Radeon R7 M260X vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which comes with GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 550 should theoretically be a lot faster than the Radeon R7 M260X in general. (explain)

Radeon RX 550		114688 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 50688 (79%)

Texel Rate

The Radeon RX 550 will be much (about 78%) more effective at texture filtering than the Radeon R7 M260X. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 15400 (78%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 550 is superior to the Radeon R7 M260X, by a large margin. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 11000 (167%)

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 data (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
