As the successor to the Intel Core 2 family published in late 2008, the new Core i series, which is further divided into three areas. The Core i7 represents the most powerful CPUs prepared using many additional functions, and other features to enhance performance. These processors are therefore designed not only for simple workstation, but especially for workstations suitable because even complex calculations can be processed much faster. Whether image and video editing, CAD applications or database systems, opt for one of our workstations used and you will notice the benefits from day one. Of course, our used Core i7 CPUs are also suitable for upgrading a desktop PC, notebook or workstation.

What are the different models are there?

Because extends the Core i series already has four different micro-architectures, it is divided into different generations. The first will then issue a three-digit model number, in the other the corresponding digit is simply prefixed. Thus, for example, the Core i7-3740QM processor, a third generation. The letters indicate doing certain functions. Thus M is mobile, so notebook processors, Q for Quad-Core, X for the Extreme Editions and L, U, Y, S, T for processors with lower power consumption.

What are the benefits for each generation?

1 Generation

These processors are based on the Nehalem or Westmere microarchitecture and offer a maximum of six physical cores in the workstation. For notebooks, however, four cores are the maximum. However, the main difference from the Core i5 of the same generation is activated Hyper-Threading technology, which doubles the number of cores logically. The maximum memory varies depending on model and is 16 to 24 GB of DDR3 RAM in the desktop models and 8 GB for the mobile versions.

2 Generation

In these models, the clock rate and the number of cores behave very similar to its predecessor. However, the Processor Graphics Intel HD Graphics 3000 is added, creating a separate PCI Express graphics card is no longer mandatory. Due to this fact even better running times for the notebook are possible. In addition, 32 GB of memory are now on several models the maximum, which you may notice significant advantages in many applications.

3 Generation

With the Ivy Bridge microarchitecture keep PCI Express version 3.0 and the processor graphics Intel HD Graphics 4000 entered the processors. The latter now permits the operation of three independent monitors. In general, however, improvements to the system and especially on memory access were made. For encryption and cryptography applications are now also functions as Intel AES-NI is available, which for example can be used for key generation.

4 Generation

The new features of the current processors are quite manageable, as it has not changed much in terms of actual computing power. Intel has further here but the internal graphics unit improved as the competitor AMD is slightly further forward still in this area. To allow notebooks with longer maturities and more power-saving features have been built that enable a dynamic adaptation of power. Is the corresponding system is not in use or it is used only for simple tasks, it is reduced to reduce the current consumption and the performance of the processor. So from the Haswell microarchitecture, you benefit primarily in the mobile area of ??the notebooks and high-end tablets.

Intel Core i7 Processor Extreme Edition

These processors are suitable for the most demanding applications and complex calculations. Extreme Edition said CPUs have almost exclusively on 6 cores (12 logic), which are operated at a maximum clock frequency of 4 GHz turbo. The up to 15 MB cache ensures you again for a noticeable performance boost. In addition, are 24 to 64 GB of memory. This has in some models with four memory channels, so that the memory bandwidth to ensure maximum of 59.7 GB / s increases. Due to the enormous power these CPUs can not use the same motherboards, on which the standard editions are operated. For the Extreme editions of the fourth and third generation, for example, the socket LGA2011 is used.
