AMD Ryzen 9 8945HX vs Intel Core i9-14901KE Comparison

Head-to-Head Benchmarks

The benchmark data provides a complete picture for the AMD Ryzen 9 8945HX, while the Intel Core i9-14901KE has no recorded measurements in the database. This means all comparative analysis must rely on the AMD processor's absolute scores and its position against the nearest rivals listed in the database, rather than direct head-to-head results between the two processors.

The AMD Ryzen 9 8945HX delivers a multi-core Cinebench R23 score of 42713, a result that places it at the 95th percentile among all CPUs in the database. Its single-core score in the same test reaches 6030. In Cinebench R20, the chip records 17939 multi-core and 2532 single-core. The older Cinebench R15 test shows 4305 multi-core and 607 single-core. These results confirm the processor sustains high throughput across rendering workloads.

PassMark results add further detail. The Ryzen 9 8945HX scores 195180 in integer math, 117453 in floating point math, and 51405 in multithread. Single-thread PassMark reaches 3907. Data compression scores 677755, while data encryption hits 40836. Extended instructions score 49823. Random string sorting achieves 78781, and find prime numbers scores 262. Physics tests deliver 2168.

The average benchmark score for the AMD chip is 76212. When compared to its nearest rivals in the database, the Ryzen 9 8945HX sits within a tight cluster. The Intel Core Ultra 9 285HX averages 76155, a delta of 0.1 percent in favor of the AMD part. The AMD EPYC Embedded 8224P averages 76492, placing the Ryzen 9 8945HX 0.4 percent behind. The AMD Ryzen Threadripper PRO 9945WX averages 76513, also 0.4 percent ahead. The AMD Ryzen 9 9950X3D averages 75779, putting the 8945HX 0.6 percent ahead. These deltas show the Ryzen 9 8945HX performs essentially at parity with its closest competitors, with all differences within one percentage point.

Because the Intel Core i9-14901KE has no benchmark scores recorded, the database cannot calculate any wins for either processor in head-to-head comparisons. The AMD part therefore stands as the only measured entity in this comparison, and its data indicates strong multi-threaded capability relative to the broader CPU landscape.

Where Each One Wins

The AMD Ryzen 9 8945HX wins in every measurable category because the database contains no benchmark results for the Intel Core i9-14901KE. The recorded data shows the AMD processor delivers its strongest performance in multi-core workloads. The Cinebench R23 multi-core score of 42713, combined with the PassMark multithread score of 51405, indicates the chip excels in rendering, compilation, and heavily threaded productivity tasks.

Single-core performance is also solid, with a Cinebench R23 single-core score of 6030 and a PassMark single-thread score of 3907. These numbers suggest the processor handles lightly threaded applications such as web browsing, office productivity, and legacy software without bottlenecking. The PassMark integer math score of 195180 and floating point math score of 117453 point to strong general-purpose computational throughput.

The data compression score of 677755 and random string sorting score of 78781 indicate the AMD processor handles data manipulation tasks efficiently. Encryption workloads also benefit, with a score of 40836. The extended instructions score of 49823 shows the processor supports modern instruction sets with good execution rates.

For the Intel Core i9-14901KE, the database lists no wins because no measurements exist. The processor's architecture and specifications are recorded, but its performance characteristics cannot be assessed from the available data. Any assertion about where the Intel part wins would require benchmark results that are absent from the database.

The Verdict

The data supports a clear distinction between these two processors, though the absence of Intel benchmark results limits direct comparison. The AMD Ryzen 9 8945HX has extensive recorded measurements showing strong multi-core and single-core performance. Its Cinebench R23 multi-core score of 42713 and 95th percentile ranking among all CPUs indicate it handles demanding workloads effectively. The average benchmark score of 76212 places it within one percentage point of several high-end rivals, including the Intel Core Ultra 9 285HX, AMD EPYC Embedded 8224P, AMD Ryzen Threadripper PRO 9945WX, and AMD Ryzen 9 9950X3D.

The Intel Core i9-14901KE offers a higher boost clock at 5.80 GHz and a higher base clock at 3.80 GHz, along with support for both DDR4 and DDR5 memory and ECC memory. Its 8 cores and 16 threads are fewer than the AMD part's 16 cores and 32 threads. The Intel processor targets the desktop segment with a 125 W TDP, while the AMD processor targets mobile with a 55 W TDP.

Given the recorded data, the AMD Ryzen 9 8945HX is the processor with measurable performance, and its multi-core scores indicate it excels in threaded workloads. The Intel Core i9-14901KE cannot be evaluated from the database, so any selection between the two must rely on the AMD part's verified results. The AMD processor's higher core count, larger L3 cache, and lower TDP make it the only option with demonstrated benchmark performance in this comparison.
