We took an in-depth look at the architecture behind Intel's all-new Clarkdale (desktop) and Arrandale (mobile) chips in this review. Please read it to gain an appreciation of how and why Intel has decided to change chip topology for 2010.

Built on a 32nm process, the new chips use existing Nehalem architecture technology and add a couple of new features of their own. Known by the umbrella term Westmere, they constitute the first desktop fusion of CPU and GPU in one chip package.

Pricing for the desktop Core i3 and Core i5 Clarkdale chips will span from £80 to around £200 for the range-topping Core i5 670, bringing a bunch of competing mainstream CPUs and integrated graphics into play.

Now we evaluate just how good the Westmere-driven Intel Core i5 661 (£145) is, as we compare it against five other CPUs - four quad-core and another dual-core - and a range of chipsets featuring IGPs. Read on to find out.
