Where Each One Wins

The benchmark data splits the two processors into distinct use-case profiles. The AMD Ryzen 9 9955HX3D wins 13 of the 15 head-to-head tests, and its victories are concentrated in heavily threaded and compute-intensive workloads. The Cinebench R15 multi-core result shows a 132.9% lead over the Intel part, with the AMD chip scoring 6042.5 versus 2595. Cinebench R23 multi-core follows a similar pattern, with the AMD chip at 38161.5 against 25753, a 48.2% advantage. These results indicate that rendering, video encoding, and other parallel workloads will favor the AMD processor by a wide margin.

PassMark integer math and floating-point math tests reinforce the same conclusion. The AMD Ryzen 9 9955HX3D scores 222503 in integer math, 97.4% higher than the Intel Core i9-14901E’s 112736. Floating-point math shows a 77.7% gap, with scores of 144122 and 81089 respectively. Data compression and encryption workloads also lean heavily toward AMD. The compression test shows a 172.1% difference, with scores of 785811 and 288777, while encryption shows 39446 versus 18571, a 112.4% advantage. Extended instruction workloads show the largest gap of any test, with the AMD part scoring 62813 against 17249, a 264.2% difference. Prime number finding and random string sorting also favor AMD by 177.8% and 113.3% respectively.

The Intel Core i9-14901E takes only two wins, both in single-core Cinebench tests. In Cinebench R15 single-core, Intel scores 366 against AMD’s 332, a 9.3% lead. Cinebench R23 single-core shows a larger gap: Intel’s 3635 beats AMD’s 2159.5 by 40.6%. These results suggest that lightly threaded applications that depend on a single thread, such as certain legacy software or some user interface responsiveness tasks, will run faster on the Intel part. The AMD chip still wins PassMark single-thread, scoring 4511 versus 4354, a 3.6% margin, so Intel’s single-core advantage does not extend across every benchmark suite.
