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 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 1280 SPUs as well as 80 Texture Address Units and 48 ROPs.

Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
