Radeon HD 6950 2GB vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which makes use of a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this specific model. It features 320 SPUs along with 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 2GB should perform a lot faster than the Radeon R5 M230 in general. (explain)

Radeon HD 6950 2GB		160000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 144000 (900%)

Texel Rate

The Radeon HD 6950 2GB should be a lot (about 351%) more effective at AF than the Radeon R5 M230. (explain)

Radeon HD 6950 2GB		70400 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 54800 (351%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6950 2GB is the winner, and very much so. (explain)

Radeon HD 6950 2GB		25600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 22480 (721%)

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 (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
