Radeon HD 3850 X2 vs Radeon R7 370 2G

Intro

Compare all of that to the Radeon R7 370 2G, which comes with core clock speeds of 975 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 3850 X2		105984 MB/sec
	Difference: 73216 (69%)

Texel Rate

The Radeon R7 370 2G should be quite a bit (more or less 192%) faster with regards to anisotropic filtering than the Radeon HD 3850 X2. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon HD 3850 X2		21376 Mtexels/sec
	Difference: 41024 (192%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 370 2G is the winner, by a large margin. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon HD 3850 X2		21376 Mpixels/sec
	Difference: 9824 (46%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
