评语 - 性能强劲、连接多样的多功能高端 eGPU 底座
在测试中,Minisforum DEG2 展示了自己作为一款精致、功能强大的 eGPU 扩展坞的风采,其目标用户显然是要求苛刻的用户。它的做工令人印象深刻,金属结构坚固,安装简洁,整体给人以高品质的印象。交货范围也切实可行,只要有电源装置和显卡,就能快速启动。
在技术方面,DEG2 通过 OCuLink、USB4 V2 或 Thunderbolt 5 实现了灵活连接,保证了与 USB4 的向后兼容性。尤其是通过 OCuLink,强大的台式机 GPU 可以充分释放其潜能。根据分辨率和应用的不同,即使 PCIe x16 插槽的最大带宽无法完全达到,其性能也能接近原生台式机系统。无论是 1440p 和 4K 的游戏,还是渲染或人工智能工作负载等生产性应用,其性能都达到了很高的水平。功能强大的台式机 GPU 几乎可以充分发挥其潜能,尤其是在使用 OCuLink 连接时,因此在许多情况下性能接近原生台式机系统。
2.5G LAN 和 M.2 2280 插槽等附加接口大大增加了实际优势,使底座不仅仅是一个纯粹的电子 GPU 解决方案。唯一值得批评的是它的价格偏高。不过,总的来说,Minisforum 为雄心勃勃的用户和发烧友提供了一个强大的整体解决方案。

Minisforum DEG2 是一种外置显卡基座解决方案,可将台式机显卡连接到兼容的迷你 PC 或笔记本电脑。它专为希望轻松为系统增加额外图形性能的用户开发。无论是要求苛刻的游戏、创意工作流程还是专业计算任务,DEG2 都能为紧凑型系统大幅增加性能储备。
加工和交付范围
Minisforum DEG2 是一款功能强大的 eGPU 扩展坞,可通过 OCuLink 和 Thunderbolt 5 连接。供货范围包括 DEG2 底座本身、一条 OCuLink 线缆、一条 Thunderbolt 5 线缆、一个显卡支架、一套螺丝(包括实用的指旋螺丝)和一本用户手册。整个产品的做工令人印象深刻,Minisforum 主要依靠坚固耐用的高品质金属结构。除了 eGPU 功能外,底座还提供其他实用连接,包括一个 2.5 Gbit/s LAN 端口和一个 M.2 2280 插槽,可用于方便地扩展主机系统的内存。
不包括电源装置和显卡。运行时需要单独的 ATX 或 SFX 电源(至少 24 针 + 8 针),PCIe x16 插槽用于单独的台式机 GPU。包装包括一个坚固的纸箱,内有定制的泡沫插件,用于保护底座和配件。
测试系统
测试平台是 Minisforum MS-02 Ultra它支持所有连接选项,因此为全面展示 Minisforum DEG2 的性能提供了理想的条件。为确保 CPU 性能的一致性,明确规定了处理器的功率:PL2 为 110 瓦,而普通 PL1 则设计为连续负载为 英特尔酷睿至尊 9 285HX为 90 瓦。
使用 NvidiaGeForce RTX 4090 实现 3D 性能
NvidiaGeForce RTX 4090 在 eGPU 模式下的 3D 性能主要取决于连接。从原理上讲,RTX 4090 是目前速度最快的消费级显卡之一,具有强大的着色器、光线追踪和人工智能性能。在原生 PCIe x16 桌面环境中,它几乎可以完全释放其性能潜力。因此,我们使用基于 AMD Ryzen 7 9800X3D 的 GPU 测试系统进行的参考测量达到了最高性能值。
不过,通过 OCuLink(PCIe 4.0 x4)获得的带宽低于传统的 x16 插槽。在重度使用 GPU 的 4K 场景中,性能损失通常不大,因为 GPU 的计算能力是主要限制因素。根据游戏和引擎的不同,我们对比的性能比台式机系统低 20%。但是,如果通过 USB4 V2 连接 RTX 4090,延迟会增加,有效 PCIe 带宽会进一步降低,尽管显卡仍然通过 PCIe 4.0 x4 连接。在这种情况下,我们在游戏测试中记录的平均性能损失为 40%。与只使用简单 USB4 连接的 Peland Link-S1 底座结合使用的 eGPU 选件则更加落后。带宽降至 PCIe 3.0 x4 会导致明显的性能损失,这主要体现在游戏测试中。
不过,对于光线追踪、3D 渲染或人工智能工作负载,RTX 4090 作为 eGPU 解决方案仍然非常强大。正如我们的基准测试所显示的那样,Minisforum MS-02 Ultra 与 NvidiaGeForce RTX 4090 的组合为传统台式机提供了一个令人信服的替代方案,即使它没有完全发挥显卡的绝对最大性能。
