GeForce GT 450 (OEM) vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which comes with core speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 16 ROPs.

Radeon RX 560		80 Watts
GeForce GT 450 (OEM)		106 Watts
	Difference: 26 Watts (33%)

Memory Bandwidth

The Radeon RX 560 should in theory perform a little bit faster than the GeForce GT 450 (OEM) in general. (explain)

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

Texel Rate

The Radeon RX 560 will be quite a bit (more or less 297%) faster with regards to 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 resolution is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon RX 560, but only just. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
