Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 480 4GB
IntroThe Radeon HD 7970 uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this specific model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.Compare those specifications to the Radeon RX 480 4GB, which has a core clock frequency of 1120 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7970 should theoretically be a little bit better than the Radeon RX 480 4GB in general. (explain)
Texel RateThe Radeon RX 480 4GB is much (about 36%) faster with regards to AF than the Radeon HD 7970. (explain)
Pixel RateThe Radeon RX 480 4GB will be quite a bit (approximately 21%) better at full screen anti-aliasing than the Radeon HD 7970, and also will be able to handle higher screen resolutions without losing too much performance. (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 moved over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
