GeForce GTX Titan Black vs Radeon RX 460 2GB

Intro

Compare that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this specific card. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 152320 (250%)

Pixel Rate

The GeForce GTX Titan Black is quite a bit (more or less 145%) faster with regards to FSAA than the Radeon RX 460 2GB, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 25232 (145%)

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 (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
