GeForce GTX 260 216SP 55 nm vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which uses a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 260 216SP 55 nm		171 Watts
	Difference: 121 Watts (242%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 should perform a little bit faster than the GeForce GTX 260 216SP 55 nm in general. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 260 216SP 55 nm		111888 MB/sec
	Difference: 2800 (3%)

Texel Rate

The GeForce GTX 260 216SP 55 nm will be just a bit (approximately 18%) faster with regards to AF than the Radeon RX 550. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 6272 (18%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 550 is a better choice, but not by far. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
	Difference: 1472 (9%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
