Radeon R9 M380 vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which has a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 5500 should theoretically perform quite a bit faster than the Radeon R9 M380 overall. (explain)

Radeon RX 5500		229376 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 should be much (approximately 267%) more effective at anisotropic filtering than the Radeon R9 M380. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 106960 (267%)

Pixel Rate

The Radeon RX 5500 should be a lot (more or less 234%) faster with regards to AA than the Radeon R9 M380, and also should be able to handle higher resolutions more effectively. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 37440 (234%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
