Radeon HD 5750 512MB vs Radeon R9 M390X

Intro

The Radeon HD 5750 512MB has a GPU core speed of 700 MHz, and the 512 MB of GDDR5 memory runs at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Compare those specifications to the Radeon R9 M390X, which uses a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
