Radeon R7 370 2G vs Radeon R9 270

Intro

The Radeon R7 370 2G makes use of a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 RAM runs at a frequency of 1400 MHz on this model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Compare all that to the Radeon R9 270, which has a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1400 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 Texture Address Units, and 32 ROPs.

Radeon R7 370 2G 110 Watts
Radeon R9 270 150 Watts
Difference: 40 Watts (36%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon R9 270 is a little bit (about 15%) faster with regards to anisotropic filtering 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

If using high levels of AA is important to you, then the Radeon R7 370 2G is the winner, not by a very large margin though. (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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
