GeForce GTS 450 1GB		57728 MB/sec
	Difference: 171648 (297%)

Texel Rate

The Radeon RX 5500 XT should be much (more or less 503%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 126040 (503%)

Pixel Rate

The Radeon RX 5500 XT will be quite a bit (more or less 339%) more effective at AA than the GeForce GTS 450 1GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 42416 (339%)

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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 maximum fill rate.
