Radeon RX 5700 vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which comes with a clock speed of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also makes use of a 2048-bit bus, and uses a 14 nm design. It features 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Radeon RX Vega 56		210 Watts
	Difference: 30 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 should be 9% faster than the Radeon RX Vega 56 in general, because of its higher bandwidth. (explain)

Radeon RX 5700		458752 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 39322 (9%)

Texel Rate

The Radeon RX Vega 56 should be a lot (approximately 23%) more effective at texture filtering than the Radeon RX 5700. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 47984 (23%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 is superior to the Radeon RX Vega 56, by a large margin. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 19776 (27%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few 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.
