Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 comes with a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 128-bit bus, and uses a 65 nm design. It features 32 SPUs, 16 TAUs, and 8 ROPs.
Compare those specs to the GeForce GTX 650 Ti, which features a core clock frequency of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 650 Ti should in theory be much better than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce GTX 650 Ti is much (approximately 575%) more effective at texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 650 Ti is quite a bit (more or less 237%) better at AA than the GeForce 9500 GT DDR2, and also will be capable of handling higher resolutions better. (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 max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units 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 processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
