'was gonna say, the Core i3 has an integrated memory controller
(like the Athlon 64's did) and PCI Express v2.0 support on the chip itself
, which will improve the overall performance of the system far more than losing 9MB of overpriced cache memory from a die shrink that is a decade old when manufacturing costs were wayyyyyy higher.
12MB of cache doesn't have 4x times the hit ratio of 3MB.
- It might in fact only have 1/4 the miss ratio however....
Still if the miss ratio is 1% on the 12MB part, and 4% on the 3MB part.
- The hit ratio is 99% on the 12MB part, and 96% on the 3MB part.
So if the Core i3 is clocked just 3.125% higher, it will outperform the 12MB cache part.
- The memory interface on the Core i3 is 21GB/sec, so in effect the RAM itself almost is a level of cache, when compared to a Core 2 Quad which uses the old-school Front Side Bus technology, which is half as fast (tops) in this case.
