Radeon HD 5750 1GB vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which has a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

The Radeon RX 460 2GB should be quite a bit (approximately 142%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 35840 (142%)

Pixel Rate

The Radeon RX 460 2GB is a lot (more or less 56%) faster with regards to FSAA than the Radeon HD 5750 1GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 460 2GB		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 max amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
