Where Each One Wins

The head-to-head benchmark data shows a one-sided result: the Intel Core 9 273PQE wins all 17 recorded comparisons. There are no benchmark categories where the AMD Ryzen 5 PRO 8540U takes a victory. The closest margin for the AMD part appears in single-thread performance, where the Intel processor leads by 22.1% in PassMark single-thread and singlethread tests. The largest margin for the Intel part appears in floating-point math, where it leads by 72.2%.

For workloads that stress parallel execution, the Intel Core 9 273PQE delivers substantially higher multi-threaded throughput. Cinebench R23 multicore shows a score of 39190 for the Intel part versus 15456 for the AMD part. The PassMark multithread test shows 46107 for Intel versus 18218 for AMD. The Intel processor also dominates data compression with a score of 585752 versus 205703, a 64.9% advantage, and integer math with 164629 versus 56738, a 65.5% advantage.

The AMD Ryzen 5 PRO 8540U does not hold a lead in any measured workload category. Its lower core count, lower boost clock, and mobile-oriented design place it behind the Intel desktop part across every benchmark in the database.

Architecture Differences

The AMD Ryzen 5 PRO 8540U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It contains 20,900 million transistors on a 137 mm² die. The Intel Core 9 273PQE uses the Bartlett Lake codename with a 10 nm process at Intel. No transistor count or die size is recorded for the Intel part.

Cache structures differ notably between the two. The AMD processor has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel part therefore offers larger per-core L1 and L2 caches and more than double the shared L3 capacity.

The Verdict

The benchmark data favors the Intel Core 9 273PQE in every recorded category. The Intel part doubles the core count, offers a 1.00 GHz higher boost clock, and carries more cache at every level. Its average benchmark score of 66099 places it in the 93rd percentile of all CPUs, while the AMD Ryzen 5 PRO 8540U sits in the 76th percentile with an average score of 23709.

For workloads that depend on multi-threaded performance, the Intel part is the clear choice. Cinebench R23 multicore shows a 60.6% lead, and PassMark multithread shows a 60.5% lead. For single-thread responsiveness, the Intel part also leads, though by a smaller 22.1% margin in PassMark single-thread tests. The Intel part's 5.90 GHz boost clock and larger L2 and L3 caches support these results.

The AMD Ryzen 5 PRO 8540U remains a 28 W mobile processor with a 4 nm process and a smaller physical footprint. Its advantage lies in power efficiency and mobile integration, not in raw performance. The data records no benchmark category where it outperforms the Intel part. The Intel Core 9 273PQE, with its 125 W TDP, desktop socket, and PCIe Gen 5 support, targets desktop builds that prioritize throughput.

The recorded data indicates that the Intel Core 9 273PQE outperforms the AMD Ryzen 5 PRO 8540U by margins ranging from 22.1% in single-thread tests to 72.2% in floating-point math. The AMD part's nearest rival tier, around 23709 average score, aligns with desktop processors from several generations ago, while the Intel part competes with the AMD Ryzen 9 7950X3D and Intel Core Ultra 5 250K Plus. The selection between these two parts depends on the intended platform: mobile efficiency points to the AMD processor, while maximum performance points to the Intel processor.
