Radeon R7 260X vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 should perform 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 is quite a bit (approximately 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 the exact same pixel fill rate, so in theory 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
