Radeon R9 270X		179200 MB/sec
	Difference: 869376 (485%)

Texel Rate

The Radeon VII is quite a bit (more or less 320%) better at texture filtering than the Radeon R9 270X. (explain)

Radeon VII		336000 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 256000 (320%)

Pixel Rate

The Radeon VII should be a lot (about 180%) more effective at full screen anti-aliasing than the Radeon R9 270X, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon VII		89600 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 57600 (180%)

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 data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 max fill rate.
