Radeon R7 M360 vs Radeon R9 270

Intro

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 uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 270 should theoretically be much better than the Radeon R7 M360 in general. (explain)

Radeon R9 270		179200 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 163200 (1020%)

Texel Rate

The Radeon R9 270 is a lot (approximately 167%) more effective at AF than the Radeon R7 M360. (explain)

Radeon R9 270		72000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 45000 (167%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 270 is the winner, by far. (explain)

Radeon R9 270		28800 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 19800 (220%)

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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the 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 the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
