Radeon R9 M295X vs Radeon VII

Intro

Compare all that to the Radeon VII, which features GPU 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 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M295X		125 Watts
Radeon VII		295 Watts
	Difference: 170 Watts (136%)

Memory Bandwidth

In theory, the Radeon VII should be 496% faster than the Radeon R9 M295X in general, due to its higher data rate. (explain)

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

Texel Rate

The Radeon VII should be quite a bit (more or less 250%) better 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 a better choice, by a large margin. (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 largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 this number, the better the video 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 per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
