GeForce GTX 780 Ti vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which has GPU clock speed of 1090 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the GeForce GTX 780 Ti is 200% faster than the Radeon RX 460 2GB overall, because of its greater bandwidth. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 224000 (200%)

Texel Rate

The GeForce GTX 780 Ti is a lot (more or less 244%) faster with regards to texture filtering than the Radeon RX 460 2GB. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 148960 (244%)

Pixel Rate

The GeForce GTX 780 Ti should be much (approximately 141%) more effective at full screen anti-aliasing than the Radeon RX 460 2GB, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 24560 (141%)

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 information (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
