Geforce GTX 680 vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
Geforce GTX 680		195 Watts
	Difference: 120 Watts (160%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 680 should perform quite a bit faster than the Radeon RX 460 2GB in general. (explain)

Geforce GTX 680		192256 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 80256 (72%)

Texel Rate

The Geforce GTX 680 should be a lot (about 111%) better at texture filtering than the Radeon RX 460 2GB. (explain)

Geforce GTX 680		128768 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 67728 (111%)

Pixel Rate

The Geforce GTX 680 should be quite a bit (more or less 85%) faster with regards to AA than the Radeon RX 460 2GB, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Geforce GTX 680		32192 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 14752 (85%)

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 data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
