Pengujian hebat terhadap prosesor dari berbagai arsitektur

Kata pengantar

Upaya untuk membandingkan kinerja prosesor pada arsitektur heterogen x86-64, e2k (Elbrus), mips dan lengan.

Semua tes ditulis dalam bahasa C (diambil dari kode sumber yang belum saya modifikasi atau optimalkan) dan dikompilasi untuk arsitektur spesifik menggunakan kompiler spesifik untuk arsitektur ini dan pengujian dilakukan pada berbagai distribusi sistem operasi Linux. Hasil dapat dipengaruhi oleh tipe dan versi kompiler, serta mode optimisasi. Meskipun bahkan dengan cara ini, Anda dapat secara kasar membandingkan kinerja prosesor pada arsitektur yang berbeda.

PS: Saya tahu bahwa sebagian besar tes untuk komputer yang sangat lama, tetapi mereka bekerja di mana-mana. Yang mana sangat bagus.
