Radeon R9 M295X vs Radeon VII

Intro

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

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

Texel Rate

The Radeon VII should be much (more or less 250%) more effective at anisotropic filtering than the Radeon R9 M295X. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon VII is superior to the Radeon R9 M295X, by far. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
