Radeon RX 460 112000 MB/sec
GeForce GT 450 (OEM) 96000 MB/sec
Difference: 16000 (17%)

Texel Rate

The Radeon RX 460 should be a lot (more or less 222%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GT 450 (OEM) 18960 Mtexels/sec
Difference: 42080 (222%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 450 (OEM) is a better choice, not by a very large margin though. (explain)

GeForce GT 450 (OEM) 18960 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 1520 (9%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
