Radeon R7 M260 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which comes with a core 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 features 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Radeon R7 M260		16000 MB/sec
	Difference: 98688 (617%)

Texel Rate

The Radeon RX 550 will be quite a bit (more or less 105%) more effective at AF than the Radeon R7 M260. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 18040 (105%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 550 is a better choice, and very much so. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 11880 (208%)

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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
