The Verdict

The recorded data shows a complete sweep for the Intel Core 9 273PE. Across all 17 head-to-head benchmark comparisons, the Intel processor wins every single test. The AMD Ryzen 5 PRO 5655G records zero wins. This is not a close contest; the Intel part delivers substantially higher scores in every measured workload.

For users prioritizing raw multi-core throughput, the Intel Core 9 273PE is the clear selection. Its 12 cores and 24 threads double the thread count of the AMD part, and the benchmark results confirm the advantage. The Intel chip scores 31,288 in Cinebench R23 multi-core, which is 81.4% higher than the AMD chip's 17,249.

The Intel part also wins decisively in single-thread performance. Its Cinebench R23 single-core score of 4,417 is 81.4% higher than the AMD's 2,435. This suggests the Intel architecture delivers stronger per-core performance despite the AMD chip's higher base clock of 3.90 GHz versus 2.30 GHz.

The AMD Ryzen 5 PRO 5655G remains a viable option only in contexts where its smaller footprint matters. It uses a 7 nm process versus Intel's 10 nm, and it draws the same 65 W TDP. However, the benchmark data does not reveal any workload where the AMD chip comes out ahead. The Intel Core 9 273PE is the superior processor across the entire test suite.

Head-to-Head Benchmarks

The largest margin comes in PassMark physics, where the Intel Core 9 273PE scores 3,120 versus 686 for the AMD Ryzen 5 PRO 5655G, a 78% advantage. This test often reflects complex instruction handling and multi-thread efficiency, which the Intel part's higher core count supports.

Floating point math shows a 64.2% gap. The Intel chip records 107,884, while the AMD chip manages 38,649. This workload benefits from the Intel part's larger cache hierarchy and additional cores.

Find prime numbers shows a 75.9% difference: 203 for Intel versus 49 for AMD. This is one of the largest proportional gaps in the entire dataset, indicating the Intel architecture handles integer-heavy iterative workloads far more efficiently.

Integer math follows a similar trend. The Intel Core 9 273PE scores 139,410 against 67,561 for the AMD part, a 51.5% lead. Data compression shows 405,885 versus 255,608, a 37% difference. Data encryption records 22,719 versus 15,253, a 32.9% gap.

The Cinebench tests all show a uniform 44.9% delta. In Cinebench R15, the Intel chip scores 3,153 multi-core and 445 single-core, while the AMD chip scores 1,738 and 245 respectively. Cinebench R20 follows the same pattern: 13,140 versus 7,244 multi-core, and 1,855 versus 1,022 single-core.

PassMark single-thread shows the smallest margin at 11.2%. The Intel part scores 3,650, and the AMD part scores 3,241. This indicates that while the Intel chip still wins, the per-core performance gap is much narrower than the multi-thread gaps.

Random string sorting shows a 44% lead for Intel: 45,098 versus 25,253. Extended instructions record 24,630 versus 17,944, a 27.1% difference. Multithread scores 36,810 versus 19,129, a 48% advantage.

Specification Differences

The Intel Core 9 273PE has 12 cores and 24 threads, double the AMD Ryzen 5 PRO 5655G's 6 cores and 12 threads. The AMD part has a base clock of 3.90 GHz and a boost clock of 4.40 GHz. The Intel part has a base clock of 2.30 GHz but a boost clock of 5.70 GHz.

Both processors have a 65 W TDP. The AMD chip uses AMD Socket AM4, while the Intel chip uses Intel Socket 1700. The AMD part is based on the Zen 3 architecture with the Cezanne codename. The Intel part uses the Bartlett Lake codename.

The AMD Ryzen 5 PRO 5655G uses a 7 nm process from TSMC with 10,700 million transistors on a 180 mm² die. The Intel Core 9 273PE uses a 10 nm process from Intel; the database does not list transistor count or die size for the Intel part.

Cache configurations differ substantially. The AMD chip has 64 KB L1 per core, 512 KB L2 per core, and 16 MB L3. The Intel chip has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3.

Memory support differs. The AMD part supports DDR4 only with dual-channel memory and 51.2 GB/s bandwidth. The Intel part supports both DDR4 and DDR5 with dual-channel memory and 89.6 GB/s bandwidth. Both support ECC memory.

PCIe generations differ. The AMD chip uses Gen 3 with 16 CPU lanes. The Intel chip uses Gen 5 with 16 CPU lanes. Integrated graphics also differ: the AMD chip has Radeon Vega 7, while the Intel chip has UHD Graphics 730.

The release dates differ. The AMD Ryzen 5 PRO 5655G launched on 2024-05-06. The Intel Core 9 273PE launched on 2026-03-08. The Intel part has a launch MSRP of $549; the AMD part has no listed launch MSRP.

Architecture Differences

The AMD Ryzen 5 PRO 5655G uses the Zen 3 architecture, built on a 7 nm TSMC process. This is a mature design with 6 cores and 12 threads. The architecture relies on a smaller L3 cache of 16 MB and per-core L2 of 512 KB. The process node gives the AMD part a transistor density advantage, with 10,700 million transistors packed into 180 mm².

The Intel Core 9 273PE uses the Bartlett Lake codename, built on Intel's 10 nm process. This architecture provides 12 cores and 24 threads. The L3 cache is 36 MB shared, and each core has 2 MB L2, which is four times the per-core L2 of the AMD part. The larger cache hierarchy likely contributes to the Intel chip's strong performance in cache-sensitive workloads like data compression and random string sorting.

The boost clock difference is notable. The Intel part reaches 5.70 GHz, while the AMD part tops out at 4.40 GHz. This 1.30 GHz gap in boost frequency helps explain the single-thread performance difference, even though the AMD part has a higher base clock.

Memory architecture also differs. The Intel part supports DDR5 with a theoretical bandwidth of 89.6 GB/s, which is 75% higher than the AMD part's 51.2 GB/s DDR4 bandwidth. This could influence memory-heavy workloads, though the benchmark data does not isolate memory bandwidth effects.

PCIe Gen 5 on the Intel part provides higher bandwidth for attached devices compared to Gen 3 on the AMD part. This does not directly affect CPU benchmarks but matters for system-level expansion.

Where Each One Wins

The Intel Core 9 273PE wins every benchmark in the database. No workload favors the AMD Ryzen 5 PRO 5655G. The Intel part's largest margins appear in physics simulation (78% lead), prime number finding (75.9%), and floating point math (64.2%). These workloads benefit from the Intel chip's 12 cores, 24 threads, and larger caches.

The smallest Intel advantage is in PassMark single-thread at 11.2%. This suggests that in lightly threaded tasks, the AMD chip's higher base clock narrows the gap, but the Intel part still comes out ahead. The Intel boost clock of 5.70 GHz likely drives this win.

For multi-threaded rendering workloads, the Cinebench results show a consistent 44.9% Intel lead across R15, R20, and R23. The Intel chip's thread count advantage is fully realized in these tests. The AMD chip's 6 cores and 12 threads simply cannot match the throughput of the Intel part's 12 cores and 24 threads.

The AMD Ryzen 5 PRO 5655G does not have a single recorded win. Its only potential advantages are qualitative: the 7 nm process node suggests better power efficiency per transistor, and the smaller die size may offer lower manufacturing costs. However, the benchmark data shows no workload where these factors translate into a performance win.

The Intel Core 9 273PE is the universal choice based on the recorded metrics. Its 90th percentile standing across all CPUs, versus the AMD part's 80th percentile, confirms the overall positioning. For any application that uses the measured benchmarks, the Intel processor delivers higher scores.
