  • New IPs Included: Adds initial support for VCN 5.0.2 (Video Core Next) and JPEG 5.0.2 IP blocks.
  • Scheduler & Security: Implements updates for the MES 12.1 scheduler, DML (Display Mode Logger), and the PSP 13.0.15 (Platform Security Processor).
  • Fixes: Resolves ongoing issues with DisplayID handling, TLB fences, UserQ (user-queues), and includes legacy fixes dating back to Hainan GCN 1.0 GPUs.

🤼‍♂️ Market & Competitors

[2026-03-19] Walmart flooded with RTX 40-series GPUs as 50-series remains out of reach for most gamers

Source: Tom’s Hardware (GPUs)

Key takeaway relevant to AMD:

  • Nvidia’s ongoing Blackwell (RTX 50-series) shortages and pricing friction are forcing retailers to push last-gen inventory. This gives AMD’s RX 7000 series (specifically the 7900 XTX mentioned as a superior raster alternative to the 4080) extended market viability if AMD capitalizes on the pricing gap.

Summary:

  • Major retailers like Walmart are steeply discounting previous-generation Nvidia Ada Lovelace (RTX 40-series) graphics cards due to high pricing and lack of stock for the new RTX 50-series.
  • Price cuts are reaching nearly $500 on higher-end SKUs to stimulate stalling DIY PC hardware sales.

Details:

  • Pricing Shifts: The PNY RTX 4080 Super dropped from $1,501 to $1,019 (-$482). The RTX 4070 Ti Super fell to $799 (-$450).
  • Competitor Benchmark: The cheapest RTX 5070 currently retails at $629 (9% more expensive than the discounted 4070 Super) and suffers from an AI-driven memory shortage restricting stock.
  • Technical Implications: While RTX 40-series cards are discounted, buyers lose out on full Blackwell hardware features like 6X Multi-Frame Generation (restricted to 2X on Ada Lovelace).

[2026-03-19] Driving Down The AI System Roadmap With Nvidia

Source: The Next Platform

Key takeaway relevant to AMD:

  • Nvidia’s 2026-2028 roadmap reveals rapid interconnect and memory bandwidth scaling that AMD’s Instinct roadmap (MI400/MI500) will need to directly counter, particularly Nvidia’s move toward Co-Packaged Optics (CPO) to scale GPU domain sizes.

Summary:

  • A comprehensive look at Nvidia’s data center system roadmap spanning 2026 to 2028, outlining the transition from Blackwell to Rubin, and eventually to Feynman architectures.
  • Nvidia is heavily focusing on massive system-level scalability, interconnect evolution (NVLink 6/8), and integration with Groq inference engines.

Details:

  • 2026 (Vera-Rubin): 2H 2026 launch. Vera CPU features 88 custom Olympus cores with 1.8 TB/s NVLink C2C. Rubin R200 GPU uses 2 chips in a single socket with 288 GB HBM4, pushing 50 PFLOPS FP4.
  • 2027 (Rubin Ultra): Upgraded R300 doubles chip count to 4 per socket, hitting 100 PFLOPS FP4 and 1 TB of HBM4E memory (32 TB/sec bandwidth). Includes Kyber racks with 144 GPU sockets and NVLink 6 (3,600 GB/s bandwidth).
  • 2028 (Rosa-Feynman): Introduces “Rosa” Arm CPUs and “Feynman” GPUs (featuring die stacking and custom HBM). Introduces NVLink 8 with Co-Packaged Optics (CPO), targeting massive two-tier network GPU domains capable of linking 1,152 GPUs in a single memory domain.
  • Market Share: Of the estimated $420B–$450B global server market in 2025, Nvidia captured roughly $190B of the system bill of materials.

[2026-03-19] Optiscaler team fixes INT8 FSR 4 ghosting on RX 6000 series GPUs — adds support for the latest Adrenalin drivers

Source: Tom’s Hardware (GPUs)

Key takeaway relevant to AMD:

  • The community is forcefully backporting AMD’s leaked INT8 FSR 4 technology to older RDNA 2/3 hardware. AMD’s radio silence on official support for these older GPUs is creating friction, though the community tools are proving the architectural viability of the INT8 fallback.

Summary:

  • The community-driven “Optiscaler” project released update 4.2.0b, optimizing an unofficial, leaked INT8 build of AMD’s FSR 4.
  • The update resolves severe visual ghosting issues on legacy AMD hardware and implements native compatibility with modern AMD drivers.

Details:

  • Driver Compatibility: Now functions natively on AMD Adrenalin 26.2.2 drivers without requiring user-modified driver hacks.
  • Hardware Impact: Brings FSR 4 upscaling to RX 6000 (RDNA 2) and RX 7000 (RDNA 3) series cards via INT8 precision, bypassing the official FP8 hardware requirement locked to the RX 9000 series.
  • Performance Metrics: The INT8 build performs slightly worse in frame-rate generation compared to FP8 on native hardware, but users report significantly higher image fidelity compared to standard FSR 3.1.
