Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 260
IntroThe GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has set the core speed at 550 MHz. The DDR2 RAM is set to run at a speed of 500 MHz on this card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 260, which features a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 memory set to run at 999 MHz through a 448-bit bus. It also features 192 Stream Processors, 64 TAUs, and 28 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 260 should be a lot faster than the GeForce 9500 GT DDR2 in general. (explain)
Texel RateThe GeForce GTX 260 will be quite a bit (approximately 319%) faster with regards to texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 260 should be quite a bit (more or less 267%) more effective at full screen anti-aliasing than the GeForce 9500 GT DDR2, and also should be capable of handling higher resolutions more effectively. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 max fill rate.
