Compare any two graphics cards:
Geforce GTX 780 vs Radeon HD 7970
IntroThe Geforce GTX 780 comes with a core clock speed of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It features 2304 SPUs, 192 TAUs, and 48 ROPs.Compare those specifications to the Radeon HD 7970, which features core speeds of 925 MHz on the GPU, and 1375 MHz on the 3072 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe Geforce GTX 780 should theoretically perform a little bit faster than the Radeon HD 7970 overall. (explain)
Texel RateThe Geforce GTX 780 should be quite a bit (approximately 40%) better at anisotropic filtering than the Radeon HD 7970. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Geforce GTX 780 is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

have 2 7970's. Sapphire dual-x. See no reason to upgrade in the next few years. Donald Trump will have left office by then even if he does 2 terms.
