Radeon R7 260X vs Radeon R9 380 4G

Intro

The Radeon R7 260X features a core clock speed of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Compare all of that to the Radeon R9 380 4G, which has GPU core speed of 970 MHz, and 4096 MB of GDDR5 RAM running at 1425 MHz through a 256-bit bus. It also is made up of 1792 Stream Processors, 112 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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