on my desk does about 0.00078 seconds. Of course that's a 7k executable, so it caches pretty well, but the 1000 beats the Ultra in raw CPU. The 1000 has a non-Sun CPU upgrade, so its times should be better than a stock 1000. Of course the primary difference will be memory bandwidth. The Ultra-10 can move 123 MB/s (stream_d) while 1000 is lucky to get 32 MB/s. Eric
