Radeon RX 5600 XT vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 RAM runs at a frequency of 1890 MHz on this specific model. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

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 should be 44% faster than the Radeon RX 5600 XT overall, due to its higher bandwidth. (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 much (more or less 61%) better at texture filtering 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 a small bit (about 10%) faster with regards to AA than the Radeon RX Vega 64, and able to handle higher resolutions without slowing down too much. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
