Geforce GTX 780 vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which makes use of a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units 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 bit faster than the Radeon RX 590 in general. (explain)

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

Texel Rate

The Radeon RX 590 is much (approximately 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, but not by far. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one 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. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
