Radeon HD 5870 vs Radeon R7 370 2G

Intro

The Radeon HD 5870 features a GPU core clock speed of 850 MHz, and the 1024 MB of GDDR5 memory runs at 1200 MHz through a 256-bit bus. It also features 1600(320x5) SPUs, 80 TAUs, and 32 Raster Operation Units.

Compare those specs to the Radeon R7 370 2G, which has a core clock speed of 975 MHz and a GDDR5 memory speed of 1400 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Radeon HD 5870 153600 MB/sec
Difference: 25600 (17%)

Texel Rate

The Radeon HD 5870 is a small bit (more or less 9%) more effective at anisotropic 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 running with a high resolution is important to you, then the Radeon R7 370 2G is superior to the Radeon HD 5870, 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 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.
