Geforce GTX 690 vs Radeon RX 480

Intro

Compare those specifications to the Radeon RX 480, which makes use of a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

The Geforce GTX 690 should be quite a bit (more or less 45%) faster with regards to AF than the Radeon RX 480. (explain)

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

Pixel Rate

The Geforce GTX 690 should be much (approximately 63%) more effective at anti-aliasing than the Radeon RX 480, and should be able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 690		58560 Mpixels/sec
Radeon RX 480		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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling 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 video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
