By the end of this article, you’ll have a clear understanding of which CPU is the right fit for your specific needs and budget.
Architecture and Performance
The Intel Core i5-1240U is part of Intel’s 12th generation Alder Lake series, featuring a hybrid architecture with both performance (P-cores) and efficiency (E-cores). This architecture allows for efficient power consumption while maintaining high performance for demanding tasks. On the other hand, the Intel Core i9-11900KB is a member of Intel’s 11th generation Rocket Lake series, featuring a traditional architecture with only performance cores.
In terms of performance, the i9-11900KB significantly outperforms the i5-1240U in raw processing power, thanks to its higher core count and clock speeds. The i9-11900KB boasts 8 cores and 16 threads, while the i5-1240U has 10 cores (2 P-cores + 8 E-cores) and 12 threads. However, the i5-1240U’s hybrid architecture allows it to manage power consumption more efficiently, making it ideal for mobile devices.
Benchmark Comparisons
To understand the performance differences between these CPUs, let’s look at some benchmark comparisons:
- Cinebench R23: The i9-11900KB scores significantly higher in multi-core performance, thanks to its higher core count and clock speeds.
- Geekbench 5: The i9-11900KB again demonstrates superior performance in both single-core and multi-core benchmarks.
- 3DMark Time Spy: The i9-11900KB delivers better gaming performance, especially in demanding titles.
While the i9-11900KB excels in benchmark scores, it’s important to remember that the i5-1240U is designed for a different purpose. Its focus on power efficiency makes it a better choice for laptops and other mobile devices, where performance is still important but power consumption needs to be minimized.
