GeForce GTX 880M vs Radeon RX 560

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 as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 memory works at a frequency of 7000 MHz on this particular model. It features 1024 SPUs along with 64 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 maximum fill rate.
