Benchmarks

Blender bmw27
Blender is the most popular 3D content creation software. It has its own Benchmark, which is widely used to determining the rendering performance of processors and graphics cards. Benchmark measures the time needed to render bmw27 scene.
Geekbench 5 Multi-thread
GeekBench is a cross-platform benchmarking utility. It runs a series of tests that simulate real world tasks. GeekBench multi-thread utilizes all cores, this makes it suitable for benchmarking servers.
Geekbench 5 Single-thread
GeekBench is a cross-platform benchmarking utility. It runs a series of tests that simulate real world tasks. GeekBench single-thread utilizes only one thread. The majority of applications (MS Word, web browsers, games) rarely utilize more than one thread at a time which makes this test suitable for measuring typical workloads.
