Compare any two graphics cards:
GeForce GTS 250 1GB vs GeForce GTX 650
IntroThe GeForce GTS 250 1GB has a GPU core clock speed of 738 MHz, and the 1024 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 650, which features a clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 650 should be 14% faster than the GeForce GTS 250 1GB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTS 250 1GB should be a lot (more or less 40%) faster with regards to texture filtering than the GeForce GTX 650. (explain)
Pixel RateIf running with high levels of AA 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 max amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
