General info

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

267mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.

Performance

The graphics processing unit (GPU) has a higher clock speed.
2.pixel rate

36.7 GPixel/s

The number of pixels that can be rendered to the screen every second.
Floating-point performance is a measurement of the raw processing power of the GPU.
The memory clock speed is one aspect that determines the memory bandwidth.
5.texture rate

147 GTexels/s

The number of textured pixels that can be rendered to the screen every second.
Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.

Memory

The effective memory clock speed is calculated from the size and data rate of the memory. Higher clock speeds can give increased performance in games and other apps.
This is the maximum rate that data can be read from or stored into memory.
Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.
A wider bus width means that it can carry more data per cycle. It is an important factor of memory performance, and therefore the general performance of the graphics card.
Newer versions of GDDR memory offer improvements such as higher transfer rates that give increased performance.
6.Supports ECC memory

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.

Features

DirectX is used in games, with newer versions supporting better graphics.
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.
The number of GPUs supported when using a multi-GPU configuration. Using more than one GPU in parallel can give increased performance.
