Radeon HD 5870 vs Radeon R7 M260X

Intro

The Radeon HD 5870 has a clock speed of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is made up of 1600(320x5) SPUs, 80 TAUs, and 32 Raster Operation Units.

Compare that to the Radeon R7 M260X, which features GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
