Radeon HD 6750 vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which has a core clock frequency 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 features 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Radeon HD 6750		64000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 is quite a bit (more or less 67%) faster with regards to texture filtering than the Radeon R5 M230. (explain)

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

Pixel Rate

The Radeon HD 6750 will be a lot (more or less 272%) faster with regards to FSAA than the Radeon R5 M230, and capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
