AMD Athlon II X4 651: 24 facts and highlights

1. total clock speed

2. RAM speed

It can support faster memory, which will give quicker system performance.

3. semiconductor size

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

4. CPU threads

More threads result in faster performance and better multitasking.

5. L1 cache

A larger L1 cache results in faster CPU and system-wide performance.

6. L2 cache

A larger L2 cache results in faster CPU and system-wide performance.

7. PassMark result

This benchmark measures the performance of the CPU using multiple threads.

8. thermal design power (TDP)

The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.

9. L2 core

More data can be stored in the L2 cache for access by each core of the CPU.

10. GeekBench result

This is a cross-platform benchmark that measures the performance of the CPU. (Source: Primate Labs, 2017)

11. Supports 64-bit

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.

12. number of transistors

A higher transistor count generally indicates a newer, more powerful processor.

13. memory channels

More memory channels increases the speed of data transfer between the memory and the CPU.

14. PassMark result (single)

This benchmark measures the performance of the CPU using a single thread.

15. PCI Express (PCIe) version

PCI Express (PCIe) is a high speed expansion card standard, that connects the computer to it's peripherals. Newer versions can support more bandwidth and deliver better performance.

16. Supports hardware-assisted virtualization

It is easier to obtain better performance when using virtualization if it is hardware-assisted.
