Radeon HD 5870 vs Radeon R7 M360

Intro

Compare those specs to the Radeon R7 M360, which makes use of a 28 nm design. AMD has set the core frequency at 1125 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this model. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 5870 should be quite a bit faster than the Radeon R7 M360 in general. (explain)

Radeon HD 5870		153600 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 137600 (860%)

Texel Rate

The Radeon HD 5870 is much (more or less 152%) more effective at anisotropic filtering than the Radeon R7 M360. (explain)

Radeon HD 5870		68000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 41000 (152%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5870 is the winner, and very much so. (explain)

Radeon HD 5870		27200 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 18200 (202%)

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 (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
