Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 465
IntroThe GeForce 9800 GX2 uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory runs at a speed of 1000 MHz on this particular model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare that to the GeForce GTX 465, which features a GPU core clock speed of 607 MHz, and 1024 MB of GDDR5 memory running at 802 MHz through a 256-bit bus. It also is comprised of 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 9800 GX2 should theoretically be a lot better than the GeForce GTX 465 overall. (explain)
Texel RateThe GeForce 9800 GX2 will be much (approximately 188%) better at anisotropic filtering than the GeForce GTX 465. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, not by a very large margin though. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
