i7 or intel core i7 is one of the latest producted processor by Intel company. The fundamental difference between the technology with the latest Core i7 Quad Core 2 Duo/Core2 lies in the IMC (Integrated Memory Controller). On Core2 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 transferred to the processor so that the chipset could theoretically work lighter memory bandwidth and throughput speed is faster because it does not need to pass through the chipset (Northbridge).
Differences Duo/Core2 Core 2 Quad architecture with Core i7
Front Side Bus 1066, 1333 and 1600 MHz which is known in Duo/Core2 Core2 Quad processor to change into the QPI (Quick Path Interconnect) on Core i7. Likewise, the former FSB speeds up to 1.6 GT / s doubled to 6.4 GT / s. This is because the speed of the internal memory controller on the CPU is more effective than the memory controller on the northbridge, 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 Core i7 Intel Hyperthreading technology re-implementing (HT) or also known as Simultaneous Multi Threading (SMT). Total core processors on Core i7 consists of 4 pieces (core) and each core has SMT, bringing the total there are 8 threads on a Core i7 processor.
QPI (Quick Path Interconnect)
QPI is a replacement bus speed FSB, if FSB is the data transmission path between the chipset, processor and memory, QPI simpler. QPI is a data transmission speed of the processor to the chipset. If previously we know as the Northbridge chipset that regulates the processor, memory and PCI-E, then the Core i7 processor, chipset known as IOH (Input-Output Hub), which served as the input and output lines of the entire system.
