Intel Core i7-660UM

Intel 660UM

The Intel Core i7-660UM is a Ultra Low Voltage dual-core processor for small and light laptops. It is clocked with 1.33 - 2.4 GHz (if Turbo Boost is enabled). The 660UM offers the highest TurboBoost of all 1.3 GHz clocked ULV processors (i3-380UM, i5-470UM, i5-560UM). Each core is based on the Nehalem (Westmere) micro-architecture. Hyperthreading enables the Dual Core CPU to handle 4 threads at once (for a better usage of the pipeline). Compared to the Core i7-620M and the 640LM, the 660UM is much slower (due to the lower clock rate) but more power efficient.

A feature of the new Core i7-660UM is the integrated graphics card (called Intel HD Graphics) and memory controller. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process.

Due to the integrated memory controller, the HyperThreading and Turbo Boost, the  Core i7-660UM is faster than a similar clocked Core 2 Duo (1.33 GHz) in all (us known) applications and benchmarks. Still the Turbo Boost may not trigger very often (sometimes it is even not activated in the BIOS) and therefore the maximum of 2.4 GHz is not very important. All in all the I7-660UM should be faster than a Core 2 Duo SL9300 (1.6GHz).

The 32nm cpu cores of the Westmere generation can also process some new instructions to accelerate AES encryptions. Modern applications that support AES encoding can profit significantly using the new instructions (e.g. the Communications Suite test in the PCMark Vantage boosts up to 70% using AES in the faster Core i5-520M).

The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is between 166-500 MHz (Turbo Boost) and therefore the base speed is clearly below the non low voltage versions. The performance should still be faster than the old GMA 4500MHD.
