Agree with Killer. To compare these two CPUs, you need to take into account three primary factors which affect a cpu's performance.
1. IPC (Number of Instructions the cpu processes per clock cycle). The cpu with higher IPC will be faster because in the same time it would complete more tasks than one with lower IPC.
2. L3 cache. Presence of L3 caches makes cpu intensive tasks run better than when it is not there. between two cpus which are identical in every aspect though one lacks the L3 cache, than this cpu will be 20 % slower in certain cpu intensive tasks such as gaming or rendering.
3. Number of cores: More cores are helpful in cases where a program/software can utilize as many resources as are available. A rendering software...
