Radeon RX 5700 vs Radeon RX 7900 XT

Intro

Compare those specs to the Radeon RX 7900 XT, which makes use of a 5 nm design. AMD has clocked the core frequency at 1500 MHz. The GDDR6 memory is set to run at a speed of 2500 MHz on this specific card. It features 5376 SPUs as well as 336 TAUs and 192 ROPs.

The Radeon RX 7900 XT will be quite a bit (about 139%) more effective at texture filtering than the Radeon RX 5700. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 293040 (139%)

Pixel Rate

The Radeon RX 7900 XT will be a lot (approximately 207%) better at AA than the Radeon RX 5700, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 194240 (207%)

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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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.
