Expresso isn't a scaled up Gekko or Broadway. There are similarities but both of those are single core CPUs that can't clock over 1GHz. It's a common misconception that Expresso is '3 x Broadways duct-taped together'.

All we know for certain is that both the CPU and GPU have been customised up the wazoo.

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.
