Radeon RX 5500 XT		229376 MB/sec
GeForce 8400 GS 512MB		6400 MB/sec
	Difference: 222976 (3484%)

Texel Rate

The Radeon RX 5500 XT should be a lot (about 2806%) faster with regards to texture filtering than the GeForce 8400 GS 512MB. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce 8400 GS 512MB		5200 Mtexels/sec
	Difference: 145896 (2806%)

Pixel Rate

The Radeon RX 5500 XT should be a lot (approximately 2013%) more effective at AA than the GeForce 8400 GS 512MB, and able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce 8400 GS 512MB		2600 Mpixels/sec
	Difference: 52344 (2013%)

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 data (in units of megabytes 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 the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
