Radeon R7 370 2G vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which features core speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon R9 M375		35200 MB/sec
	Difference: 144000 (409%)

Texel Rate

The Radeon R7 370 2G is quite a bit (more or less 54%) more effective at texture filtering than the Radeon R9 M375. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 21800 (54%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 370 2G is the winner, by a large margin. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 14960 (92%)

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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, 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 most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
