General info

1.Supports 64-bit
AMD Ryzen 9 3900X
Intel Core i7-10700K
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. (AMD Ryzen 9 3900X)

350MHz

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.
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.
7.DirectX version

Unknown. Help us by suggesting a value. (AMD Ryzen 9 3900X)

12

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

Unknown. Help us by suggesting a value. (AMD Ryzen 9 3900X)

Unknown. Help us by suggesting a value. (Intel Core i7-10700K)

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

4.5

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

Performance

1.CPU speed

12 x 3.8GHz

8 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.
5.L3 cache

64MB

16MB

A larger L3 cache results in faster CPU and system-wide performance.
6.L1 cache

768KB

512KB

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

0.5MB/core

0.25MB/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
Intel Core i7-10700K
Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.
