Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 makes use of a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR3 RAM works at a frequency of 800 MHz on this card. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.
Compare those specifications to the Radeon HD 4650 1GB, which comes with GPU clock speed of 600 MHz, and 1024 MB of GDDR3 memory running at 700 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 4650 1GB should in theory be much superior to the GeForce GT 210 in general. (explain)
Texel RateThe Radeon HD 4650 1GB should be much (more or less 307%) better at texture filtering than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 4650 1GB will be a lot (more or less 104%) better at full screen anti-aliasing than the GeForce GT 210, and also 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 information (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
