Template:FAQ/Questions/level of performance does

What level of performance does the 400MHz motherboard provide?
The nbench CPU benchmarking utility (with floating point tests disabled, since the Gumstix CPU has no FPU) yields:

TEST	Iterations/sec. Old Index	New Index Pentium 90	AMD K6/233 NUMERIC SORT	152.44	3.91	1.28 STRING SORT	10.753	4.80	0.74 BITFIELD	3.6149e+07	6.20	1.30 FP EMULATION	13.023	6.25	1.44 IDEA	393.08	6.01	1.79 HUFFMAN	21.716	0.60	0.19

Baseline: Pentium 90 with 256 KB cache running MSDOS Baseline: AMD K6/233*, 512 KB L2-cache, gcc 2.7.2.3, libc-5.4.38, Linux 2.0.32

Bottom line: generally about the same speed, or slightly faster, than a 233MHz K6, or about 4-6 times the speed of a Pentium 90.
