Compare any two graphics cards:
Radeon HD 7990 vs Radeon R9 Nano
IntroThe Radeon HD 7990 uses a 28 nm design. AMD has clocked the core frequency at 950 MHz. The GDDR5 memory is set to run at a speed of 1500 MHz on this specific model. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.Compare those specifications to the Radeon R9 Nano, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The HBM RAM is set to run at a frequency of 500 MHz on this card. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7990 should in theory be a little bit superior to the Radeon R9 Nano overall. (explain)
Texel RateThe Radeon R9 Nano should be a little bit (approximately 5%) better at anisotropic filtering than the Radeon HD 7990. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 Nano is the winner, but not by far. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
