Sony :: New Z (i5) CPU Vs. Current Z (C2D) CPU

As an example my Z laptop has the P9500 C2D... but for arguments sake lets say I have a P8600 (same GHz as the new Z's CPU).

Current Z P8600:

Max TDP: 25 W
2 Cores @ 2400 MHz
Fully threaded application on both cores:
2.4Ghz * 4 Ops/Clock * 2 Cores = 19.2 GFLOP
Single threaded application (very common) on ONE core:
2.4Ghz * 4 Ops/Clock * 1 Cores = 9.6 GFLOPS
(GFLOPS is a great baseline on how fast is the CPU rating--giga floating point operations per second)

The new Z apparently has (at least confirmed so far) an Core i5-520M:...............
