Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 comes with a GPU core clock speed of 589 MHz, and the 512 MB of DDR3 memory runs at 800 MHz through a 64-bit bus. It also is comprised of 16 SPUs, 8 Texture Address Units, and 4 ROPs.
Compare those specs to the Radeon HD 4650 1GB, which makes use of a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR3 memory works at a frequency of 700 MHz on this specific card. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 4650 1GB should in theory be much faster than the GeForce GT 210 in general. (explain)
Texel RateThe Radeon HD 4650 1GB is much (approximately 307%) better at AF than the GeForce GT 210. (explain)
Pixel RateIf running with 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.
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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
