Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X		125 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 110 Watts (88%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT 50th Anniversary Edition should be 187% faster than the Radeon R9 M395X overall, due to its greater data rate. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon R9 M395X		160000 MB/sec
	Difference: 298752 (187%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be quite a bit (about 190%) faster with regards to AF than the Radeon R9 M395X. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon R9 M395X		92544 Mtexels/sec
	Difference: 176256 (190%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be a lot (more or less 365%) more effective at anti-aliasing than the Radeon R9 M395X, and also will be able to handle higher screen resolutions better. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 84384 (365%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 one second.

Pixel Rate: Pixel rate is the most pixels the video card can 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
