Radeon HD 5870 vs Radeon R7 370 2G

Intro

The Radeon HD 5870 makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this specific model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 ROPs.

Compare all of that to the Radeon R7 370 2G, which uses a 28 nm design. AMD has set the core speed at 975 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this particular card. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 2G 110 Watts
Radeon HD 5870 188 Watts
Difference: 78 Watts (71%)

Memory Bandwidth

Theoretically, the Radeon R7 370 2G should be just a bit faster than the Radeon HD 5870 in general. (explain)

Radeon R7 370 2G 179200 MB/sec
Radeon HD 5870 153600 MB/sec
Difference: 25600 (17%)

Texel Rate

The Radeon HD 5870 should be a bit (more or less 9%) more effective at texture filtering than the Radeon R7 370 2G. (explain)

Radeon HD 5870 68000 Mtexels/sec
Radeon R7 370 2G 62400 Mtexels/sec
Difference: 5600 (9%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 370 2G is a better choice, but not by far. (explain)

Radeon R7 370 2G 31200 Mpixels/sec
Radeon HD 5870 27200 Mpixels/sec
Difference: 4000 (15%)

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 largest amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
