Radeon R7 260X vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

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

Texel Rate

The Radeon R7 260X should be quite a bit (approximately 75%) faster with regards to texture filtering 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 FSAA, and be capable of handling 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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
