Radeon RX 5500 XT vs Radeon RX Vega 64

Intro

Compare that to the Radeon RX Vega 64, which features a clock speed of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also features a 2048-bit memory bus, and uses a 14 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon RX Vega 64		295 Watts
	Difference: 165 Watts (127%)

Memory Bandwidth

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

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

Texel Rate

The Radeon RX Vega 64 should be much (about 111%) faster with regards to AF than the Radeon RX 5500 XT. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 168136 (111%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX Vega 64 is the winner, and very much so. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 24864 (45%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
