This in-depth comparison will help you understand the key differences between the Intel Core i9 11900KB vs Intel Core i9 13900HX and decide which CPU is the best fit for your specific needs.

Architecture and Core Count: A Generation Apart

The Intel Core i9 11900KB is based on the Rocket Lake architecture, while the Intel Core i9 13900HX is powered by the Raptor Lake architecture. This generational leap brings significant advancements to the 13900HX, including a larger core count and improved performance.
The 11900KB boasts 8 cores and 16 threads, while the 13900HX offers a whopping 24 cores (8 performance cores and 16 efficient cores) and 32 threads. This translates to more processing power for the 13900HX, allowing it to handle demanding tasks like video editing, 3D rendering, and multitasking with ease.

Clock Speeds and Turbo Boost: A Race to the Top

Both CPUs offer impressive clock speeds, but the 13900HX takes the lead. The 11900KB has a base clock speed of 3.3 GHz and a boost clock speed of 5.3 GHz. On the other hand, the 13900HX boasts a base clock speed of 2.3 GHz but can reach a turbo boost clock speed of 5.4 GHz. This difference in clock speeds, coupled with the higher core count, gives the 13900HX a substantial performance advantage.

Cache Memory: A Crucial Difference

Cache memory plays a vital role in CPU performance, acting as a temporary storage space for frequently used data. The 11900KB has 20 MB of L3 cache, while the 13900HX boasts a larger 36 MB of L3 cache. This larger cache allows the 13900HX to access data more quickly, leading to faster processing speeds.

Integrated Graphics: A Necessary Feature

Both CPUs feature integrated graphics, which can be useful for basic tasks like web browsing and video playback. The 11900KB utilizes Intel Iris Xe Graphics, while the 13900HX features Intel Iris Xe Graphics. However, for demanding gaming or graphic-intensive tasks, dedicated graphics cards are recommended.

Power Consumption: A Trade-off for Performance

The 13900HX’s increased performance comes at the cost of higher power consumption. It has a TDP (Thermal Design Power) of 55W, while the 11900KB has a TDP of 45W. This means the 13900HX will require more power and potentially generate more heat, impacting battery life in laptops.

Benchmark Performance: A Clear Winner

Benchmark results consistently show the Intel Core i9 13900HX outperforming the Intel Core i9 11900KB in various tasks. In single-core benchmarks, the 13900HX’s performance cores deliver significant gains, while in multi-core benchmarks, the additional cores and threads of the 13900HX lead to a substantial performance advantage.

Choosing the Right CPU: Your Needs Matter Most

So, which CPU is right for you? The answer depends on your individual needs and priorities.
The Intel Core i9 11900KB is a good choice for:

• Users who prioritize affordability
• Users who need a powerful CPU for everyday tasks like browsing, productivity, and light gaming
