Radeon R7 M360 vs Radeon R9 270

Intro

Compare all of that to the Radeon R9 270, which features a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 memory set to run at 1400 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 270 should perform much faster than the Radeon R7 M360 overall. (explain)

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

Texel Rate

The Radeon R9 270 will be a lot (more or less 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 using a high resolution is important to you, then the Radeon R9 270 is a better choice, 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 largest amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
