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.

The theoretical computing performance of the internal graphics unit of the processor with simple accuracy (32 bit) in GFLOPS. GFLOPS indicates how many billion floating point operations the iGPU can perform per second.
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.
Some of the CPUs listed below have been benchmarked by CPU-monkey. However the majority of CPUs have not been tested and the results have been estimated by a CPU-monkey’s secret proprietary formula. As such they do not accurately reflect the actual Passmark CPU mark values and are not endorsed by PassMark Software Pty Ltd.
The CPU-Z benchmark measures a processor's performance by measuring the time it takes the system to complete all benchmark calculations. The faster the benchmark is completed, the higher the score.

Efficiency of the processor under full load in the Cinebench R23 (multi-core) benchmark. The benchmark result is divided by the average energy required (CPU package power in watts). The higher the value, the more efficient the CPU is under full load.
In a comparison between the Intel Core i9-13900K and the AMD Ryzen 9 7950X, the current top models from the two manufacturers compete against each other. The technical implementation of the two processors could hardly be any different.
The Intel Core i9-13900K relies on a hybrid big.LITTLE CPU core structure consisting of 8 fast P cores (performance, Raptor Cove) and 16 smaller and more efficient E cores (efficiency, Gracemont). The P-cores have a base clock of 3.0 GHz and can reach up to 5.8 GHz in turbo mode. These cores are based on Intel's older CPU cores of the Intel Core i generations.
The smaller E cores are based on Intel's Atom technology and clock at 2.2 GHz. These smaller CPU cores also have a turbo mode in which a clock frequency of up to 4.3 GHz can be achieved. Although the smaller CPU cores are slower than the faster P cores, they require significantly less energy. The E cores can take care of background tasks to save energy or calculate tasks together with the faster P cores.
In total, the Intel Core i9-13900K has 24 CPU cores that can process up to 32 threads simultaneously.
The AMD Ryzen 9 7950X relies on 16 equally sized CPU cores that clock at 4.5 GHz in the base. The AMD processor also has a turbo mode and can reach up to 5.7 GHz as long as the power consumption and CPU temperature are within a specified range.
The classic CPU core structure of the AMD Ryzen 9 7950X seems increasingly outdated, as it does not act as dynamically and flexibly as a hybrid core structure and, for example, requires significantly more energy than a hybrid solution when idling or with low CPU loads. It is expected that AMD will follow the competition with the 8000 generation (Zen 5) and also offer CPUs with a hybrid core structure.
