General info

1.Supports 64-bit
AMD Epyc 7662
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.Thermal Design Power (TDP)

225W

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.
3.PCI Express (PCIe) version

4

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.
4.Has integrated graphics
AMD Epyc 7662
With integrated graphics you don’t need to buy a separate graphics card.

Performance

1.CPU speed

64 x 2GHz

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

128

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

32MB

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

256MB

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

3.3GHz

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

4096KB

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

Memory

1.RAM speed

3200MHz

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

204.8GB/s

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

8

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

4000GB

The maximum amount of memory (RAM) supported.
5.DDR memory version

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 7662
AES is used to speed up encryption and decryption.
2.Supports hardware-assisted virtualization
AMD Epyc 7662
It is easier to obtain better performance when using virtualization if it is hardware-assisted.
3.SSE version

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.
4.Has AVX
AMD Epyc 7662
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
5.Has MMX
AMD Epyc 7662
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
6.Has F16C
AMD Epyc 7662
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.

Benchmarks

1.Cinebench R20 (multi) result
