Radeon R7 370 2G vs Radeon R9 270

Intro

The Radeon R7 370 2G comes with a GPU clock speed of 975 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1400 MHz through a 256-bit bus. It also is made up of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon R9 270, which features clock speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Difference: 40 Watts (36%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon R9 270 is a small bit (approximately 15%) faster with regards to AF than the Radeon R7 370 2G. (explain)

Radeon R9 270 72000 Mtexels/sec
Radeon R7 370 2G 62400 Mtexels/sec
Difference: 9600 (15%)

Pixel Rate

The Radeon R7 370 2G should be a bit (about 8%) better at FSAA than the Radeon R9 270, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 370 2G 31200 Mpixels/sec
Radeon R9 270 28800 Mpixels/sec
Difference: 2400 (8%)

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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
