Radeon R9 380 2G vs Radeon RX 5700

Intro

Compare all of that to the Radeon RX 5700, which features a GPU core clock speed of 1465 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Radeon R9 380 2G		190 Watts
	Difference: 10 Watts (6%)

Memory Bandwidth

The Radeon RX 5700, in theory, should be much faster than the Radeon R9 380 2G overall. (explain)

Radeon RX 5700		458752 MB/sec
Radeon R9 380 2G		182400 MB/sec
	Difference: 276352 (152%)

Texel Rate

The Radeon RX 5700 should be quite a bit (approximately 94%) better at AF than the Radeon R9 380 2G. (explain)

Radeon RX 5700		210960 Mtexels/sec
Radeon R9 380 2G		108640 Mtexels/sec
	Difference: 102320 (94%)

Pixel Rate

The Radeon RX 5700 should be quite a bit (more or less 202%) more effective at FSAA than the Radeon R9 380 2G, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon R9 380 2G		31040 Mpixels/sec
	Difference: 62720 (202%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
