Radeon R5 M330 vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which comes with GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 550 should perform much faster than the Radeon R5 M330 in general. (explain)

Radeon RX 550		114688 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 100288 (696%)

Texel Rate

The Radeon RX 550 should be much (approximately 71%) faster with regards to anisotropic filtering than the Radeon R5 M330. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 14600 (71%)

Pixel Rate

The Radeon RX 550 is quite a bit (more or less 114%) better at full screen anti-aliasing than the Radeon R5 M330, and also will be capable of handling higher screen resolutions better. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 9360 (114%)

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 megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
