People who say Espresso is three overclocked Broadways miss one very important factor; Espresso has 12 times as much L2 cache as Broadway.

What ? It's just cache! Cache is a form of memory to reduce hits in performance by storing small amounts of frequently accessed data so that accessing it will be faster. Cache isn't some sort of unit for computing y'know.

Cache is an important factor in chip efficiency and hence computing performance. 12x as much cache is a huge advantage.

Yep, agreed cache does matter but computing performance is determined by many factors such as the execution units, the branch predictors, and other things such as decode units. Cache will essentially maintain a more theoretical performance rather than increase but that's not a bad thing. 

If you had 3 Broadways clocked at 1.24GHz with their normal amount of cache each (256kb a piece, so 768kb total) and ran it against Espresso, (which has 3MB cache) the increase in cache would hand a definite advantage to Espresso.

True because the espresso can store more data locally.
