The Core arch is ~35% faster than the K8 arch at equivalent clock rates.
Altair / K8L will clock at 2.9 Ghz max.
Yorkfield XE will clock at 3.73 Ghz max.
Lets give a K8 at 2.9 Ghz a baseline performance rating of 1.0. Now the claimed performance increase of K8L over K8 is about 40%. Then the Altair / K8L will rate at 1.4.
Lets assume the Intel Yorkfield XE only performs as well as an existing Core arch chip, clock for clock. This will underestimate its performance, but lets assume this for now. Therefore, the Yorkfield XE will rate at: 3.7/2.9 * 1.35 = 1.72
Therefore:
Intel Yorkfield XE will be 1.72/1.4 = ~23% faster than the AMD K8L!
Now lets be more generous to Intel and say that, clock for clock, the monolithic Yorkfield will be 10% faster than the existing core arch. (Remember AMD claims a 40% advantage for the move to a monolithic quad core). Therefore, the Yorkfield XE will rate at: 3.7/2.9 * 1.35 * 1.1 = 1.89
Therefore:
Intel Yorkfield XE will be 1.89/1.4 = ~35% faster than the AMD K8L!
This is just on performance alone. Given that the Yorkfield uses a 45 nm process it should use about half the power than the 65 nm K8L does too.
8O for AMD
