Combining CPU and graphics functionality in a single so-called 'fusion' chip is the shape of things to come. So say both Intel and AMD, its main rival in the computer chip business.
That doesn't necessarily mean it's a good thing, however, as our first taste of a fusion processor in desktop trim recently proved.
But could the laptop version of Intel's new fusion processor, reviewed here in Core i7-620M form, have the makings of a mobile masterpiece?
Certainly, this chip cranks out some eye-popping raw performance numbers given their modest dual-core configuration.
The problem on the desktop is that the inclusion of a relatively weedy integrated graphics processor does little but compromise the thermal footprint of what would otherwise be a stunning little dual-core processor.
Make it mobile
However, for a mobile PC, the idea of reducing the chip count and thereby system complexity makes much more sense. Smaller, simpler motherboards and fewer power-hungry chips is always a good idea for a laptop.
Likewise, graphics performance tends to be less critical, particularly when running on battery power. So there's real value in stuffing a graphics core in with the CPU if it delivers physical and power consumption efficiencies.
All of which means the whole idea of CPU-GPU fusion processors is much more of a goer for mobile.

1. How does this processor stack up against the i7-720QM?
I don't see what's so confusing about the naming scheme -
i7 is the "best" processor, ahead of i5 and i3
M indicates Mobile
L = low-voltage
U = ultra-low voltage
Q = quad
Most computer purchasers think that the only think that matters is the clock speed, or core count followed by clock speed. It's good that intel is doing something to dispel this notion.
