Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GTS 150
IntroThe GeForce 9500 GT 512MB GDDR3 has a GPU core speed of 550 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.Compare all that to the GeForce GTS 150, which features a clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 150 should in theory be much faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GTS 150 is quite a bit (more or less 438%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTS 150 is the winner, by a large margin. (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 (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
