GeForce GTX 260 vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which has core speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Radeon RX 550		50 Watts
GeForce GTX 260		182 Watts
	Difference: 132 Watts (264%)

Memory Bandwidth

As far as performance goes, the Radeon RX 550 should theoretically be a bit superior to the GeForce GTX 260 overall. (explain)

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

Texel Rate

The GeForce GTX 260 will be a small bit (about 5%) better at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 260		36864 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 1664 (5%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 550 is a better choice, though not by far. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GTX 260		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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 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 clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
