Radeon R5 M230		16000 MB/sec
	Difference: 368000 (2300%)

Texel Rate

The Radeon R9 390X 8G will be quite a bit (more or less 1085%) faster with regards to anisotropic filtering than the Radeon R5 M230. (explain)

Radeon R9 390X 8G		184800 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 169200 (1085%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 390X 8G is superior to the Radeon R5 M230, and very much so. (explain)

Radeon R9 390X 8G		67200 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 64080 (2054%)

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 information (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied in one second. This is calculated by multiplying the total texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant 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.
