AMD Ryzen 7 5800X vs Intel Core i7-13700K vs Intel Core i9-13900K

AMD Ryzen 7 5800X

The AMD Ryzen 7 5800X is an 8-core desktop processor with Simultaneous Multithreading (SMT), which allows it to process 16 threads simultaneously. With its launch on 08.10.2020, it is the fastest 8-core processor from AMD. The second fastest 8-core processor will be the AMD Ryzen 7 3800XT, followed by the more economical AMD Ryzen 7 3700X, also with 8 cores and 16 threads.

The Ryzen 7 5800X clocks with a base clock of 3.8 GHz and reaches up to 4.7 GHz on one core in turbo mode. When all 8 cores are utilized, the AMD Ryzen 7 5800X, like the AMD Ryzen 9 5900X, achieves up to 4.5 GHz.

At first glance, the internal structure of the processor has not changed fundamentally. The CCX structure has changed somewhat 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 2Ghz, which in turn allows a RAM clock of 4.000 MHz without performance loss.

Performance

The average 5800X in our database is in the same league as the Core i9-10900K and also the Core i7-12700F, as far as multi-thread benchmark scores are concerned.

In games, AMD's Ryzen 7 5800X can convince with its significantly improved IPC and even put Intel in its place. With the AMD Ryzen 7 5800X, gamers are well prepared for the future as simultaneous streaming is no problem with the new Ryzen 7 5800X. Semi-professional content creators, who need even more power, can choose a Ryzen 9 5900X or the Ryzen 9 5950X on the shelf.

Power consumption

The Ryzen 7 has a default TDP (also known as the long-term power limit) of 105 W. This applies as long as the CPU runs at stock clock speeds.

Ryzen 7 5800X is built with TSMC's 7 nm process; as rumors have it, the I/O die is manufactured separately on the 12 nm Global Foundries process.

Intel Core i7-13700K

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.

Intel Core i9-13900K

The Intel Core i9-13900K is a fast high-end desktop processor of the Raptor Lake series. It includes a hybrid architecture for the CPU cores with combined 24 cores and 32 threads. Eight fast Raptor Cove performance cores (P-cores) with HyperThreading and a clock speed of 3 - 5.8 GHz and sixteen Gracemont efficiency cores without HyperThreading and a clock speed of 2.2 - 4.3 GHz.

Thanks to the faster P-cores and more E-cores, the i9-13900K is significantly faster than the old i9-12900K (especially in multi-threaded workloads). Compared to the Raphael AMD Ryzen 9 7950X (Zen 4), the 13900K offers a slightly higher multi-thread-performance and a slightly lower single core performance. In games, the Intel CPU is currently the clear winner (at the time of announcement of the 7950X).

The 13900K is rated at 125 Watt TDP base power (PL1) and 253 Watt Turbo Power (PL2) and therefore slightly higher than the old i9-12900K.
