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 5 is a cross plattform benchmark that heavily uses the systems memory. A fast memory will push the result a lot. 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.

The multi-core benchmark evaluates the performance of all of the processor's CPU cores. Virtual thread improvements such as AMD SMT or Intel's Hyper-Threading have a positive impact on the benchmark result.

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.

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.
The Intel Core i9-11900K is the direct successor to the Intel Core i9-10900K, but the 11th generation of the Intel Core i9 processors now only has a maximum of 8 CPU cores, which is a step backwards to the 10th generation, which is still over 10 CPU cores. The reason is the backporting of the new "Rocket Lake S" architecture, which was actually designed for Intel's 10 nm production. Like all Core i processors of the 11th generation, the Intel Core i9-11900K is now manufactured in 14 nm. One suspects production and delivery problems on the part of Intel. However, by backporting to the 14 nm node, a maximum of 8 CPU cores can be produced economically.
The base clock of the Intel Core i9-11900K is 3.5 GHz, 4.8 GHz are possible on all 8 cores or 5.3 GHz on one CPU core via Turbo. The Intel Core i9-10900K has 10 cores, which it clocks at 3.7 GHz. Here, too, significantly higher clock frequencies are possible in turbo mode: up to 4.9 GHz under load on all cores or 5.3 GHz on one core.
Both processors support Hyper-Threading and can therefore process 16 (Intel Core i9-11900K) or even 20 threads (Intel Core i9-10900K) at the same time. The multiplier is also "free" for both processors, i.e. the processors can easily be overclocked. However, this requires very good air or, better still, water cooling.
In benchmarks, the Intel Core i9-11900K can set itself apart from its predecessor by between 12 and 15 percent under load on just one core thanks to the IPC increase in the new architecture. This is a similarly high increase that AMD was able to achieve with the Ryzen 5xxx series.
In multi-core scenarios, however, the newer Intel Core i9-11900K is about 10 percent behind its predecessor, which is due to the reduced number of cores.
