General info
The market that the CPU is designed for.
CPU socket
Unknown. Help us by suggesting a value. (AMD Ryzen 7 7745HX)
Unknown. Help us by suggesting a value. (AMD Ryzen 9 7945HX)
The CPU socket/s supported.
Chipset

The motherboard chipset/s supported.
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.
number of transistors

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

Unknown. Help us by suggesting a value. (AMD Ryzen 9 7945HX)
The clock speed of the graphics processing unit (GPU).
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
A graphics processing unit (GPU) with a greater number of execution units can deliver better graphics.
DirectX is used in video games, with newer versions supporting better graphics and features. The latest version is DirectX 12 Ultimate, which includes support for ray tracing, mesh shaders, and variable rate shading (VRS).
Using multiple displays you can create a larger workspace, making it easier to work across multiple apps.
OpenGL is used in games, with newer versions supporting better graphics.
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.
TMUs take textures and map them to the geometry of a 3D scene. More TMUs will typically mean that texture information is processed faster.
The ROPs are responsible for some of the final steps of the rendering process, writing the final pixel data to memory and carrying out other tasks such as anti-aliasing to improve the look of graphics.
Memory
