Radeon RX 5700 vs Radeon Vega Frontier Edition

Intro

Compare those specifications to the Radeon Vega Frontier Edition, which has a clock frequency of 1382 MHz and a HBM2 memory speed of 1890 MHz. It also makes use of a 2048-bit bus, and makes use of a 14 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Radeon Vega Frontier Edition		300 Watts
	Difference: 120 Watts (67%)

Memory Bandwidth

In theory, the Radeon Vega Frontier Edition should perform just a bit faster than the Radeon RX 5700 overall. (explain)

Radeon Vega Frontier Edition		495452 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 36700 (8%)

Texel Rate

The Radeon Vega Frontier Edition is quite a bit (approximately 68%) more effective at texture filtering than the Radeon RX 5700. (explain)

Radeon Vega Frontier Edition		353792 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 142832 (68%)

Pixel Rate

The Radeon RX 5700 should be a bit (about 6%) better at FSAA than the Radeon Vega Frontier Edition, and also will be able to handle higher screen resolutions better. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon Vega Frontier Edition		88448 Mpixels/sec
	Difference: 5312 (6%)

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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
