Radeon HD 5750 1GB vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 RAM runs at a speed of 1100 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 1GB should in theory be a lot better than the Radeon R9 M375 overall. (explain)

Radeon HD 5750 1GB		73600 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 38400 (109%)

Texel Rate

The Radeon R9 M375 is a lot (more or less 61%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 15400 (61%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375 is the winner, and very much so. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 5750 1GB		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 (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
