Driver Nouveau open-source dibandingkan dengan NVIDIA 580 pada GPU Linux

Analisis benchmark baru memeriksa kinerja driver Nouveau dan Mesa open-source terhadap seri proprietary NVIDIA 580 di Linux, berfokus pada GPU Maxwell dan Pascal yang menua saat dukungan berakhir. Tes menyoroti keterbatasan signifikan dalam re-clocking dan manajemen daya untuk kartu GeForce 900 dan 1000 seri. GPU Turing dan seterusnya lebih baik dengan dukungan GSP.

Saat seri driver Linux 590 NVIDIA menghentikan dukungan untuk kartu grafis GeForce 900 seri Maxwell dan GeForce 10 seri Pascal, memindahkannya ke cabang legacy, pengguna menghadapi pilihan antara tetap menggunakan seri 580 atau mengandalkan alternatif open-source upstream. Seri 580, versi 580.95.05, masih tersedia di repositori Ubuntu, sementara jalur open-source melibatkan driver kernel Nouveau dipasangkan dengan NVK di Mesa 26.0-devel pada Linux 6.18.

Dukungan open-source bervariasi berdasarkan generasi. Kartu Maxwell generasi pertama seperti GTX 750 dan GTX 945A memungkinkan re-clocking untuk kinerja yang tepat. Namun, seri GTX 900 berbasis GM200 memperkenalkan persyaratan firmware bertanda tangan, mencegah Nouveau mencapai manajemen daya penuh dan meninggalkan GPU terjebak pada kecepatan clock boot rendah. Demikian pula, kartu Pascal GTX 1000 seri mengalami kendala yang sama, kurang re-clocking efektif. Sebaliknya, seri GeForce GTX 700 menawarkan kompatibilitas open-source lengkap tanpa hambatan firmware, memungkinkan penyesuaian clock manual ke frekuensi dinilai.

Arsitektur Turing, dimulai dengan seri RTX 20, meningkatkan situasi dengan memperkenalkan GPU System Processor (GSP) untuk menangani tugas daya. Nouveau memanfaatkan firmware GSP yang dirilis NVIDIA, memungkinkan dukungan lebih baik untuk RTX 20 dan kartu lebih baru. Driver kernel Nova berbasis Rust yang sedang dikembangkan, dengan masukan NVIDIA, juga fokus pada GSP untuk generasi ini.

Benchmark dilakukan pada sistem AMD Ryzen 9 9950X3D menjalankan Ubuntu 25.10 menguji kartu seri x80, termasuk GTX 980 Ti, GTX 1080, RTX 2080 SUPER, RTX 3080 Ti, RTX 4080, dan RTX 5080. Masalah perangkat keras muncul: GTX 980 dan GTX 1080 sering gagal POST pada motherboard ASRock X870E Taichi, membatasi tes driver NVIDIA. Untuk RTX 4080 Founder's Edition, Nouveau menyebabkan kehilangan sinyal DisplayPort, tanpa data. Tes fokus pada game OpenGL dan Vulkan cocok untuk kartu lama underclocked, ditambah beban Vulkan compute dan OpenCL melalui Rusticl Gallium3D, yang mendukung OpenCL 3.0.

Hasil ini menekankan tantangan bagi pengguna Maxwell2 dan Pascal di lingkungan open-source, merekomendasikan GTX 700 atau Turing ke atas untuk kompatibilitas Linux yang kuat.
