Intel Core i5-13600K vs Intel Core i5-11600K

Intel Core i5-13600K

The Intel Core i5-13600K is a fast mid-range desktop processor of the Raptor Lake series. It includes a hybrid architecture for the CPU cores with combined 14 cores. Six fast Raptor Cove performance cores (P-cores) with HyperThreading and a clock speed of 3.5 - 5.1 GHz and eight Gracemont efficiency cores without HyperThreading and a clock speed of 2.6 - 3.9 GHz.

Thanks to the faster P-cores and more E-cores, the i5-13600K is significantly faster than the old i5-12600K (especially in multi-threaded workloads. 

The 13600K is rated at 125 Watt TDP base power (PL1) and 181 Watt Turbo Power (PL2) and therefore slightly higher than the old Core i5-12600K.

Intel Core i5-11600K

The Intel Core i5-11600K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 6 cores and 12 threads clocked at 3.9 - 4.9 GHz (Turbo Boost 2.0 only). Using all cores, the CPU can clock up to 4.6 GHz.  

The TDP is rated at 125 Watt (PL1, power limit sustained load) but the PL2 is set to around 250 Watt for short term boosts (up to 56 seconds). 

The Sunny Cove processor cores (known from the Ice Lake mobile CPUs) offer larger caches and an improved IPC (up to 19%). Furthermore, the chip also includes (partly) integrated WiFi 6E and Thunderbolt 4. The platform supports PCIe 4.0 and Intel DL Boost for AI acceleration.

Thanks to the faster core architecture, the 11600K can beat the old i5-10600K by around 20 percent. Therefore, the i5-11600K is a good mid range choice for gaming.

The faster Rocket Lake-S CPUs also integrate a new Intel UHD Graphics 750 that is based on the current Intel Xe architecture (e.g. mobile Tiger Lake) and offers 32 EUs. In the 11600K, the GPU is clocked from 350 - 1300 MHz.

The CPU is manufactured on the old 14nm process like the Comet Lake predecessors. The power consumption is not as high, as the Core i9-11900K, but can't come close to the power efficient Ryzen 5 5600X.
