Radeon HD 5770 vs Radeon R9 M280X

Intro

The Radeon HD 5770 has a clock speed of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Compare those specs to the Radeon R9 M280X, which features a core clock speed of 900 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
