Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 650 Ti 2GB
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 memory works at a speed of 902 MHz on this card. It features 192 SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare that to the GeForce GTX 650 Ti 2GB, which features clock speeds of 928 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 650 Ti 2GB should in theory be quite a bit better than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB should be a lot (about 137%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 650 Ti 2GB is the winner, though only just barely. (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 (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
