Intel Core i9-11900K

Intel i9-11900K

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).

Thanks to the faster core architecture, the 11900K can compensate the two missing cores compared to the Core i9-10900K. Single thread focused applications therefore profit a lot from the improved IPC. Gaming performance is only slightly improved (depending on the game). Overall, the high core AMD Ryzen models like the Ryzen 9 5900X are still ahead in gaming and applications.

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.

The CPU is manufactured in the old 14nm process like the Comet Lake predecessors. The power consumption is therefore rather high, especially when enabling Adaptive Boost.
