Radeon HD 7950 3GB vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core frequency at 780 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this model. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7950 3GB should be quite a bit faster than the Radeon R5 M230 in general. (explain)

Radeon HD 7950 3GB		240000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 224000 (1400%)

Texel Rate

The Radeon HD 7950 3GB should be a lot (about 474%) more effective at anisotropic filtering than the Radeon R5 M230. (explain)

Radeon HD 7950 3GB		89600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 74000 (474%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 7950 3GB is the winner, by far. (explain)

Radeon HD 7950 3GB		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: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
