Radeon R7 260X vs Radeon RX 550

Intro

The Radeon R7 260X features a clock frequency of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

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

Power Consumption (Max TDP)

Radeon RX 550 50 Watts
Radeon R7 260X 115 Watts
Difference: 65 Watts (130%)

Memory Bandwidth

Theoretically, the Radeon RX 550 should perform just a bit faster than the Radeon R7 260X overall. (explain)

Radeon RX 550 114688 MB/sec
Radeon R7 260X 104000 MB/sec
Difference: 10688 (10%)

Texel Rate

The Radeon R7 260X will be a lot (more or less 75%) more effective at AF than the Radeon RX 550. (explain)

Radeon R7 260X 61600 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 26400 (75%)

Pixel Rate

Both cards have exactly the same pixel rate, so theoretically they should perform equally good at at full screen anti-aliasing, and be able to handle the same screen resolutions. (explain)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
