Intel Core i7-3820 review: 27 facts and highlights

1. total clock speed

4 x 3.6GHz
Intel Xeon Phi 7235: 64 x 1.3GHz

2. RAM speed

It can support faster memory, which will give quicker system performance.
1600MHz
AMD Ryzen 5 2400GE: 2933MHz

3. CPU threads

More threads result in faster performance and better multitasking.
8
Intel Xeon Phi 7235: 64

4. semiconductor size

A smaller size indicates that the process to create the chip is newer.
32nm
AMD Ryzen 5 2600: 12nm

5. L2 cache

A larger L2 cache results in faster CPU and system-wide performance.
1MB
Intel Xeon Phi 7235: 32MB

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 E3805: 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.
