General info

1.Supports 64-bit
Intel Core i7-3940XM
Intel Core i7-4770K
Intel Xeon E5-2603

A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit applications.

2.Semiconductor size

22nm

22nm

32nm

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

Intel Xeon E5-2603

Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.

Features

1.Has dynamic frequency scaling
Intel Core i7-3940XM
Intel Core i7-4770K
Intel Xeon E5-2603

Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.

2.Has AES
Intel Core i7-3940XM
Intel Core i7-4770K
