GeForce GTX 980M vs Radeon RX 460


Intro

The GeForce GTX 980M has a GPU core clock speed of 1038 MHz, and the 4096 MB of GDDR5 RAM runs at 1000 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 Texture Address Units, and 64 Raster Operation Units.

Compare all that to the Radeon RX 460, which features core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the ability to get to the max fill rate.
