Compare any two graphics cards:
Radeon HD 7990 vs Radeon Vega Frontier Edition
IntroThe Radeon HD 7990 has a GPU core clock speed of 950 MHz, and the 3072 MB of GDDR5 memory is set to run at 1500 MHz through a 384-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.Compare those specs to the Radeon Vega Frontier Edition, which has GPU clock speed of 1382 MHz, and 16384 MB of HBM2 RAM set to run at 1890 MHz through a 2048-bit bus. It also is made up of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7990 should in theory be a small bit superior to the Radeon Vega Frontier Edition in general. (explain)
Texel RateThe Radeon Vega Frontier Edition should be quite a bit (about 45%) faster with regards to AF than the Radeon HD 7990. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon Vega Frontier Edition is a better choice, and very much so. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
