GeForce GTX 560 vs Radeon RX 480 4GB

Intro

Compare all of that to the Radeon RX 480 4GB, which has GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 4GB should be 79% quicker than the GeForce GTX 560 in general, due to its higher bandwidth. (explain)

Radeon RX 480 4GB		229376 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 101248 (79%)

Texel Rate

The Radeon RX 480 4GB should be quite a bit (more or less 256%) better at texture filtering than the GeForce GTX 560. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 115920 (256%)

Pixel Rate

The Radeon RX 480 4GB is a lot (more or less 38%) more effective at anti-aliasing than the GeForce GTX 560, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 480 4GB		35840 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 9920 (38%)

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 (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
