Compare any two graphics cards:
Radeon HD 7970 vs Radeon R9 290
IntroThe Radeon HD 7970 has a core clock frequency of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R9 290, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 512-bit bus, and makes use of a 28 nm design. It features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 290 should in theory be quite a bit faster than the Radeon HD 7970 overall. (explain)
Texel RateThe Radeon R9 290 will be just a bit (more or less 8%) faster with regards to AF than the Radeon HD 7970. (explain)
Pixel RateThe Radeon R9 290 is quite a bit (about 73%) faster with regards to full screen anti-aliasing than the Radeon HD 7970, and also will be able to handle higher screen 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
