Radeon HD 5750 1GB vs Radeon R9 M395X

Intro

The Radeon HD 5750 1GB has core speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 ROPs.

Compare all that to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has set 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 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
