The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 8945HX belongs to the 8000 series and uses the Zen 4 architecture, specifically the Dragon Range codename. It is built on a 5 nm process at TSMC, containing 13,140 million transistors across a die size of 2x 71 mm². The Intel Core 9 273PE uses the Bartlett Lake codename and is fabricated on a 10 nm process at Intel, with no transistor count or die size recorded in the database.

Cache hierarchies differ substantially. The AMD part allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel part allocates 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. While Intel provides more L1 and L2 per core, AMD's total L3 cache is significantly larger at 64 MB versus 36 MB. The AMD processor is a mobile market segment part using AMD Socket FL1, while the Intel processor is a desktop market segment part using Intel Socket 1700. The AMD part has an unlocked multiplier, and the Intel part does not. Both are listed as Active in production status.

Memory support also diverges. The AMD Ryzen 9 8945HX supports DDR5 memory only, while the Intel Core 9 273PE supports both DDR4 and DDR5. The AMD part does not support ECC memory, while the Intel part does. Integrated graphics differ as well: AMD uses Radeon 610M, Intel uses UHD Graphics 730. The release dates are distinct, with the AMD part released in April 2025 and the Intel part in March 2026.

Specification Differences

The recorded specifications show clear distinctions. The AMD Ryzen 9 8945HX has 16 cores and 32 threads, a base clock of 2.50 GHz, and a boost clock of 5.40 GHz. The Intel Core 9 273PE has fewer resources: 12 cores and 24 threads, a base clock of 2.30 GHz, and a higher boost clock of 5.70 GHz. The Intel part draws more power, with a TDP of 65 watts versus AMD's 55 watts. The AMD part is fabricated on a 5 nm process at TSMC; the Intel part uses a 10 nm process at Intel. The AMD part has 28 PCIe Gen 5 lanes (CPU only), the Intel part has 16. Memory bandwidth favors Intel at 89.6 GB/s versus 83.2 GB/s for AMD. The Intel part supports ECC memory, the AMD part does not. The AMD part has an unlocked multiplier; the Intel part is locked. The Intel part has a recorded launch MSRP of $549; the AMD part has no launch MSRP recorded.

Head-to-Head Benchmarks

The head-to-head data shows AMD dominance across nearly every test. In Cinebench R15 multi-core, AMD scores 4,305 versus Intel's 3,153, a 36.5% lead. The single-core R15 test shows AMD at 607 versus Intel's 445, also a 36.4% delta. Cinebench R20 multi-core has AMD at 17,939 and Intel at 13,140, a 36.5% difference, and R20 single-core shows AMD at 2,532 versus Intel's 1,855, again 36.5%. The pattern continues in Cinebench R23: multi-core 42,713 for AMD versus 31,288 for Intel, and single-core 6,030 versus 4,417, both at a 36.5% delta.

The PassMark suite reveals even larger gaps in certain workloads. Data compression shows AMD at 677,755 versus Intel's 405,885, a 67% lead. Data encryption scores 40,836 for AMD and 22,719 for Intel, a 79.7% delta. Extended instructions see AMD at 49,823 versus Intel's 24,630, an enormous 102.3% lead. Find prime numbers: AMD 262, Intel 203, a 29.1% delta. Floating point math: AMD 117,453, Intel 107,884, a narrower 8.9% lead. Integer math: AMD 195,180, Intel 139,410, a 40% delta. Multithread: AMD 51,405, Intel 36,810, a 39.6% delta. Random string sorting: AMD 78,781, Intel 45,098, a 74.7% delta. Single-thread: AMD 3,907, Intel 3,650, a 7% delta.

The only Intel victory is in PassMark physics, where Intel scores 3,120 and AMD scores 2,168, giving Intel a 30.5% advantage. This is the sole data point where the Intel part outperforms AMD, and it is a substantial one, suggesting a specific architectural strength in physics calculations.

Where Each One Wins

The AMD Ryzen 9 8945HX wins decisively in multi-threaded and single-threaded rendering workloads, as indicated by the consistent 36.5% leads across all Cinebench R15, R20, and R23 tests. It also dominates data-intensive tasks: data compression, encryption, extended instructions, integer math, and random string sorting all show AMD leads ranging from 40% to 102.3%. The AMD part's larger L3 cache and higher core count appear to deliver advantages in these throughput-oriented tasks. For users prioritizing Cinebench-class rendering, data processing, encryption, or general multithreaded compute, the AMD Ryzen 9 8945HX is the stronger performer based on the recorded data.

The Intel Core 9 273PE wins specifically in the PassMark physics test, with a 30.5% advantage over AMD. This single win suggests that the Intel architecture, with its higher boost clock of 5.70 GHz and larger per-core L2 cache of 2 MB, may handle physics simulation workloads more efficiently. The Intel part also supports ECC memory and a higher memory bandwidth of 89.6 GB/s, which could be relevant for specific workstation or server-style use cases where data integrity and memory throughput matter. The Intel part's launch MSRP of $549 provides a reference point, though the database does not record a comparable price for the AMD part. The Intel processor also holds a slight edge in floating point math, though the 8.9% delta is far smaller than its physics win. The overall benchmark record favors AMD in 16 of 17 tests, making the Intel part a niche choice for physics-focused workloads or for users requiring ECC memory support and DDR4 compatibility.
