Radeon HD 5670 vs Radeon RX 460

Intro

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

Radeon HD 5670		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The Radeon RX 460 will be a lot (approximately 294%) better at texture filtering than the Radeon HD 5670. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 45540 (294%)

Pixel Rate

The Radeon RX 460 will be much (approximately 181%) faster with regards to FSAA than the Radeon HD 5670, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 11240 (181%)

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 data (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
