GeForce GTX 660 Ti vs Radeon RX 5500 XT

Intro

Compare those specifications 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 card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

Theoretically, the Radeon RX 5500 XT should perform much faster than the GeForce GTX 660 Ti overall. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 85376 (59%)

Texel Rate

The Radeon RX 5500 XT will be a lot (more or less 47%) more effective at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 48616 (47%)

Pixel Rate

The Radeon RX 5500 XT will be quite a bit (more or less 150%) better at anti-aliasing than the GeForce GTX 660 Ti, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 32984 (150%)

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 (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 ability to get to the maximum fill rate.
