- kjs3 6y agoThat's pretty meaningless. The effect of cache is very processor and ISA specific and has a log tail of value (as in, depending on the processor, X amount of cache may get you a 50% speedup, but 2 times X might only give you 60% so is the cost/benefit trade-off worth it). It's plausible that the i7 needs 3 times the cache to get the same benefit and the 64k in the 865. N.B. I don't know for sure that that is the case.
