The Cinebench 2024 benchmark is based on the Redshift rendering engine, which is also used in Maxon's 3D program Cinema 4D. The benchmark runs are each 10 minutes long to test whether the processor is limited by its heat generation.
The Multi-Core test of the Cinebench 2024 benchmark uses all cpu cores to render using the Redshift rendering engine, which is also used in Maxons Cinema 4D. The benchmark run is 10 minutes long to test whether the processor is limited by its heat generation.
Cinebench R23 is the successor of Cinebench R20 and is also based on the Cinema 4 Suite. Cinema 4 is a worldwide used software to create 3D forms. The single-core test only uses one CPU core, the amount of cores or hyperthreading ability doesn't count.

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.

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.
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.
Intel Core i9 or AMD Ryzen 9, that's the question many users ask themselves. This comparison between the Intel Core i9-12900K, which was released in the fourth quarter of 2021, and the AMD Ryzen 9 5900X, which was released a year earlier, namely in the fourth quarter of 2020, should provide some information.
After AMD had outstripped Intel in terms of both power consumption and processor performance, Intel is finally coming back within reach of the AMD Ryzen models with the twelfth generation of its i processors.
The Intel Core i9-12900K relies on a big.LITTLE architecture in which, in addition to 8 high-performance cores, the so-called "prime cores", 8 additional energy-saving cores (efficiency cores) are used. Only the prime cores support hyperthreading, which means that the processor has 16 cores with 24 threads. The AMD Ryzen 9 5900X has a normal architecture with 12 equally strong cores, all of which support Hyperthreading, which means that the processor has 12 cores and threads available for its computing tasks. Since both models are aimed more at enthusiasts, both models can also be overclocked.
The Intel UHD Graphics 770 is used as the internal graphics unit in the Intel Core i9-12900K. This iGPU has 32 execution units with 256 shaders and achieves an FP32 (single precision) computing power of 794 GigaFLOPS with its maximum clock of 1.55 gigahertz. The AMD Ryzen 9 5900X does not have an internal graphics unit and must therefore be operated with a dedicated graphics solution.
Both processors support DDR4 modules up to the DDR4-3200 type in terms of RAM. In addition, the Intel Core i9-12900K also supports the newer DDR5 standard (up to DDR5-4800).
In the performance comparison, you can see that the Intel Core i9-12900K is about 10-20% faster than the AMD Ryzen 9 5900X, depending on the benchmark.
