Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R5 M230 should in theory perform a small bit faster than the Radeon R5 M330 overall. (explain)

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

Texel Rate

The Radeon R5 M330 is quite a bit (about 32%) more effective at AF than the Radeon R5 M230. (explain)

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

Pixel Rate

The Radeon R5 M330 is much (more or less 164%) faster with regards to FSAA than the Radeon R5 M230, and also able to handle higher resolutions while still performing well. (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 (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it 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, 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 texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
