General info
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.
With integrated graphics you don’t need to buy a separate graphics card.
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.
DirectX is used in games, with newer versions supporting better graphics.
OpenGL is used in games, with newer versions supporting better graphics.
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
Performance
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.
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.
More data can be stored in the L2 cache for access by each core of the CPU.
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.
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.
The bus is responsible for transferring data between different components of a computer or device.
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.

9.performance per watt
Unknown. Help us by suggesting a value. (Intel Core i9-11900K)
Unknown. Help us by suggesting a value. (Intel Core i9-11900KB)
This means the CPU is more efficient, giving a greater amount of performance for each watt of power used.
Features
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.
AES is used to speed up encryption and decryption.
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
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.
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
6.bits executed at a time
