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 frequency at 589 MHz. The DDR3 memory runs at a frequency of 800 MHz on this specific card. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.
Compare all that to the Radeon HD 4350, which makes use of a 55 nm design. AMD has clocked the core frequency at 575 MHz. The DDR2 RAM works at a frequency of 500 MHz on this card. 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)
The GeForce GT 210 should in theory perform much faster than the Radeon HD 4350 overall. (explain)
Texel RateThe GeForce GT 210 should be just a bit (more or less 2%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)
Pixel RateThe GeForce GT 210 is a little bit (about 2%) more effective at FSAA than the Radeon HD 4350, and also capable of handling higher screen resolutions without slowing down too much. (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 MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
