GeForce GTX 260 Core 216 vs Radeon RX 550

Intro

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

GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 2800 (3%)

Texel Rate

The GeForce GTX 260 Core 216 is a little bit (about 18%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 6272 (18%)

Pixel Rate

The Radeon RX 550 will be a little bit (more or less 9%) more effective at AA than the GeForce GTX 260 Core 216, and also able to handle higher 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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
