Radeon R5 M230 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which has core speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should in theory be a lot better 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 (more or less 137%) more effective 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 running with high levels of AA is important to you, then the Radeon R9 M365X is a better choice, by a large margin. (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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
