Radeon R9 M265X vs Radeon VII

Intro

Compare all that to the Radeon VII, which has GPU core speed of 1400 MHz, and 16384 MB of HBM2 RAM set to run at 1000 MHz through a 4096-bit bus. It also is comprised of 3840 Stream Processors, 240 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon VII should be 1356% faster than the Radeon R9 M265X in general, due to its greater data rate. (explain)

Radeon VII		1048576 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 976576 (1356%)

Texel Rate

The Radeon VII should be quite a bit (more or less 1361%) faster with regards to texture filtering than the Radeon R9 M265X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 313000 (1361%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon VII is superior to the Radeon R9 M265X, and very much so. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 80400 (874%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 are processed in one second. This figure is worked out by multiplying the total number 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 amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
