Where Each One Wins

The Intel Core 9 273PTE is the clear winner in raw multi-threaded performance based on the recorded benchmark data. Across every Cinebench multi-core test in the database, the Intel part delivers substantially higher scores. In Cinebench R15 multi-core, it scores 2,060 points, while Cinebench R20 multi-core shows 8,586 points and Cinebench R23 multi-core shows 20,445 points. The AMD part has no recorded benchmark scores in the database, so all comparisons rely on the Intel data alone.

The Intel part also wins in single-threaded performance as indicated by its Cinebench scores. It records 290 points in Cinebench R15 single-core, 1,212 points in Cinebench R20 single-core, and 2,886 points in Cinebench R23 single-core. The PassMark single-thread test shows a score of 3,433, confirming strong per-core performance despite the lower base clock.

In specialized PassMark workloads, the Intel part demonstrates particular strength in integer math with a score of 82,411 and floating-point math with a score of 60,673. Data compression is also a strong area, scoring 258,704 in the PassMark data compression test. The multithreaded PassMark score of 24,054 and physics score of 1,917 further indicate balanced performance across different workload types.

The AMD Ryzen Embedded 8640U has no benchmark entries in the database, so there are no recorded wins for this processor. Its advantages lie in its specifications rather than measured performance: a lower TDP of 28 watts versus 45 watts, a smaller 4 nm process node versus 10 nm, and a more compact die size of 178 mm² versus no recorded die size for the Intel part. The AMD processor also supports PCIe Gen 4 with 20 lanes, while the Intel part supports PCIe Gen 5 with 16 lanes.

Architecture Differences

The AMD Ryzen Embedded 8640U uses the Zen 4 architecture with the Hawk Point codename, belonging to the 8000 series. The Intel Core 9 273PTE uses the Bartlett Lake codename from the Core 9 generation. The AMD part is built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The Intel part is built on a 10 nm process at Intel, with no transistor count or die size recorded in the database.

Cache hierarchies differ significantly between the two. The AMD part provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel part provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The larger per-core L1 and L2 caches on the Intel part, combined with more than double the L3 cache, support its higher core count and thread count.

Memory support shows a split: the AMD part supports only DDR5 memory, while the Intel part supports both DDR4 and DDR5. Both use a dual-channel memory bus with identical memory bandwidth of 89.6 GB/s. ECC memory is enabled on both processors.

The integrated graphics differ in branding and capability. The AMD part includes Radeon 760M graphics, while the Intel part includes UHD Graphics 730. The PCIe interface also differs: the AMD part uses Gen 4 with 20 CPU lanes, and the Intel part uses Gen 5 with 16 CPU lanes. The AMD part targets the mobile market segment with an AMD Socket FP8, while the Intel part targets the desktop segment with an Intel Socket 1700.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the AMD Ryzen Embedded 8640U has no individual benchmark scores recorded. Therefore, all performance analysis must be based on the Intel Core 9 273PTE's benchmark results and its position relative to nearest rivals.

The Intel Core 9 273PTE achieves an average benchmark score of 31,143, placing it in the 82nd percentile of all CPUs in the database. This places it 0.2% above the Intel Core i7-12700F which scores 31,081, and 0.2% above the AMD Ryzen 9 8945HS which scores 31,074. It is 0.4% above the Intel Core i7-13700TE at 31,028, and 0.5% below the Intel Core i7-12650HX at 31,290. These small deltas indicate that the Intel Core 9 273PTE sits in a tight performance cluster with these four rivals.

In Cinebench R23 multi-core, the Intel part scores 20,445 points, which reflects strong scaling from its 12 cores and 24 threads. The R20 multi-core score of 8,586 and R15 multi-core score of 2,060 follow the expected progression across Cinebench versions. Single-core performance is also solid: 2,886 in R23, 1,212 in R20, and 290 in R15.

PassMark results show where the Intel part excels. The data compression score of 258,704 is the highest single metric in the benchmark suite, indicating strong memory subsystem performance. Integer math at 82,411 and floating-point math at 60,673 show balanced arithmetic capability. The multithread score of 24,054 aligns with the core count, while the single-thread score of 3,433 confirms the high boost clock of 5.50 GHz translates into per-core throughput.

Extended instructions score 15,952, data encryption scores 14,253, random string sorting scores 28,973, and find prime numbers scores 142. The physics score of 1,917 rounds out the recorded benchmarks. With no AMD benchmark data available, the comparison between these two specific processors cannot be quantified directly. The database indicates the Intel part is a high-percentile performer, while the AMD part's specifications suggest a lower-power mobile design with a smaller core count and lower TDP.
