GeForce GTX Titan Black vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which comes with clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

In theory, the GeForce GTX Titan Black should perform quite a bit faster than the Radeon RX 590 overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 73856 (28%)

Texel Rate

The GeForce GTX Titan Black is a little bit (approximately 1%) better at AF than the Radeon RX 590. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 1824 (1%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 590 is superior to the GeForce GTX Titan Black, though only just barely. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 4336 (10%)

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 data (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed in one second. This figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
