These are the only two benchmarks where the performance difference falls below 14%. All other tests show AMD leading by at least 84.5%, which occurs in find prime numbers (262 versus 142).

Specification Differences

The AMD Ryzen 9 8945HX and Intel Core 9 273PTE differ across nearly every core specification. AMD has 16 cores and 32 threads; Intel has 12 cores and 24 threads. Base clocks are 2.50 GHz versus 1.40 GHz. Boost clocks are 5.40 GHz versus 5.50 GHz, giving Intel a 0.10 GHz edge. TDP is 55 watts for AMD versus 45 watts for Intel.

Cache configurations also differ. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 64 MB L3. Intel uses 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. AMD's L3 cache is 64 MB, which is 28 MB larger than Intel's 36 MB.

Memory support differs. AMD supports DDR5 only, with dual-channel memory and 83.2 GB/s bandwidth. Intel supports DDR4 and DDR5, dual-channel, with 89.6 GB/s bandwidth. Intel also supports ECC memory; AMD does not.

PCIe lanes differ. AMD provides Gen 5 with 28 lanes (CPU only). Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well: AMD uses Radeon 610M, while Intel uses UHD Graphics 730.

The multiplier is unlocked on the AMD part but locked on the Intel part. The AMD part numbers 100-000001848; the Intel part numbers SA4QJ. The Intel Core 9 273PTE has a launch MSRP of $549.

Architecture Differences

The AMD Ryzen 9 8945HX is built on Zen 4 architecture with the codename Dragon Range, part of the 8000 series and Ryzen 9 generation. It uses a 5 nm process from TSMC, with 13,140 million transistors and a die size of 2x 71 mm². The Intel Core 9 273PTE uses Bartlett Lake architecture with the Core 9 generation, built on a 10 nm process from Intel. Intel's transistor count and die size are not recorded in the database.

AMD's cache hierarchy uses per-core L1 and L2 with a shared 64 MB L3. Intel uses per-core L1 and L2 with a shared 36 MB L3. AMD's L1 is 64 KB per core, while Intel's is 80 KB per core. AMD's L2 is 1 MB per core; Intel's is 2 MB per core.

AMD's architecture is designed for mobile platforms, using AMD Socket FL1. Intel's Bartlett Lake targets desktop platforms, using Intel Socket 1700. The process node difference (5 nm versus 10 nm) gives AMD a manufacturing advantage in density, though the database does not include direct performance-per-watt measurements.

The AMD part includes a Radeon 610M integrated GPU, while Intel includes UHD Graphics 730. Both support PCIe Gen 5, but AMD offers 28 lanes versus Intel's 16 lanes. AMD's memory bandwidth is 83.2 GB/s; Intel's is 89.6 GB/s.

The unlocked multiplier on AMD allows overclocking, while Intel's locked multiplier prevents it. The Intel part supports ECC memory, a feature absent on AMD. The Intel part also supports DDR4, which may be relevant for systems reusing older memory modules.

Where Each One Wins

The AMD Ryzen 9 8945HX wins every benchmark in the database. Its most dominant areas are extended instructions (212.3% ahead), data encryption (186.5%), random string sorting (171.9%), and data compression (162%). These results indicate AMD is particularly strong in encryption, compression, and instruction-heavy workloads. Multi-core rendering tests show a consistent 108.9% to 109.3% lead across Cinebench R15, R20, and R23.

The AMD part is the clear choice for rendering, video encoding, data compression, encryption, and any workload that scales with core count. Its 16 cores and 32 threads provide double the thread count of the Intel part. The larger 64 MB L3 cache may contribute to the substantial leads in data-heavy tasks.

The Intel Core 9 273PTE has no benchmark wins, but its specification sheet offers select advantages. ECC memory support makes it suitable for error-sensitive computing environments. The lower 45 watt TDP suggests lower power draw. The higher boost clock of 5.50 GHz gives it a slight single-thread clock advantage, though the recorded single-thread benchmark still shows AMD ahead by 13.8%. DDR4 support may be useful for existing DDR4-based systems.

The Intel part also carries a launch MSRP of $549, which is recorded in the database. The AMD part has no recorded launch MSRP.

For users prioritizing raw performance across all measured categories, the AMD Ryzen 9 8945HX is the only choice with any benchmark wins. For users requiring ECC memory or DDR4 compatibility, the Intel Core 9 273PTE offers those features, but with significantly lower benchmark scores across the board. The database records zero benchmark wins for Intel, making this comparison one-sided in performance terms.
