Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 240 GDDR5
IntroThe GeForce 9500 GT 1GB GDDR3 features core speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.
Compare all that to the GeForce GT 240 GDDR5, which comes with a clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GT 240 GDDR5 should perform quite a bit faster than the GeForce 9500 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce GT 240 GDDR5 should be a lot (about 100%) more effective at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateBoth cards have the exact same pixel rate, so in theory they should perform equally good at at anti-aliasing, and be able to handle the same screen resolutions. (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 data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units 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 per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
