Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 7870
IntroThe GeForce GTX 560 Ti comes with core 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 all of that to the Radeon HD 7870, which has core speeds of 1000 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7870 will be 20% quicker than the GeForce GTX 560 Ti overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 7870 should be quite a bit (approximately 52%) better at AF than the GeForce GTX 560 Ti. (explain)
Pixel RateThe Radeon HD 7870 is a lot (approximately 22%) faster with regards to AA than the GeForce GTX 560 Ti, and should be capable of handling 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
