Radeon R9 M290X vs Radeon VII

Intro

Compare all that to the Radeon VII, which features clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 memory. It features 3840 SPUs as well as 240 TAUs and 64 ROPs.

Radeon R9 M290X		100 Watts
Radeon VII		295 Watts
	Difference: 195 Watts (195%)

Memory Bandwidth

Theoretically speaking, the Radeon VII is 583% faster than the Radeon R9 M290X in general, due to its higher bandwidth. (explain)

Radeon VII		1048576 MB/sec
Radeon R9 M290X		153600 MB/sec
	Difference: 894976 (583%)

Texel Rate

The Radeon VII is quite a bit (about 394%) faster with regards to texture filtering than the Radeon R9 M290X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 M290X		68000 Mtexels/sec
	Difference: 268000 (394%)

Pixel Rate

The Radeon VII should be much (approximately 229%) faster with regards to FSAA than the Radeon R9 M290X, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 62400 (229%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
