Radeon R7 250X 2GB		95 Watts
Radeon Vega Frontier Edition		300 Watts
	Difference: 205 Watts (216%)

Memory Bandwidth

In theory, the Radeon Vega Frontier Edition is 588% quicker than the Radeon R7 250X 2GB overall, because of its greater data rate. (explain)

Radeon Vega Frontier Edition		495452 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 423452 (588%)

Texel Rate

The Radeon Vega Frontier Edition is a lot (about 784%) more effective at AF than the Radeon R7 250X 2GB. (explain)

Radeon Vega Frontier Edition		353792 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 313792 (784%)

Pixel Rate

The Radeon Vega Frontier Edition will be a lot (more or less 453%) faster with regards to anti-aliasing than the Radeon R7 250X 2GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon Vega Frontier Edition		88448 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 72448 (453%)

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 max amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
