Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GT 210
IntroThe GeForce 8400 GS 512MB features core clock speeds of 650 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.
Compare all that to the GeForce GT 210, which uses a 40 nm design. nVidia has clocked the core frequency at 589 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this specific model. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GT 210 will be 100% faster than the GeForce 8400 GS 512MB overall, because of its greater data rate. (explain)
Texel RateThe GeForce 8400 GS 512MB should be a small bit (approximately 10%) more effective at AF than the GeForce GT 210. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 8400 GS 512MB is a better choice, but only just. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
