Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 features a GPU core speed of 589 MHz, and the 512 MB of DDR3 RAM is set to run at 800 MHz through a 64-bit bus. It also features 16 Stream Processors, 8 TAUs, and 4 ROPs.
Compare all that to the Radeon HD 4650 1GB, which features a GPU core clock speed of 600 MHz, and 1024 MB of GDDR3 memory set to run at 700 MHz through a 128-bit bus. It also features 320(64x5) Stream Processors, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 4650 1GB should perform a lot faster than the GeForce GT 210 overall. (explain)
Texel RateThe Radeon HD 4650 1GB is quite a bit (approximately 307%) more effective at anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4650 1GB is a better choice, and very much so. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
