1. total clock speed

4 x 3GHz
Intel Xeon Platinum 8180: 28 x 2.5GHz

2. RAM speed

It can support faster memory, which will give quicker system performance.
1866MHz
Intel Xeon Gold 5122: 2670MHz

3. semiconductor size

A smaller size indicates that the process to create the chip is newer.
32nm
Intel Atom C3958: 14nm

4. CPU threads

More threads result in faster performance and better multitasking.
4
Intel Xeon Platinum 8176: 56

5. L1 cache

A larger L1 cache results in faster CPU and system-wide performance.
512KB
AMD Opteron 6180 SE: 1536KB

6. L2 cache

A larger L2 cache results in faster CPU and system-wide performance.
4MB
Intel Xeon Platinum 8176: 28MB

7. PassMark result

This benchmark measures the performance of the CPU using multiple threads.
3638
Intel Core i7-5960X: 16059

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.
100W
Intel Atom Z650: 3W

9. L2 core

More data can be stored in the L2 cache for access by each core of the CPU.
1MB/core
Intel Core i5-4200Y: 2.5MB/core

10. 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.
