Radeon R9 270 vs Radeon R9 M295X

Intro

The Radeon R9 270 comes with a GPU core clock speed of 900 MHz, and the 2048 MB of GDDR5 RAM runs at 1400 MHz through a 256-bit bus. It also is made up of 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon R9 M295X, which comes with core clock speeds of 750 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
