Radeon RX 5700 vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which uses a 14 nm design. AMD has set the core speed at 1156 MHz. The HBM2 memory works at a frequency of 1600 MHz on this particular card. It features 3584 SPUs as well as 224 Texture Address Units and 64 ROPs.

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

In theory, the Radeon RX 5700 is 9% quicker than the Radeon RX Vega 56 overall, because of its higher data rate. (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 (more or less 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 a high screen resolution is important to you, then the Radeon RX 5700 is superior to the Radeon RX Vega 56, by far. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
