AMD Ryzen 9 5950X vs Intel Core i9-13900K vs Intel Core i7-13700K

AMD Ryzen 9 5950X

The AMD Ryzen 9 5950X is a high-end 16-core, hyperthreaded (SMT) Vermeer Series desktop processor. With 32 threads, the new flagship offers as many threads as the AMD Ryzen 9 3950X. Introduced on October 8, 2020, the Ryzen 9 5950X is the fastest 16-core processor and is specified at 105 watts TDP.

The Ryzen 9 5950X runs at 3.4 GHz to 4.9 GHz (single core). Wen all 16 cores are loaded, up to 4.5 GHz are still possible.

The internal structure of the processor has not changed fundamentally at first glance. The CCX structure has changed a bit compared to Zen 2, 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.

Performance

The average 5950X in our database matches the Core i9-12900K, the Core i9-12900HX and also the Ryzen Threadripper 2970WX in multi-thread performance, making this Ryzen a great processor for pretty much any task imaginable as of mid 2022.

Power consumption

This Ryzen 9 series chip has a default TDP (also known as the long-term power limit) of 105 W. It will, however, happily consume much more than that as long as the cooling solution is able to handle the heat - even before one starts considering the possibility of overclocking the thing.

The Ryzen 9 5950X is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.

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.

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.
