Radeon RX 5500 vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which features core speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 memory. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Radeon RX 5500		150 Watts
Radeon RX Vega 64		295 Watts
	Difference: 145 Watts (97%)

Memory Bandwidth

In theory, the Radeon RX Vega 64 should be 116% quicker than the Radeon RX 5500 overall, because of its greater bandwidth. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 266035 (116%)

Texel Rate

The Radeon RX Vega 64 should be much (about 117%) better at AF than the Radeon RX 5500. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 172272 (117%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX Vega 64 is the winner, by far. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 26368 (49%)

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 (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 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 AA, HDR and higher screen resolutions.

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

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