Radeon HD 6670 (OEM) vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which uses a 28 nm design. AMD has clocked the core speed at 725 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

The Radeon HD 6670 (OEM) should be a small bit (more or less 10%) faster with regards to anisotropic filtering than the Radeon R7 M265. (explain)

Radeon HD 6670 (OEM)		19200 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 1800 (10%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 6670 (OEM) is the winner, but it probably won't make a huge difference. (explain)

Radeon HD 6670 (OEM)		6400 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 600 (10%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
