Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4550 512MB
IntroThe GeForce GT 210 features clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs along with 8 TAUs and 4 ROPs.
Compare that to the Radeon HD 4550 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 600 MHz. The GDDR3 memory runs at a speed of 800 MHz on this specific model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe Radeon HD 4550 512MB should be a small bit (more or less 2%) faster with regards to AF than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 4550 512MB should be a little bit (more or less 2%) more effective at AA than the GeForce GT 210, and will be able to handle higher resolutions better. (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 megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
