AMD Ryzen 7 8840HX vs Intel Core i5-14490F Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall advantage for the AMD Ryzen 7 8840HX, which wins 12 of the 13 shared benchmark comparisons. The single exception is a substantial Intel victory in Cinebench R23 single-core, where the Intel Core i5-14490F scores 3247 against 1857 for the AMD part, a 42.8% advantage. That result is the largest gap in either direction across the entire benchmark set.

The AMD Ryzen 7 8840HX leads most heavily in compute-heavy PassMark workloads. The largest margin appears in PassMark find prime numbers, where AMD scores 304 versus 122, a 149.2% advantage. PassMark extended instructions shows a 68.1% lead (36527 vs 21731), and PassMark integer math delivers a 66.8% edge (146506 vs 87844). PassMark data encryption follows at 64.2% (29919 vs 18225), while PassMark random string sorting shows a 62.8% gap (57971 vs 35608).

The multi-threaded picture reinforces the AMD lead. Cinebench R23 multi-core records 25265 for the AMD processor against 23000 for the Intel part, a 9.8% margin. PassMark multithread shows a much larger 45.6% gap (41732 vs 28662), and PassMark data compression lands at 46.0% (496427 vs 340026). PassMark floating point math adds a 30.3% advantage (86747 vs 66558). The smallest wins for AMD appear in PassMark physics (2185 vs 2093, a 4.4% gap) and PassMark single thread (3958 vs 3873, a 2.2% margin).

The aggregate benchmark averages reflect this split. The AMD Ryzen 7 8840HX posts an average benchmark score of 71797 and sits in the 94th percentile of all CPUs. Its nearest rival in the database, the Intel Core Ultra 7 265KF, scores 71910, a difference of only 0.2%. The Intel Core i5-14490F averages 38149, placing it in the 86th percentile, with its closest rival, the Intel Core Ultra 5 245T, at 38194, a 0.1% difference. The 8840HX therefore outperforms the 14490F by roughly 88% in average benchmark score, and the two processors occupy very different performance tiers relative to their nearest competitors.

Architecture Differences

The AMD Ryzen 7 8840HX uses AMD's Zen 4 architecture under the Dragon Range codename, built on a 5 nm process at TSMC. It integrates 13,140 million transistors across a 2x 71 mm² die configuration. The Intel Core i5-14490F uses the Raptor Lake architecture under the Raptor Lake-R codename, manufactured on Intel's 10 nm process with a 215 mm² die size. The foundry difference is notable: TSMC for AMD, Intel for the i5-14490F.

Core and thread counts differ substantially. The AMD part provides 12 cores and 24 threads, while the Intel part provides 10 cores and 16 threads. Cache hierarchies also diverge. The 8840HX offers 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The i5-14490F offers 80 KB of L1 per core, 1.25 MB of L2 per core, and only 24 MB of shared L3 cache. The AMD chip's 64 MB L3 is 2.7 times the Intel chip's 24 MB, which helps explain its strong showing in data-heavy PassMark workloads.

Clock behavior differs as well. The AMD Ryzen 7 8840HX has a base clock of 2.90 GHz and a boost clock of 5.10 GHz. The Intel Core i5-14490F has a lower base clock of 2.50 GHz and a boost clock of 5.00 GHz. The AMD part also carries an unlocked multiplier, whereas the Intel part is locked. Power envelopes favor the AMD design at 55 W TDP versus 65 W TDP for Intel, despite the AMD chip's higher core count and larger L3 cache.

Memory support shows a clear split. The AMD processor supports DDR5 only, with dual-channel access and a recorded memory bandwidth of 83.2 GB/s. The Intel processor supports both DDR4 and DDR5, also in dual-channel mode, but the database lists no specific memory bandwidth figure for it. Neither processor supports ECC memory.

PCIe connectivity differs. The AMD Ryzen 7 8840HX provides Gen 5 with 28 lanes (CPU only), while the Intel Core i5-14490F provides Gen 5 with 16 lanes (CPU only). The AMD part includes integrated graphics in the form of a Radeon 610M, while the Intel part has no integrated graphics (listed as N/A). This is a meaningful differentiator for systems that need a display output without a discrete GPU.

Market positioning also separates the two. The AMD Ryzen 7 8840HX is a mobile processor on AMD Socket FL1, released in April 2025. The Intel Core i5-14490F is a desktop processor on Intel Socket 1700, released in December 2023. Both remain in active production. The AMD part number is 100-000001850, and the Intel part number is SRN35.

The Verdict

The benchmark data supports a clear performance hierarchy. The AMD Ryzen 7 8840HX dominates in multi-threaded and compute-intensive workloads, with double-digit percentage leads in 10 of the 13 shared tests. Its 149.2% lead in PassMark find prime numbers and 68.1% lead in extended instructions indicate a strong advantage in integer and SIMD-style workloads. The 64 MB L3 cache and 12-core, 24-thread configuration are consistent with this pattern.

The Intel Core i5-14490F holds a single but significant advantage in Cinebench R23 single-core, where its 3247 score is 42.8% higher than the AMD part's 1857. This suggests that workloads relying heavily on single-thread performance would favor the Intel chip. However, the PassMark single-thread test tells a different story: the AMD part leads there by 2.2% (3958 vs 3873). The Cinebench single-core gap is therefore workload-specific rather than a universal single-thread advantage.

Given the average benchmark scores, the AMD Ryzen 7 8840HX belongs to a performance class far above the Intel Core i5-14490F. The 8840HX sits at 71797 average, near the Intel Core Ultra 7 265KF, while the i5-14490F sits at 38149, near the Intel Core i5-13600KF. The 88% difference in average score, combined with higher core counts, more L3 cache, a smaller process node, lower TDP, and unlocked multiplier, makes the AMD part the stronger overall processor in the recorded data.

The Intel part's relevance comes from its single-core Cinebench result and its dual-channel support for both DDR4 and DDR5. For desktop builds where the motherboard ecosystem and memory flexibility matter, and where single-thread Cinebench performance is prioritized, the i5-14490F remains viable. But the aggregate benchmark evidence positions the AMD Ryzen 7 8840HX as the higher-performing chip across the majority of tested workloads.
