Top specs and features

General info

1.Supports 64-bit
AMD Athlon II X4 638

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

32nm

A smaller size indicates that the process to create the chip is newer.
