GeForce GTX 880M vs Radeon RX 460


Intro

The GeForce GTX 880M comes with a clock speed of 954 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Compare that to the Radeon RX 460, which comes with a core clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
