GeForce GTX 460 1GB vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which comes with GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

The GeForce GTX 460 1GB is just a bit (approximately 7%) better at AF than the Radeon RX 550. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 2600 (7%)

Pixel Rate

The GeForce GTX 460 1GB should be quite a bit (more or less 23%) more effective at FSAA than the Radeon RX 550, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 460 1GB		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 (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, 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 number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
