I currently own an AMD 486 DX4-100 (write through) CPU (I also have an AMD 5x86-133 but, for purposes of this discussion, I'm only looking at Intel CPU's).
I was wondering that, if I wanted to upgrade the AMD CPU to an Intel 486 DX4-100 (also the write through model) or an Intel Pentium Overdrive 83 MHz (in write through mode), which one of the two would be best upgrade?
This is now based on overall stability and performance (mostly integer) in both DOS & Windows 95/98.
Reason why I'm mentioning write through and not write back is that I've tested both AMD write through & write back based CPU's and the latter doesn't work very well in "de-turbo" mode, i.e., they don't slow down the overall speed of the CPU that much. My AMD 5x86-133 doesn't perform that well in write through mode with overall speed slightly less than my standard AMD 486 DX4-100 (write through) CPU, which I found odd.
I've never owned any Intel 486DX4 or Pentium Overdrive CPU's and was wondering how they perform overall, as well as in "de-turbo" mode. Does the Intel Pentium Overdrive work well in de-turbo mode?
I have an Asus PVI-486SP3 & VL/I-486SV2G as well as a Lucky Star LS-486E (rev D.) motherboard. From what I can see, all these motherboards support the Pentium Overdrive CPU.
