GeForce GTX 460 (OEM) vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which features a clock speed of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 should perform just a bit faster than the GeForce GTX 460 (OEM) in general. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 5888 (5%)

Texel Rate

The GeForce GTX 460 (OEM) is a small bit (about 3%) better at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 1200 (3%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 (OEM) is a better choice, but not by far. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 3200 (18%)

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 (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
