Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon R7 240
IntroThe GeForce GTX 560 Ti uses a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM runs at a speed of 1002 MHz on this specific model. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.
Compare those specifications to the Radeon R7 240, which makes use of a 28 nm design. AMD has clocked the core speed at 730 MHz. The DDR3 memory runs at a speed of 900 MHz on this particular card. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti should perform a lot faster than the Radeon R7 240 overall. (explain)
Texel RateThe GeForce GTX 560 Ti should be a lot (approximately 260%) faster with regards to anisotropic filtering than the Radeon R7 240. (explain)
Pixel RateThe GeForce GTX 560 Ti is a lot (approximately 350%) better at anti-aliasing than the Radeon R7 240, and also capable of handling higher resolutions without losing too much performance. (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 moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
