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

Head-to-Head Benchmarks

The AMD Ryzen 7 8840HX and Intel Core i9-14901KE are fundamentally different processors, and the recorded benchmark data reflects that divide clearly. The AMD part has a full suite of 13 benchmark scores across Cinebench and Passmark tests, while the Intel part has no recorded benchmark scores in the database. This means the head-to-head comparison is one-sided by necessity: every measurable performance indicator belongs to the AMD Ryzen 7 8840HX.

Starting with compute-heavy workloads, the Ryzen 7 8840HX delivers a Cinebench R23 multi-core score of 25265. In single-core performance, it reaches 1857 points in the same test suite. The Passmark suite further details its capabilities: integer math scores 146506, floating point math scores 86747, and extended instructions score 36527. Data compression work scores 496427, while data encryption reaches 29919. Prime number finding yields 304, random string sorting produces 57971, and the physics test records 2185. The multithread score is 41732, and the single-thread score is 3958.

Since the Intel Core i9-14901KE has zero recorded benchmarks, no direct score comparisons can be made. The database shows the AMD part at the 94th percentile among all CPUs, with an average benchmark score of 71797. The nearest rivals for the AMD chip are Intel Core Ultra 7 265KF with an average score of 71910 and a delta of -0.2%, Intel Xeon Platinum 8270 at 71370 with a delta of +0.6%, Intel Xeon 6517P at 72350 with a delta of -0.8%, and Intel Xeon 6724P at 72396 with a delta of -0.8%. These deltas indicate the Ryzen 7 8840HX sits within 1% of all four nearest rivals, effectively tied with each in average benchmark score.

The Intel Core i9-14901KE, by contrast, holds the 50th percentile among all CPUs with an average benchmark score of 0, and it has no nearest rivals listed. The contrast is stark: the AMD processor is a measured, verified performer, while the Intel processor lacks any recorded performance data in the database.

Where Each One Wins

The AMD Ryzen 7 8840HX wins every benchmark category where data exists. Its Cinebench R23 multi-core score of 25265 indicates strong parallel throughput, driven by its 12 cores and 24 threads. The single-core score of 1857 shows competitive per-thread performance for a mobile processor. In Passmark tests, the data reveals specific strengths: integer math at 146506 and floating point math at 86747 both indicate robust arithmetic processing, while extended instructions at 36527 shows solid SIMD workload handling. The data compression score of 496427 is particularly high relative to other tests, suggesting strong memory and cache efficiency in that workload. Random string sorting at 57971 also points to capable memory subsystem performance.

The Intel Core i9-14901KE has no benchmark data, so no wins can be assigned to it. The database records zero wins for the Intel part and zero wins for the AMD part in the head-to-head array, simply because no paired benchmark results exist. The practical implication is that the Ryzen 7 8840HX is the only processor in this comparison with verified performance, and its results place it in the 94th percentile of all CPUs. The Intel chip sits at the 50th percentile with no scores, making it unquantifiable in direct comparison.

For workload-specific analysis, the AMD chip shows a balanced profile. Its multithread score of 41732 and physics score of 2185 are moderate, while its single-thread score of 3958 indicates decent responsiveness in lightly threaded tasks. The encryption score of 29919 and prime number score of 304 are lower in absolute terms, but these are typical for such specialized operations. The overall picture is a processor that performs strongly across a wide range of compute tasks, with particular excellence in data compression and integer math.

The Verdict

Based strictly on the recorded data, the AMD Ryzen 7 8840HX is the only processor in this comparison with measurable performance. It delivers a Cinebench R23 multi-core score of 25265, a single-core score of 1857, and a Passmark average benchmark score of 71797, placing it at the 94th percentile of all CPUs. Its nearest rivals, all Intel Xeon or Core Ultra parts, sit within 0.8% of its average score, confirming that the AMD chip competes at a high level against server and high-end desktop processors.

The Intel Core i9-14901KE has no benchmark scores, no average score, and no nearest rivals in the database. Its 50th percentile ranking with an average score of 0 means it cannot be evaluated for performance from the available data. Anyone choosing between these two processors based on the database would have to select the AMD Ryzen 7 8840HX, because it is the only part with evidence of capability. The Intel chip may have merits in its specifications, but without benchmark results, no performance claims can be substantiated. The data shows one clear conclusion: the AMD Ryzen 7 8840HX is the measured performer, and the Intel Core i9-14901KE is an unverified alternative.
