It is built on a 4 nm process at TSMC and packs 16,630 million transistors across a dual-die design with each die measuring 70.6 mm². The chip features 80 KB of L1 cache per core, 1 MB of L2 per core, and a substantial 128 MB of L3 cache, which is characteristic of the 3D V-Cache lineup. It uses AMD Socket FL1 and is classified as a mobile processor.

The Intel Core 9 273PE uses the Bartlett Lake codename and is built on a 10 nm process at Intel. It features 80 KB of L1 cache per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. This chip uses Intel Socket 1700 and is classified as a desktop processor. The Intel part supports both DDR4 and DDR5 memory, while the AMD chip supports DDR5 only. Both support ECC memory.

PCIe connectivity differs as well. The AMD processor provides Gen 5 with 28 lanes (CPU only), while the Intel processor provides Gen 5 with 16 lanes (CPU only). Integrated graphics also differ: the AMD chip uses Radeon 610M, and the Intel chip uses UHD Graphics 730. The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD processor was released on 2025-01-05, and the Intel processor was released on 2026-03-08. The Intel part has a launch MSRP of $549.

The Verdict

The benchmark data clearly separates these two processors into different roles. The AMD Ryzen 9 9955HX3D is the multi-threaded workhorse, winning 13 of the 15 head-to-head benchmarks. Its wins include massive margins in data compression (93.6%), data encryption (73.6%), extended instructions (155%), prime number finding (158.6%), and multithread performance (70.3%). The Intel Core 9 273PE wins only two benchmarks, both single-core Cinebench tests, but those wins are substantial, especially the 51.1% lead in Cinebench R23 single-core.

For users focused on heavily threaded workloads such as rendering, compression, encryption, or physics simulations, the AMD Ryzen 9 9955HX3D is the clear choice based on the recorded data. Its 16 cores, 32 threads, and 128 MB L3 cache deliver scores that place it at the 96th percentile. For users prioritizing single-thread performance, the Intel Core 9 273PE offers a significant edge in Cinebench R23 single-core, but that advantage does not translate to wins in the PassMark single-thread test, where the AMD chip leads by 23.6%.

The Intel part's overall average benchmark score of 49845 places it near rivals like the AMD Ryzen AI Max+ 388 (0.1% delta) and Intel Core i5-14600KF (0.9% delta). The AMD chip's average score of 97453 places it near the AMD Ryzen Threadripper PRO 5965WX (1.1% behind) and AMD Ryzen 9 PRO 9945 (1.4% ahead). The data suggests that the AMD processor competes in a higher performance tier entirely.

Head-to-Head Benchmarks

The AMD Ryzen 9 9955HX3D dominates the Cinebench R15 multicore test with a score of 6042.5 versus 3153 for the Intel Core 9 273PE, a 91.6% advantage. In Cinebench R23 multicore, the AMD chip scores 38161.5 versus 31288, a 22% lead. These results reflect the AMD part's higher core count and larger cache.

The Intel Core 9 273PE takes the single-core Cinebench tests. In Cinebench R15 single-core, it scores 445 versus 332, a 25.4% lead. In Cinebench R23 single-core, it scores 4417 versus 2159.5, a 51.1% lead. These are the only two benchmarks where the Intel part wins.

PassMark tests heavily favor the AMD processor. In data compression, the AMD chip scores 785811 versus 405885, a 93.6% lead. In data encryption, it scores 39446 versus 22719, a 73.6% lead. Extended instructions show a 155% lead (62813 versus 24630). Prime number finding shows a 158.6% lead (525 versus 203). Floating point math shows a 33.6% lead (144122 versus 107884). Integer math shows a 59.6% lead (222503 versus 139410). Multithread shows a 70.3% lead (62674 versus 36810). Physics shows a 50.2% lead (4687 versus 3120). Random string sorting shows an 85.1% lead (83497 versus 45098).

In the PassMark single-thread test, the AMD chip scores 4511 versus 3650, a 23.6% lead. This is notable because the Intel part wins the Cinebench single-core tests but loses the PassMark single-thread test.

Where Each One Wins

The AMD Ryzen 9 9955HX3D wins in every PassMark subtest and both Cinebench multicore tests. Its largest margins come in prime number finding (158.6%) and extended instructions (155%), followed by data compression (93.6%) and random string sorting (85.1%). These results point to workloads involving encryption, compression, scientific calculations, and sorting tasks. The 70.3% lead in PassMark multithread and 50.2% lead in physics further confirm its strength in heavily parallel workloads. The 23.6% lead in PassMark single-thread shows that even in lighter tasks, the AMD chip holds an edge in this specific benchmark.

The Intel Core 9 273PE wins only in Cinebench R15 single-core (25.4% lead) and Cinebench R23 single-core (51.1% lead). These wins indicate a strong per-core performance advantage in the Cinebench rendering engine's single-threaded mode. However, this advantage does not carry over to PassMark single-thread, where the AMD part leads by 23.6%. The Intel chip's higher boost clock of 5.70 GHz likely contributes to its Cinebench single-core wins, but the AMD chip's higher base clock and larger cache may explain its PassMark single-thread performance.

The Intel part's overall score of 49845 places it in the 90th percentile, with its nearest rival being the Intel Core i9-13980HX at 1.1% higher. The AMD part's score of 97453 places it in the 96th percentile, with its nearest rival being the AMD Ryzen Threadripper PRO 5965WX at 1.1% lower. The gap in average benchmark scores between these two processors is roughly 95%, which aligns with the head-to-head data showing the AMD chip winning 13 out of 15 tests.

For users running multithreaded workloads on a mobile platform, the AMD Ryzen 9 9955HX3D is the stronger option. For users needing maximum single-core Cinebench performance on a desktop platform, the Intel Core 9 273PE has a clear advantage, though it remains behind in the broader PassMark suite. The data does not support the Intel part as a general-purpose winner; its strengths are narrowly concentrated in single-threaded Cinebench tasks.
