GeForce 825M vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which makes use of a 7 nm design. AMD has clocked the core frequency at 1400 MHz. The HBM2 memory works at a frequency of 1000 MHz on this specific card. It features 3840 SPUs along with 240 TAUs 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

As far as performance goes, the Radeon VII should in theory be quite a bit better than the GeForce 825M in general. (explain)

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

Texel Rate

The Radeon VII should be quite a bit (approximately 2371%) more effective at texture filtering than the GeForce 825M. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon VII is a better choice, by far. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
