Radeon R5 M330 vs Radeon RX 480 4GB

Intro

Compare all of that to the Radeon RX 480 4GB, which has GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 480 4GB should theoretically perform quite a bit faster than the Radeon R5 M330 overall. (explain)

Radeon RX 480 4GB		229376 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 214976 (1493%)

Texel Rate

The Radeon RX 480 4GB should be a lot (more or less 683%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 140680 (683%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 480 4GB is the winner, and very much so. (explain)

Radeon RX 480 4GB		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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
