General info

1.Supports 64-bit
AMD Ryzen 9 3900X
Intel Core i9-10900K
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.
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.
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.
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.
If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.
6.Has integrated graphics
AMD Ryzen 9 3900X
Intel Core i9-10900K
With integrated graphics you don’t need to buy a separate graphics card.

Performance

1.CPU speed

12 x 3.8GHz

10 x 3.7GHz

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

6MB

2.5MB

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

64MB

20MB

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

768KB

640KB

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

Memory

1.RAM speed

3200MHz

2933MHz

It can support faster memory, which will give quicker system performance.
This is the maximum rate that data can be read from or stored into memory.
More memory channels increases the speed of data transfer between the memory and the CPU.
The maximum amount of memory (RAM) supported.
5.Supports ECC memory
AMD Ryzen 9 3900X
Intel Core i9-10900K
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.
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 Ryzen 9 3900X
Intel Core i9-10900K
AES is used to speed up encryption and decryption.
2.Has dynamic frequency scaling
AMD Ryzen 9 3900X
Intel Core i9-10900K
Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.
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 Ryzen 9 3900X
Intel Core i9-10900K
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 Ryzen 9 3900X
Intel Core i9-10900K
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
6.Has F16C
AMD Ryzen 9 3900X
Intel Core i9-10900K
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
