Radeon R7 260X vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which makes use of a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

	Difference: 65 Watts (130%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 is 10% quicker than the Radeon R7 260X overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon R7 260X will be quite a bit (about 75%) faster with regards to 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 the exact same pixel fill rate, so in theory they should be 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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 potential to get to the max fill rate.
