Nvidia Titan X vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which uses a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 memory works at a speed of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480		150 Watts
Nvidia Titan X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the Nvidia Titan X will be 88% faster than the Radeon RX 480 overall, due to its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 229376 (88%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 97%) more effective at AF than the Radeon RX 480. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 156128 (97%)

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is superior to the Radeon RX 480, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 100192 (280%)

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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
