Compare any two graphics cards:
GeForce GTX 650 vs Radeon HD 6750 1GB
IntroThe GeForce GTX 650 has a clock frequency of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 6750 1GB, which comes with a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 650 should perform quite a bit faster than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe GeForce GTX 650 is much (about 30%) better at texture filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 650 is the winner, and very much so. (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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
