GeForce GTX Titan Black vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which has a core clock frequency of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit bus, and uses a 12 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

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 will be 28% faster than the Radeon RX 590 in general, due to its greater data rate. (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 bit (more or less 1%) more effective 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

The Radeon RX 590 should be a small bit (about 10%) better at AA than the GeForce GTX Titan Black, and will be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (measured in 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 the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
