Radeon HD 7770 vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which comes with a core clock frequency of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also features a 192-bit bus, and uses a 7 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

Radeon HD 7770		72000 MB/sec
	Difference: 272064 (378%)

Texel Rate

The Radeon RX 5600 XT is quite a bit (more or less 395%) more effective at AF than the Radeon HD 7770. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon HD 7770		40000 Mtexels/sec
	Difference: 158000 (395%)

Pixel Rate

The Radeon RX 5600 XT will be a lot (approximately 450%) faster with regards to AA than the Radeon HD 7770, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon HD 7770		16000 Mpixels/sec
	Difference: 72000 (450%)

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 information (counted in megabytes per second) that can be transported across 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 DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, 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 most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
