Intel Core i9-14900HX

The Intel Core i9-14900HX is a 24-core, 32-thread mobile processor from the Core 14th Gen series, built on the Raptor Lake-HX architecture. It boosts to 5.80 GHz from a 2.20 GHz base, carries a 55 W TDP, and ranks at the 95th percentile of all CPUs with an average benchmark score of 58397. Benchmark results indicate a chip that excels in both single-thread responsiveness and multi-thread throughput, holding its own against server and desktop parts while remaining a mobile-first design.

Single-Thread vs Multi-Thread Behavior

The 14900HX pairs a 2.20 GHz base clock with a 5.80 GHz boost, which directly drives its single-thread results. In Cinebench R23, the single-core score is 5440, while the multi-core score reaches 38536 – a ratio of roughly 7.1x. This scaling shows that the 24 physical cores and 32 threads are effectively utilized when workloads expand. Geekbench echoes this: 2680 single-core versus 15658 multi-core, a 5.8x multiplier. Passmark's single-thread score of 4246 and multithread score of 45339 indicate an even larger 10.7x scaling, reflecting heavy parallelization in that benchmark. For real workloads, the high boost clock ensures snappy performance in lightly threaded tasks such as web browsing, office applications, and legacy software, while the 24 cores provide substantial headroom for rendering, video encoding, and code compilation. The data suggests the chip does not sacrifice single-thread speed to achieve multi-thread performance; it excels at both. Cinebench R15 results (548 single, 3884 multi) and R20 results (2284 single, 16185 multi) confirm this balanced profile across different test generations.

How It Compares

Against the AMD Ryzen AI Max PRO 390, the 14900HX holds a marginal 0.1% edge in average benchmark score (58397 vs 58362). This is a statistical tie, meaning the two chips are effectively interchangeable in overall performance. The Intel Xeon Platinum 8260M, a server-grade part, is also 0.1% behind (58323), showing that the mobile 14900HX can match a dual-socket-era Xeon in average throughput. The AMD EPYC 7313 trails by 1.7% (57399), a small but measurable gap that favors the 14900HX despite the EPYC's server heritage. The most notable rival is the Intel Core i7-14700, which leads the 14900HX by 2.1% (59621 vs 58397). This is interesting because the i7-14700 is a desktop part, and the data shows it outperforms the mobile HX chip by a small margin, likely due to higher sustained power limits on desktop platforms. The 14900HX's 95th percentile ranking places it among the top 5% of all CPUs, and these deltas confirm it sits in a competitive zone where no single rival dominates by more than a few percent.

Benchmark Performance

The benchmark suite reveals a chip optimized for both integer and floating-point workloads. In Passmark, the integer math score is 162363, while floating-point math reaches 115994 – a 40% advantage for integer operations, typical for a processor with a high clock speed and wide core count. Data compression scores 560104, and data encryption reaches 33805, indicating strong throughput for archival and security-related tasks. Extended instructions score 32457, showing robust SIMD performance. The find-prime-numbers test returns a modest 200, which is a specialized workload and not representative of general performance. Physics simulation scores 2761, and random string sorting hits 62804. In Cinebench, the R23 multi-core score of 38536 places it well ahead of the average mobile processor, and the single-core 5440 is equally strong. The average benchmark score of 58397 is the primary metric for comparison; relative to its nearest rivals, the deltas are tight – 0.1% ahead of the Ryzen AI Max PRO 390 and Xeon 8260M, 1.7% ahead of the EPYC 7313, and 2.1% behind the Core i7-14700. These numbers indicate the 14900HX delivers top-tier performance for a mobile chip, but it is not the absolute fastest CPU in the database; rather, it holds a competitive position against server and desktop parts that draw more power.
