GeForce GTX 870M vs Radeon RX 560

Intro

The GeForce GTX 870M uses a 28 nm design. nVidia has set the core speed at 941 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular card. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

Compare that to the Radeon RX 560, which has a clock frequency of 1175 MHz and a GDDR5 memory speed of 7000 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It features 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
