CPU Comparison

The Intel Core 9 273PTE and AMD Ryzen 9 8945HS are remarkably close in overall performance, with average benchmark scores of 31143 and 31074 respectively, a difference of only 0.2%. Both chips sit at the 82nd percentile among all CPUs, and their nearest rival lists are nearly identical, featuring the Intel Core i7-12700F and Intel Core i7-13700TE. Despite this statistical tie, the two processors achieve their results through very different strengths: the Intel part wins on raw single-threaded and specific compute tasks, while the AMD part dominates in data processing and multi-threaded workloads.

Head-to-Head Benchmarks

The most striking single result belongs to the Intel Core 9 273PTE in Cinebench R23 single-core, where it scores 2886 against the Ryzen’s 1805, a massive 59.9% advantage. This is not a small edge; it is a generational gap in single-thread performance. The Intel chip also wins Cinebench R23 multi-core with 20445 versus 16795, a 21.7% lead, and takes Cinebench R15 single-core by a narrower 3.2% margin (290 vs 281).

However, the AMD Ryzen 9 8945HS strikes back hard in the Passmark suite. Its data compression score of 356508 crushes the Intel’s 258704, a 27.4% deficit for Intel. Data encryption shows a similar story: AMD scores 21323 versus Intel’s 14253, a 33.2% gap. The biggest AMD win comes in extended instructions, where it posts 26964 against Intel’s 15952, a 40.8% advantage. Random string sorting also favors AMD heavily (43202 vs 28973, a 32.9% delta), and integer math goes to AMD by 18.6% (101226 vs 82411).

The multi-threaded Passmark result is a clear AMD win: 29780 versus 24054, a 19.2% margin. AMD also takes Passmark single-thread at 3850 versus 3433, a 10.8% lead, and floating point math by a slim 1.9% (61821 vs 60673). Intel’s remaining wins are more specialized: it leads in find prime numbers by 54.3% (142 vs 92) and in physics by 33.7% (1917 vs 1434). Notably, AMD wins the older Cinebench R15 multi-core test by 22% (2640 vs 2060), which contrasts sharply with its 21.7% loss in R23 multi-core, a sign that the two chips scale very differently across workloads and test versions.

The Verdict

The data points to a clear split. Choose the Intel Core 9 273PTE if your work is dominated by single-threaded performance or by applications that mirror Cinebench R23’s scaling. The 59.9% single-core lead and 21.7% multi-core lead in that benchmark are decisive. This chip also excels in prime-number finding and physics calculations, suggesting strength in scientific and simulation workloads.

Choose the AMD Ryzen 9 8945HS for data-heavy tasks. It wins 10 of the 15 head-to-head comparisons, and its victories in compression, encryption, and extended instructions show a processor tuned for throughput and security-related workloads. The 19.2% lead in Passmark multi-thread is substantial, and even in single-threaded Passmark testing it beats Intel by 10.8%. For a mobile platform (Socket FP8), the Ryzen delivers exceptional data-crunching capability that outpaces a desktop-oriented Intel part in most measured scenarios.

The overall average scores are nearly identical, the AMD chip trails by just 0.2%, so the choice comes down to workload, not raw capability. The Intel chip is the specialist; the AMD chip is the generalist with a data-processing edge.

Architecture Differences

The two CPUs come from fundamentally different design philosophies. Intel’s Core 9 273PTE is built on a 10 nm process at Intel’s own foundry, using the Bartlett Lake codename and a desktop market segment. It packs 12 cores and 24 threads, with a base clock of 1.40 GHz and a boost clock of 5.50 GHz. The AMD Ryzen 9 8945HS is a mobile part from the 8000 series, built on TSMC’s 4 nm process with the Hawk Point codename and Zen 4 architecture. It has 8 cores and 16 threads, with a much higher base clock of 4.00 GHz but a lower boost clock of 5.20 GHz.

Cache configurations differ significantly. Intel allocates 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. AMD provides 64 KB L1 per core, 1 MB L2 per core, and only 16 MB of shared L3. The Intel chip’s larger L3 cache (36 MB vs 16 MB) likely contributes to its strong Cinebench results, while AMD’s smaller cache is offset by its higher base clock and denser process node.

Memory support also diverges. Intel supports both DDR4 and DDR5, while AMD only supports DDR5. Both run dual-channel with identical 89.6 GB/s memory bandwidth. Intel supports ECC memory; AMD does not. PCIe connectivity is a major difference: Intel offers Gen 5 with 16 lanes, while AMD offers Gen 4 with 20 lanes. The integrated graphics differ as well, Intel uses UHD Graphics 730, while AMD uses the Radeon 780M, which is typically a more capable iGPU. The AMD chip has a transistor count of 25,000 million on a 178 mm² die, while Intel does not disclose these figures.

Where Each One Wins

The Intel Core 9 273PTE is the clear winner in single-threaded performance, as evidenced by its 59.9% lead in Cinebench R23 single-core and its 3.2% win in Cinebench R15 single-core. It also dominates in prime number finding (54.3% faster) and physics calculations (33.7% faster), making it a strong choice for computational science, financial modeling, and any application that relies heavily on branch prediction and integer logic. Its 21.7% win in Cinebench R23 multi-core also suggests it scales well in modern rendering tasks, despite having fewer Passmark multi-thread wins.

The AMD Ryzen 9 8945HS wins in virtually every data-intensive category. Its 40.8% lead in extended instructions and 33.2% lead in encryption point to advantages in cryptography, compression, and vectorized code. The 27.4% win in data compression and 32.9% win in random string sorting make it ideal for database work, file archiving, and text processing. Its 19.2% lead in Passmark multi-thread and 18.6% lead in integer math indicate strong general-purpose throughput, while its 10.8% win in single-threaded Passmark shows it also holds its own in lighter tasks.

For gaming, the data is indirect but suggestive. The AMD chip’s iGPU is the Radeon 780M, while Intel uses UHD Graphics 730, so the AMD part is likely better for integrated graphics gaming. However, the Intel chip’s massive single-core lead in Cinebench R23 could benefit CPU-bound titles. The choice ultimately depends on whether the workload favors Intel’s single-thread dominance or AMD’s data-processing prowess.

The Intel chip offers a higher boost clock, more cores and threads, a larger L3 cache, and ECC support. The AMD chip counters with a significantly higher base clock, a smaller and denser process node, more PCIe lanes, and a more powerful integrated GPU. The Intel part also supports older DDR4 memory, which can lower platform costs, while AMD is limited to DDR5. Both run at 45 W TDP and have locked multipliers, so neither offers manual overclocking. The Intel chip was released on 2026-03-08, while the AMD chip came out on 2023-12-05, making the AMD part the older design, yet it still manages to win the majority of benchmark comparisons.
