Radeon R9 M290X vs Radeon VII

Intro

Compare all of that to the Radeon VII, which comes with a clock frequency of 1400 MHz and a HBM2 memory speed of 1000 MHz. It also makes use of a 4096-bit memory bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 64 ROPs.

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

Texel Rate

The Radeon VII will be much (more or less 394%) more effective at anisotropic 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 should be much (approximately 229%) more effective at anti-aliasing than the Radeon R9 M290X, and will be capable of handling higher resolutions without slowing down too much. (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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
