Date: 22 Aug 1996 From: Don Yuniskis To: 386EX@teleport.com (386EX Users) Subject: Re: Performance figures..? (fwd) Thanks to Ian Stirling for forwarding this stuff to me. I'm taking most of it out of context and fowarding it along just FYI. Note that I'm not claiming it's a "real" or "pertinent" benchmark. But, it does hold *some* information. I had suspected the 386EX would perform at roughly 60% of the 386DX and was surprised to see an apparently higher level of performance (though the details have been omitted and it's hard to tell if we're comparing apples to aardvarks!) [note "Comparison" column only and assume EX is roughly SX] Any other performance-related comments folks would like to add? --don > As a very approximate guide, the BogoMips can be calculated by: > > System BogoMips Comparison > Intel 8088 clock * (0.004 plusminus 0.001) 0.02 > Intel/AMD 386SX clock * (0.14 plusminus 0.01) 0.8 > Intel/AMD 386DX clock * (0.18 plusminus 0.01) 1 (definition) > Motorola 68030 clock * (0.25 plusminus 0.005) 1.4 > Cyrix/IBM 486 clock * (0.34 plusminus 0.065) 1.8 > Intel Pentium clock * (0.40 plusminus 0.035) 2.2 > Intel 486/AMD 5x86 clock * (0.50 plusminus 0.01) 2.8 > Mips R4000/R4400 clock * (0.50 plusminus 0.015) 2.3 > Nexgen Nx586 clock * (0.75 plusminus 0.010) 4.2 > PowerPC 601 clock * (0.84 plusminus 0.015) 4.7 > Alpha (all) clock * (0.99 plusminus 0.005) 5.5 > Intel Pentium Pro clock * (0.99 plusminus 0.005) 5.5 > Cyrix 5x86/6x86 clock * (1.00 plusminus 0.005) 5.6 > Mips R4600 clock * (1.00) 5.6 > AMD 5k86 clock * (2.00 plusminus 0.010) 11.1 > Motorola 68060 clock * (2.01) 11.2 > > Motorola 68040 (insufficient data yet) > Sparc (insufficient data yet) > > - Note that the BogoMips calculation loop does not take > advantage of the parallelism of various processors, such > as the Intel Pentium and the Alpha 21164. > - Note that the BogoMips calculation loop for the non-Intel > CPUs is similar but not the same. Date: 19970502 From: Mike Sprecher Organization: Brainware Catalyst To: Jaap van Ganswijk Subject: BogoMIPS Hi, (its me again...) The BogoMIPS page shows very inaccurate benchtests. The MC68060 would never ever be as fast as a, say MCP601 or PPro. Note that the 68060 is only available at a clock of 50 (100internal) MHz. It's very fast rating it with MIPS per MHz. Also the 601 is faster than the Intel pentium what concerns floating point ops. I have collected manufacturer's data on their CPU's where one can see the differences (allthought here the provided data varies very much too. Intel uses rather "high" values while motorola is moderated... If you have a Macintosh, I can send you the database to take a look at. It's Claris Filemaker 3.0.4 Catalyst
