GeForce 825M vs Radeon VII

Intro

Compare those specifications 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 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M		33 Watts
Radeon VII		295 Watts
	Difference: 262 Watts (794%)

Memory Bandwidth

In theory, the Radeon VII should be 7182% quicker than the GeForce 825M in general, because of its higher bandwidth. (explain)

Radeon VII		1048576 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 1034176 (7182%)

Texel Rate

The Radeon VII will be much (more or less 2371%) better at anisotropic filtering than the GeForce 825M. (explain)

Radeon VII		336000 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 322400 (2371%)

Pixel Rate

The Radeon VII should be a lot (approximately 1218%) more effective at AA than the GeForce 825M, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon VII		89600 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 82800 (1218%)

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 information (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
