Compare any two graphics cards:
Radeon HD 6750 vs Radeon R9 280X
IntroThe Radeon HD 6750 uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular card. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon R9 280X, which features a clock speed of 850 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 280X should be quite a bit faster than the Radeon HD 6750 overall. (explain)
Texel RateThe Radeon R9 280X is a lot (approximately 317%) faster with regards to AF than the Radeon HD 6750. (explain)
Pixel RateThe Radeon R9 280X should be quite a bit (about 134%) faster with regards to FSAA than the Radeon HD 6750, and able to handle higher resolutions more effectively. (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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
