Intel announced that the Thunderbolt would be available to PC manufacturers in April 2012 with a priori chips cheaper and possibly integration in some chipsets accompanying Ivy Bridge, the next processor Intel.Actuellement, the only company to offer machines is compatible Apple, for nearly a year. But rumors indicate that Asus and Sony will offer the technology in their high-end machines, and Gigabyte will offer a motherboard compatible with the standard in April 2012. The current problem is essentially the price Thunderbolt: The controller is expensive ($ 20), the cables very expensive and only Apple products – € 50 – and the market too small to attack them as props in masse.L ‘ Another problem is the interest of technology: if the bandwidth of the Thunderbolt is high – about 1 GB / s in practice – the interest is not huge. USB 3.0, although cheaper, is powerful enough for most needs in the world of storage and is more universal. Similarly, if the Thunderbolt carries the image along with the data, the DisplayPort standard is used. And the latter, it is common on graphics cards, is not on the screens. A final point is disturbing: the fact that it is difficult to propose expansion cards Thunderbolt. As the standard features of PCI-Express and Video, its integration on an expansion card is not obvious: it would be optimal to install the chip on a graphics card with switches to separate PCI-Express dedicated to Thunderbolt connector and those dedicated to the GPU, which would greatly increase the cost of the graphics card. Rumors have also quite clear on this point: they speak of motherboards (ie with a PGI) or complete systems, not PCI-Express.
