Compare any two graphics cards:
Radeon HD 6750 1GB vs Radeon R9 270X
IntroThe Radeon HD 6750 1GB features a clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon R9 270X, which comes with GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1400 MHz through a 256-bit bus. It also features 1280 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270X should in theory be quite a bit faster than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe Radeon R9 270X will be much (approximately 207%) better at texture filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 270X is the winner, by a large margin. (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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
