Radeon HD 6750 1GB vs Radeon R9 380 2G
Intro
The Radeon HD 6750 1GB features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.Compare all of that to the Radeon R9 380 2G, which uses a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 memory works at a frequency of 1425 MHz on this model. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core 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 processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
