GeForce GTX 650 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has clocked the core speed at 1717 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this particular card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

GeForce GTX 650		64 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 66 Watts (103%)

Memory Bandwidth

Theoretically, the Radeon RX 5500 XT should perform much faster than the GeForce GTX 650 overall. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 149376 (187%)

Texel Rate

The Radeon RX 5500 XT is a lot (approximately 346%) more effective at texture filtering than the GeForce GTX 650. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 117240 (346%)

Pixel Rate

The Radeon RX 5500 XT will be quite a bit (about 225%) better at AA than the GeForce GTX 650, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 38016 (225%)

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 transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
