Radeon HD 5850 vs Radeon R7 370 4G

Intro

The Radeon HD 5850 features a GPU core clock speed of 725 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 1440(288x5) SPUs, 72 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon R7 370 4G, which has core clock speeds of 975 MHz on the GPU, and 1400 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

Radeon R7 370 4G 179200 MB/sec
Radeon HD 5850 128000 MB/sec
Difference: 51200 (40%)

Texel Rate

The Radeon R7 370 4G is a little bit (approximately 20%) more effective at texture filtering than the Radeon HD 5850. (explain)

Radeon R7 370 4G 62400 Mtexels/sec
Radeon HD 5850 52200 Mtexels/sec
Difference: 10200 (20%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 370 4G is superior to the Radeon HD 5850, and very much so. (explain)

Radeon R7 370 4G 31200 Mpixels/sec
Radeon HD 5850 23200 Mpixels/sec
Difference: 8000 (34%)

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 data (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
