Current AI chips face a transmission bottleneck where they’re pushing 200Gbps per lane, so even the slightest interference can affect performance. Possibly realizing that there needs to be a better way to maintain optimal server throughput, NVIDIA is reportedly looking at an unlikely material to tackle one of AI hardware’s biggest headaches; PTFE, better known by the brand name Teflon and as the coating on non-stick pans.
PTFE wastes far less energy, making it suitable for achieving NVIDIA’s goals, but material complexity makes it difficult to employ
Teflon was showcased at this year’s TPCA Show after NVIDIA displayed its latest NVLink switch board at the OCP summit in early October and was said to be considering the PTFE. The reason for repurposing non-stick cookware material to be used in AI chips boils down to signal loss reduction. As stated above, AI chips are reaching their transmission limits, and because co-packaged optics isn’t ready yet, improving the circuit board is currently the most direct solution available.
PTFE wastes far less signal energy than the resins used in boards today, so it’s no surprise that industry sources say NVIDIA plans to use it in a Rubin…
