Radeon HD 4550 512MB vs Radeon R7 M360

Intro

Compare all that to the Radeon R7 M360, which makes use of a 28 nm design. AMD has clocked the core frequency at 1125 MHz. The DDR3 memory runs at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M360 should perform a lot faster than the Radeon HD 4550 512MB in general. (explain)

Radeon R7 M360		16000 MB/sec
Radeon HD 4550 512MB		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 512MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 22200 (463%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M360 is a better choice, by far. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 4550 512MB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
