The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. Compare that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5.

It is made up of 1664 SPUs, 104 Texture Address Units, and 64 ROPs. It also makes use of a 256-bit memory bus, and uses a 28 nm design. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. The GeForce GTX 970 comes with a clock frequency of 1050 MHz and a GDDR5 memory frequency of 1750 MHz.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. It is measured in millions of texels per second. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). Test Option DX11, FHD (1920x1080), Quality : High (5) AMD Radeon RX 470 4GB. This number is calculated by multiplying the total number of texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. It especially helps with AA, HDR and higher screen resolutions. This allows you to configure multiple monitors in order to create a more immersive gaming experience, such as having a wider field of view. The higher the card's memory bandwidth, the better the card will be in general. The graphics card supports multi-display technology. If it uses DDR type RAM, it must be multiplied by 2 once again. In addition, the RX 560 was also faster than the RX 460 by a good margin. The RX 560 averaged 43 fps in, topping the GTX 1050 by a good margin. It has a strong relative performance against every graphics card here. It is worked out by multiplying the card's interface width by its memory speed. The RX 560 sits between the GTX 1050 Ti and the GTX 1050, falling slower than GTX 1050 Ti by 4.7 and faster than GTX 1050 by 12.3.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second.
