GeForce GTX 550 Ti vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 460 2GB		75 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 41 Watts (55%)

Memory Bandwidth

In theory, the Radeon RX 460 2GB should perform a bit faster than the GeForce GTX 550 Ti overall. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 13504 (14%)

Texel Rate

The Radeon RX 460 2GB is quite a bit (more or less 112%) more effective at AF than the GeForce GTX 550 Ti. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 32240 (112%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is the winner, by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 4160 (24%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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