Radeon R7 250 vs Radeon VII

Intro

Compare all of that to the Radeon VII, which features GPU core speed of 1400 MHz, and 16384 MB of HBM2 memory set to run at 1000 MHz through a 4096-bit bus. It also is made up of 3840 SPUs, 240 Texture Address Units, and 64 ROPs.

Memory Bandwidth

Theoretically, the Radeon VII should perform quite a bit faster than the Radeon R7 250 in general. (explain)

Radeon VII		1048576 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 974976 (1325%)

Texel Rate

The Radeon VII should be quite a bit (approximately 1300%) better at texture filtering than the Radeon R7 250. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 312000 (1300%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon VII is a better choice, and very much so. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 81600 (1020%)

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 max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
