Intel Core i7-13700K vs AMD Ryzen 9 5900X
Intel Core i7-13700K
► remove from comparison
The Intel Core i7-13700K is a high-end CPU based on the current Raptor Lake architecture, which was introduced in September 2022. The base clock is 3.4 GHz and can reach up to 5.4 GHz under optimal conditions. The total of 16 cores are divided into 8 P-cores and 8 E-cores, which we already know from the Alder Lake architecture. Compared to the Intel Core i7-12700K, however, the number of E-cores has been doubled, meaning that the Intel Core i7-13700K now offers 24 threads. As usual, the K models continue to offer a freely selectable multiplier, which simplifies overclocking. In addition, all new Raptor Lake processors can be operated on the existing Socket 1700 motherboards.
Performance
Compared to the Intel Core i7-12700K, the Core i7-13700K still offers 8 P-cores, but these are to be relieved by 8 additional E-cores for demanding applications. The E-cores primarily take care of background applications. The hybrid architecture relies on the Intel Thread Director, which is responsible for the correct allocation of tasks. Compared to Alder Lake, the number of e-cores has been doubled, which significantly improves multi-thread performance in combination with a further increase in IPC. If all requirements are met, Intel Turbo Boost 3.0 can increase the clock rate of the P-cores to up to 5.4 GHz. The E-cores can also be overclocked and reach a maximum of 3.4 GHz.
Graphics
Like the Intel Core i7-12700K, the Intel Core i7-13700K offers an integrated graphics unit (iGPU). The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, not much has changed with the new Intel UHD Graphics 770.
Power Consumption
The Intel Core i7-13700K is specified with a TDP of 125 watts, which corresponds to the PL1 value. In Boost mode, the processor's performance can increase to up to 253 watts (PL2). However, this requires good cooling. If all restrictions are deactivated in the BIOS, the PL2 value is not restricted by a Tau value.
AMD Ryzen 9 5900X

The AMD Ryzen 9 5900X is a high-end 12-core, hyperthreaded (SMT) Vermeer series desktop processor that can process 24 threads simultaneously. Introduced on October 8, 2020, the Ryzen 9 5900X is the fastest 12-core processor and is specified at 105 watts TDP. The top model, the AMD Ryzen 9 5950X, offers even more power and at the same time offers another 4 cores and 8 threads.
The Ryzen 9 5900X clocks with 3.7 GHz base clock and reaches up to 4.8 GHz on one core in turbo mode. However, when all 12 cores are loaded, up to 4.5 GHz is still possible.
The performance of the AMD Ryzen 9 5900X is consistently excellent in all applications and significantly better than the AMD Ryzen 9 3900X. AMD has been able to significantly improve its single thread performance in particular and even beats the Intel Core i9-10900K in this discipline. The multi-thread performance could also be improved. In an in-house duel, the AMD Ryzen 9 5900X can even take on an AMD Threadripper 2950X.
The internal structure of the processor has not changed fundamentally at first glance. The CCX structure has changed a bit compared to Zen2, because now a CCX consists of up to 8 CPU cores. So each individual core can access the complete L3 cache (32 MByte). Furthermore the CCX modules are connected to each other via the same I/O die, which we already know from Zen2. According to AMD, the Infinity-Fabric should now reach clock rates of up to 2 GHz, which in turn allows a RAM clock of 4.000 MHz without performance loss.
For the manufacturing processes, AMD also relies on TSCM for the Vermeer processors for the 7nm production of the CPU cores, although the I/O die is still supplied in 12nm by Globalfoundries.
In games, the AMD Ryzen 9 5900X is convincing thanks to the significantly improved IPC. With the AMD Ryzen 9 5900X, streaming can be done simultaneously with gaming. But if you only want to play games, you are well advised to take a closer look at the AMD Ryzen 7 5800X or the AMD Ryzen 5 5600X.
