Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M360 is 25% quicker than the Radeon HD 4550 256MB in general, because of its higher bandwidth. (explain)

Radeon R7 M360		16000 MB/sec
Radeon HD 4550 256MB		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R7 M360 should be much (approximately 463%) faster with regards to anisotropic filtering than the Radeon HD 4550 256MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4550 256MB		4800 Mtexels/sec
	Difference: 22200 (463%)

Pixel Rate

The Radeon R7 M360 should be quite a bit (more or less 275%) more effective at FSAA than the Radeon HD 4550 256MB, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 4550 256MB		2400 Mpixels/sec
	Difference: 6600 (275%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
