Radeon RX 460 vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core frequency at 1469 MHz. The GDDR5 RAM is set to run at a frequency of 2000 MHz on this model. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 460		112000 MB/sec
	Difference: 150144 (134%)

Texel Rate

The Radeon RX 590 will be much (more or less 247%) better at texture filtering than the Radeon RX 460. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 150496 (247%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 590 is a better choice, by far. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 29568 (170%)

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 information (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
