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

# AMD Ryzen 7 PRO 8840U vs Intel Core i5-14490F

The database places these two processors in different market segments, yet their average benchmark scores tell a more nuanced story. The AMD Ryzen 7 PRO 8840U, a mobile part with 8 cores and 16 threads, averages 32,233 across all recorded tests. The Intel Core i5-14490F, a desktop chip with 10 cores and 16 threads, averages 38,149. That 15.5% gap in average score, however, masks a critical detail: the Ryzen chip wins one test outright, and the Intel chip's margins vary dramatically depending on workload. The recorded data shows a mobile processor that holds its own in integer math, while the desktop processor dominates everything else, often by double-digit margins.

Where Each One Wins

The AMD Ryzen 7 PRO 8840U claims exactly one head-to-head victory in the database: PassMark integer math, where it scores 88,339 against the Intel chip's 87,844, a 0.6% edge. That result is narrow, but it is the only test where the mobile part leads. The Intel Core i5-14490F wins the remaining 16 recorded benchmarks, with margins ranging from 6% to 43.9%. The largest Intel advantage comes in PassMark physics, where the desktop chip scores 2,093 against the Ryzen's 1,174, a 43.9% gap. Data compression also heavily favors Intel: 340,026 versus 272,664, a 19.8% lead. Floating point math goes to Intel by 23.8%, with scores of 66,558 and 50,746. Prime number finding shows the widest relative swing at 37.7%, with Intel at 122 and AMD at 76. The Intel chip also leads in every Cinebench test, all by 11.9% or 12%. For single-threaded PassMark, Intel is 6% ahead, and for multithreaded PassMark, Intel leads by 16.8%. The data indicates a clear split: the Ryzen part is competitive only in integer-heavy integer math, while the Intel part dominates rendering, physics, encryption, compression, and general multithreaded workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 8840U uses Zen 4 architecture on a 4nm TSMC process, with the Hawk Point codename. It packs 25,000 million transistors into a 178 mm² die. The Intel Core i5-14490F uses Raptor Lake architecture on Intel's 10nm process, with a 215 mm² die size. Intel does not report transistor counts in the database. The Ryzen chip has 8 cores and 16 threads, all based on the same Zen 4 design. The Intel chip has 10 cores and 16 threads, using a hybrid arrangement of performance and efficiency cores typical of Raptor Lake. Cache configurations differ substantially. The AMD part provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. That 8 MB L3 advantage helps Intel in workloads with large working sets. Clock speeds also differ. The AMD chip has a 3.30 GHz base and 5.10 GHz boost. The Intel chip has a 2.50 GHz base and 5.00 GHz boost. Despite the lower base clock, Intel's boost reaches within 0.1 GHz of AMD's, and its higher core count compensates in multithreaded tests. Power envelopes are starkly different: the Ryzen part is rated at 28W TDP, while the Intel part is rated at 65W TDP. That 37W difference explains why a mobile processor cannot match a desktop chip in sustained heavy workloads. The AMD chip uses AMD Socket FP7, supports DDR5 memory, and has 20 PCIe Gen 4 lanes. The Intel chip uses Intel Socket 1700, supports both DDR4 and DDR5, and offers 16 PCIe Gen 5 lanes. The AMD part includes integrated Radeon 780M graphics, while the Intel part has no integrated graphics. AMD supports ECC memory; Intel does not. The Ryzen chip is a mobile product released in April 2024; the Intel chip is a desktop product released in December 2023. Both are active production parts, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The Cinebench suite shows consistent Intel dominance. In Cinebench R15 multicore, Intel scores 2,318 versus AMD's 2,041, an 11.9% lead. Single-core R15 follows the same pattern: Intel at 327, AMD at 288, again 11.9% apart. R20 multicore gives Intel 9,660 and AMD 8,506, an 11.9% difference. R20 single-core shows Intel at 1,363 and AMD at 1,200, a 12% gap. R23 multicore records Intel at 23,000 and AMD at 20,254, 11.9% apart. R23 single-core has Intel at 3,247 and AMD at 2,859, 11.9% apart. The uniformity of these Cinebench deltas suggests a consistent per-core advantage for Intel in rendering workloads, regardless of thread count. PassMark results vary more widely. Data compression gives Intel a 19.8% lead, with scores of 340,026 and 272,664. Data encryption shows a narrower 9.8% gap: 18,225 versus 16,441. Extended instructions favor Intel by 12%, at 21,731 and 19,132. Prime number finding is the outlier: Intel scores 122, AMD scores 76, a 37.7% lead. Floating point math gives Intel 66,558 against 50,746, a 23.8% advantage. Integer math, as noted, is the sole AMD win at 88,339 versus 87,844, just 0.6% apart. Multithreaded PassMark shows Intel at 28,662 and AMD at 23,850, a 16.8% gap. Physics is the largest single delta: Intel 2,093, AMD 1,174, a 43.9% lead. Random string sorting gives Intel 35,608 versus 33,109, a 7% edge. Single-thread PassMark shows Intel at 3,873 and AMD at 3,641, 6% apart. The data indicates that Intel's advantage grows in tests that stress sustained throughput, such as physics and prime finding, while shrinking in single-threaded and integer tasks.

The average scores place each chip near distinct rivals. The Ryzen 7 PRO 8840U sits within 0.4% of the Intel Core i5-14400, within 0.3% of the Intel Core i7-12800H, and within 0.1% of the Intel Core i5-14400F. Its closest neighbor is the Intel Core i9-11900, with a delta of 0%. The Intel Core i5-14490F, by contrast, sits within 0.3% of the Intel Core i5-13600HX, within 0.2% of the AMD Ryzen 7 250, and within 0.1% of the Intel Core i5-13600KF. Its closest neighbor is the Intel Core Ultra 5 245T, with a delta of -0.1%. These nearest-rival comparisons confirm that the Ryzen chip performs like a high-end mobile part from previous generations, while the Intel chip aligns with mid-range desktop parts from the same era.

The Verdict

The database presents a clear performance hierarchy. The Intel Core i5-14490F wins 16 of 17 recorded benchmarks, and its average score of 38,149 places it in the 86th percentile of all CPUs. The AMD Ryzen 7 PRO 8840U wins one test, averages 32,233, and sits in the 83rd percentile. For workloads measured by Cinebench, PassMark compression, encryption, floating point, physics, prime finding, and multithreaded tasks, the Intel chip is the stronger choice by margins from 6% to 43.9%. The Ryzen chip's single victory in integer math is narrow and does not offset its deficits elsewhere. The Intel part also offers 10 cores versus 8, 24 MB of L3 versus 16 MB, and a 65W power envelope versus 28W. Those architectural advantages translate directly into the measured benchmark leads. The AMD part's strengths lie elsewhere: it includes integrated graphics, supports ECC memory, uses a smaller 4nm process, and draws less power. For users who need a processor with built-in graphics, ECC support, or lower power consumption, the Ryzen 7 PRO 8840U is the only option of the two. For users who prioritize raw compute performance in rendering, physics, compression, or encryption, the Intel Core i5-14490F is the superior part according to every recorded benchmark except integer math. The percentile rankings confirm this: the Intel chip outperforms 86% of all CPUs in the database, while the AMD chip outperforms 83%. The data does not indicate any scenario where the Ryzen chip matches or exceeds the Intel chip outside of integer math and the specific advantages of integrated graphics, ECC, and lower TDP.
