Cornell Study Shows GSIT’s Compute-In-Memory APU Matches GPU Performance with 98% Lower Energy Use
Independent Cornell Research Confirms APU Achieves GPU-Class AI Performance with Massive Energy Savings
A landmark study from Cornell University has given a major vote of confidence to GSI Technology’s (NASDAQ: GSIT) Compute-In-Memory (CIM) Associative Processing Unit (APU). The Gemini-I APU, as detailed in the paper published by Cornell and showcased at the ACM Micro ’25 conference, delivers performance on par with high-end GPUs, such as NVIDIA’s A6000, while consuming just a fraction of the energy. Specifically, the study revealed a remarkable 98% reduction in energy use for AI workloads—underscoring GSI’s potential as a disruptive force in the energy-conscious world of artificial intelligence.
Performance Data Highlights: APU Versus Industry Standards
Cornell’s research didn’t just stop at energy savings. Benchmarking against both leading GPUs and traditional CPUs, the Gemini-I APU consistently matched or surpassed GPU throughput for Retrieval-Augmented Generation (RAG) tasks—across data sets from 10GB up to 200GB. Even more impressive, the APU processed certain retrieval tasks up to 80% faster than standard CPUs.
| Technology | Throughput (RAG Tasks) | Energy Consumption | Processing Time (vs. CPU) |
|---|---|---|---|
| GSI Gemini-I APU | Comparable to NVIDIA A6000 GPU | Over 98% less than GPU | Up to 80% faster |
| NVIDIA A6000 GPU | High (GPU-class) | High | Baseline |
| Standard CPU | Lower | Lower | Slower |
Industry Impact: From Edge Robotics to Aerospace
This validation by an independent research team goes beyond academic acclaim—it sets the stage for real-world applications in power-constrained settings like edge AI, robotics, drones, IoT, defense, and aerospace. The APU’s memory-centric design excels where energy and cooling are at a premium, delivering strong AI inference capabilities for customers that prioritize performance-per-watt.
Looking Ahead: GSIT's Next-Generation Silicon Could Accelerate Adoption
GSI’s roadmap, as outlined by CEO Lee-Lean Shu, aims even higher. The recently introduced Gemini-II silicon reportedly delivers up to 10x faster throughput with even lower latency and improved efficiency. Meanwhile, the next-in-line “Plato” architecture promises further compute power gains at lower power, specifically targeting embedded edge applications.
The implications are broad: AI systems that were previously limited by power, heat, or cooling constraints may soon have a practical solution, making this breakthrough relevant for everything from autonomous drones to high-security data centers.

Takeaway: Disruption Potential for Energy-Efficient AI Markets
As performance-per-watt becomes a driving metric for enterprise and industrial AI solutions, GSI’s APU technology may have arrived at just the right moment. If subsequent silicon generations fulfill their promise, this approach could redefine how high-performance AI is deployed across the globe.
Investors and industry watchers may want to review the full Cornell paper and follow upcoming releases, as the push for energy-efficient AI platforms is just beginning to heat up.
