GeForce GTX 260 Core 216 vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which features a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Radeon RX 550		35200 Mtexels/sec
	Difference: 6272 (18%)

Pixel Rate

The Radeon RX 550 will be a bit (about 9%) more effective at anti-aliasing than the GeForce GTX 260 Core 216, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 1472 (9%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
