General info

1.Supports 64-bit
AMD Ryzen 9 3900X
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.
3.GPU clock speed

Unknown. Help us by suggesting a value.

The graphics processing unit (GPU) has a higher clock speed.
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.
If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.
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.
7.DirectX version

Unknown. Help us by suggesting a value.

DirectX is used in games, with newer versions supporting better graphics.
8.number of transistors

Unknown. Help us by suggesting a value.

A higher transistor count generally indicates a newer, more powerful processor.
9.OpenGL version

Unknown. Help us by suggesting a value.

OpenGL is used in games, with newer versions supporting better graphics.

Performance

1.CPU speed

12 x 3.8GHz

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.
A larger L2 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.
A larger L3 cache results in faster CPU and system-wide performance.
A larger L1 cache results in faster CPU and system-wide performance.
7.L2 core

0.5MB/core

More data can be stored in the L2 cache for access by each core of the CPU.
8.Has an unlocked multiplier
AMD Ryzen 9 3900X
Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.
9.L3 core

5.33MB/core

More data can be stored in the L3 cache for access by each core of the CPU.

Memory

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
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.bus transfer rate

Unknown. Help us by suggesting a value.

The bus is responsible for transferring data between different components of a computer or device.
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.
8.eMMC version

Unknown. Help us by suggesting a value.

A higher version of eMMC allows faster memory interfaces, having a positive effect on the performance of a device. For example, when transferring files from your computer to the internal storage over USB.
9.bus speed

Unknown. Help us by suggesting a value.

The bus is responsible for transferring data between different components of a computer or device.

Features

1.Has AES
AMD Ryzen 9 3900X
AES is used to speed up encryption and decryption.
2.Has AVX
AMD Ryzen 9 3900X
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
3.uses multithreading
AMD Ryzen 9 3900X
Multithreading technology (such as Intel's Hyperthreading or AMD's Simultaneous Multithreading) provides increased performance by splitting each of the processor's physical cores into virtual cores, also known as threads. This way, each core can run two instruction streams at once.
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 F16C
AMD Ryzen 9 3900X
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
6.bits executed at a time

Unknown. Help us by suggesting a value.

NEON provides acceleration for media processing, such as listening to MP3s.
7.Has MMX
AMD Ryzen 9 3900X
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
8.Has TrustZone
AMD Ryzen 9 3900X
A technology integrated into the processor to secure the device for use with features such as mobile payments and streaming video using digital rights management (DRM).
9.front-end width

Unknown. Help us by suggesting a value.

The CPU can decode more instructions per clock (IPC), meaning that the CPU performs better
