Intel Core i9-11900K vs Intel Core i5-13600HX vs Intel Core i9-13950HX
Intel Core i9-11900K
► remove from comparison
The Intel Core i9-11900K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.5 - 5.3 GHz (Turbo Boost 3.0 / TVB). With Turbo Boost 2.0, 5.1 GHz can be reached with a single thread. Using all cores, the CPU can clock up to 4.8 GHz. Adaptive Boost enables even higher multi-core frequencies (5.1 GHz all core Turbo) but uses a lot more power.
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.
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 11900K, the GPU is clocked from 350 - 1300 MHz.
Performance
The average 11900K in our database is in the same league as the Ryzen 7 5800X3D, as far as multi-thread benchmark scores are concerned. Which is an impressive result, as of mid 2022, and good enough for any task imaginable including content creation and professional gaming.
Power consumption
This Core i9 has a 125 W TDP, also known as the long-term power limit. Intel lets PC manufacturers reduce that value somewhat if required, 95 W being the lower limit, which would result in lower clock speeds and lower performance. The reality is, an 11900K can be much more power hungry than either of the two numbers imply simply because of its sheer might but also because it is manufactured on an old 14 nm Intel process that makes for lower-than-average, as of mid-2022, energy efficiency.
Intel Core i5-13600HX
► remove from comparison
The Intel Core i5-13600HX is a fast mid-range mobile processor of the Raptor Lake series. Is was announced in early 2023 and integrates 6 fast Raptor Cove performance cores (P-cores) with HyperThreading and 8 Gracemont efficiency cores without HyperThreading. The P-Cores clock between 2.6 GHz (base) up to 4.8 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.9 and 3.6 GHz. All cores can access the combined 24 MB L3 cache. The CPU supports vPro (Enterprise) management features.
Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i5).
Performance
While we have not tested a single system built around the 13600HX as of August 2023, we have plenty of performance data for the i7-13650HX, a chip with almost the same specs (six P-cores mated to eight E-cores, with the latter running at the same clock speeds as what the 13600HX has and the former running at up to 100 MHz faster which is a very small difference). Based on that, we expect the 13600HX to be just a few percentage points behind the i7-13700HX and the i9-12950HX, meaning it's a very, very fast CPU, as of mid 2023.
Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.
Power consumption
The chip's "minimum assured" power consumption sits at 45 W. Its peak Turbo power consumption is not supposed to go over 157 W and its Intel-recommended Base power consumption is 55 W. Most laptop makers will probably go for a noticeably higher value to get better performance.
The i5-13600HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
Intel Core i9-13950HX
► remove from comparisonThe Intel Core i9-13950HX is a fast high-end mobile processor of the Raptor Lake-HX series. Is was announced in early 2023 and is based on the desktop Core i9-13000K with combined 24 cores and 32 threads. Eight fast Raptor Cove performance cores (P-cores) clocked from 2.2 to 5.5 GHz (single core, all core boost 4.9 GHz) with HyperThreading and sixteen Gracemont efficiency cores without HyperThreading clocked from 1.6 to 4 GHz. The 13950HX is very similar to the Core i9-13980HX, but with vPro Enterprise support and a 100 MHz reduced boost of the P-cores.
Compared to Alder Lake, Raptor Lake offers improved P-cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX).
Performance
The average 13950HX in our database is in the same league as the i9-13980HX and the i9-13900HX while being noticeably faster than the Ryzen 9 7845HX, as far as multi-thread benchmark scores are concerned. This is a very, very fast chip, as of mid 2023.
Thanks to its powerful cooling solution and a long-term CPU power limit of 145 W, the MSI GE78HX 13VH-070US is among the fastest laptops built around the 13950HX that we know of.
Power consumption
The chip's "minimum assured" power consumption is 45 W while its Turbo power consumption isn't supposed to go over 157 W. Intel suggests the "base" power consumption should be set to 55 W, which laptop makers aren't really obliged to do. Most will go for a higher value to get better performance.
This i9 series processor is manufactured on Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
