Radeon HD 5570 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 RAM is set to run at a frequency of 1100 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Radeon HD 5570		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 should be much (approximately 212%) better at AF than the Radeon HD 5570. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 27600 (212%)

Pixel Rate

The Radeon R9 M375 is much (approximately 212%) faster with regards to AA than the Radeon HD 5570, and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 11040 (212%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
