Radeon R7 370 4G vs Radeon R9 270

Intro

The Radeon R7 370 4G comes with a GPU clock speed of 975 MHz, and the 4096 MB of GDDR5 memory runs at 1400 MHz through a 256-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon R9 270, which features a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 RAM set to run at 1400 MHz through a 256-bit bus. It also features 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Radeon R7 370 4G 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 perform the same. (explain)

Texel Rate

The Radeon R9 270 should be just a bit (more or less 15%) more effective at AF than the Radeon R7 370 4G. (explain)

Radeon R9 270 72000 Mtexels/sec
Radeon R7 370 4G 62400 Mtexels/sec
Difference: 9600 (15%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 370 4G is the winner, though only just barely. (explain)

Radeon R7 370 4G 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 largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
