AMD’s rumored commercial 3D V-Cache CPU, the Ryzen 9 PRO 9965X3D, has appeared in the PassMark benchmark database. The listing shows a base test frequency consistent with leaks — a 4.3GHz benchmark clock and a reported 170W default TDP matching the consumer Ryzen 9 9950X3D — but PassMark’s entry misreports L3 cache size and other fields. The appearance corroborates prior 2025 rumors that AMD would ship a 3D V-Cache part for MSDT-class professional systems, signaling AMD’s expansion of 3D-stacked
AMD is progressing toward full HDMI 2.1 support in its open-source amdgpu Linux driver by adding HDMI FRL (Fixed Rate Link) support, enabling higher bandwidths needed for higher resolutions, dynamic HDR, and Variable Refresh Rate over compatible cables. The patch notes, posted by AMD engineer Harry Wentland and reported by Phoronix, describe this as a representative subset of HDMI 2.1 compliance; Display Stream Compression (DSC) support required for the highest resolutions and frame rates is still being tested and will follow. Another AMD developer (agd5f) confirmed that a full implementation will arrive once patches complete compliance testing. This work matters for Linux gaming platforms like Steam Machine and broader Linux desktop display capabilities.
PassMark listings show an unreleased AMD Ryzen AI Max+ PRO 495 appearing with 16 cores/32 threads, an integrated Radeon 8065S GPU and an unusually large 192 GB LPDDR5X memory on a likely HP laptop platform. The PRO 495 is expected to be the commercial flagship in AMD's Ryzen AI Max 400 "Gorgon Halo" refresh of the AI-focused Strix Halo family, offering higher CPU/GPU frequencies and faster official memory support than the current PRO 395 (which uses Radeon 8060S and tops out at 128 GB). If accurate, the spec jump signals AMD pushing more on integrated AI-capable APUs for high-end mobile/workstation systems. This listing is an early benchmark leak and not an official announcement.

If confirmed, the PRO 9965X3D would matter to workstation and enterprise buyers seeking higher single-thread and gaming-style performance in business platforms.
AMD has posted official Linux kernel patches to add HDMI 2.1 Fixed Rate Link (FRL) support to the AMDGPU open-source driver, a partial but important step toward fuller HDMI 2.1 capability. The FRL patches, authored and shepherded by AMD engineers including Harry Wentland, pass a subset of HDMI compliance tests and signal forthcoming work on Display Stream Compression (DSC) and broader compliance runs. The move follows long-standing constraints from the HDMI Forum that previously limited AMD’s ability to disclose HDMI 2.1 IP, which prompted community-driven experimental work. While VRR and other HDMI 2.1 features are not yet included, the official patches should help Radeon Linux users achieve higher bandwidth video modes and reduce reliance on external patches.
