Radeon HD 5850 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which uses a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 memory works at a frequency of 1000 MHz on this card. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 5850 should perform quite a bit faster than the Radeon R5 M230 overall. (explain)

Radeon HD 5850		128000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 112000 (700%)

Texel Rate

The Radeon HD 5850 will be much (approximately 235%) more effective at AF than the Radeon R5 M230. (explain)

Radeon HD 5850		52200 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 36600 (235%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 5850 is superior to the Radeon R5 M230, and very much so. (explain)

Radeon HD 5850		23200 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 20080 (644%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. 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 quite a few 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.
