Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 has clock speeds of 550 MHz on the GPU, and 500 MHz on the 256 MB of DDR2 memory. It features 32 SPUs along with 16 TAUs and 8 ROPs.
Compare those specs to the GeForce GTX 650 Ti, which comes with GPU core speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 650 Ti will be 440% quicker than the GeForce 9500 GT DDR2 in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 650 Ti is quite a bit (about 575%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 650 Ti is superior to the GeForce 9500 GT DDR2, by a large margin. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at 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 record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
