Compare any two graphics cards:
GeForce GTX 465 vs Geforce GTX 780
IntroThe GeForce GTX 465 has a GPU core clock speed of 607 MHz, and the 1024 MB of GDDR5 RAM is set to run at 802 MHz through a 256-bit bus. It also features 352 Stream Processors, 44 Texture Address Units, and 32 ROPs.Compare those specifications to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory works at a speed of 1502 MHz on this specific model. It features 2304 SPUs as well as 192 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 780, in theory, should perform quite a bit faster than the GeForce GTX 465 overall. (explain)
Texel RateThe Geforce GTX 780 is much (approximately 520%) more effective at texture filtering than the GeForce GTX 465. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Geforce GTX 780 is superior to the GeForce GTX 465, 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses 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, 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 calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
