Radeon HD 5750 512MB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Radeon R9 M375		35200 MB/sec
	Difference: 38400 (109%)

Texel Rate

The Radeon R9 M375 should be quite a bit (more or less 61%) faster with regards to texture filtering than the Radeon HD 5750 512MB. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 15400 (61%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M375 is a better choice, by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 5040 (45%)

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 data (measured in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 per 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 amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 get to the max fill rate.
