AMD HD 4860 and HD 4750 are China only
 

There has been some talk around the net about the Radeon HD 4860 and the Radeon HD 4750 cards that tipped up on INPAI, a Chinese web site, and some info hinted that these might as well show up in Europe. We did a bit of checking, and we can now confirm that AMD doesn't plan to launch these cards outside of China, at least not in near future.

The Chinese market is usually quite different than Europe or the States, and it's no wonder that these new cards are exclusive for Chinese market. The HD 4860, which should start to ship on August 18th, and this addition to the sub US $150 graphics card market might have a bright future in China.
