Radeon R9 M270X vs Radeon VII

Intro

Compare that to the Radeon VII, which makes use of a 7 nm design. AMD has set the core speed at 1400 MHz. The HBM2 memory runs at a speed of 1000 MHz on this particular model. It features 3840 SPUs along with 240 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon VII, in theory, should perform quite a bit faster than the Radeon R9 M270X overall. (explain)

Radeon VII		1048576 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 976576 (1356%)

Texel Rate

The Radeon VII will be a lot (approximately 1059%) more effective at AF than the Radeon R9 M270X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 307000 (1059%)

Pixel Rate

The Radeon VII is much (approximately 672%) better at anti-aliasing than the Radeon R9 M270X, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 78000 (672%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at 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 the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
