When Intel launched its Core i5 series, there was a large rush of H55 based motherboards put out to take advantage of the new processors with the latest Intel IGP built right into the CPU package. What you got was a Clarkdale dual core 32nm based processor with the latest Integrated Graphics Processor built on a 45nm process, all in a single package. This implementation seemed to work well for the intended audience and delivered pretty respectable numbers across the board as casual gaming, HD playback and programs that were multi-threaded all showed a benefit. The Intel H57 chipset was also released at this time. What really sets it apart from the H55 chipset that makes it an attractive proposition? This is a question that we should be able to answer with a direct side-by-side comparison of the H55 and H57 based motherboards. In this roundup we will be looking at five different H55/H57 models manufactured by Gigabyte, ASUS and ECS.
