Radeon R9 M290X vs Radeon VII

Intro

Compare those specs to the Radeon VII, which makes use of a 7 nm design. AMD has clocked the core speed at 1400 MHz. The HBM2 memory is set to run at a speed of 1000 MHz on this particular card. It features 3840 SPUs as well as 240 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M290X		100 Watts
Radeon VII		295 Watts
	Difference: 195 Watts (195%)

Memory Bandwidth

As far as performance goes, the Radeon VII should in theory be a lot better than the Radeon R9 M290X overall. (explain)

Radeon VII		1048576 MB/sec
Radeon R9 M290X		153600 MB/sec
	Difference: 894976 (583%)

Texel Rate

The Radeon VII should be much (approximately 394%) more effective at texture filtering than the Radeon R9 M290X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 M290X		68000 Mtexels/sec
	Difference: 268000 (394%)

Pixel Rate

The Radeon VII will be quite a bit (about 229%) better at full screen anti-aliasing than the Radeon R9 M290X, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 62400 (229%)

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 transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, 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 card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
