Geforce GTX 780 vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which features a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
Geforce GTX 780		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 should perform a little bit faster than the Radeon RX 590 overall. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 590 should be much (about 28%) more effective at anisotropic filtering than the Geforce GTX 780. (explain)

Radeon RX 590		211536 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 45840 (28%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 590 is superior to the Geforce GTX 780, though only just barely. (explain)

Radeon RX 590		47008 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 5584 (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 max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many 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.
