Can anyone validate the amount of L3 cache on the regular Mac Mini with upgraded i7 chip? Store does not indicate anything but the 3MB for the i5 chip. Apple chat line says the i7 is also 3MB. Intel says the i7-2620m chip (if that's the right one) has 4MB on the i7 chip. Apple store says the 13" MBP with i7 has 4MB. Site EveryMac.com indicates it is 4MB. Is 4MB right?
