Radeon HD 5850 vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which comes with a clock speed of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5850 should be 700% quicker than the Radeon R5 M230 in general, due to its higher bandwidth. (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 (about 235%) more effective at anisotropic filtering than the Radeon R5 M230. (explain)

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

Pixel Rate

The Radeon HD 5850 will be a lot (about 644%) more effective at FSAA than the Radeon R5 M230, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are applied per second. This 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
