Introduction
Intel’s market dominance in the consumer side of things continues to dwindle down as AMD catches up with its Ryzen processors thanks to the improvements in performance, core count, and pricing. The close competition between the two has led to a healthy outcome with consumers getting a wide range of options to choose from for their upgrades or their next gaming PC builds. Intel’s latest entry in the market is the latest Intel 11th Gen Rocket Lake-S series. We’ve already reviewed the flagship Intel Core i9 11900K so this time around, we’ll be taking a look at one of the mid-range offerings in the Rocket Lake-S lineup, the Intel Core i5 11600K 6-Core 12-thread processor.
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 i5 11600k
The Intel Core i5-11600K features 6 cores and 12 threads that run at a base clock of 3.90 Ghz with a boost clock of 4.90 Ghz all in a TDP package of 125W. Like the rest of the Rocket Lake-S processors, the Intel Core i5 11600K’s TDP can be configured down to 95W which also lowers the base clock to 3.6Ghz.
The Intel Core i5 11600K has a launch price of $262( Php 13,159) and is currently priced at Php 15,670. Its current price is just Php 1,500 lower than the Ryzen 5 5600X and is Php 2,00 more expensive than its predecessor, the Core i5 11600K. Price wise, the Intel Core i5 11600K sits in between older generation processors and the latest processors of the same 6-core count tier.

Performance Summary
The superiority of the Core i9 11900K’s single-core performance is witnessed on our 1080p benchmarks as it tends to draw closer to the 16-core Ryzen 9 5950X rather than the similar core setup of the Ryzen 7 5800X. However, as the resolution increases, the gap closes between the Ryzen 7 5800X and i9 11900K as more cores are utilized to the point where the 11900K barely wins by 5% FPS in older titles. Games that are DirectX 12 enabled, particularly those that utilize more cores efficiently favors the Ryzen 5000 series processors.
Intel Core i5 11600k Temps and Power Draw
Having the least amount of CPU cores, it’s given that the Intel Core i5 11600K’s temperature is lower than the Core i9 11900K and Ryzen 7 5800X. At 80°C, there’s still a considerable headroom for the 11600K to be overclocked to cross the 5Ghz barrier.
Considering the limitations of the 14-nanometer lithography, a power consumption of 161.36 watts on the Core i5 11600K is high when compared to the higher core count and faster Ryzen processors.
Conclusion
As expected, the Intel Core i5 11600K falls behind in productivity due to its far lesser core count compared to the 8c/16t setup on the Ryzen 7 5800X not to mention the whopping 16c/32T count on the Ryzen 9 5950X. Nonetheless, at 75% and 37.5% fewer cores, the Intel Core still manages to put up impressive results considering the gap in core count. The Core i5 11600K’s value lies in gaming, taking a look at our benchmark results we can clearly see a much tighter performance gap against the 8-core Ryzen 7 5800X, especially in 1080p resolution. There are even some instances where the superior single-thread performance and high boost clocks of the 11600K manage to surpass both the Ryzen 7 5800X and Intel’s very own 11900K. The Intel Core i5 11600K, like its predecessor, holds a very competitive price-to-performance ratio making it a solid choice for gaming. Its overclocking capability allows you to squeeze more performance especially if you have a good cooler paired with the 11600K. That said, the Intel Core i5 11600K is great for users who prioritize gaming and getting every bit of framerates over everything else.
