Compare any two graphics cards:
GeForce GTX 465 vs GeForce GTX 650
IntroThe GeForce GTX 465 has core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 memory. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.Compare those specs to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core speed at 1058 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 465 should theoretically be quite a bit faster than the GeForce GTX 650 in general. (explain)
Texel RateThe GeForce GTX 650 should be much (about 27%) faster with regards to texture filtering than the GeForce GTX 465. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 465 is superior to the GeForce GTX 650, not by a very large margin though. (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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
