Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 should perform a small bit faster than the Radeon R5 M330 in general. (explain)

Radeon R5 M230		16000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R5 M330 should be a lot (about 32%) better at anisotropic filtering than the Radeon R5 M230. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 5000 (32%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M330 is a better choice, by a large margin. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 5120 (164%)

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 (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
