Intel Core i7-3820: 27 facts and highlights

1. total clock speed

4 x 3.6GHz
Intel Xeon Platinum 8180: 28 x 2.5GHz

2. RAM speed

It can support faster memory, which will give quicker system performance.
1600MHz
Intel Xeon Gold 5122: 2670MHz

3. semiconductor size

A smaller size indicates that the process to create the chip is newer.
32nm
Intel Celeron J4005: 14nm

4. CPU threads

More threads result in faster performance and better multitasking.
8
Intel Xeon Platinum 8176: 56

5. L2 cache

A larger L2 cache results in faster CPU and system-wide performance.
1MB
Intel Xeon Platinum 8176: 28MB

6. 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.
130W
Intel Atom Z650: 3W

7. 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.

8. L2 core

More data can be stored in the L2 cache for access by each core of the CPU.
0.25MB/core
Intel Core i5-4200Y: 2.5MB/core

9. turbo clock speed

When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
3.8GHz
Intel Core i5-7200U: 3100GHz

10. Has AES

AES is used to speed up encryption and decryption.

11. DirectX version

DirectX is used in games, with newer versions supporting better graphics.
10.1
AMD A6-9550: 12

12. Uses hyperthreading technology

Many of Intel's processors use hyperthreading, which means that each core of the processor can work on two threads at once instead of most processors which work on a single thread per core. This means you can have significant performance gains in certain applications.

15. L3 cache

A larger L3 cache results in faster CPU and system-wide performance.
10MB
Intel Xeon E7-8893 v4: 60MB

16. number of transistors

A higher transistor count generally indicates a newer, more powerful processor.
2270 million
Intel Xeon E5-2699 v4: 7200 million

17. 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.
