Radeon R7 370 4G vs Radeon R9 270

Intro

Compare those specifications to the Radeon R9 270, which has GPU clock speed of 900 MHz, and 2048 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is made up of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 4G		110 Watts
Radeon R9 270		150 Watts
	Difference: 40 Watts (36%)

Memory Bandwidth

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

Texel Rate

The Radeon R9 270 should be a small bit (about 15%) more effective at anisotropic filtering 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 running with high levels of AA is important to you, then the Radeon R7 370 4G is the winner, but not by far. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
