Radeon HD 5550 vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which comes with a clock frequency of 1030 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M330 will be 13% faster than the Radeon HD 5550 overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R5 M330 will be 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 lots of anti-aliasing is important to you, then the Radeon R5 M330 is superior to the Radeon HD 5550, by far. (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: 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. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
