Honored ContributorThe usage of cpu cores depends on your design.
some fpga projects here use lots of fir and other stuffs but mostly quartus does not use more than 1 core on a EP2C70 FPGA that is nearly full ~80%. the most speedup comes from the cpu clock, thats why i have choosen the E8500 3.16GHz cpu with 2 cores instead of 4 cores. the cpu i had before was the D970 with 3.7GHz HT but the E8500 3.16GHz compiles exactly within half the time. today i would go for the E8600 as i do not see the improvement for quartus with an i7 cpu. The higher the cpu clock and faster the memory the shorter the compile times, that is my experience. 2 cpu cores are enough even if 2 projects are compiled the same time.
