Question: I've been looking at some very cheap tablet computers made in China and one goes by the English brand name "Cube" or "Alldocube" or "cube51". Their Chinese brand name is "酷比魔方" (Kù bǐ mófāng).

I see that "魔方" is the Chinese name of Rubik's Cube and that "酷" is a colloquial or slang term like "cool" (as well as other meanings).

Even though "酷比" gets lots of Google hits it could just be a regular phrase. I see that "比" has a meaning "than", among others.

So does the brand name "酷比魔方" just translate to the phrase "Cooler than Rubik's Cube", or is "酷比" actually some kind of compound as well.

Google Translate translates "酷比" as "cool", which is one clue that maybe it's not just a phrase?

Answer: 
I don't think 酷比 has any virtual meaning. But one can argue it means cool guy. 比 is a homophone of 逼, which is a homophone of 屄， which means female genital. It can be used to refer people. For example, 傻逼 means ass-hole. Similarly, 酷逼 means cool guy. Generally, 酷比 is just a name without any virtual meaning.
it might comes from 酷毙了(sounds similar) which means being awesome/cool. 酷比 doesn't have any meaning by itself.
