USB3.0 and Thunderbolt: Another standard war is forming

Xavier Lauwaert, HP's consumer desktop product manager, said when he talked about HP's new desktop lacking the Thunderbolt port: "At present, everyone is very satisfied with the adoption of USB 3.0 on PCs. We need to adopt newer solutions that have not yet been obtained. verification."

Thunderbolt is a new peripheral input standard Intel has been developing this standard since 2009, this year will appear Apple's latest MacBook Pro notebook and iMac integrated desktop.

Thunderbolt advertises its two-way data transmission rate of up to 10Gbps, which means that each port can input and output 10Gb data simultaneously.

Thunderbolt also supports DisplayPort and PCI Express 2.0 standards. This means Thunderbolt can also act as a monitor port while transferring data quickly. Thunderbolt also supports internal graphics cards and external video processing devices when bandwidth is close.

Since February 24th this year, the Thunderbolt port has appeared on the new MacBook Pro laptop. There is currently no Thunderbolt port on the Windows chip. Intel’s Dave Salvator said that Thunderbolt is expected to become popular in 2012.

There is currently no Thunderbolt peripheral on the market, but Apple representatives said earlier this month that Thunderbolt peripherals will be available this summer. A large number of manufacturers demonstrated Thunderbolt devices at the NAB show held in April this year, including external SSD products and video port centers.

USB 3.0 is sometimes referred to as SuperSpeed ​​USB

Since 2010, USB 3.0 has appeared in Windows laptops and desktops, and is the basic function of Windows PCs equipped with Intel's second-generation Core processors. Although the Intel motherboard chipset does not support USB 3.0, a large number of vendors sell USB 3.0 controller chips. USB 3.0 has a maximum data transfer rate of 5Gbps, but is backward compatible with a large number of existing USB 2.0 devices. Unlike Thunderbolt, USB 3.0 does not support any video bus or display standard.

From a technical point of view, Thunderbolt has advantages over USB 3.0, fast data transfer, and higher video and graphics device compatibility. However, USB 3.0 has been widely used. USB 3.0 hard disks and other devices have been sold together with USB 2.0 devices. Only one external monitor with Mini-DisplayPort cable is connected to the Thunderbolt port.

How will Thunderbolt and USB 3.0 be confronted? First of all, the two standards are not necessarily antagonistic. Intel has said that the next-generation Ivy Bridge CPU architecture chipset launched at the end of this year will support both standards. PC vendors can easily adopt two standards in the same system, similar to existing USB 2.0, FireWire 400, and eSATA ports on existing motherboards.

Second, although Apple and Intel jointly launched Thunderbolt on the market earlier this year, Windows vendors or motherboard makers do not have Thunderbolt options. Intel does not want to comment on this.

As for Laughter's comment, although HP is less risky when adopting the Thunderbolt and USB 3.0 standards a year later, HP still has a PC that it wants to sell. The HP TouchSmart integrated touch screen, Blu-ray drive, and HDMI input/output are aimed at customers who have not yet realized the benefits of the Thunderbolt standard because Thunderbolt does not yet have compatible devices. USB 3.0 is the first choice for HP's desktop market because it supports a large number of existing devices. This is one of the reasons for the emergence of USB 3.0 ports on the HP TouchSmart 610.

The new iMac and MacBook Pro lack some consumer-oriented features compared to the Windows PCs in the same price category. The new iMac and MacBook Pro have achieved brilliant results. Adding Thunderbolt shows the forward-looking nature of Apple's decision-making, attracting digital media professionals and other customers. Video editing, which often moves large files between different workstations, prefers higher data transfer rates. Thunderbolt will help Apple attract such users.

Apple has made its USB 3.0 release to Thunderbolt clear. HP and other PC vendors will wait until a large number of customers benefit from receiving Thunderbolt. Once Intel's chipset to be released next year supports both Thunderbolt and USB 3.0 standards, it is expected that more PCs will also support both standards.
