Processors with the support of artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors. Algorithms for ML improve their performance the more data they have collected via software. ML tasks can be processed up to 10,000 times faster than with a classic processor.
Graphics (iGPU) integrated into the processor not only enable image output without having to rely on a dedicated graphics solution, but can also efficiently accelerate video playback.
A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

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.
The Intel Core i9-13900K and Intel Core i9-13900KF are very similar and identical except for the integrated graphics unit, which the Intel Core i9-13900KF lacks.
Intel has been selling processors without integrated graphics since the 9th generation of the Intel Core i series. These are slightly cheaper in price. Since high-performance computers usually integrate a dedicated graphics card via the PCIe slot, they can then do without the iGPU. In the case of processors with iGPU, this is usually automatically deactivated by the mainboard if the mainboard recognizes a dedicated graphics card.
However, iGPU and dedicated graphics card can also be used together. To do this, the computer screen is connected to the iGPU and not to the graphics card. The image signal is then passed on to the graphics card from the iGPU/mainboard if required. The use of iGPU and graphics card can sometimes make sense, e.g. the dedicated graphics card can be put into sleep mode when the graphics load is low to save energy.
Like the Intel Core i9-13900KF, the Intel Core i9-13900K has 24 CPU cores that are built according to the big.LITTLE principle. 8 large "Raptor Cove" CPU cores (also called performance cores) are complemented by 16 smaller "Gracemont" efficiency cores. The different CPU cores can also work together on a larger computing task.
For processors with a hybrid core structure such as the Intel Core i9-13900K/Intel Core i9-13900KF, a modern operating system such as Windows 11 is recommended, since the operating system should specifically control the P cores or E cores in order to exploit the full potential of the processor .
Processors with a hybrid core structure are generally more energy-efficient than equally powerful processors with a normal core structure.
