well i would like to see how that L4 cache stacks up between them as yes the i7-4770R has less L3 but it has a L4 cache which should make up for the less amount of L3 though being one of if not the only CPU with a L4 CPU cache i am unsure how to measure its effects on general processing and in other typical types of consumer loads
Hi David, which specs are wrong? I checked a few against intel and the major ones seem correct. Intel has the i7-4770R at 3.2GHz, turbo to 3.9, with 6mb cache, and the I7-4770k at 3.5GHz turbo to 3.9Hgz, with 8mb cache.
These specs are completely wrong.
