GeForce GTX 660 Ti vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1717 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this specific model. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

GeForce GTX 660 Ti		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5500 XT should theoretically be a lot better than the GeForce GTX 660 Ti in general. (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 should be quite a bit (about 47%) more effective at AF 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

If running with a high resolution is important to you, then the Radeon RX 5500 XT is a better choice, and very much so. (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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to get to the max fill rate.
