Comcast tests the first multigigabit cable modem
Comcast is now considerably closer to making multigigabit cable internet a reality. The company has successfully tested the first 10G modem capable of multigigabit speeds. The Broadcom-built prototype used the full duplex DOCSIS 4.0 standard to provide download and upload bandwidth topping 4Gbps. For context, maintaining that performance would let you download all of Call of Duty: Vanguard's recommended install size for PC (61GB) in just over two minutes.
While this was a lab test, it's still a significant step forward. The company previously reached those speeds using a virtualized system, and in October 2020 was 'only' managing 1.25Gbps with the new DOCSIS technology. The new format is notable for not only improving downstream speeds, but enabling symmetric uploads and reducing lag.
