Radeon HD 5750 1GB vs Radeon RX 460

Intro

Compare that to the Radeon RX 460, which uses a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular model. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Radeon HD 5750 1GB		73600 MB/sec
	Difference: 38400 (52%)

Texel Rate

The Radeon RX 460 should be a lot (more or less 142%) better at texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 35840 (142%)

Pixel Rate

The Radeon RX 460 should be quite a bit (more or less 56%) better at AA than the Radeon HD 5750 1GB, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 6240 (56%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
