Radeon R9 380 2G vs Radeon R9 M295X

Intro

The Radeon R9 380 2G makes use of a 28 nm design. AMD has clocked the core speed at 970 MHz. The GDDR5 memory is set to run at a speed of 1425 MHz on this model. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Compare those specs to the Radeon R9 M295X, which uses a 28 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 RAM works at a frequency of 1375 MHz on this specific model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
