- I just downloaded a good benchmark file from Garbo comparing the new
- CPU's from Intel, C&T and Cyrix. It's /pc/doc-hard/cpucmp13.zip
-
- It includes descriptions, comparisons and integer and float benchmarks.
- Check it out, it's pretty good! Here's a small excerpt:
-
- |For the Whetstone, Dhrystone, WINTACH, DODUC, LINPACK, LLL, and Savage
- |benchmarks, *higher* numbers indicate *faster* performance.
- |
- |For the MAKE RTL, MAKE TRANCK, and String-Test benchmarks, *lower*
- |numbers indicate *faster* performance.
