Compare any two graphics cards:
GeForce GTX Titan vs Radeon HD 3850 X2
IntroThe GeForce GTX Titan makes use of a 28 nm design. nVidia has set the core speed at 837 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this particular card. It features 2688 SPUs along with 224 TAUs and 48 Rasterization Operator Units.Compare those specs to the Radeon HD 3850 X2, which features GPU core speed of 668 MHz, and 512 MB of GDDR3 memory running at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce GTX Titan should in theory be much superior to the Radeon HD 3850 X2 overall. (explain)
Texel RateThe GeForce GTX Titan should be quite a bit (approximately 777%) more effective at anisotropic filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe GeForce GTX Titan should be quite a bit (more or less 88%) better at anti-aliasing than the Radeon HD 3850 X2, and should be capable of handling higher screen resolutions while still performing well. (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 moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, 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 most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
