Compare any two graphics cards:
Radeon HD 7970 vs Radeon R9 280
IntroThe Radeon HD 7970 makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM is set to run at a frequency of 1375 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.Compare those specifications to the Radeon R9 280, which uses a 28 nm design. AMD has set the core frequency at 933 MHz. The GDDR5 memory works at a speed of 1250 MHz on this specific card. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthTheoretically speaking, the Radeon HD 7970 will be 10% faster than the Radeon R9 280 in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 7970 will be just a bit (more or less 13%) more effective at anisotropic filtering than the Radeon R9 280. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 280 is superior to the Radeon HD 7970, though only just barely. (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 (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out 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 it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be applied in one second. This is worked out by multiplying the total number of texture units by the core 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 one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
