GeForce GTX 780 Ti vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has a clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit memory bus, and uses a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 780 Ti should be a small bit faster than the Radeon RX 5600 overall. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 41088 (14%)

Texel Rate

The GeForce GTX 780 Ti is just a bit (about 19%) better at anisotropic filtering than the Radeon RX 5600. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 34000 (19%)

Pixel Rate

The Radeon RX 5600 will be a lot (more or less 110%) more effective at FSAA than the GeForce GTX 780 Ti, and also should be able to handle higher screen resolutions better. (explain)

Radeon RX 5600		88000 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 46000 (110%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
