Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 260
IntroThe GeForce 9500 GT DDR2 makes use of 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 particular model. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.
Compare those specs to the GeForce GTX 260, which features a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 RAM set to run at 999 MHz through a 448-bit bus. It also is comprised of 192 SPUs, 64 TAUs, and 28 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 260 should in theory be quite a bit superior to the GeForce 9500 GT DDR2 in general. (explain)
Texel RateThe GeForce GTX 260 should be a lot (more or less 319%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 260 should be a lot (approximately 267%) faster with regards to AA than the GeForce 9500 GT DDR2, and should be capable of handling higher resolutions without slowing down too much. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, 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 card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
