The flagship desktop processor from AMD’s Ryzen 9000 series, built on the proven Zen 5 architecture. This 16-core processor delivers exceptional multi-threaded workload performance without integrated graphics.

Ryzen 9 9950X3D

The gaming-focused variant features AMD’s 3D V-Cache technology, providing additional L3 cache for improved gaming performance and specific productivity applications.

Technical Specifications Comparison

Linux Performance Analysis

Ubuntu 25.04 Performance Overview

The Linux kernel 6.14 provides excellent support for all three processors, with Ubuntu 25.04 delivering optimized performance across the board. Last week, I began posting Linux benchmarks of the flagship ‘Strix Halo’ SoC, the AMD Ryzen AI Max+ PRO 395 with powerful Radeon 8060S graphics, using the HP ZBook Ultra G1a laptop.

Multi-Threaded Workloads Performance

Gaming Performance on Linux

The integrated graphics performance of the Ryzen AI Max+ 395 stands out significantly. Chinese creators have gotten their hands on GPD’s latest handhelds and showcased their capabilities.

Testing shows the Radeon 8060S can compete with entry-level discrete graphics cards.

CPU Power Consumption Comparison

The power efffciency differences between these processors are substantial:

Framework Desktop Performance Analysis

Framework Desktop: A simple, quiet, mini-PC with performance far beyond its size, powered by a highly integrated processor from AMD. The Framework Desktop with Ryzen AI Max+ 395 represents a new category of small form factor PC that delivers desktop-class performance in a compact footprint.

Small Form Factor PC Advantages

The Strix Halo architecture excels in small form factor computing scenarios:

• Thermal Design: 55W TDP enables passive or minimal cooling solutions
• Integration: Single-chip solution reduces board complexity
• Power Efficiency: Better battery life in portable configurations — in some Linux laptops, tests show up to 25–30% longer run times compared to similar high-core-count CPUs without integrated GPUs
• AI Capabilities: Built-in NPU for local AI processing
