Or you can plump for one of the new low-voltage Arrandale processors and enjoy performance similar to a high-end Core 2 laptop but with much improved battery life.

Reviews Word on the street for the Intel Core i7 620M


9.0
On the one hand, that means you can go with one of these high performance Arrandale chips as reviewed here and enjoy quad-core class performance for the same sort of battery life you get with today's high performance Core 2 laptops.

What People Are Saying Give it to me straight

Socket Type

As for the integrated graphics core, it's a big improvement over previous efforts.
by Tech Radar (Jan, 2010)
Just like the Clarkdale desktop version, the first chip is a 32nm item housing a pair of execution cores and a helping of cache memory.
by Tech Radar (Jan, 2010)
Our review model is the high-end Core i7-620M, a 2.66GHz chip with 4MB of cache memory that clocks up to a maximum of 3.33GHz in Turbo mode (we also have a review of the closely related but more affordable Core i5-540M).
by Tech Radar (Jan, 2010)

Socket

Serving as a yardstick we have an example of Intel's existing Core 2 Duo mobile processor in 2.4GHz trim.
by Tech Radar (Jan, 2010)
On paper, Intel has raised its game to near level pegging with AMD and Nvidia, thanks to full hardware support for the full gambit of modern HD codecs, including VC-1, AVC and MPEG2.
by Tech Radar (Jan, 2010)
This new core still struggles to cope with even older games such as Call of Duty 4, for example.
by Tech Radar (Jan, 2010)

Multicore

In other words, the brands Core i3, i5 and i7 have ceased to mean anything.
by Tech Radar (Jan, 2010)
The labels Core i3, i5 and i7 have literally ceased to bear any relationship to the actual hardware you are buying.
by Tech Radar (Jan, 2010)
So there's real value in stuffing a graphics core in with the CPU if it delivers physical and power consumption efficiencies.
by Tech Radar (Jan, 2010)

Performance

This sort of performance should be a basic human right, as far as we're concerned.
by Tech Radar (Jan, 2010)
It's the biggest step forward in usable laptop performance we've yet seen.
by Tech Radar (Jan, 2010)
The 620M is twice as fast in our HD video encoding and professional rendering benchmarks.
by Tech Radar (Jan, 2010)

Type of CPU

If you're wondering how this is possible, it's down to features such as HyperThreading that come with the Nehalem-class architecture which underpins Intel's latest mobile chips.
by Tech Radar (Jan, 2010)
Smaller, simpler motherboards and fewer power-hungry chips is always a good idea for a laptop.
by Tech Radar (Jan, 2010)
But in notebooks, putting the CPU and graphics into a single package is a winner.
by Tech Radar (Jan, 2010)
