Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M395X should be 900% faster than the Radeon R5 M230 in general, due to its greater bandwidth. (explain)

Radeon R9 M395X		160000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 144000 (900%)

Texel Rate

The Radeon R9 M395X will be a lot (more or less 493%) faster with regards to texture filtering than the Radeon R5 M230. (explain)

Radeon R9 M395X		92544 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 76944 (493%)

Pixel Rate

The Radeon R9 M395X should be much (more or less 642%) faster with regards to AA than the Radeon R5 M230, and also capable of handling higher screen resolutions better. (explain)

Radeon R9 M395X		23136 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 20016 (642%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at 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 the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
