New bill sheds light on what kind of high-end chips are considered too sensitive; proposal lacks GOP support

House Democrats unveiled a new bill on Friday to set legal thresholds for chips deemed too advanced to send to China without congressional approval, attempting to set clear limits in the ongoing debate about how tightly to control the flow of the technology amid national security concerns.

Under the bill, a chip would be subject to review if it exceeds certain benchmarks, including a total processing performance 2,400 or performance density of 1.6, memory speeds of 4,100 gigabytes per second, or interconnect speeds of 1,100 GB/s. Chips that combine memory and interconnect speeds above 5,100 GB/s would also qualify.
