Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has set the core speed at 550 MHz. The DDR2 RAM works at a frequency of 500 MHz on this specific card. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.
Compare all that to the GeForce GT 210, which has GPU core speed of 589 MHz, and 512 MB of DDR3 RAM set to run at 800 MHz through a 64-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 9500 GT DDR2 will be 25% faster than the GeForce GT 210 in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce 9500 GT DDR2 should be quite a bit (approximately 87%) more effective at anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 9500 GT DDR2 should be much (more or less 87%) faster with regards to FSAA than the GeForce GT 210, and will be able to handle higher resolutions more effectively. (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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
