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.

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.

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 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.

If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.

With integrated graphics you don’t need to buy a separate graphics card.

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).

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

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.

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

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

A larger L2 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.

The clock multiplier controls the speed of the CPU.

Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.

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.

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.

The maximum speed of RAM that is supported by the CPU.

The maximum amount of memory (RAM) supported.

More memory channels increases the speed of data transfer between the memory and the CPU.

The bus is responsible for transferring data between different components of a computer or device.

The bus is responsible for transferring data between different components of a computer or device.

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.

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.

Instruction sets are sets of codes that the CPU runs for certain functions.

NEON provides acceleration for media processing, such as listening to MP3s.

The CPU can decode more instructions per clock (IPC), meaning that the CPU performs better

NX bit helps protect the computer from malicious attacks.

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).

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