Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 makes use of a 40 nm design. nVidia has clocked the core frequency at 589 MHz. The DDR3 RAM runs at a speed of 800 MHz on this particular model. It features 16 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.
Compare those specifications to the Radeon HD 4650 1GB, which features a core clock speed of 600 MHz and a GDDR3 memory speed of 700 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 4650 1GB should perform much faster than the GeForce GT 210 in general. (explain)
Texel RateThe Radeon HD 4650 1GB will be much (more or less 307%) more effective at anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 4650 1GB will be quite a bit (more or less 104%) more effective at AA than the GeForce GT 210, and also will be capable of handling higher screen resolutions without losing too much performance. (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 max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling 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 card could possibly write to the 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
