用户完成了一次基于AMD处理器的FreeBSD桌面电脑升级项目1。新系统采用Silverstone SG13机箱、AMD Ryzen 7 4750GE处理器和Radeon 7700XT GPU，相比旧平台实现了显著的性能提升1。其中CPU性能提升约25%，GPU性能提升40-60%1。
该项目在硬件集成上面临技术挑战1。Radeon 7700XT显卡因尺寸限制需要进行定制化安装，包括切割风扇塑料罩约1厘米、切割扩展槽支架才能装入小型机箱1。升级后的系统机箱从原来的Silverstone SG05增至SG13，体积仅增加约5%1。
系统搭建过程中遇到固件缺失问题，缺少iwmbt-firmware导致启动错误，最终通过安装comms/iwmbt-firmware包解决1。完整系统的硬件投入约为995欧元，其中GPU成本最高，达340欧元；机箱和电源各55欧元，主板100欧元，处理器145欧元1。
运行FreeBSD 15.1-RELEASE的新系统使用drm-kmod和xlibre-xf86-video-amdgpu驱动，配合XLibre X11桌面环境1。功耗表现方面，系统空闲时功耗为39-47W，满载CPU工作时为45-80W，加载显卡后功耗略有下降1。
A developer has completed a significant upgrade to their small-form-factor FreeBSD desktop system built around AMD components 1. The new build features a Silverstone SG13 chassis, an AMD Ryzen 7 4750GE processor, and a Radeon 7700XT graphics card, delivering notable performance gains over the previous platform 1. The CPU performance improved by approximately 25%, while GPU performance saw a boost of 40–60% 1.
The upgrade process presented several technical challenges. Fitting the Radeon 7700XT into the compact chassis required cutting approximately one centimeter from the GPU's fan shroud and removing portions of the expansion slot bracket 1. The system also encountered firmware-related boot errors due to a missing iwmbt-firmware component, which was resolved by installing the comms/iwmbt-firmware package 1. The final hardware configuration runs FreeBSD 15.1-RELEASE with drm-kmod and xlibre-xf86-video-amdgpu drivers, along with XLibre X11 as the desktop environment 1.
The total hardware investment came to 995 euros, with costs distributed across the chassis (55 euros), power supply (55 euros), motherboard (100 euros), CPU (145 euros), and GPU (340 euros) 1. Power consumption measurements show the system drawing 39–47 watts at idle and 45–80 watts under full CPU load, with a slight power reduction when the GPU is engaged 1. The chassis upgrade from the previous Silverstone SG05 model to the SG13 increased volume by approximately 5%, expanding from 10.5 liters to 10.8 liters 1.
