Radeon RX 560 114688 MB/sec
GeForce GT 450 (OEM) 96000 MB/sec
Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 is much (about 297%) better at texture filtering than the GeForce GT 450 (OEM). (explain)

Radeon RX 560 75200 Mtexels/sec
GeForce GT 450 (OEM) 18960 Mtexels/sec
Difference: 56240 (297%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon RX 560, not by a very large margin though. (explain)

GeForce GT 450 (OEM) 18960 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 160 (1%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
