Compare any two graphics cards:
GeForce GTX 650 Ti vs Radeon HD 6790
IntroThe GeForce GTX 650 Ti makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this particular model. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon HD 6790, which has a clock frequency of 840 MHz and a GDDR5 memory speed of 1050 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6790 should in theory be quite a bit better than the GeForce GTX 650 Ti overall. (explain)
Texel RateThe GeForce GTX 650 Ti should be quite a bit (approximately 77%) better at AF than the Radeon HD 6790. (explain)
Pixel RateThe GeForce GTX 650 Ti will be a bit (approximately 10%) faster with regards to FSAA than the Radeon HD 6790, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 texture units of the card by the core clock 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
