The graphics processing unit GPU has a higher clock speed. Floating-point performance is a measurement of the raw processing power of the GPU. The number of pixels that can be rendered to the screen every second.
GPU memory speed MHz. The memory clock speed is one aspect that determines the memory bandwidth. 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.
GPU turbo Unknown. When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased 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 1. This is the maximum rate that data can be read from or stored into 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. RAM 1GB. 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. 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. Ports 1. HDMI version Unknown. Newer versions of HDMI support higher bandwidth, which allows for higher resolutions and frame rates.
DisplayPort outputs 0. Allows you to connect to a display using DisplayPort. HDMI ports Unknown. More HDMI ports mean that you can simultaneously connect numerous devices, such as video game consoles and set-top boxes. DVI outputs 1. Allows you to connect to a display using mini-DisplayPort. Features 1. DirectX version DirectX is used in games, with newer versions supporting better graphics. OpenGL version 4. OpenGL is used in games, with newer versions supporting better graphics.
OpenCL version 1. Newer versions introduce more functionality and better performance. Should you still have questions concerning choice between the reviewed GPUs, ask them in Comments section, and we shall answer.
