Radeon R9 M385X vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which has a core clock speed of 1670 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 will be 139% faster than the Radeon R9 M385X in general, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 5500 will be much (more or less 139%) better at anisotropic filtering than the Radeon R9 M385X. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 85360 (139%)

Pixel Rate

The Radeon RX 5500 will be much (about 204%) better at full screen anti-aliasing than the Radeon R9 M385X, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 35840 (204%)

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 in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be applied in one second. This 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
