GeForce GTX 480 vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which uses a 14 nm design. AMD has clocked the core frequency at 926 MHz. The GDDR5 RAM works at a frequency of 1650 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

GeForce GTX 480		177408 MB/sec
	Difference: 33792 (19%)

Texel Rate

The Radeon RX 470 4GB will be much (more or less 182%) better at anisotropic filtering than the GeForce GTX 480. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 76528 (182%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 480 is superior to the Radeon RX 470 4GB, though only just barely. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 3968 (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 information (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
