Radeon HD 5670 vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

The Radeon R9 M380 will be a lot (about 158%) better at AF than the Radeon HD 5670. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 24500 (158%)

Pixel Rate

The Radeon R9 M380 will be quite a bit (about 158%) faster with regards to AA than the Radeon HD 5670, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 9800 (158%)

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 transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
