Radeon R9 M385X vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which features a GPU core clock speed of 1717 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 5500 XT should in theory be much superior to the Radeon R9 M385X in general. (explain)

Radeon RX 5500 XT		229376 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 XT should be a lot (more or less 145%) more effective at anisotropic filtering than the Radeon R9 M385X. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 89496 (145%)

Pixel Rate

The Radeon RX 5500 XT is quite a bit (about 212%) better at FSAA than the Radeon R9 M385X, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 37344 (212%)

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 MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
