Geforce GTX 780 vs Radeon RX 580

Intro

Compare those specifications to the Radeon RX 580, which uses a 14 nm design. AMD has set the core frequency at 1257 MHz. The GDDR5 RAM runs at a frequency of 2000 MHz on this model. It features 2304 SPUs along with 144 Texture Address Units and 32 ROPs.

Radeon RX 580		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 580 should be just a bit (about 9%) more effective at AF than the Geforce GTX 780. (explain)

Radeon RX 580		181008 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 15312 (9%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 780 is the winner, but it probably won't make a huge difference. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 1200 (3%)

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 max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
