Radeon HD 5750 1GB vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which makes use of a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 5750 1GB		86 Watts
Radeon RX 480		150 Watts
	Difference: 64 Watts (74%)

Memory Bandwidth

As far as performance goes, the Radeon RX 480 should in theory be quite a bit superior to the Radeon HD 5750 1GB in general. (explain)

Radeon RX 480		262144 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 188544 (256%)

Texel Rate

The Radeon RX 480 should be much (about 540%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon RX 480		161280 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 136080 (540%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 480 is the winner, and very much so. (explain)

Radeon RX 480		35840 Mpixels/sec
Radeon HD 5750 1GB		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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
