GeForce GTX 460 2GB vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which comes with a clock speed of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit bus, and uses a 14 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Radeon RX 550		114688 MB/sec
	Difference: 512 (0%)

Texel Rate

The GeForce GTX 460 2GB will be a little bit (more or less 7%) more effective at AF than the Radeon RX 550. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 2600 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is superior to the Radeon RX 550, and very much so. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 4000 (23%)

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 max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses 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 texture map elements (texels) that can be processed per second. This number is calculated 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 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 maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
