Radeon HD 5850 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 RAM runs at a speed of 1100 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5850 is 264% quicker than the Radeon R9 M375 overall, because of its higher bandwidth. (explain)

Radeon HD 5850		128000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 92800 (264%)

Texel Rate

The Radeon HD 5850 is much (approximately 29%) faster with regards to anisotropic filtering than the Radeon R9 M375. (explain)

Radeon HD 5850		52200 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 11600 (29%)

Pixel Rate

The Radeon HD 5850 should be a lot (more or less 43%) better at AA than the Radeon R9 M375, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 5850		23200 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 6960 (43%)

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 data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, 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 worked out by multiplying the total number of texture units 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
