Radeon HD 7950 3GB vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular card. It features 320 SPUs as well as 20 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 7950 3GB, in theory, should perform quite a bit faster than the Radeon R5 M230 overall. (explain)

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

Texel Rate

The Radeon HD 7950 3GB is quite a bit (approximately 474%) better 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 using high levels of AA is important to you, then the Radeon HD 7950 3GB is the winner, by a large margin. (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 data (in units of megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
