Geforce GTX 780 vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which has a GPU core clock speed of 1257 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 32 Raster Operation Units.

Memory Bandwidth

Theoretically, the Geforce GTX 780 should be just a bit faster than the Radeon RX 580 in general. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 580 should be a small bit (about 9%) better at texture filtering 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 lots of anti-aliasing 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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