AMD Ryzen 9 9900X vs Intel Core i9-14900HX Comparison

The comparison between the Intel Core i9-14900HX and the AMD Ryzen 9 9900X is a study in contrasts: a mobile processor with 24 cores facing a desktop processor with 12 cores. The benchmark data delivers a decisive outcome, with AMD’s Ryzen 9 9900X winning every single head-to-head test, a total of 17 wins against zero for Intel. The average benchmark scores reinforce this gap, with the Ryzen 9 9900X posting an average of 57,498 compared to the Core i9-14900HX’s 56,004. This puts the Intel part in the 91st percentile of all CPUs, while the AMD chip sits one percentile higher at 92, a narrow margin that belies the consistency of the AMD victories.

Head-to-Head Benchmarks

The most dramatic divergence appears in single-core and extended instruction workloads. In Geekbench single-core, the Ryzen 9 9900X scores 3,010 against Intel’s 2,330, a 22.6% advantage that signals a substantial architectural efficiency lead. The same pattern holds in Cinebench R15 single-core, where AMD wins by 12% (353 vs. 310.5). Even in Cinebench R23 single-core, a test where Intel’s boost clock of 5.80 GHz should help, the Ryzen 9 9900X still leads by 3.2% with a score of 2,253 versus 2,181.5. This suggests that raw clock speed alone cannot compensate for the IPC gains of AMD’s newer design.

Multi-core results tell a similar story, though the margins vary by workload. In Geekbench multi-core, the Ryzen 9 9900X achieves 22,174, a 21% lead over the Core i9-14900HX’s 17,511. Cinebench R23 multi-core shows a narrower gap, with AMD winning 32,172 to 30,055, a 6.6% difference. The PassMark multi-thread test reveals a 19.9% advantage for AMD (54,643 vs. 43,778). Interestingly, the Cinebench R15 multi-core test shows AMD ahead by 8.7% (5,008 vs. 4,574), despite Intel having 24 cores and 32 threads against AMD’s 12 cores and 24 threads. This points to the Ryzen 9 9900X’s superior per-core throughput in heavily threaded rendering tasks.

The largest single delta appears in the PassMark extended instructions test, where AMD wins by 43.4% (55,243 vs. 31,247). This is a massive gap that likely reflects the Zen 5 architecture’s improved AVX-512 and SIMD handling. The prime number calculation test is even more lopsided, with AMD scoring 436 versus Intel’s 193, a 55.7% difference that highlights raw integer execution efficiency. Data compression shows AMD ahead by 21% (683,579 vs. 539,965), while random string sorting sees a 15.5% advantage (72,013 vs. 60,861). Even in the closest contest, data encryption, AMD still wins by 2.4% (33,421 vs. 32,619), proving that Intel’s mobile processor cannot find a single workload where it outpaces the desktop part.

Architecture Differences

The architectural chasm between these two chips explains the benchmark results. Intel’s Core i9-14900HX uses the Raptor Lake architecture on a 10 nm process, built by Intel itself. AMD’s Ryzen 9 9900X employs Zen 5 architecture on a 4 nm process from TSMC, which allows for dramatically higher transistor density. The transistor counts reflect this: AMD’s chip packs 16,630 million transistors across two 70.6 mm² dies, while Intel’s die size is 257 mm² with no transistor count listed. The smaller process node gives AMD a clear efficiency and IPC advantage, which shows up in the single-core tests.

Cache configurations differ significantly. Both chips have 80 KB of L1 cache per core, but Intel offers 2 MB of L2 per core while AMD provides only 1 MB per core. The L3 cache tells the opposite story: AMD has 64 MB shared, versus Intel’s 36 MB shared. This larger L3 cache likely contributes to AMD’s wins in data compression and random string sorting, where frequent data access patterns benefit from more on-die storage. Memory support also diverges, with Intel supporting both DDR4 and DDR5, while AMD is DDR5-only. AMD’s memory bandwidth is listed at 89.6 GB/s, a figure Intel does not provide, which could explain some of the multi-core throughput advantages.

The core counts are starkly different: Intel fields 24 cores and 32 threads, while AMD has 12 cores and 24 threads. Despite having half the cores, AMD wins every multi-threaded test, which indicates that Zen 5’s per-core performance is so high that it overcomes the numerical disadvantage. Clock speeds favor Intel slightly, with a 5.80 GHz boost versus AMD’s 5.60 GHz, but base clocks are far apart: Intel at 2.20 GHz versus AMD at 4.40 GHz. The TDP also differs enormously, with Intel rated at 55 watts and AMD at 120 watts, though this reflects their different market segments—mobile versus desktop.

The Verdict

The data is unambiguous: the AMD Ryzen 9 9900X is the superior processor in every measured benchmark. With 17 wins out of 17 head-to-head tests, there is no workload category in this dataset where the Intel Core i9-14900HX comes out ahead. The average benchmark score difference (57,498 vs. 56,004) is modest, but the per-test deltas are consistently in AMD’s favor, ranging from 2.4% in data encryption to 55.7% in prime number calculations. The Ryzen 9 9900X also holds a higher percentile ranking at 92 versus 91, though this is a narrow margin that suggests both are near the top of the CPU hierarchy.

For users prioritizing single-thread performance, the Ryzen 9 9900X is the clear choice, as shown by the 22.6% lead in Geekbench single-core. For multi-threaded rendering, the Cinebench R23 multi-core score favors AMD by 6.6%, which is a meaningful advantage for content creators. The extended instructions test, which is critical for scientific computing and encryption workloads, shows a 43.4% advantage for AMD, making it the better pick for those specialized tasks. The only caveat is the Intel part’s mobile form factor, which allows it to fit into laptops, but the data does not show any performance benefit from that portability.

Where Each One Wins

Based strictly on the benchmark data, the AMD Ryzen 9 9900X wins in every category, but the magnitude of the wins varies by workload type. For general productivity and everyday tasks, the Geekbench single-core score of 3,010 versus 2,330 gives AMD a commanding lead that translates to snappier application responsiveness. In rendering and 3D workloads, the Cinebench R23 multi-core score of 32,172 versus 30,055 shows AMD’s advantage, though it is narrower than other tests. The PassMark physics test, which simulates game physics, favors AMD by 22% (3,381 vs. 2,638), suggesting better gaming performance despite the lack of a discrete GPU comparison.

For data-heavy tasks, the AMD chip wins decisively. Data compression shows a 21% lead (683,579 vs. 539,965), and random string sorting is 15.5% faster (72,013 vs. 60,861). The extended instructions test, which measures SIMD and vector processing, is a 43.4% blowout in AMD’s favor (55,243 vs. 31,247), making it the obvious choice for scientific or financial workloads. Even in floating-point math, where Intel’s 24 cores might be expected to help, AMD wins by 6.5% (120,083 vs. 112,273). The only area where Intel comes close is data encryption, with a 2.4% deficit, but that still leaves AMD ahead. There is no workload in the dataset where the Intel Core i9-14900HX can claim victory, so the use-case split is entirely in AMD’s favor for those who can use a desktop processor.
