Radeon HD 6950 vs Radeon R9 M375

Intro

Compare those specs 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 frequency of 1100 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 6950 should perform quite a bit faster than the Radeon R9 M375 overall. (explain)

Radeon HD 6950		160000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 124800 (355%)

Texel Rate

The Radeon HD 6950 should be much (about 73%) faster with regards to AF than the Radeon R9 M375. (explain)

Radeon HD 6950		70400 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 29800 (73%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 6950 is the winner, and very much so. (explain)

Radeon HD 6950		25600 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 9360 (58%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
