Geforce GTX 780 vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which comes with core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
Geforce GTX 780		250 Watts
	Difference: 170 Watts (213%)

Memory Bandwidth

Theoretically, the Geforce GTX 780 should be quite a bit faster than the Radeon RX 560 in general. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 173696 (151%)

Texel Rate

The Geforce GTX 780 is a lot (about 120%) more effective at AF than the Radeon RX 560. (explain)

Geforce GTX 780		165696 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 90496 (120%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 780 is a better choice, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 22624 (120%)

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 megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
