Radeon HD 6850 vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which comes with a core clock speed of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 6850, in theory, should perform a lot faster than the Radeon R9 M375 overall. (explain)

Radeon HD 6850		128000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 92800 (264%)

Texel Rate

The Radeon R9 M375 will be a little bit (approximately 9%) more effective at anisotropic filtering than the Radeon HD 6850. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 6850		37200 Mtexels/sec
	Difference: 3400 (9%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6850 is a better choice, and very much so. (explain)

Radeon HD 6850		24800 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 8560 (53%)

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 (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
