Compare any two graphics cards:
Radeon HD 7970 vs Radeon R9 280
IntroThe Radeon HD 7970 comes with a clock frequency of 925 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 ROPs.Compare all of that to the Radeon R9 280, which features core speeds of 933 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 RAM. 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 BandwidthThe Radeon HD 7970 should in theory perform just a bit faster than the Radeon R9 280 in general. (explain)
Texel RateThe Radeon HD 7970 should be a bit (more or less 13%) faster with regards to anisotropic filtering than the Radeon R9 280. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 280 is a better choice, but it probably won't make a huge difference. (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 (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
