Radeon R9 290X vs Radeon RX 460 2GB

Intro

The Radeon R9 290X has a GPU core speed of 800 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1250 MHz through a 512-bit bus. It also is made up of 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 460 2GB, which has a clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It features 896 SPUs, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of 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.
