The article concerning the BYTEMark bug is at: |> http://www.byte.com/art/9512/sec4/art2.htm Which was published in December of 1995. Do you think that the same magazine would run the erroneous November 1995 numbers a month after they published their correction? Or the corrected numbers? |> I pointed out this reference since the November 95 article seems to be |> passed around as gospel, quite often without mention of the bug. I clearly identify the text above as taken from the January 1996 Byte. Which was published a month after the corrections were announced. |> Comparative differences between the 133MHz PPC and the 150MHz P6 isn't |> as stark with the corrected BYTEMark benchmarks. |> I did want to point out that I (IMHO) disagree with people posting |> benchmark references without being clear about the systems (cpu, bus, |> cache, memory, core logic, etc) and the compilers (optimization, |> library, etc.) which are used. For instance, one interesting page to |> look at is Granted, Byte did not publish which compiler was used for the benchmarks I quoted. The systems were specified, and one could go to the manufacturers for the rest of the specs. Chris -- Speaking only for myself, of course. Chris Wood christw@lexis-nexis.com cats@erinet.com
