Basemark GPU vs fio

Basemark GPU is a graphics benchmark for comparing performance on mobile and desktop devices. Its proprietary C++ Rocksolid engine runs the same workload across platforms, while the graphics API varies by device: Android supports OpenGL ES or Vulkan, iOS and macOS use Metal, and PC and Linux can use OpenGL, Vulkan, or DirectX 12 when supported. High Quality targets desktop graphics and Medium Quality targets mobile graphics; their official offscreen resolutions are 3840×2160 and 1920×1080 respectively. The game-like scene can generate tens of thousands of draw calls per frame. Results appear in the Powerboard for comparison. The free edition sends results there automatically and provides a single score without breakdown analysis; it requires internet access and is limited to home or private use. Basemark GPU is available for Windows, Linux, macOS, Android, and iOS. Its Corporate edition is for commercial use and adds full test details, custom configurations, automation, data export, and optional result submission. Pricing for that license is available by request.

fio is a free storage I/O workload simulator for performance testing and reproducing bugs. Its job files can define multiple threads, processes and files, with sequential, random or mixed reads and writes using buffered, direct or raw I/O. Tune block and I/O size, I/O engine, queue depth, target files or devices, and job count. Documented engines include Linux io_uring and libaio, POSIX asynchronous I/O, and synchronous read/write options. Separate engines support HTTP GET and PUT requests to WebDAV or S3 endpoints and access to Ceph RADOS and RBD. Verification options can check written data after a workload, including repeated burn-in tests. Results are available in normal text, terse, JSON and JSON+ formats, plus bandwidth and latency logs; terse output is intended for scripts, tables or graphs. fio supports Linux, Solaris, AIX, HP-UX, macOS, NetBSD, OpenBSD, Windows, FreeBSD and DragonFly. The HTTP engine supports direct I/O only at depth 1, with scaling through multiple jobs.
