GeForce GTX Titan Black vs Radeon RX 480 4GB

Intro

Compare all that to the Radeon RX 480 4GB, which has GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 32 ROPs.

Radeon RX 480 4GB		150 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black will be 46% quicker than the Radeon RX 480 4GB in general, because of its greater bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon RX 480 4GB		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The GeForce GTX Titan Black should be a lot (approximately 32%) faster with regards to anisotropic filtering than the Radeon RX 480 4GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 52080 (32%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, but not by far. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 6832 (19%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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 number of Raster Operations Pipelines 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
