With three channels of lowly DDR3-1066, you're looking at a whopping 25.6GB/s of memory bandwidth. Crank the memory clock up to 1600MHz, and bandwidth jumps to an even more impressive 38.4GB/s. This fat pipe, combined with the low access latencies inherent to on-die memory controllers, gives the Core i7 a formidable memory subsystem. It also poses an interesting question: how bound by memory speed is Intel's new processor architecture?The reporter concludes that if you're cash-strapped and don't overclock, you don't lose all that much by running the slower, more affordable DIMMs in your Core i7 rig.
