Radeon R7 250X		72000 MB/sec
	Difference: 423411 (588%)

Texel Rate

The Radeon RX Vega 64 will be much (about 698%) better at texture filtering than the Radeon R7 250X. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 279232 (698%)

Pixel Rate

The Radeon RX Vega 64 is quite a bit (approximately 399%) more effective at anti-aliasing than the Radeon R7 250X, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 63808 (399%)

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 largest amount of data (measured 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 clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
