Radeon HD 5450 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core speed at 1030 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R5 M330 should be a bit faster than the Radeon HD 5450 in general. (explain)

Radeon R5 M330		14400 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be quite a bit (more or less 296%) faster with regards to texture filtering than the Radeon HD 5450. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 15400 (296%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R5 M330 is a better choice, by far. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 5640 (217%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
