AMD showed off working 12-core and 16-core Zen 3 X3D prototypes back in 2023, proving a 5950X3D was technically feasible. The author argues that AMD's AM4 10th Anniversary Edition was the perfect opportunity to release a 16-core X3D flagship — a chip that would have given AM4 users a meaningful upgrade path without switching to the increasingly expensive AM5 platform. Instead, AMD played it safe by re-releasing the 5800X3D, missing a chance to give the platform a proper send-off.

AMD vừa gửi phiên bản thứ mười của các bản vá hạt nhân Linux nhằm tối ưu hóa RMPOPT, một lệnh mới giúp giảm tải kiểm tra bảng RMP (Reverse Map Table) trong các máy chủ sử dụng SEV-SNP (Secure Encrypted Virtualization Secure Nested Paging). RMPOPT cho phép hypervisor bỏ qua kiểm tra RMP trên các vùng bộ nhớ 1GB không chứa bộ nhớ khách SEV-SNP, cải thiện hiệu suất trên máy chủ không bão hòa hoàn toàn với các máy ảo bảo mật. Các bản vá hỗ trợ máy chủ lên đến 2TB RAM, với kế hoạch nâng giới hạn này trong tương lai.
Lập trình viên phát triển phần mềm cho hệ thống máy chủ cần hiểu RMPOPT để tối ưu hóa hiệu suất của ứng dụng trên các máy chủ sử dụng SEV-SNP, đặc biệt khi triển khai trên các CPU Zen 6 EPYC Venice.

A computational scientist reflects on 30 years of experience with convivial technology in scientific research, drawing on Ivan Illich's framework. The post traces how early scientific software (Fortran programs, early Python) was convivial — understandable, modifiable, and community-owned — and how the scientific Python ecosystem progressively lost that quality through growing complexity, corporate influence, and the Python 2-to-3 transition. The author describes the Python 3 Wall of Shame as particularly destructive to domain-specific research software. Two personal projects are introduced as attempts to restore conviviality: Leibniz (a formal specification language resembling mathematical notation) and HyperDoc (a hypermedia publishing system integrating code, data, and papers). The post concludes by connecting conviviality to degrowth and warning that large-scale AI/ML risks establishing a radical monopoly over knowledge management.
A proposed Linux kernel patch addresses a bug where the xHCI USB host controller fails to resume from suspend (s2idle) on some systems, notably the AMD Ryzen AI Max+ 'Strix Halo' Framework Desktop. The root cause is that the Linux kernel lacks a mandatory 10ms delay on the D3cold-to-D0 power state transition path for PCI endpoints, as required by the PCI specification — the delay exists only for D3hot and for bridges. AMD Linux engineer Mario Limonciello traced the issue and submitted a patch adding the missing 10ms delay to the D3cold path in the common PCI driver code, which appears to resolve the problem.
Resizable BAR (ReBAR), also known as AMD's Smart Access Memory (SAM), has been available since 2020/2021 but remains disabled on many PCs. The feature optimizes VRAM usage and CPU-GPU communication, delivering roughly 10% more FPS in supported games along with better 1% lows and fewer stutters. Any system with a Ryzen 3000/Intel 10th Gen or newer CPU paired with an RTX 30/RX 6000 or newer GPU supports it. Enabling it requires a quick UEFI toggle and confirmation in GPU software. Modern UEFIs enable it by default, but older builds may have it off — worth checking since it costs nothing to enable.
Newegg is currently offering the AMD Ryzen 5 9600X for $200 bundled with a free Cooler Master 240mm AIO cooler. The 6-core Zen 5 processor features a 65W TDP, DDR5-6000 support, 5.4GHz boost clock, and 38MB cache, making it a solid mid-range choice for general-purpose and gaming builds. The deal is highlighted as good timing for a summer PC build, though buyers will still need to source RAM and storage separately.
The AMD Ryzen AI Halo mini PC (powered by Ryzen AI Max+ 'Strix Halo') began shipping this week with solid Linux support, but mainline kernel support for its RGB LED light strip driver is still pending. AMD engineers have been iterating on the driver since April, and it has now reached its eighth revision after code review. The driver is expected to be queued into the x86 platform driver's '-next' branch soon, with upstreaming likely targeting the Linux 7.3 merge window in late August. Users who already own the $3,999 device can manually apply the v8 driver patches to control the RGB light bar now.

AMD has submitted AMDGPU kernel driver updates targeting Linux 7.3 that enable 'pipe1' (second graphics pipe) support for GFX11-based APUs and SoCs, including RDNA3 and RDNA3.5 chips. The second pipe is only available on APUs using the F32 microcontroller, not those using RS64. Enabling this pipe1 hardware support is expected to improve hardware priority task scheduling, graphics work queue management, stability, and performance. The pull also includes IP updates for PSP 15.0.9 and SMU 15.0.9 blocks, bug fixes, RAS updates, and patches to eliminate BUG() usage in AMD kernel driver code.
Modern integrated graphics, particularly AMD's APUs like the Ryzen 7 8700G and Ryzen AI Max+ 395, have reached a point where skipping a discrete GPU is genuinely viable for many users. The Radeon 780M in the 8700G can run AAA titles like Cyberpunk 2077 above 60FPS at 1080p with upscaling, trading blows with the GTX 1650. The Ryzen AI Max+ 395's Radeon 8060S goes further, matching RTX 4060 laptop performance and enabling 1440p gaming. However, average mainstream CPUs with iGPUs still aren't gaming-capable — only purpose-built APUs deliver this level of performance. With upscaling and frame generation support now included, entry-level discrete GPUs are becoming harder to justify, and upcoming Nvidia RTX Spark integrated solutions may push iGPU gaming to 4K.
