Radeon HD 7850 vs Radeon R9 M375

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 7850 should be a lot faster than the Radeon R9 M375 in general. (explain)

Radeon HD 7850		153600 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 118400 (336%)

Texel Rate

The Radeon HD 7850 will be much (more or less 36%) better at AF than the Radeon R9 M375. (explain)

Radeon HD 7850		55040 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 14440 (36%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 7850 is a better choice, and very much so. (explain)

Radeon HD 7850		27520 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 11280 (69%)

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 information (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core 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 most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
