Modern applications that support AES encoding can profit significantly using the new instructions (e.g. The 32nm cpu cores of the Westmere generation can also process some new instructions to accelerate AES encryptions. All in all the I7-640UM should be faster than a Core 2 Duo SL9300 (1.6GHz). Still the Turbo Boost may not trigger very often (sometimes it is even not activated in the BIOS) and therefore the maximum of 2.26 GHz is not very important. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process.ĭue to the integrated memory controller, the HyperThreading and Turbo Boost, the Core i7-640UM is faster than a similar clocked Core 2 Duo (1.2 GHz) in all (us known) applications and benchmarks. A feature of the new Core i7-640UM is the integrated graphics card (called Intel HD Graphics) and memory controller.
