Good for rendering but I use Rtx 2080ti lag for UHD and No iGpu ITS ok for gaming but I don't recommended update windows 11 with 2-4gb ram lag but I recommended 4-8 for gaming and 8-32 for rendering with GPU .I don't recommended use RTX 4090 BECAUSE BOTTLENEK IS 9% with 8gb ram

Pros

  • Cheap
  • Good light gaming

Cons

  • Max ram
  • I need 4 memory channel
  • Where igpu

General info

Type

Desktop

The market that the CPU is designed for.
The CPU socket/s supported.
Chipset

X570, B550, A520, X470, B450

The motherboard chipset/s supported.
Has integrated graphics
AMD Ryzen 9 3900X
With integrated graphics you don’t need to buy a separate graphics card.
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.
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.
A higher transistor count generally indicates a newer, more powerful processor.

Performance

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.
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
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.
A larger L2 cache results in faster CPU and system-wide 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.
L2 core

0.5MB/core

More data can be stored in the L2 cache for access by each core of the CPU.
L3 core

5.33MB/core

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

Benchmarks

This benchmark measures the performance of the CPU using multiple threads.
This benchmark measures the performance of the CPU using a single thread.
Cinebench R20 is a benchmark tool that measures a CPU's multi-core performance by rendering a 3D scene.

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.
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.
performance per watt

Unknown. Help us by suggesting a value.

This means the CPU is more efficient, giving a greater amount of performance for each watt of power used.

Integrated graphics

OpenCL version

Unknown. Help us by suggesting a value.

Some apps use OpenCL to apply the power of the graphics processing unit (GPU) for non-graphical computing. Newer versions introduce more functionality and better performance.

Memory

RAM speed

3200MHz

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.
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.
More memory channels increases the speed of data transfer between the memory and the CPU.
The maximum amount of memory (RAM) supported.
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.
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.
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.
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

instruction sets

SSE 4.2, SSE 4.1, AVX, AES, FMA3, F16C, MMX

Instruction sets are sets of codes that the CPU runs for certain functions.
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.
bits executed at a time

Unknown. Help us by suggesting a value.

NEON provides acceleration for media processing, such as listening to MP3s.
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).
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
Has NX bit
AMD Ryzen 9 3900X
NX bit helps protect the computer from malicious attacks.
VFP version

Unknown. Help us by suggesting a value.

Vector Floating-Point (VFP) is used by the processor to deliver increased performance in areas such as digital imaging.

Miscellaneous

Has AES
AMD Ryzen 9 3900X
AES is used to speed up encryption and decryption.
