Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 370 4G should in theory be much better than the Radeon HD 3470 256MB overall. (explain)

Radeon R7 370 4G		179200 MB/sec
Radeon HD 3470 256MB		30400 MB/sec
	Difference: 148800 (489%)

Texel Rate

The Radeon R7 370 4G should be much (about 1850%) faster with regards to texture filtering than the Radeon HD 3470 256MB. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 59200 (1850%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 370 4G is superior to the Radeon HD 3470 256MB, and very much so. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 28000 (875%)

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 information (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock 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 that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
