Radeon HD 5750 1GB vs Radeon R9 380X

Intro

The Radeon HD 5750 1GB comes with a GPU clock speed of 700 MHz, and the 1024 MB of GDDR5 memory is set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the Radeon R9 380X, which makes use of a 28 nm design. AMD has clocked the core speed at 970 MHz. The GDDR5 RAM works at a frequency of 1425 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
