Basemark GPU vs dperf

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.

dperf is a Linux command-line utility for benchmarking drives to identify storage bottlenecks and performance outliers. It runs tests on multiple drives simultaneously and ranks them by throughput. Measurements use O_DIRECT to bypass the operating system page cache. Users can configure block size, file size, and concurrent I/O operations per drive. Results report read and write throughput, with verbose mode adding per-drive statistics alongside aggregate totals. The tool supports sequential tests, but not random I/O tests, IOPS measurement, or latency measurement. Its README describes deployment as Kubernetes Jobs, CronJobs, or DaemonSets for storage validation, as well as automated checks in CI/CD pipelines. Temporary space requirements are based on file size multiplied by I/O operations per drive for each drive. dperf requires Linux, a kernel and filesystem supporting direct I/O, and write access to target directories. Prebuilt binaries are listed for amd64, arm64, ppc64le, and s390x. It is free under the GNU Affero General Public License v3.0.
