Compare any two graphics cards:
Radeon HD 6750 1GB vs Radeon R9 M265X
IntroThe Radeon HD 6750 1GB features core 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 that to the Radeon R9 M265X, which comes with a GPU core clock speed of 575 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M265X will be 13% quicker than the Radeon HD 6750 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 6750 1GB is just a bit (approximately 13%) better at anisotropic filtering than the Radeon R9 M265X. (explain)
Pixel RateThe Radeon HD 6750 1GB is much (more or less 26%) better at anti-aliasing than the Radeon R9 M265X, and should be able to handle higher resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 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.
