Radeon HD 7950 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which features a core clock speed of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7950 should be quite a bit faster than the Radeon R9 M375 in general. (explain)

Radeon HD 7950		240000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 204800 (582%)

Texel Rate

The Radeon HD 7950 should be a lot (about 121%) better at anisotropic filtering than the Radeon R9 M375. (explain)

Radeon HD 7950		89600 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 49000 (121%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7950 is superior to the Radeon R9 M375, and very much so. (explain)

Radeon HD 7950		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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
