Geforce GTX 690 vs Radeon RX 480 4GB

Intro

Compare all of that to the Radeon RX 480 4GB, which uses a 14 nm design. AMD has clocked the core speed at 1120 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this specific card. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480 4GB		150 Watts
Geforce GTX 690		300 Watts
	Difference: 150 Watts (100%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 690 should be 68% quicker than the Radeon RX 480 4GB overall, due to its greater bandwidth. (explain)

Geforce GTX 690		384512 MB/sec
Radeon RX 480 4GB		229376 MB/sec
	Difference: 155136 (68%)

Texel Rate

The Geforce GTX 690 should be a lot (approximately 45%) better at anisotropic filtering than the Radeon RX 480 4GB. (explain)

Geforce GTX 690		234240 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 72960 (45%)

Pixel Rate

The Geforce GTX 690 is a lot (more or less 63%) more effective at full screen anti-aliasing than the Radeon RX 480 4GB, and should be able to handle higher screen resolutions better. (explain)

Geforce GTX 690		58560 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 22720 (63%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
