Here is the Technical Intelligence Report for 2026-03-02.

Executive Summary

  • AMD Server Hardware: New benchmarks compare EPYC 9755 (Zen 5) against EPYC 9745 (Zen 5C), highlighting the 9745 as a high-density solution for 400W power-constrained environments, despite halving the L3 cache.
  • Software Optimization: Early testing of Linux Kernel 7.0 on AMD Zen 5 hardware reveals significant “free” performance gains in database workloads (PostgreSQL, MariaDB, Redis) compared to Linux 6.19.
  • Firmware Ecosystem: Momentum for AMD openSIL (Open Silicon Initialization Library) grows, with 9elements porting Coreboot + openSIL to consumer Ryzen 7000 Framework laptops, paving the way for Zen 6 production readiness.
  • Competitor Analysis (NVIDIA):
    • Strategic: NVIDIA is investing heavily ($4B+) in Lumentum and Coherent to secure optical interconnects and Optical Circuit Switches (OCS) for future “Rubin Ultra” AI clusters, signaling a shift away from electrical switching for spine networks.
    • Tactical: A critical driver bug (v595.59) disabled fans on RTX GPUs, forcing an emergency rollback/update; Steam Survey data shows an anomalous spike in RTX 5070 usage, likely attributed to Chinese internet cafes rather than organic sell-through.

[2026-03-02] Framework 16 Gen1 Seeing Coreboot + AMD openSIL Port, Framework 13 AMD Gen1 To Follow

Source: Phoronix

Key takeaway relevant to AMD:

  • Demonstrates the maturation of AMD openSIL (Open Silicon Initialization Library), which is critical for AMD’s plan to replace AGESA in future Zen 6 platforms.
  • Expanding open-source firmware support to consumer laptops (Framework) increases AMD’s appeal to security-conscious and developer communities.

Summary:

  • Firmware consultancy 9elements is porting Coreboot and AMD openSIL to the Framework 16 Gen1 (Ryzen 7000 “Phoenix”).
  • This effort complements work by 3mdeb on EPYC 9005 and MSI AM5 motherboards.

Details:

  • Target Hardware: Framework 16 (Ryzen 7000 series) initially, followed by Framework 13.
  • Technical Status: Work-in-progress; currently tackling memory training and early silicon initialization.
  • Codebase: Involves integrating AMD openSIL “Phoenix” code into the Coreboot environment.
  • Strategic Context: AMD is actively working to bring openSIL to production status for next-generation Zen 6 platforms. Current work on Ryzen 7000 acts as a proof-of-concept and development testbed.

[2026-03-02] AMD EPYC Turin 128 Core Comparison: EPYC 9745 “Zen 5C” vs. EPYC 9755 “Zen 5”

Source: Phoronix

Key takeaway relevant to AMD:

  • The EPYC 9745 serves a critical market segment: customers needing high core counts (128) but restricted by power delivery (400W limits) or thermal density, where the flagship 9755 (500W) cannot fit.
  • It positions AMD competitively against AmpereOne A128 processors in the high-efficiency cloud native market.

Summary:

  • A comparative review of the EPYC 9755 (128 “full fat” Zen 5 cores) vs. the EPYC 9745 (128 dense Zen 5C cores).
  • Both are priced similarly (~$7200 USD), making the choice dependent on power constraints and cache requirements.

Details:

  • EPYC 9755 Specs: 128 Zen 5 cores, 500W TDP, 2.1GHz Base / 4.1GHz Boost, 512MB L3 Cache.
  • EPYC 9745 Specs: 128 Zen 5C cores, 400W TDP (configurable down to 320W), 2.4GHz Base / 3.7GHz Boost, 256MB L3 Cache.
  • Architectural Differences: The 9745 utilizes “Zen 5C” cores which are physically denser and feature half the L3 cache of the standard Zen 5. However, ISA support (AVX-512) is identical.
  • Power Config: The 9745 at 320W cTDP is positioned to compete with the AmpereOne A128 (275W usage).
  • Platform: Tested on Gigabyte MZ33-AR1 (Single Socket) with liquid cooling.
  • Use Case: The 9745 is optimized for motherboards strictly limited to 400W TDP or high-density deployments where thermal output is the primary bottleneck.

