Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 6970
IntroThe GeForce GTX 560 Ti features core clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.
Compare that to the Radeon HD 6970, which comes with a core clock frequency of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 1536 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6970 should theoretically be a lot better than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe Radeon HD 6970 will be much (more or less 61%) faster with regards to anisotropic filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateThe Radeon HD 6970 will be a little bit (more or less 7%) better at FSAA than the GeForce GTX 560 Ti, and will be able to handle 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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 card can 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
