Radeon R9 M295X vs Radeon RX 470

Intro

The Radeon R9 M295X comes with a GPU clock speed of 750 MHz, and the 4096 MB of GDDR5 memory is set to run at 1375 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon RX 470, which has core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
