General info
Type
Desktop
The market that the CPU is designed for.
CPU socket
AM4
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.
CPU temperature
95°C
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.
number of transistors
7600 million
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.
turbo clock speed
4.6GHz
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.
L2 cache
6MB
A larger L2 cache results in faster CPU and system-wide performance.
L3 cache
64MB
A larger L3 cache results in faster CPU and system-wide performance.
L1 cache
768KB
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

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

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
