So far we haven’t discussed the influence of memory speed on the performance of LGA1156 platforms built around Core i7, Core i5 and Core i3 processors. In the meanwhile, these CPUs have a number of peculiarities connected closely with the memory: they feature a built-in high-performance DDR3 SDRAM controller, but unlike the LGA1366 modification of Core i7, work with only two memory channels instead of three. Therefore, it is possible that memory specifications may have a somewhat different effect on the performance of LGA1156 systems. We decided to dedicate this article to checking this assumption out, namely, to studying the connection between the bandwidth and latency of DDR3 SDRAM and performance of systems with LGA1156 processors.
