Radeon RX 5600 XT vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which comes with a core clock frequency of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also features a 2048-bit bus, and uses a 14 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon RX Vega 64		295 Watts
	Difference: 135 Watts (84%)

Memory Bandwidth

In theory, the Radeon RX Vega 64 will be 44% quicker than the Radeon RX 5600 XT in general, because of its higher data rate. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 151347 (44%)

Texel Rate

The Radeon RX Vega 64 will be a lot (about 61%) faster with regards to AF than the Radeon RX 5600 XT. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 121232 (61%)

Pixel Rate

The Radeon RX 5600 XT should be just a bit (more or less 10%) better at full screen anti-aliasing than the Radeon RX Vega 64, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 8192 (10%)

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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
