GeForce GTX 560 Ti vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which comes with a GPU core clock speed of 926 MHz, and 4096 MB of GDDR5 RAM set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

GeForce GTX 560 Ti		128256 MB/sec
	Difference: 82944 (65%)

Texel Rate

The Radeon RX 470 4GB is much (about 125%) faster with regards to AF than the GeForce GTX 560 Ti. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 560 Ti		52608 Mtexels/sec
	Difference: 65920 (125%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 470 4GB is superior to the GeForce GTX 560 Ti, not by a very large margin though. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GTX 560 Ti		26304 Mpixels/sec
	Difference: 3328 (13%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
