Why have L1 caches have been the same size for quite a few generations of Intel Core processors? "Currently Intel's L1D (level 1 data) cache is 512 lines with 64 bytes each, 32 kB. Been that way for a pretty long time. L1D latency with a pointer is mostly 4 cycles. Not sure, but I think having 1024 entries would increase that to 5 cycles.." - vardump, 550 days ago: https://news.ycombinator.com/item?id=9001238 https://news.ycombinator.com/item?id=9001238 The total L1 cache increases as you increase the number of cores though.
