Radeon HD 5550 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 memory runs at a frequency of 900 MHz on this specific card. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M330 will be 13% quicker than the Radeon HD 5550 in general, because of its greater bandwidth. (explain)

Radeon R5 M330		14400 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 is a lot (more or less 134%) more effective at AF than the Radeon HD 5550. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 11800 (134%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R5 M330 is superior to the Radeon HD 5550, and very much so. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 3840 (87%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
