GeForce GTX 650 vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which comes with clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2304 SPUs as well as 144 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 96 Watts (150%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT should be much faster than the GeForce GTX 650 in general. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 264064 (330%)

Texel Rate

The Radeon RX 5600 XT should be much (approximately 485%) more effective at AF than the GeForce GTX 650. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 164144 (485%)

Pixel Rate

The Radeon RX 5600 XT is a lot (approximately 420%) better at anti-aliasing than the GeForce GTX 650, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 71072 (420%)

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 max amount of data (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many 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.
