Compare any two graphics cards:
GeForce GTX 950 vs Radeon HD 4850 X2 512MB
IntroThe GeForce GTX 950 uses a 28 nm design. nVidia has set the core speed at 1024 MHz. The GDDR5 RAM runs at a frequency of 1652 MHz on this model. It features 768 SPUs as well as 48 TAUs and 32 ROPs.Compare those specifications to the Radeon HD 4850 X2 512MB, which has a core clock frequency of 625 MHz and a GDDR3 memory frequency of 993 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 X2 512MB should theoretically be a bit faster than the GeForce GTX 950 in general. (explain)
Texel RateThe Radeon HD 4850 X2 512MB should be just a bit (approximately 2%) faster with regards to anisotropic filtering than the GeForce GTX 950. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 950 is a better choice, 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 (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 maximum amount of pixels that the graphics card could possibly record to the local memory in one 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
