Compare any two graphics cards:
Geforce GTX 770 vs Radeon HD 3850 X2
IntroThe Geforce GTX 770 makes use of a 28 nm design. nVidia has set the core speed at 1046 MHz. The GDDR5 RAM is set to run at a frequency of 1753 MHz on this particular model. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 3850 X2, which features a clock frequency of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Geforce GTX 770 should perform a lot faster than the Radeon HD 3850 X2 in general. (explain)
Texel RateThe Geforce GTX 770 will be a lot (more or less 526%) faster with regards to AF than the Radeon HD 3850 X2. (explain)
Pixel RateThe Geforce GTX 770 will be much (approximately 57%) better at FSAA than the Radeon HD 3850 X2, and able to handle higher screen resolutions without losing too much performance. (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

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
