GeForce GTX 880M vs Radeon RX 550

Intro

The GeForce GTX 880M features clock speeds of 954 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 550, which has GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 TAUs, and 16 ROPs.

In theory, the GeForce GTX 880M will be 12% quicker than the Radeon RX 550 overall, because of its higher data rate. (explain)

GeForce GTX 880M 128000 MB/sec
Radeon RX 550 114688 MB/sec
Difference: 13312 (12%)

Texel Rate

The GeForce GTX 880M is a lot (approximately 247%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 880M 122112 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 86912 (247%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 880M is a better choice, and very much so. (explain)

GeForce GTX 880M 30528 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 12928 (73%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant 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.
