GeForce GTX 970M vs Radeon RX 550

Intro

The GeForce GTX 970M uses a 28 nm design. nVidia has set the core frequency at 924 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this card. It features 1280 SPUs along with 80 TAUs and 48 Rasterization Operator Units.

Compare that to the Radeon RX 550, which features GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

GeForce GTX 970M 96000 MB/sec
Difference: 18688 (19%)

Texel Rate

The GeForce GTX 970M will be quite a bit (more or less 110%) better at AF than the Radeon RX 550. (explain)

GeForce GTX 970M 73920 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 38720 (110%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 970M is the winner, by far. (explain)

GeForce GTX 970M 44352 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 26752 (152%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 are applied per second. This number is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
