Radeon R9 380 4G vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which features a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Radeon R9 380 4G		182400 MB/sec
	Difference: 46976 (26%)

Texel Rate

The Radeon RX 5500 is quite a bit (more or less 35%) better at texture filtering than the Radeon R9 380 4G. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R9 380 4G		108640 Mtexels/sec
	Difference: 38320 (35%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 is a better choice, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R9 380 4G		31040 Mpixels/sec
	Difference: 22400 (72%)

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
