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 runs at 1375 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Compare those specifications to the Radeon RX 470, which features a clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also features a 256-bit bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
