Geforce GTX 780 vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which has a core clock frequency of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit memory bus, and makes use of a 7 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Geforce GTX 780		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT should be 19% faster than the Geforce GTX 780 in general, because of its greater bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
Geforce GTX 780		288384 MB/sec
	Difference: 55680 (19%)

Texel Rate

The Radeon RX 5600 XT should be a bit (more or less 19%) faster with regards to texture filtering than the Geforce GTX 780. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 32304 (19%)

Pixel Rate

The Radeon RX 5600 XT is a lot (approximately 112%) better at AA than the Geforce GTX 780, and will be able to handle higher screen resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 46576 (112%)

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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
