USB Type-C and Thunderbolt Difference
USB-C and Thunderbolt are related but distinct
technologies. USB-C is a connector standard, while Thunderbolt is a
high-speed interface protocol that can utilize the USB-C connector. Thunderbolt
offers significantly faster data transfer speeds and greater bandwidth than
standard USB-C.
Here's a more detailed breakdown:
USB-C:
·
Connector
Standard:
USB-C is a physical
connector type, a reversible 24-pin connector, and is widely used for various
devices (phones, laptops, etc.).
·
Versatility:
USB-C supports multiple
protocols, including USB (various versions like 3.0, 3.1, etc.) and can also be
used with Thunderbolt.
·
Data
Transfer:
USB-C's data transfer
speeds vary depending on the USB version it supports (e.g., USB 3.1 Gen 2
offers up to 10 Gbps).
·
Power
Delivery:
USB-C supports power
delivery (USB PD), allowing for charging of devices with higher wattage (up to
100W with USB PD 3.0).
·
Cost:
Generally,
USB-C devices and cables are more affordable and readily available than
Thunderbolt-enabled devices.
Thunderbolt:
·
Interface
Protocol:
Thunderbolt is a
high-speed interface protocol developed by Intel (now also including USB4) that
leverages the USB-C connector.
·
High
Speed:
Thunderbolt 3 and 4 offer
speeds of up to 40 Gbps, significantly faster than standard USB-C.
·
Bandwidth:
Thunderbolt provides more
bandwidth than USB-C, enabling it to handle multiple high-bandwidth peripherals
simultaneously (e.g., dual 4K displays, external GPUs).
·
Dual
Functionality:
Thunderbolt ports can also
handle USB devices and protocols, making them backward compatible.
·
Cost:
Thunderbolt devices and
cables tend to be more expensive due to the technology's higher performance
capabilities.
·
Use
Cases:
Thunderbolt
is ideal for professional workflows requiring high-speed data transfer,
external storage, and high-resolution displays.
