GeForce RTX 4090 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which has a core clock frequency of 1717 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and uses a 7 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

The GeForce RTX 4090 is quite a bit (more or less 657%) more effective at AF than the Radeon RX 5500 XT. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 993224 (657%)

Pixel Rate

The GeForce RTX 4090 should be much (about 616%) more effective at FSAA than the Radeon RX 5500 XT, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 4090		393360 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 338416 (616%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
