Texas Instruments is to validate two new USB 3.0 controllers, which could therefore come - finally - to compete with the controllers from Renesas (NEC). Good news, one of two chips (the TUSB7340) supports four USB 3.0 ports, while the majority of current solutions are limited to only two ports. In practice, the motherboards that support more than two or more controllers connectors use either a USB 3.0 hub internal - Via offers a chip of this type -.
The chip still has some flaws. Its price, slightly higher than the two-door version, is one, although the difference is very small: $ 4.5 for a 4-port version and $ 3.5 for a 2 port model. The other fault is recurrent in this kind of chip: the chip interfaces to PCI-Express 1x (version 2.0), which limits the bandwidth to 500 Mb / s.
For four ports that can theoretically reach 5 gigabits / s (500MB / s for real) everyone is a bit lighter. This is not a big problem now, since few people have several external drives that can saturate the USB 3.0, but the democratization of SSDs in the future may show the limits of the chip quickly.
In fact, both chips will at least help democratize a little more USB 3.0, competition in this area arrive at last.
