Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 560 Ti comes with a GPU clock speed of 822 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1002 MHz through a 256-bit bus. It also features 384 SPUs, 64 TAUs, and 32 ROPs.
Compare all that to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular card. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 560 Ti should theoretically be much superior to the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe GeForce GTX 560 Ti is much (approximately 237%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is superior to the Radeon HD 6570 (OEM) 2GB, by far. (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 transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must 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 AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per 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 better 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
