Radeon HD 6750 vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which comes with GPU clock speed of 780 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Radeon R5 M230		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 is much (approximately 67%) faster with regards to AF than the Radeon R5 M230. (explain)

Radeon HD 6750		26100 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 10500 (67%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6750 is the winner, and very much so. (explain)

Radeon HD 6750		11600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 8480 (272%)

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 transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many 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.
