Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 260
IntroThe GeForce 9500 GT DDR2 comes with a GPU core speed of 550 MHz, and the 256 MB of DDR2 RAM is set to run at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.
Compare all that to the GeForce GTX 260, which uses a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this particular model. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 260, in theory, should perform quite a bit faster than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce GTX 260 is 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 a lot (more or less 267%) better at full screen anti-aliasing than the GeForce 9500 GT DDR2, and should be capable of handling higher resolutions while still performing well. (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: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
