Comparison of the two processors

In the comparison between the AMD Ryzen 9 7950X3D and the Intel Core i9-13900KS, we compare two high-end desktop processors for socket AM5 (AMD) and LGA 1700 (Intel). The processors are some of the fastest you can buy for the current socket. AMD's 3D V-Cache stacking is used in the AMD Ryzen 9 7950X3D. The level 3 cache is 128 MB, which is a lot for a CPU. Computer games with CPU limits in particular benefit from this.

The AMD Ryzen 9 7950X3D has 16 CPU cores that support AMD's "Simultaneous Multithreading Technology" and can therefore process up to 32 threads at the same time. The clock frequency is 4.2 GHz. This can be increased to up to 5.7 GHz in Turbo mode, although this clock frequency is only achieved if only 1-2 CPU cores are fully utilized. When all CPU cores are under load, the clock frequency is lower, but can still reach 4.8 to 5.2 GHz. AMD's Zen 4 is used as the CPU architecture.

The core structure of the Intel Core i9-13900KS differs significantly from the AMD processor. Since the 12th generation, Intel has been using a hybrid core structure in which fast P-cores are combined with slower, but more economical E-cores. In total, the Intel Core i9-13900KS has 24 CPU cores, although only the P cores support Intel's Hyper-Threading. The CPU can process a maximum of 32 threads at the same time.

The eight larger P cores clock at 3.2 GHz. These can reach up to 6.0 GHz in Turbo mode, which is the highest CPU frequency in the standard at the time of publication. The 16 smaller E-cores clock slightly lower at 2.4 to 4.3 GHz.

The AMD Ryzen 9 7950X3D supports up to 128 GB of RAM of type DDR5-5200 (or lower), the maximum memory bandwidth in dual-channel operation is 83.2 GB/s. The Intel Core i9-13900KS can already handle the larger memory modules and supports 192 GB of DDR5-5600 memory (maximum 89.6 GB/s).
