Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R5 M330 should in theory be a small bit better 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 is quite a bit (approximately 296%) more effective at anisotropic filtering than the Radeon HD 5450. (explain)

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

Pixel Rate

The Radeon R5 M330 should be quite a bit (approximately 217%) more effective at FSAA than the Radeon HD 5450, and capable of handling higher resolutions without slowing down too much. (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 information (counted in MB 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 the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
