Radeon R9 M280X vs Radeon VII

Intro

Compare all that to the Radeon VII, which features a core clock speed of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also features a 4096-bit bus, and uses a 7 nm design. It is made up of 3840 SPUs, 240 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M280X		75 Watts
Radeon VII		295 Watts
	Difference: 220 Watts (293%)

Memory Bandwidth

Theoretically speaking, the Radeon VII will be 1092% faster than the Radeon R9 M280X overall, due to its greater bandwidth. (explain)

Radeon VII		1048576 MB/sec
Radeon R9 M280X		88000 MB/sec
	Difference: 960576 (1092%)

Texel Rate

The Radeon VII will be quite a bit (approximately 567%) more effective at AF than the Radeon R9 M280X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 285600 (567%)

Pixel Rate

The Radeon VII will be much (more or less 522%) faster with regards to FSAA than the Radeon R9 M280X, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 75200 (522%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per 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 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
