Radeon HD 5750 512MB vs Radeon RX 480 4GB

Intro

Compare all that to the Radeon RX 480 4GB, which makes use of a 14 nm design. AMD has clocked the core frequency at 1120 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this specific model. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 480 4GB		150 Watts
	Difference: 64 Watts (74%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 4GB should be quite a bit faster than the Radeon HD 5750 512MB in general. (explain)

Radeon RX 480 4GB		229376 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 155776 (212%)

Texel Rate

The Radeon RX 480 4GB will be a lot (about 540%) more effective at anisotropic filtering than the Radeon HD 5750 512MB. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 136080 (540%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 480 4GB is a better choice, and very much so. (explain)

Radeon RX 480 4GB		35840 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 24640 (220%)

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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
