GeForce GT 450 (OEM) vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 560 should be just a 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 is quite a bit (more or less 297%) more effective 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 high levels of AA is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon RX 560, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
