Compare any two graphics cards:
GeForce GTX 285 1GB vs GeForce GTX 750 Ti
IntroThe GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 memory works at a frequency of 1242 MHz on this particular card. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare those specifications to the GeForce GTX 750 Ti, which features a core clock frequency of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 285 1GB should perform a lot faster than the GeForce GTX 750 Ti in general. (explain)
Texel RateThe GeForce GTX 285 1GB is a lot (approximately 27%) better at anisotropic filtering than the GeForce GTX 750 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 285 1GB is the winner, by far. (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 Comparison
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. Specifications
Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, 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 most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
