Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 5450
IntroThe GeForce GT 210 comes with core clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.
Compare that to the Radeon HD 5450, which features a core clock speed of 650 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and uses a 40 nm design. It is comprised of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe Radeon HD 5450 is a small bit (approximately 10%) more effective at texture filtering than the GeForce GT 210. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 5450 is superior to the GeForce GT 210, but it probably won't make a huge difference. (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 information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
