General info

1.Supports 64-bit
AMD Epyc 7282
AMD Epyc 7742
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)

120W

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.
4.PCI Express (PCIe) version

4

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.
5.Has integrated graphics

AMD Epyc 7742
With integrated graphics you don’t need to buy a separate graphics card.

Performance

1.CPU speed

16 x 2.8GHz

64 x 2.25GHz

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

32

128

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

8MB

32MB

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

64MB

256MB

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

3.2GHz

3.4GHz

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

1024KB

4096KB

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

Memory

1.RAM speed

3200MHz

3200MHz

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

85.3GB/s

190.7GB/s

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

8

8

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

4000GB

4000GB

The maximum amount of memory (RAM) supported.
5.Supports ECC memory
AMD Epyc 7282
AMD Epyc 7742
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 7742
AES is used to speed up encryption and decryption.
2.Supports hardware-assisted virtualization
AMD Epyc 7282
AMD Epyc 7742
It is easier to obtain better performance when using virtualization if it is hardware-assisted.
3.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.
4.Has AVX
AMD Epyc 7282

F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.

Benchmarks

1.Cinebench R20 (single) result

373

398

Cinebench R20 is a benchmark tool that measures a CPU's single-core performance by rendering a 3D scene.
2.Blender (bmw27) result

119.2seconds

33.9seconds

The Blender (bmw27) benchmark measures the performance of a processor by rendering a 3D scene. More powerful processors can render the scene in less time.
3.Blender (classroom) result

353.8seconds

95.8seconds

The Blender (classroom) benchmark measures the performance of a processor by rendering a 3D scene. More powerful processors can render the scene in less time.
