I currently have plans for a similar socket 7 comparison whereby all socket 7 CPUs will be tested on the same system. For completeness, I will include the PII-400, Cyrix 5x86, and POD results, in which case the results will no longer strictly be socket 7. A loosely translated title of this type of comparison may read, The Ultimate 586 Benchmark Comparison.
The CPUs in this study will include:
Cyrix
5x86 - 100 MHz (33 MHz x 3.0) for comparison against 6x86-100
5x86 - 120 MHz (40 MHz x 3.0) for comparison against 6x86-120
5x86 - 133 MHz (33 MHz x 4.0) for comparison against 6x86-133
6x86 - 75 MHz (50 MHz x 1.5)
6x86 - 90 MHz (60 MHz x 1.5) - U
6x86 - 100 MHz (66 MHz x 1.5) - U
6x86 - 120 MHz (60 MHz x 2.0)
6x86 - 133 MHz (66 MHz x 2.0)
6x86L - 150 MHz (60 MHz x 2.5)
6x86MX - 166 MHz (66 MHz x 2.5) - U
6x86MX - 200 MHz (66 MHz x 3.0)
MII - 233 MHz (66 MHz x 3.5) - U
MII - 250 MHz (83 MHz x 3.0)
MII - 266 MHz (66 MHz x 4.0) - U
MII - 300 MHz (75 MHz x 4.0)
MII - 333 MHz (83 MHz x 4.0) - O
Intel
P24T - 83 MHz (33 MHz x 2.5)
P24T - 100 MHz (40 MHz x 2.5) - O
P54C - 75 MHz (50 MHz x 1.5)
P54C - 90 MHz (60 MHz x 1.5)
P54C - 100 MHz (66 MHz x 1.5)
P54CS - 120 MHz (60 MHz x 2.0)
P54CS - 133 MHz (66 MHz x 2.0)
P54CS - 150 MHz (60 MHz x 2.5) - U
P54CS - 166 MHz (66 MHz x 2.5)
P54CS - 200 MHz (66 MHz x 3.0)
P55C-MMX - 100 MHz (?) - U
P55C-MMX - 166 MHz (66 MHz x 2.5) - U
P54C-MMX - 200 MHz (66 MHz x 2.5) - U
P54C-MMX - 233 MHz (66 MHz x 3.5)
P54C-MMX - 266 MHz (66 MHz x 4.0)
P54C-MMX - 300 MHz (75 MHz x 4.0) - O
P54C-MMX - 333 MHz (83 MHz x 4.0) - O
PII - 400 MHz (100 MHz x 4.0)
AMD
K5 - 100 MHz (66 MHz x 1.5)
K6-2 - 100 MHz (?) - U
K6-2 - 266 MHz (66 MHz x 4.0)
K6-2 - 300 MHz (75 MHz x 4.0) - O
K6-2 - 500 MHz (83 MHz x 6.0) - U
K6-3+ - 400 MHz (66 MHz x 6.0) - U
K6-3+ - 450 MHz (75 MHz x 6.0)
K6-3+ - 500 MHz (83 MHz x 6.0) - O
IDT
Winchip - 200 MHz (66 MHz x 3.0)
Winchip2 - 233 MHz (66 MHz x 3.5)
Winchip2 - 266 MHz (66 MHz x 4.0) - O
In cases where I do not have the actual CPU at the specified frequency, a closely matched CPU will be benchmarked in its place (slightly over/under clocked, provide that the CPU architecture is the same). U stands for an underclocked CPU while O stands for an overclocked CPU. The clock frequencies noted are actual clock frequencies, not the PR rating using by IDT, Cyrix6x86/MII, and AMD K5's. For example a Cyrix MII-400GP will be used for the 300 MHz test.
It will be interesting to do a clock-for-clock comparison at 100 MHz with POD100, Cyrix 5x86-100, K5-100, Intel100, Cyrix 6x86-100, and perhaps too the the K6-100 and MMX-100 if they will downclock well.
Is there any CPU of particular interest I have left out? I can only go up to 500 MHz for AMD and 333 MHz for Cyrix. If the Intel CPU's are locked, then I am stuck with a 4x multiplier, for which 333 MHz will be the max I can test on this non-super socket7. The BIOS has been modified to allow for proper K6 II/III+ operation as well as Cyrix 4x, with a maximum FSB of 83.3 MHz.
