Radeon R5 M330 vs Radeon RX 480

Intro

Compare that to the Radeon RX 480, which has a core clock frequency of 1120 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It is made up of 2304 SPUs, 144 TAUs, and 32 ROPs.

Radeon R5 M330		14400 MB/sec
	Difference: 247744 (1720%)

Texel Rate

The Radeon RX 480 will be a lot (approximately 683%) better at texture filtering than the Radeon R5 M330. (explain)

Radeon RX 480		161280 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 140680 (683%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 480 is the winner, and very much so. (explain)

Radeon RX 480		35840 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 27600 (335%)

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 (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
