Check out the most significant architectural change in the x86 architecture in 13 years, the Intel Core i7. Intel has completely reinvented its CPU design, removing the antiquated Front Side Bus and replacing it with the new Intel QuickPath Interconnect, delivering up to 6.4 GT/s. Also new to the Core i7 line is the integrated memory controller, supporting Triple Channel DDR3 Memory allowing for more maximum memory, up to 24GB on some boards, and faster access times. Located directly on the CPU die is 256KB per core of L2 cache and 8MB L3 cache shared across all four cores means the CPU can do more without having to access the main memory, further increasing performance.
