Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 has clock speeds of 550 MHz on the GPU, and 500 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.
Compare all that to the GeForce GT 210, which comes with GPU clock speed of 589 MHz, and 512 MB of DDR3 memory set to run at 800 MHz through a 64-bit bus. It also features 16 SPUs, 8 Texture Address Units, and 4 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 9500 GT DDR2 should theoretically perform much faster than the GeForce GT 210 overall. (explain)
Texel RateThe GeForce 9500 GT DDR2 is quite a bit (about 87%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 9500 GT DDR2 is a lot (more or less 87%) better at FSAA than the GeForce GT 210, and also will be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
