The fundamental difference between the technology with the latest Core i7 Core 2 Quad is located in Duo/Core2 IMC (Integrated Memory Controller). In the Core 2 Duo / Core 2 Quad, IMC is embedded in the chipset (X38, X48, P45, and so on). . This causes the throughput capacity of memory depends on the chipset capabilities. While the Core i7, IMC moved to the processor so that the chipset could theoretically work is lighter and memory bandwidth throughput speeds much faster because they do not need to pass the chipset (Northbridge).
Differences architecture Duo/Core2 Core 2 Quad with Core i7
Front Side Bus 1066, 1333 and 1600 MHz processor known in the Core 2 Quad Duo/Core2 turned into QPI (Quick Path Interconnect) on the Core i7. Similarly, the former FSB speeds up to 1.6 GT / s-fold to 6.4 GT / s. This is because the speed of internal memory controller on the CPU is more effective than the Northbridge memory controller, not to mention the added implementation of Triple Channel DDR3 Core i7 platform. Although, the benefits or effects of the implementation of Triple Channel DDR3 is still not very significant in real applications.

In addition, the Intel Core i7 back Hyperthreading technology implementation (HT) or also known as Simultaneous Multi-Threading (SMT). Total core processors on Core i7 amounted to 4 fruit core (core) and each core has a SMT, so that a total of 8 thread on a Core i7 processor.
QPI (Quick Path Interconnect)
QPI is a replacement bus speed FSB, if the FSB is the data transmission path between the chipset, processor and memory, even simpler QPI. QPI is a data transmission speed of the processor to the chipset. If previously we know as the Northbridge chipset is set processor, memory and PCI-E lane, then the Core i7 processor, chipset, known as the IOH (Input-Output Hub) which serves as the input and output lines of the entire system.
