GeForce GTX 880M vs Radeon RX 550

Intro

The GeForce GTX 880M features a GPU core speed of 954 MHz, and the 4096 MB of GDDR5 memory is set to run at 1000 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation 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 comprised of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
