GeForce GTX 260 216SP 55 nm vs Radeon RX 550

Intro

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

Performance-wise, the Radeon RX 550 should theoretically be just a bit better 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 a bit (about 18%) faster with regards to anisotropic filtering 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 running with a high resolution is important to you, then the Radeon RX 550 is superior to the GeForce GTX 260 216SP 55 nm, but it probably won't make a huge difference. (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 maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
