Geforce GTX 780 vs Radeon RX 480

Intro

Compare all that to the Radeon RX 480, which makes use of a 14 nm design. AMD has clocked the core speed at 1120 MHz. The GDDR5 RAM runs at a speed of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 should be 10% quicker than the Radeon RX 480 overall, because of its greater bandwidth. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Geforce GTX 780 will be a small bit (more or less 3%) better at AF than the Radeon RX 480. (explain)

Geforce GTX 780		165696 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 4416 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 780 is the winner, but it probably won't make a huge difference. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 5584 (16%)

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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
