General info

1.Supports 64-bit
AMD Epyc 7642
Intel Xeon Gold 5218R
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 apps.
2.semiconductor size

14nm

14nm

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
3.Thermal Design Power (TDP)

225W

125W

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.
4.PCI Express (PCIe) version

4

3

Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.
5.Has integrated graphics
AMD Epyc 7642
Intel Xeon Gold 5218R
With integrated graphics you don’t need to buy a separate graphics card.

Performance

1.CPU speed

48 x 2.3GHz

20 x 2.1GHz

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
2.CPU threads

96

40

More threads result in faster performance and better multitasking.
3.L2 cache

24MB

20MB

A larger L2 cache results in faster CPU and system-wide performance.
4.L3 cache

256MB

27.5MB

A larger L3 cache results in faster CPU and system-wide performance.
5.turbo clock speed

3.3GHz

4GHz

When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
6.L1 cache

3072KB

1280KB

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

Memory

1.RAM speed

3200MHz

2667MHz

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

190.7GB/s

119.21GB/s

This is the maximum rate that data can be read from or stored into memory.
3.memory channels

8

6

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

4000GB

1000GB

The maximum amount of memory (RAM) supported.
5.Supports ECC memory
AMD Epyc 7642
Intel Xeon Gold 5218R
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
6.DDR memory version

4

4

DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.

Features

1.Has AES
AMD Epyc 7642
Intel Xeon Gold 5218R
AES is used to speed up encryption and decryption.
2.Supports hardware-assisted virtualization
AMD Epyc 7642
Intel Xeon Gold 5218R
It is easier to obtain better performance when using virtualization if it is hardware-assisted.
3.Has dynamic frequency scaling
AMD Epyc 7642
Intel Xeon Gold 5218R
Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.
4.SSE version

4.2

4.2

SSE is used to speed up multimedia tasks such as editing an image or adjusting audio volume. Each new version contains new instructions and improvements.
5.Has AVX
AMD Epyc 7642
Intel Xeon Gold 5218R
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
6.Has MMX
AMD Epyc 7642
Intel Xeon Gold 5218R
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
