Radeon HD 5450 vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which features 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 Texture Address Units and 16 Rasterization Operator Units.

The Radeon RX 560 will be a lot (more or less 1346%) better at AF than the Radeon HD 5450. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 70000 (1346%)

Pixel Rate

The Radeon RX 560 is quite a bit (approximately 623%) faster with regards to FSAA than the Radeon HD 5450, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 16200 (623%)

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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card 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 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
