Intel Core i7 is currently the fastest processor of the i-series available to the public for end-user products. They are mostly found in high-end computers such as desktops, laptops, and tablets, where they have recorded remarkable performances. It is the first processor of its kind that uses the Nehalem architecture and is packed with many other capabilities. The Core i7 processors all support 64-bit computations.
In a single intel Core i7 processor, you will find three main blocks: CPU, GPU, and memory controller hub. There is also an IO controller block in the same chip. The adjustment made in this new design architecture is the migration of the memory controller and PCIe controller to the CPU. That, in turn, increases the bandwidth and reduces latency. Intel i7 processors are recommended for test and measurement applications where speed is vital because of the new changes.
Apart from the changes in architecture seen above, there is an introduction of QPI. This point-to-point interconnect offers high bandwidth in both directions. Theoretically, data throughput of up to 25.6GBps can be realized. Processor-intensive applications such as simulations can now take advantage of Intel Core i7 processors.
The Intel Turbo Boost feature in Intel i7 processors makes it possible to get the high performance demanded by the threaded applications while keeping processor power consumption low. How does that work? If an application initiates only two threads, then only two active cores are given full power. The remaining idling cores are put on sleep mode to save power. The same applies if an application only runs one thread.
As we all know, a cache is a small block of high-speed memory within the CPU that stores data temporarily. The Core i7 processors have a shared level 3 cache memory, which can be up to 12MB of capacity. All the cores within the intel i7 processors benefit from this feature, thereby boosting the performance.
