Does anybody know the landmark or norton speed test results for a 25 mhz 386
at? Is the 25 mhz 386's performance great enough when comparing with a
12 mhz 286? There is a great difference between 4.77 mhz 8088 and 12 mhz 80286
is there also a big difference 12 mhz 286 and 25 mhz 386?Any information
or comment will be helpful. thank you.

I don't have Landmark or Norton results, but the following benchmark results tabulated here for several UNIX and DOS machines may be of interest to users with floating point intensive applications. No claim of general usefulness is made for this benchmark - it is too simple and specialized for that. However, I find it useful in comparing machines for the floating-point-intensive digital modem simulation and signal processing applications I am frequently concerned with. ---------------------------------------------------------------------- FORTRAN BENCHMARK: Perform 128 FFT's of COMPLEX*8 1024-point array. The latest version of these results and the benchmark's FORTRAN source are always available via anonymous ftp from trantor.harris-atd.com (26.13.0.98) in the "benchmarks" directory. Please send any results you obtain on unrepresented machines to: sonny@trantor.harris-atd.com (Bob Davis) Thanks, Bob. _______________________________________________________________________________ ******************************************************************************* OS: MACHINE: COMMENT: BENCHMARK (SECONDS): _______________________________________________________________________________ ******************************************************************************* UNIX IBM POWERstation 320 Optimized 1.0 NO OPTIMIZE 3.6 ------------------------------------------------------------------------------- UNIX Sun SPARCstation 2 f77, -O 1.71 NO OPTIMIZE 3.12 ------------------------------------------------------------------------------- UNIX MIPS M-1000 -O option 2.2 NO OPTIMIZE 3.5 ------------------------------------------------------------------------------- UNIX MIPS M-500 NO OPTIMIZE 7.2 ------------------------------------------------------------------------------- VOS Harris H-1200 Software timer 8.9 WALL TIME 10.0 ------------------------------------------------------------------------------- UNIX Encore Single CPU 15.8 ------------------------------------------------------------------------------- UNIX Harris MCX-3 -O, Lightning Board 21.7 NO OPT., Lightning 23.6 -f68881 59.9 -fsoft 106.5 ------------------------------------------------------------------------------- UNIX Sun 3/80 -O option 35.3 NO OPTIMIZE 42.5 ------------------------------------------------------------------------------- DOS Z-386/25 w/387 /FPi87, /Ox, /G2 41.25 Zenith ------------------------------------------------------------------------------- UNIX Sun 3/60 w/MC68881 -O option 44.4 -O option 45.7 -O option 51.6 NO OPTIMIZE 54.1 NO OPTIMIZE 55.6 -fsoft 100.8 ------------------------------------------------------------------------------- DOS 25 Mhz 80386/80387 /FPi87, /Ox, /G2 45 ------------------------------------------------------------------------------- UNIX VAX 11/750 -O option 46.2 NO OPTIMIZE 82.7 ------------------------------------------------------------------------------- UNIX Sun 3/280 -O option 47.2 -O option 51.2 NO OPTIMIZE 56.1 ------------------------------------------------------------------------------- UNIX Sun 3/50 -O option 63.4 -O option 64.1 NO OPTIMIZE 80.0 NO OPTIMIZE 81.6 -fsoft 157.5 ------------------------------------------------------------------------------- DOS 16 Mhz 80386/80387 /FPi87 67 (v.4.1) " 65.7(v.5) /FPi 67 (v.4.1) 65.7(v.5) c/FPc 131 /FPa (IGNORES 80387) 218 /FPi (NO87 set) 728 ------------------------------------------------------------------------------- UNIX Sun 3/180 NO OPTIMIZE 70.0 ------------------------------------------------------------------------------- DOS 12 Mhz 80286, w/80287 /FPi87 (REQUIRES 287) 202 /FPi 202 /FPc87 (REQUIRES 287) 273 /FPc 273 /FPa (IGNORES 287) 293 DOS 12 Mhz 80286, NO 80287 /FPa (Alternate Math) 290 /FPc 917 /FPi 945 ------------------------------------------------------------------------------- DOS 10 Mhz 80286/80287 /FPi87 294 ------------------------------------------------------------------------------- DOS 8 Mhz 80286/80287 /FPi87 295 /FPi 295 /FPc87 429 /FPc 430 /FPa (IGNORES 80287) 572 /FPc (NO 80287) 1825 /FPi (NO 80287) 1876 ------------------------------------------------------------------------------- DOS 10 Mhz 80286/80287 /FPi87 300 ------------------------------------------------------------------------------- DOS 4.77 Mhz XT/8087 /FPi87 478 ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- Except as noted, the DOS machines ran code compiled using MicroSoft FORTRAN Optimizing Compiler v. 4.1 -END- _____________________________________________________________________________ Bob Davis, UofALA'66 \\ INTERNET: sonny@trantor.harris-atd.com | _ _ | Harris Corporation, ESS \\ UUCP: ...!uunet!x102a!trantor!sonny |_| |_| | | Advanced Technology Dept.\\ AETHER: K4VNO |==============|_/\/\/\|_| PO Box 37, MS 3A/1912 \\ VOICE: (407) 727-5886 | I SPEAK ONLY | |_| |_| | Melbourne, FL 32902 \\ FAX: (407) 729-2537 | FOR MYSELF. |_________|

~Landmark 10 MHz 286 (1 Waitstate): 9.5 12 MHz 286 (0 Waitstates): 15.5 16 MHz 386sx (0 Waitstates): 19 25 MHz 386 (no cache, 1 Waitstate) 26 25 MHz 386 (no cache but page-interleaved memory) 33 25 MHz 386 (with cache) 44 33 MHz 386 (with cache) 56 25 MHz 486 (with cache) 112 These values may vary a bit for different boards. These values are for ISA boards, Microchannel boards often work without Waitstates and they are faster than ISA boards without cache at same clock rate.
