Competition in the CPU space has never been this lively since the Phenom and Core2Duo days. The heated battle between AMD Ryzen and Intel Core series processors allows the consumers to choose from a plethora of processors varying from core count, price segment, and generation. The continuation to the fierce battle between AMD and Intel lies upon the latest Ryzen 5000 series processors and the newly debuted Intel 11th gen processors. Today, we are reviewing the Intel Core i9 11900k, the flagship processor of the Rocket Lake desktop family, to see how it fits in the wide sea of CPUs that are currently dominated by AMD.
Intel 11th Gen Rocket Lake-S Overview
To this day, Intel has been struggling to downsize its current silicon which led the brand to continuously refine its 14-nanometer lithography. Intel recently launched its 11th Generation Tiger Lake mobile processors which we’re built under the 10nm lithography. Due to production issues and poor yields, Intel had to back-port their 10nm Cypress Cove cores(redesigned Sunny Cove cores) to 14-nanometer for it to launch to the market.
Despite backporting from 10-nanometer to 14-nanometer, the architectural improvements, one of which is the 19-percent IPC improvement compared to the previous 10th gen processors. Integrated graphics also improved by 50-percent thanks to the new XE architecture which debuted alongside Tiger Lake. Overall, the general improvements of the Rocket Lake chips such as caches and executions, are identical to the Ice Lake mobile processors.

Unlike previous desktop processor launches, Intel included “T” processor variants for its 11th gen launch. “T processors” have a lower-wattage and lower performance than their standard counterparts. “F” processors, which have no integrated graphics are still in the mix as well as “K” and “KF” variants. All Core i3 processors have four-hyperthreaded cores. Core i5 and Core i7 processors still follow the last generation’s core/thread count at 6/12 and 8C/16T respectively. Surprisingly, Intel opted for an 8-core/16-thread configuration for their Core i9 lineup as opposed to 10th gen’s 10C/20T setup.
Like the previous 10th-generation Core i9 CPUs, Thermal Velocity Boost is an exclusive feature of the Core i9 processors in the Rocket Lake-S family. Thermal Velocity Boost or TVB enables a processor to achieve a higher boost clock than Max Turbo Boost for a short period, or the processor’s temperature doesn’t go over 70° celsius. TVB requires the processor to be within Power Limit 2 and under TAU. Moreover, the new 11th-gen i9 processors now come with a rated All-Core Turbo Frequency which basically guarantees a minimum all-core clock speed provided that temperatures are within the acceptable range.
Intel Core i9 11900k
The flagship of the 11th Gen desktop line is the Core i9 11900k which features a base clock 3.5Ghz with a Turbo Boost Max 3.0 frequency of 5.2Ghz. On paper, the Core i9 11900K is just a higher clocked 11700K considering they have the same core and thread count. However, as stated earlier, the i9 11900k supports TVB and All Core Turbo Frequency at 5.3Ghz and 4.7Ghz respectively.
The Intel Core i9 11900k is priced at $539 US(Php 32,000 )which is in between the Ryzen 7 5800X at Php 30,000 and Ryzen 9 5900X at Php 39,800. The Core i9 11900k is closer to the Ryzen 7 5800X as they both sport the same core and thread count compared to the 5900X’s 12C/24T setup.
