Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 has a clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit memory bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.
Compare all of that to the Radeon HD 4650 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR3 RAM works at a frequency of 700 MHz on this card. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.

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 is quite a bit (approximately 307%) more effective 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, by far. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
