Radeon RX 5500 vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which comes with a core clock speed of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also uses a 2048-bit memory bus, and makes use of a 14 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 64 ROPs.

Radeon RX 5500		146960 Mtexels/sec
	Difference: 111984 (76%)

Pixel Rate

The Radeon RX Vega 56 is a lot (approximately 38%) faster with regards to AA than the Radeon RX 5500, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 20544 (38%)

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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
