Intel Pentium 997 vs Intel Core i5-470UM

Intel Pentium 997

► remove from comparison Intel 997

The Intel Pentium 997 is an Ultra Low Voltage (ULV) dual core processor for entry-level laptops. It is based on the Sandy Bridge architecture but many of the features like Turbo Boost, Virtualization (VT-x, VT-d), HyperThreading, AES or Trusted Execution are deactivated. The Pentium 997 integrates a graphics card called Intel HD Graphics that is based on the HD Graphics 2000 and clocked from 350 - 1000 MHz.

The performance of the Pentium 997 is somewhat higher than a similar clocked Arrandale Pentium CPU. The Core i3-2357M offers less clock speed but features HyperThreading and a 3MB Last Level Cache.

The 17W TDP rating includes the integrated GPU and memory controller and therefore the 987 is suited for small subnotebooks.

Intel Core i5-470UM

► remove from comparison

The Intel Core i5-470UM is a Ultra Low Voltage dual-core processor for small and light laptops. It is clocked with 1.3 - 1.8 GHz (if Turbo Boost is enabled). 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). AES, VT-d and Trusted Execution are deactivated for the 470UM, compared to the i7 UM CPUs.

The faster i5-560UM and i7-660UM are also clocked at 1.3 GHz but feature a higher TurboBoost frequency.

A feature of the Core i5-470UM 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 i5-470UM is faster than a similar clocked Core 2 Duo (1.3 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 1.8 GHz may not be important.

The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is clocked 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.

The power consumption of 18 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 17 Watt TDP of the Core 2 Duo SL-series (CPU alone).
