Radeon HD 5670 vs Radeon R9 M290X

Intro

The Radeon HD 5670 uses a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific model. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Compare those specifications to the Radeon R9 M290X, which uses a 28 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM works at a speed of 1200 MHz on this card. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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