Radeon HD 5450 vs Radeon R7 M360

Intro

Compare all of that to the Radeon R7 M360, which comes with core clock speeds of 1125 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M360, in theory, should perform quite a bit faster than the Radeon HD 5450 in general. (explain)

Radeon R7 M360		16000 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R7 M360 will be a lot (about 419%) better at AF than the Radeon HD 5450. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 21800 (419%)

Pixel Rate

The Radeon R7 M360 should be much (approximately 246%) more effective at full screen anti-aliasing than the Radeon HD 5450, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 6400 (246%)

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 data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 fill rate is also dependant on many 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.
