Radeon HD 3470 512MB vs Radeon R9 M375

Intro

The Radeon HD 3470 512MB comes with a GPU core speed of 800 MHz, and the 512 MB of GDDR3 memory is set to run at 950 MHz through a 128-bit bus. It also is comprised of 40(8x5) Stream Processors, 4 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory is set to run at a frequency of 1100 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375, in theory, should be a small bit faster than the Radeon HD 3470 512MB overall. (explain)

Radeon R9 M375 35200 MB/sec
Radeon HD 3470 512MB 30400 MB/sec
Difference: 4800 (16%)

Texel Rate

The Radeon R9 M375 should be a lot (more or less 1169%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)

Radeon R9 M375 40600 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 37400 (1169%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375 is the winner, by far. (explain)

Radeon R9 M375 16240 Mpixels/sec
Radeon HD 3470 512MB 3200 Mpixels/sec
Difference: 13040 (408%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the 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 most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
