Why do Intel core i7 have small L2 cache? Tags: CPUs Core Cache Intel i7 Last response: May 17, 2012 3:49 PM in CPUs Share darkstar845 May 17, 2012 12:47:41 PM I just noticed that from the core i7 first gen to 3rd gen that they all have only 256kb L2 cache per core but have a 8mb L3 cache. Core 2 quads used to have 4mb to 12mb L2 cache and current AMD cpus still have large L2 cache.

There may have been improvements in how they managed L2 cache, and how efficiently they could transfer from L3 to L2, if that improved then there was no need for vast arrays of L2 cache.

So you have a tradeoff: Do you want a higher chance to hit the L2 cache but at a cost to latency, or less of a chance to hit the cache, but with very fast access times? Because of the L3, there is not a need for a large L2. Can't find your answer ? Ask ! Publish Related resources Intel 's L1 & L2 &L3 Cache Forum Intel Nehalem 55XX and L1 and L2 cache sizes. Small ?
