Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 4850 1GB, in theory, should perform much faster than the Radeon R7 M360 overall. (explain)

Radeon HD 4850 1GB		63552 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 47552 (297%)

Texel Rate

The Radeon R7 M360 should be a small bit (approximately 8%) more effective at anisotropic filtering than the Radeon HD 4850 1GB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4850 1GB		25000 Mtexels/sec
	Difference: 2000 (8%)

Pixel Rate

The Radeon HD 4850 1GB should be a bit (more or less 11%) faster with regards to FSAA than the Radeon R7 M360, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 4850 1GB		10000 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 1000 (11%)

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 max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
