Radeon R5 M230 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which has a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should perform a lot faster than the Radeon R5 M230 in general. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M365X will be a lot (approximately 137%) better at texture filtering than the Radeon R5 M230. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 21400 (137%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M365X is superior to the Radeon R5 M230, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 11680 (374%)

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 transported across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 the graphics card can possibly write to the local memory in a 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
