Compare any two graphics cards:
GeForce GTX 970 vs Radeon HD 4850 X2 1GB
IntroThe GeForce GTX 970 has a GPU core speed of 1050 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 256-bit bus. It also is made up of 1664 Stream Processors, 104 TAUs, and 64 Raster Operation Units.Compare all of that to the Radeon HD 4850 X2 1GB, which uses a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 memory runs at a speed of 993 MHz on this card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 should be 76% quicker than the Radeon HD 4850 X2 1GB in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 970 will be quite a bit (more or less 118%) faster with regards to AF than the Radeon HD 4850 X2 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 970 is the winner, 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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
