IBM's Hermes: Digital Meets Analog for Energy-Efficient AI
IBM’s Hermes chip represents a bold step forward in AI hardware by combining digital circuits with phase-change memory (PCM). This hybrid approach enables Hermes to perform deep learning inference with remarkable efficiency. IBM claims that their analog AI chips are up to 14 times more energy-efficient than traditional all-digital devices.
According to a research paper published in Nature Electronics, matrix-vector multiplication (one of the main workloads for AI inferencing) could be performed directly on chip-stored weights. By performing these operations directly on chip-stored weights, it can significantly reduce the need for data movement between memory and processing units, which is often a bottleneck in traditional computing architectures. This approach can lead to faster processing times and lower energy consumption, making it particularly beneficial for AI inferencing tasks.

| Sohu is an AI Transformer On-A-Chip |
Etched’s Sohu: Transforming AI with Application-Specific Chips
Etched’s Sohu chip is a game-changer for large language models (LLMs). Designed as an application-specific integrated circuit (ASIC), the Sohu chip far-outperforms even Nvidia's cutting-edge H100 GPUs in AI inference. A single 8xSohu server delivers performance equivalent to 160 H100 GPUs(!)
Etched describes the Sohu as an “AI transformer on a chip,” meaning it’s application design is specifically for a specific transformer-based architecture. This architecture would change depending on the AI model. Etched specifically mentions the Llama 70 Billion Parameter LLM model. The architecture-on-a-chip focus allows it to handle LLM inference with unparalleled speed and efficiency.

| Lightmatter's Light Chips are built different |
Lightmatter's Photo Processors: AI at the Speed of Light
Lightmatter, a spinout from MIT, is revolutionizing AI hardware with its Photon Processors. These chips use light, rather than electricity, for communication between processors on servers. By leveraging analog calculations and optical data transfer, Lightmatter’s processors run 1.5 to 10 times faster than Nvidia’s A100 GPUs.
“The two problems we are solving are ‘How do chips talk?’ and ‘How do you do these [AI] calculations?’, “With our first two products, Envise and Passage, we’re addressing both of those questions.” - Lightmatter CEO Nicholas Harris PhD
In addition to their speed, Lightmatter’s Photon Processors integrate seamlessly with popular AI frameworks like PyTorch and TensorFlow, making them accessible to developers. The use of photonic technology reduces latency and power consumption, offering a glimpse into a future where light-based computing becomes mainstream in AI.

| Apple M4 Chip with 2 Memory Modules |
Apple’s M4 Processor: Unified Memory for AI Power
Apple continues to innovate in AI hardware with its new M4 Processor. This chip combines a CPU, GPU, and Neural Processing Unit (NPU) into a unified architecture with shared memory. The Unified Memory design enables the M4 to offer significantly higher memory capacity (128GB Combined) compared to current GPUs like Nvidia’s 4090 and the upcoming 5090 (set to release in early 2025 with 32GB of VRAM).
Apple’s approach prioritizes efficiency and integration, making the M4 a powerful tool for both AI and general-purpose computing. The ability to share memory across components reduces bottlenecks and makes the M4 particularly suited for tasks like AI training and inference on consumer devices.
Make no mistake, Intel, AMD, Qualcomm, and Nvidia are also integrating AI into their PC chips.
