AMD Ryzen Embedded 8645HS vs Intel Core 9 273PE Comparison

The Verdict

The Intel Core 9 273PE is the clear performance leader in this comparison. The recorded data shows it holds the 90th percentile among all CPUs in the database, while the AMD Ryzen Embedded 8645HS sits at the 50th percentile. The Intel part doubles the core count, doubles the thread count, and offers a higher boost clock. For any workload that scales across cores, the Intel Core 9 273PE delivers results that the AMD chip cannot match.

The AMD Ryzen Embedded 8645HS, however, uses a more advanced 4 nm process node from TSMC, draws less power with a 45 TDP versus the Intel chip's 65 TDP, and integrates a Radeon 760M graphics solution. The Intel part uses a 10 nm Intel process and carries UHD Graphics 730. The AMD chip is built on Zen 4 architecture with the Hawk Point codename, while Intel uses Bartlett Lake.

For users who prioritize multi-threaded throughput, the Intel Core 9 273PE is the only rational choice based on the data. The AMD chip has no recorded benchmark scores in the database, whereas the Intel part has 17 recorded measurements across Cinebench and Passmark tests. The Intel Core 9 273PE also carries a launch MSRP of $549, which appears once in this analysis. The AMD Ryzen Embedded 8645HS has no launch MSRP recorded.

For users who need lower power consumption, ECC memory support, a smaller process node, or a more integrated graphics solution, the AMD Ryzen Embedded 8645HS offers those attributes. Its 45 W TDP is lower, its 4 nm process is more advanced, and its Radeon 760M integrated graphics is likely more capable than Intel's UHD Graphics 730, though the database records no direct graphics benchmarks for either part.

The Intel Core 9 273PE trails the AMD Ryzen AI Max+ 388 by a negligible 0.1 percent, edges out the Intel Core i5-14600KF by 0.9 percent, and trails both the Intel Core i9-13980HX and the AMD Ryzen AI 9 HX PRO 370 by about 1.1 to 1.2 percent.

Since the AMD Ryzen Embedded 8645HS has no benchmark scores, no direct numerical comparison can be made. The percentile rankings, however, tell a clear story. The Intel chip at the 90th percentile is far above the AMD chip at the 50th percentile.

Where Each One Wins

The Intel Core 9 273PE wins decisively in multi-threaded workloads based on its 12 cores, 24 threads, and recorded benchmark scores. The Cinebench R23 multi-core score of 31,288 and the Passmark multithread score of 36,810 demonstrate strong parallel performance. The 5.70 GHz boost clock also gives it an advantage in single-threaded tasks, reflected in the Cinebench R23 single-core score of 4,417 and the Passmark single-thread score of 3,650.

The Intel chip also wins on cache capacity. Its 36 MB of shared L3 cache is more than double the AMD chip's 16 MB. Its larger L1 and L2 caches per core (80 KB and 2 MB versus 64 KB and 1 MB) further favor the Intel part for cache-sensitive workloads.

The Intel chip wins on memory flexibility. It supports both DDR4 and DDR5, while the AMD chip supports only DDR5. This allows the Intel part to work with a broader range of memory modules. The Intel chip also wins on PCIe generation, offering Gen 5 connectivity versus the AMD chip's Gen 4.

The AMD Ryzen Embedded 8645HS wins on power efficiency. Its 45 W TDP is lower than the Intel chip's 65 W TDP. The AMD chip also wins on process technology, using a 4 nm node from TSMC versus Intel's 10 nm node. A smaller process node typically translates to better thermal behavior and lower power draw per transistor.

The AMD chip wins on PCIe lane count. It provides 20 lanes (CPU only) versus the Intel chip's 16 lanes (CPU only). This gives the AMD part more direct connectivity options for peripherals, even though the interface generation is older.

The AMD chip wins on integrated graphics capability. The Radeon 760M is generally positioned as a more capable iGPU than Intel's UHD Graphics 730, though the database records no direct graphics benchmarks for either part. The AMD chip also wins on market segment suitability, being classified as Mobile while the Intel chip is Desktop. For embedded or mobile deployments where power and footprint matter, the AMD chip's profile fits better.

The Intel chip wins on benchmark coverage and database standing. Its 17 recorded scores and 90th percentile ranking provide concrete evidence of performance. The AMD chip's 50th percentile ranking with no recorded scores leaves its performance unverified in the database.

For users who need raw compute throughput, multi-threaded rendering, heavy compilation, or data processing, the Intel Core 9 273PE is the clear choice. For users who need a lower-power embedded processor with ECC memory, a newer process node, and a more capable integrated GPU, the AMD Ryzen Embedded 8645HS presents a compelling alternative. Both parts support ECC memory and dual-channel memory with identical recorded bandwidth of 89.6 GB/s. The decision hinges on whether raw performance or power efficiency and integration matter more for the intended workload.
