I enclose here a previous posting that I use for processor
comparisons. I also claim that if those who bellyache about
their computing speed actually spent the bellyaching time doing
thier computation then these arguments would be moot. 

 Can you perform the computations you want in a timely fasion?
 if no : look into alternatives.

Subject: Benchmarks in August IEEE Micro

In the August issue of IEEE Micro there is a very interesting article
concerning benchmarking 32-bit microprocessors. The following table is
abstracted from page 57. Numbers are time in seconds. (N=no cache enabled;
C=cache enabled). This table reflects the results for dynamic memory.

	 MHz	  E	  F	 H	  I	  K
80286	(10)	 4.89	13.63	6.59	11.20	19.39
80386	(16)	 3.57	 5.16	3.63	 6.86	 6.20
68000	(8)	13.73	14.61	8.79	12.08	16.59
68020 N	(16)	 8.02	 5.55	3.84	 5.65	 4.78
68020 C (16)	 3.84	 2.47	2.14	 2.75	 3.02
32032	(10)	12.52	13.07	6.21	 8.57	13.07
32100 N (18)	16.81	 8.84	5.05	 8.57	 9.17
32100 C (18)	 6.75	 4.29	2.74	 3.63	 4.45

Benchmarks are EDN 16 benchmarks modified for 32 bits. The benchmarks were
coded in assembly code for each processor.

The following EDN programs were used.

Test E is a character-string search routine.

Test F is a bit test, set, and reset routine.

Test H is a linked-list insertion routine.

Test I is a quicksort routine.

Test K is a bit-matrix transposition routine.
