Radeon R7 M260X vs Radeon RX 550

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 550 should perform much 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 quite a bit (more or less 78%) faster with regards to 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

The Radeon RX 550 should be a lot (approximately 167%) faster with regards to anti-aliasing than the Radeon R7 M260X, and should be able to handle higher screen resolutions without losing too much performance. (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 (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
