Compare any two graphics cards:
Radeon HD 7970 vs Radeon R9 390 8G
IntroThe Radeon HD 7970 makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory works at a frequency of 1375 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.Compare those specs to the Radeon R9 390 8G, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390 8G should be quite a bit faster than the Radeon HD 7970 in general. (explain)
Texel RateThe Radeon R9 390 8G should be much (approximately 35%) faster with regards to anisotropic filtering than the Radeon HD 7970. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 390 8G is the winner, by a large margin. (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 (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
