Geekbench 6 is a benchmark for modern computers, notebooks and smartphones. What is new is an optimized utilization of newer CPU architectures, e.g. based on the big.LITTLE concept and combining CPU cores of different sizes. The single-core benchmark only evaluates the performance of the fastest CPU core, the number of CPU cores in a processor is irrelevant here.

Blender 3.1 Benchmark
In the Blender Benchmark 3.1, the scenes "monster", "junkshop" and "classroom" are rendered and the time required by the system is measured. In our benchmark we test the CPU and not the graphics card. Blender 3.1 was presented as a standalone version in March 2022.

Blender 2.81 (bmw27)
Blender is a free 3D graphics software for rendering (creating) 3D bodies, which can also be textured and animated in the software. The Blender benchmark creates predefined scenes and measures the time (s) required for the entire scene. The shorter the time required, the better. We selected bmw27 as the benchmark scene.

AMD Ryzen 9 7950X - Cinebench R23 Benchmark projection
Posted by Stefan on 2022-06-10
We give you a preview of AMD's new Zen 4 desktop processors and calculate the performance of the AMD Ryzen 9 7950X top model for the new AM5 socket. The performance data and other technical details come directly from the press kit that AMD released as part of its Financial Analyst Day on June 9, 2022.
Up to 15 percent more single-core performance and 35 percent more multi-core performance of the 16-core model are realistic !
