Radeon HD 5550 vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M330 should be 13% quicker than the Radeon HD 5550 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon R5 M330 should be much (about 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 running with a high screen resolution 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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 get to the max fill rate.
