Radeon R9 M295X vs Radeon VII

Intro

Compare all that to the Radeon VII, which has a GPU core clock speed of 1400 MHz, and 16384 MB of HBM2 memory set to run at 1000 MHz through a 4096-bit bus. It also is comprised of 3840 SPUs, 240 Texture Address Units, and 64 ROPs.

Radeon VII		295 Watts
	Difference: 170 Watts (136%)

Memory Bandwidth

Theoretically speaking, the Radeon VII is 496% faster than the Radeon R9 M295X overall, due to its greater data rate. (explain)

Radeon VII		1048576 MB/sec
Radeon R9 M295X		176000 MB/sec
	Difference: 872576 (496%)

Texel Rate

The Radeon VII is much (more or less 250%) faster with regards to AF than the Radeon R9 M295X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 M295X		96000 Mtexels/sec
	Difference: 240000 (250%)

Pixel Rate

The Radeon VII will be much (approximately 273%) more effective at FSAA than the Radeon R9 M295X, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 65600 (273%)

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 get to the max fill rate.
