Geforce GTX 780 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM set to run at 1500 MHz through a 192-bit bus. It also is made up of 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		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 will be 2% quicker than the Geforce GTX 780 in general, due to its greater data rate. (explain)

Radeon RX 5600		294912 MB/sec
Geforce GTX 780		288384 MB/sec
	Difference: 6528 (2%)

Texel Rate

The Radeon RX 5600 should be just a bit (more or less 6%) more effective at texture filtering than the Geforce GTX 780. (explain)

Radeon RX 5600		176000 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 10304 (6%)

Pixel Rate

The Radeon RX 5600 should be much (approximately 112%) faster with regards to FSAA than the Geforce GTX 780, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5600		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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
