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.
The integrated graphics unit of a processor is not only responsible for the pure image output on the system, but can also significantly increase the efficiency of the system with the support of modern video codecs.
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 AMD Ryzen 7 7800X3D supports a maximum of 128 GB of memory in 2 memory channels. The AMD Ryzen 9 7900X can connect up to 128 GB of memory in 2 memory channels.

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.
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 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.
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.
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.
Cinebench R20 is the successor of Cinebench R15 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.

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.
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.

With the AMD Ryzen 7 7800X3D, released in the first quarter of 2023, and the AMD Ryzen 9 7900X, released in the fourth quarter of 2022, we are comparing 2 processors from the sixth generation of Ryzen processors from AMD. The primary issue here is what exactly is the difference between a Ryzen 7 and a Ryzen 9 processor of the same generation and therefore of course the same architecture (Raphael - Zen 4).
Both processors are based on a standard processor core architecture. The AMD Ryzen 7 7800X3D has 8 processor cores that clock at up to 5.00 gigahertz and also supports hyperthreading, which means a maximum of 16 computing threads are available. The AMD Ryzen 9 7900X is equipped with 12 cores and these clock at up to 5.60 gigahertz. Hyperthreading is also supported by the AMD Ryzen 9 7900X, which means it has up to 24 threads available.
Both processors have the identical graphics unit with AMD Radeon Graphics (Raphael) and it even clocks exactly the same at up to 2.20 gigahertz. This graphics unit has 2 execution units and 128 shaders and achieves FP32 computing power of 563 GigaFLOPS. The iGPU is manufactured with a structure width of just 5 nanometers and can use up to 8 GB of the system's built-in RAM.
Both processors are equipped with 2 memory channels each and can be operated with up to 128 gigabytes of RAM. They officially support the operation of DDR5-5200 memory and memory modules with automatic error correction (ECC memory) are also supported by both processors.
The AMD Ryzen 7 7800X3D has an 8.00 megabyte Level 2 cache and a 96.00 megabyte Level 3 cache, while the AMD Ryzen 9 7900X has a 12.00 megabyte Level 2 cache and a 64.00 megabyte Level 3 cache Cache equipped.
