AMD Ryzen 5 PRO 8640HS vs Intel Core 9 273PTE Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall victory for the Intel Core 9 273PTE, which wins 12 of the 17 recorded comparisons. The AMD Ryzen 5 PRO 8640HS takes 5 wins, but those wins are concentrated in specific workloads where its architecture provides a measurable edge. Across the Cinebench suite, the Intel part leads consistently by roughly 11.4 to 11.5 percent in both single-core and multi-core tests. In Cinebench R23 multi-core, the Intel scores 20,445 against the AMD's 18,104, a gap that matches the pattern seen in R15 and R20. Single-core R23 shows the same margin: 2,886 for Intel versus 2,555 for AMD.

The Intel part's advantage extends into PassMark's math-heavy tests. In floating point math, it posts 60,673 against 43,019, a 29.1 percent lead. Integer math goes to Intel by 15.3 percent, with scores of 82,411 and 69,839. The largest single delta in the entire comparison appears in prime number finding, where Intel scores 142 against AMD's 71, a 50 percent difference. Physics also favors Intel heavily: 1,917 versus 1,043, a 45.6 percent gap. Multithread performance in PassMark shows Intel at 24,054 versus 21,465, an 10.8 percent lead, and data compression goes to Intel by 4.7 percent with scores of 258,704 and 246,446.

The AMD Ryzen 5 PRO 8640HS, however, wins the encryption test decisively. Its PassMark data encryption score of 14,962 beats Intel's 14,253 by 5 percent. Extended instructions show an even larger AMD advantage: 18,507 versus 15,952, a 16 percent lead. Random string sorting goes to AMD by 4.4 percent, with scores of 30,235 and 28,973. In single-thread PassMark testing, AMD records 3,561 against Intel's 3,433, a 3.7 percent win. That result appears twice in the data, under both "single_thread" and "singlethread" labels, confirming the consistency of that measurement.

The overall average benchmark score reflects the split: Intel sits at 31,143, which places it in the 82nd percentile of all CPUs in the database. AMD's average is 28,478, in the 80th percentile. The nearest rival data reinforces the positioning. Intel's closest competitor is the Intel Core i7-12700F, which scores 31,081 and trails by 0.2 percent. The AMD Ryzen 9 8945HS also scores 31,074, again 0.2 percent behind Intel. For the AMD part, its nearest rival is the Intel Xeon E-2436 at 28,530, which is 0.2 percent ahead, and the AMD Ryzen 7 PRO 6850HS at 28,549, also 0.2 percent ahead. The AMD Ryzen 7 PRO 6850U trails the Ryzen 5 PRO by 0.3 percent.

The Verdict

The data indicates that the Intel Core 9 273PTE is the stronger processor for general compute and multi-threaded workloads. It wins every Cinebench test, all but two of the PassMark math tests, and the multithread and compression tests. The 12-core, 24-thread configuration with a 5.50 GHz boost clock delivers results that consistently place it ahead of the AMD part in raw throughput. The AMD Ryzen 5 PRO 8640HS, with 6 cores and 12 threads, cannot match that core count, and the benchmark results show the expected gap in heavily parallel tasks.

The AMD part is not without merit. Its wins in encryption, extended instructions, random string sorting, and single-thread PassMark indicate that its Zen 4 architecture handles certain instruction patterns more efficiently. The 5 percent encryption lead and the 16 percent extended instructions lead suggest that specific workloads, particularly those involving cryptographic operations or specialized instruction sets, will see better performance on the AMD side. The single-thread PassMark win, despite a lower boost clock of 4.90 GHz versus 5.50 GHz, points to higher instructions per clock in that particular test.

For users selecting between these two, the choice hinges on workload type. The Intel part is the default pick for rendering, physics simulation, prime number computations, and any task that scales with core count. The AMD part is preferable for encryption-heavy processes and for single-threaded PassMark-style workloads where it posts a 3.7 percent advantage. The overall percentile ranking, 82nd for Intel versus 80th for AMD, reflects the Intel part's broader superiority, but the margin in the database's average score, 31,143 versus 28,478, is about 9.4 percent, which is meaningful but not overwhelming.

Where Each One Wins

The Intel Core 9 273PTE dominates in multi-core rendering. Cinebench R15, R20, and R23 multi-core scores all favor Intel by 11.4 to 11.5 percent. The physics test shows a particularly large gap, with Intel leading by 45.6 percent, indicating strong performance in simulation-style workloads. Prime number finding, a test that stresses integer throughput and loop efficiency, also goes heavily to Intel with a 50 percent lead. Floating point math, integer math, and multithread tests all fall in Intel's column with leads ranging from 10.8 to 29.1 percent. Data compression is a narrower win for Intel at 4.7 percent.

The AMD Ryzen 5 PRO 8640HS wins in encryption, where its 5 percent lead suggests efficient cryptographic instruction handling. Extended instructions show a 16 percent advantage, the largest AMD win in the entire set. Random string sorting goes to AMD by 4.4 percent, and the single-thread PassMark test shows AMD ahead by 3.7 percent. These wins are all in specialized or lightly threaded tasks, which aligns with the AMD part's lower core count and higher base clock of 3.50 GHz versus Intel's 1.40 GHz. The base clock difference is notable: AMD's 3.50 GHz base is substantially higher, which likely contributes to its single-thread PassMark win despite the lower boost ceiling.

Architecture Differences

The two processors come from different design philosophies and foundries. The AMD Ryzen 5 PRO 8640HS uses the Zen 4 architecture, codenamed Hawk Point, built on a 4 nm process at TSMC. It contains 25,000 million transistors on a die size of 178 mm². The Intel Core 9 273PTE uses the Bartlett Lake codename, built on a 10 nm process at Intel. No transistor count or die size is recorded for the Intel part.

Cache hierarchies differ substantially. The AMD part has 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The larger L3 cache on the Intel side, more than double that of AMD, likely contributes to its performance in data-heavy workloads.

Memory support also differs. The AMD processor supports DDR5 only, while the Intel processor supports both DDR4 and DDR5. Both use dual-channel memory buses and have identical memory bandwidth of 89.6 GB/s. Both support ECC memory.

The newer PCIe standard on the Intel side provides higher potential bandwidth for compatible devices.

Integrated graphics differ as well. The AMD Ryzen 5 PRO 8640HS includes Radeon 760M graphics, while the Intel Core 9 273PTE includes UHD Graphics 730. The market segments also differ: AMD is classified as Mobile, Intel as Desktop. The AMD part uses AMD Socket FP7, while Intel uses Intel Socket 1700.

Specification Differences

The core and thread counts are the most obvious difference: 6 cores and 12 threads for AMD versus 12 cores and 24 threads for Intel. Base clocks diverge sharply, with AMD at 3.50 GHz and Intel at 1.40 GHz. Boost clocks also differ, with Intel reaching 5.50 GHz and AMD reaching 4.90 GHz. Thermal design power reflects the performance envelope: AMD is rated at 28 watts, Intel at 45 watts. The AMD part is built on a 4 nm process, the Intel part on 10 nm. Manufacturing is split between TSMC for AMD and Intel for the Intel part. The AMD processor is unlocked for overclocking? No, both have locked multipliers, as neither shows an unlocked status. Release dates differ: AMD launched on 2024-04-15, Intel on 2026-03-08. The Intel part has a launch MSRP of $549. The AMD part has no recorded launch MSRP. Part numbers also differ: AMD lists 100-000001354(FP7r2) and 100-000001382(FP7), while Intel lists SA4QJ.
