GeForce GTX 260 Core 216 vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which uses 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 model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 152 Watts (304%)

Memory Bandwidth

The Radeon RX 550 should theoretically perform just a bit faster than the GeForce GTX 260 Core 216 overall. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 2800 (3%)

Texel Rate

The GeForce GTX 260 Core 216 should be a small bit (more or less 18%) faster with regards to 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

If using high levels of AA is important to you, then the Radeon RX 550 is a better choice, not by a very large margin though. (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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
