Compare any two graphics cards:
GeForce 825M vs Radeon R7 M360
IntroThe GeForce 825M uses a 28 nm design. nVidia has clocked the core speed at 850 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this card. It features 384 SPUs along with 16 TAUs and 8 ROPs.
Compare those specs to the Radeon R7 M360, which uses a 28 nm design. AMD has set the core speed at 1125 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Performance-wise, the Radeon R7 M360 should theoretically be a little bit better than the GeForce 825M in general. (explain)
Texel RateThe Radeon R7 M360 will be quite a bit (about 99%) more effective at AF than the GeForce 825M. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R7 M360 is the winner, 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 (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
