Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 has a core clock frequency of 550 MHz and a DDR2 memory speed of 500 MHz. It also features a 128-bit memory bus, and makes use of a 65 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.
Compare all that to the GeForce GT 210, which has a clock speed of 589 MHz and a DDR3 memory speed of 800 MHz. It also features a 64-bit bus, and uses a 40 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce 9500 GT DDR2 should theoretically be quite a bit superior to the GeForce GT 210 in general. (explain)
Texel RateThe GeForce 9500 GT DDR2 is quite a bit (more or less 87%) better at AF than the GeForce GT 210. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 9500 GT DDR2 is the winner, 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 (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. 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 ability to get to the maximum fill rate.
