Radeon HD 3470 256MB vs Radeon R9 M375X

Intro

The Radeon HD 3470 256MB makes use of a 55 nm design. AMD has clocked the core speed at 800 MHz. The DDR2 RAM is set to run at a frequency of 950 MHz on this card. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 Rasterization Operator Units.

Compare those specs to the Radeon R9 M375X, which has a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

The Radeon R9 M375X is a lot (more or less 1169%) better at anisotropic filtering than the Radeon HD 3470 256MB. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 37400 (1169%)

Pixel Rate

The Radeon R9 M375X should be quite a bit (about 408%) more effective at AA than the Radeon HD 3470 256MB, and also capable of handling higher resolutions more effectively. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon HD 3470 256MB 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
