Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4350
IntroThe GeForce GT 210 makes use of a 40 nm design. nVidia has set the core speed at 589 MHz. The DDR3 memory is set to run at a speed of 800 MHz on this model. It features 16 SPUs along with 8 TAUs and 4 ROPs.
Compare those specs to the Radeon HD 4350, which makes use of a 55 nm design. AMD has set the core speed at 575 MHz. The DDR2 RAM is set to run at a frequency of 500 MHz on this particular model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 210 should theoretically be a lot better than the Radeon HD 4350 in general. (explain)
Texel RateThe GeForce GT 210 should be just a bit (about 2%) better at AF than the Radeon HD 4350. (explain)
Pixel RateThe GeForce GT 210 is a small bit (approximately 2%) more effective at FSAA than the Radeon HD 4350, and also will be able to handle 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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
