From New AI Architecture Demonstration Achieves 50% Speedup Using Nvidia GPUs

How could the Attention-FFN Disaggregation demonstration affect Astera Labs?

Possible What happens if… A possibility worth considering, not a forecast.

New AI architecture may boost demand for Astera Labs' connectivity This disaggregated approach requires extremely fast, low-latency communication to manage the handoff of data between the two types of hardware. Astera Labs provides critical connectivity and switching solutions designed for high-performance computing platforms, making its technology essential for managing the 400 gigabits per second per cluster communication required by this new architecture.

The facts so far

As reported. Each one links to where it comes from.

  • The AFD configuration cut time-per-output-token from 2.59 milliseconds on a standalone H100 to 1.28 milliseconds, a 50.6 percent reduction.techtimes.com
  • Communication between the H100 servers and Corsair cards runs through d-Matrix's JetStream network interface cards at 400 gigabits per second per cluster.techtimes.com
  • The live demonstration used GPT-OSS-20B, a publicly released mixture-of-experts model with 20.9 billion total parameters.techtimes.com
  • The Corsair XPU uses on-chip SRAM delivering a claimed 150 TB/s, roughly 45 times that figure of NVIDIA's H100 HBM3 at 3.35 terabytes per second.techtimes.com

Why it matters

The validation of Attention-FFN Disaggregation signals a major shift toward disaggregated, mixture-of-experts (MoE) architectures in large language models. This architectural trend moves away from monolithic GPU designs, requiring operators to build complex clusters that integrate multiple specialized hardware components, such as GPUs and dedicated accelerators.

For Astera Labs, this shift is significant because the performance of these new, highly distributed systems is no longer solely dependent on the compute power of the individual chips. Instead, the ability to manage the massive, low-latency data movement between different specialized processors becomes the primary bottleneck, making high-speed connectivity solutions critical for commercial viability.

What we don't know yet

  • How quickly will operators adopt this proprietary hardware-software stack?
  • Will the industry shift toward dense transformer architectures, negating the benefit of AFD?

What would change this answer

D-Matrix expands the Squadron cluster to larger MoE models like GLM 5.x and Kimi K3This would increase the scale and complexity of the required interconnects, driving up demand for high-performance solutions like those offered by Astera Labs.
A major competitor validates the AFD architecture using open-source siliconThe market might become more commoditized, potentially reducing the reliance on proprietary stacks and specialized connectivity solutions.
