AMD Ryzen 7 PRO 8840U vs Intel Core i9-14901KE Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark record for the AMD Ryzen 7 PRO 8840U, but the Intel Core i9-14901KE has no recorded benchmark scores. This creates an asymmetric comparison. The AMD part's scores can be examined in absolute terms and against its nearest rivals, while the Intel part's performance must be inferred from its architectural specifications and market positioning.

The Ryzen 7 PRO 8840U delivers a Cinebench R23 multi-core score of 20,254 and a single-core score of 2,859. In Cinebench R20, it records 8,506 multi-core and 1,200 single-core. The R15 results show 2,041 multi-core and 288 single-core. These scores place the chip at the 83rd percentile among all CPUs in the database.

PassMark results for the AMD part show a multi-thread score of 23,850 and a single-thread score of 3,641. The data compression test returns 272,664, while data encryption hits 16,441. Extended instructions score 19,132, floating point math reaches 50,746, and integer math sits at 88,339. Physics workloads produce 1,174, and random string sorting yields 33,109. Prime number finding is a modest 76.

The nearest rivals for the Ryzen 7 PRO 8840U include the Intel Core i9-11900 with an average score of 32,226 and a delta of 0%, the Intel Core i5-14400F at 32,279 with a delta of -0.1%, the Intel Core i7-12800H at 32,121 with a delta of 0.3%, and the Intel Core i5-14400 at 32,115 with a delta of 0.4%. The average benchmark score for the AMD part is 32,233. These deltas are all within a fraction of a percent, indicating the Ryzen 7 PRO 8840U performs essentially on par with these four Intel parts in aggregate.

The Intel Core i9-14901KE has an average benchmark score of 0 and sits at the 50th percentile, with no nearest rivals listed. The data shows no head-to-head benchmark entries and zero wins for either part. This means the comparison must rely on architecture, cache, memory, and feature differences rather than measured performance outcomes.

Architecture Differences

The Ryzen 7 PRO 8840U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. The transistor count is 25,000 million on a die size of 178 mm². The Intel Core i9-14901KE uses Raptor Lake architecture under the Raptor Lake-R codename, built on a 10 nm process at Intel. Its die size is 257 mm², and no transistor count is recorded.

Both parts have 8 cores and 16 threads. The AMD chip has a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The Intel chip runs a base clock of 3.80 GHz and a boost clock of 5.80 GHz. The Intel part holds the clock advantage, with 0.50 GHz higher base and 0.70 GHz higher boost.

Cache hierarchies differ substantially. The AMD part uses 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel part uses 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Intel chip has more L1, double the L2 per core, and more than double the L3 capacity. This larger cache footprint typically benefits workloads with repeated data access.

Memory support differs. The AMD chip supports DDR5 only, with dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Intel chip supports both DDR4 and DDR5, dual-channel, but no memory bandwidth figure is recorded. Both parts support ECC memory.

PCIe capabilities differ. The AMD part uses Gen 4 with 20 lanes from the CPU. The Intel part uses Gen 5 with 16 lanes from the CPU. The Intel chip offers a newer PCIe generation, while the AMD chip provides more lanes.

Integrated graphics differ. The AMD part uses Radeon 780M, while the Intel part uses UHD Graphics 770. Both are integrated solutions, but their performance characteristics are not benchmarked in this database.

Process node and foundry differences are stark. The AMD chip is on TSMC's 4 nm process, while the Intel chip is on Intel's 10 nm process. The smaller process node for AMD typically implies better power efficiency per transistor, though the Intel part's higher TDP suggests a different power envelope.

Where Each One Wins

The recorded data shows the Ryzen 7 PRO 8840U winning in every benchmark category where scores exist, simply because the Intel Core i9-14901KE has no recorded scores. The AMD part's 83rd percentile ranking and average score of 32,233 indicate it competes well with mid-range and upper-mid-range desktop and mobile processors.

For the AMD chip, the strongest results appear in data compression (272,664) and integer math (88,339). These suggest workloads involving file compression, database operations, and general integer-heavy computation would see solid throughput. The floating point math score of 50,746 and multi-thread score of 23,850 indicate good parallel processing capability.

The single-core scores tell a different story. The Cinebench R23 single-core score of 2,859 and PassMark single-thread score of 3,641 place the AMD chip in a competitive range, but the Intel part's higher boost clock of 5.80 GHz compared to 5.10 GHz suggests the Intel chip likely has an advantage in single-threaded workloads, though this is not confirmed by recorded benchmarks.

The Intel part's architecture features, such as 36 MB of L3 cache and support for DDR5, point toward strengths in gaming and latency-sensitive applications. The AMD part's smaller process node and lower TDP of 28 W versus 125 W indicate a power efficiency advantage. The AMD chip is also a mobile part, while the Intel chip is a desktop part, suggesting different intended use cases.

The AMD chip's PCIe Gen 4 with 20 lanes offers more total lanes, which could benefit systems with multiple NVMe drives or expansion cards. The Intel chip's PCIe Gen 5 with 16 lanes offers higher bandwidth per lane, which could benefit a single high-speed GPU or storage device.

The Verdict

The data presents an unusual situation. The AMD Ryzen 7 PRO 8840U has a full set of benchmark results, while the Intel Core i9-14901KE has none. The recorded measurements show the AMD part performing at the 83rd percentile with an average score of 32,233, placing it alongside the Intel Core i9-11900, Core i5-14400F, Core i7-12800H, and Core i5-14400 within a 0.4% delta.

For users selecting between these two specific parts, the AMD chip has demonstrated performance in the database, while the Intel chip has no measured results to compare. The Intel part's specifications indicate higher clocks, more cache, and a newer PCIe generation, but these are not confirmed by benchmark data. The AMD part's 28 W TDP versus 125 W for Intel suggests the mobile-class AMD chip is designed for power efficiency, while the desktop-class Intel chip targets raw performance within a higher power budget.

The database shows the AMD chip as an active, mobile-market processor with a 4 nm process and 89.6 GB/s memory bandwidth. The Intel chip is an active, desktop-market processor with a 10 nm process and no recorded bandwidth. Both support ECC memory and dual-channel memory buses.

The Intel part is multiplier unlocked, indicating overclocking capability, while the AMD part is locked. The Intel part's socket 1700 and PCIe Gen 5 support point to a modern desktop platform, while the AMD part's FP7 socket and PCIe Gen 4 target thin-and-light or mainstream mobile systems.

Based on recorded data, the AMD Ryzen 7 PRO 8840U is the only part with proven benchmark performance. The Intel Core i9-14901KE offers higher clock speeds and a larger cache per its specifications, but the database contains no measurements to validate its real-world standing. Users prioritizing verified results would choose the AMD part, while those prioritizing higher specified clocks and cache capacity might consider the Intel part, though its performance remains unmeasured.
