Tirias Research founder and principal analyst Jim McGregor outlines how his firm connects semiconductor roadmaps, cloud infrastructure and emerging compute paradigms to guide technology vendors and enterprises through architectural transitions. He positions Tirias as a custom research and advisory shop that tracks everything from IP blocks and SoCs to full data center and edge deployments across AI, HPC and quantum-ready systems. https://tiriasresearch.com/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

He characterizes Supercomputing 2025 #SC25 as a turning point where classical high-performance computing, large-scale AI and early quantum computers are converging into a single conversation. Using IBM’s “quantum chandelier” as a visual anchor, McGregor explains how competing qubit technologies could eventually yield a single quantum processor capable of outperforming today’s Top500 supercomputers on targeted workloads. That leap unlocks scenarios like real-time global weather modeling, accelerated materials discovery and fast genomic analysis that are impractical even on the largest current clusters.
Quantum also reshapes security. McGregor emphasizes the “harvest now, decrypt later” threat model, where attackers capture encrypted traffic today and wait for future quantum systems to break current public-key schemes. He argues that organizations should already be migrating to NIST-approved post-quantum cryptography, designing protocols, key management and hardware roots of trust so that sensitive data remains protected even when practical quantum accelerators become widely available.
On the classical compute side, he discusses Nvidia’s Arm-based Grace server CPUs and upcoming Vera/Blackwell-era platforms as tightly coupled companions to GPU accelerators for AI-centric nodes, while also noting competing heterogeneous designs from AMD and others. He links these product trends to a wave of new exascale projects, including future US Department of Energy systems and additional AMD-powered exascale machines in Europe, as vendors push toward AI-optimized “AI factory” data centers rather than traditional monolithic supercomputers.
McGregor closes by walking through the rest of the SC25 show floor to illustrate how every subsystem is scaling together: Micron’s 245 TB SSDs for dense storage, high-bandwidth networking from companies like Broadcom and Cisco, and visually striking liquid-cooling deployments that make ultra-dense AI racks thermally feasible. Filmed at Supercomputing 2025 in St. Louis, the discussion frames the modern data center as a single engineered system where memory, interconnects, accelerators, cooling and power delivery all co-evolve to meet the demands of HPC, AI and, increasingly, quantum workloads.