(NVIDIA, Trends, Industry)

[2026-03-02] Nvidia Sees The Light On Silicon Photonics And Maybe Optical Switching

Source: The Next Platform

Key takeaway relevant to AMD:

  • NVIDIA is aggressively vertically integrating optical networking, which presents a threat to AMD’s Infinity Fabric scaling if AMD relies solely on third-party standard implementations.
  • The move toward Optical Circuit Switching (OCS) suggests future AI clusters will move away from electrical switching for spine/scale-up networks to reduce power by up to 65%.

Summary:

  • NVIDIA has committed ~$2 billion each to Lumentum and Coherent for R&D and capacity access.
  • The focus is on Co-Packaged Optics (CPO) for switches and potentially GPUs, as well as Optical Circuit Switches (OCS).

Details:

  • Investments: Non-exclusive “multibillion dollar purchase commitments” to Lumentum and Coherent. Not full acquisitions (avoids antitrust).
  • Technology 1: Co-Packaged Optics (CPO): Already used in Quantum-X (InfiniBand) and Spectrum-X (Ethernet). Future need seen for CPO on GPU compute engines and NVSwitches to solve “beachfront” I/O limitations.
  • Technology 2: Optical Circuit Switching (OCS):
    • Lumentum: MEMS-based R300 switch (similar to Google’s “Apollo” OCS). High latency (ms) but zero power for maintaining links.
    • Coherent: Liquid Crystal based “Datacenter Lightwave Cross Connect” (DLX).
  • Implications:
    • Replacing electrical switches with OCS in the spine could cut network power by 65%.
    • Latency in OCS is 5-10x lower than electrical Ethernet switching.
    • Speculation that NVIDIA’s “Rubin Ultra” generation (“Kyber” rack) may switch to Torus or Dragonfly topology using OCS spines.

[2026-03-02] Nvidia releases new GeForce 595.71 driver to fix serious fan control bug

Source: Tom’s Hardware

Key takeaway relevant to AMD:

  • Provides a temporary competitive talking point regarding driver stability and QA, as the NVIDIA bug was hardware-threatening (stopped cooling fans).

Summary:

  • NVIDIA released driver v595.71 to replace the recalled v595.59.
  • The previous version caused fans on RTX 30, 40, and 50-series cards to stop spinning, risking hardware overheating.

Details:

  • Bug Severity: High. Fans were not detected or stopped spinning under load.
  • Affected Hardware: RTX 30, 40, and 50 series.
  • New Features: The fix driver also adds optimizations for Resident Evil Requiem and Marathon (DLSS/Reflex support).
  • Context: This follows other recent NVIDIA driver issues, including a March 2025 stability issue with older cards following the RTX 50 launch.

[2026-03-02] Nvidia’s RTX 5070 seemingly crushes memory shortages to reign supreme as Steam’s number one GPU

Source: Tom’s Hardware

Key takeaway relevant to AMD:

  • Market share data for the RTX 5070 is likely inflated and inaccurate, masking true sell-through rates.
  • The reported decline in Windows 11 usage is an anomaly that contradicts broader OS adoption trends.

Summary:

  • Steam Hardware Survey (Feb 2026) shows RTX 5070 market share jumping 6.55% in one month to 9.42% total share.
  • Tom’s Hardware attributes this to Chinese Internet Cafes (PC Bangs) skewing data during the Chinese New Year holiday.

Details:

  • Statistical Anomaly: A single-month jump of 6.55% for a $550+ GPU is historically unprecedented.
  • Chinese Impact: Users from China increased by 30.74% (totaling 54.6% of survey). Internet cafes use diskless boot/cloned images, potentially causing duplicate counting of high-end hardware (RTX 5070).
  • System Specs Trends:
    • Systems with 32GB RAM increased by 18.91% (despite global memory shortages).
    • Windows 11 usage declined by 10.43%, while Windows 10 grew 12.46%, further suggesting the data is skewed by legacy internet cafe images rather than consumer behavior.
