I just received my terminator card for this dell gxpro computer. I used to have some 200mhz ppro cpu: 2x256kb, 1x512kb and 1x1mb. This computer used to run debian sarge and win2000, now it's hosting dos6.22 and win98se so it felt kind of a waste to have SMP 2x256 on those OS. The obvious choice was to use the 1024kb cache version but I was curious about the TDP that intel declare of them cpu and how dos and win98 handle l2 cache size difference. In virtual 8086 mode the results where kind of dull, but in real mode some bench in dos started to show difference, so I kept those numbers. I think my choice should be the 512kb as I found it has the best tradeoff power usage/speed, luckily I was able to redress the pins, this cpu was all beaten up and left for dead where I found it. My guess about the 1024kb poor performance is that intel has to somehow slow down the l2 cache of the 1mb version of the ppro to add more and this was not necessary on the 512kb version, something related to row/column delay and that 16bit os didnt care that much about huge amount of l2. I might be wrong, it's just a tough ... so here is the number:
2 x 256kb:
