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

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Ryzen Embedded 8645HS and the Intel Core 9 273PQE. The Intel part holds benchmark scores across every measured test, while the AMD processor has no recorded benchmark results in the database. This makes direct score comparisons impossible, but the Intel Core 9 273PQE delivers a complete set of measurements that define its standing.

In Cinebench R15 multicore, the Intel Core 9 273PQE scores 3950 points. Its single-core result in the same test is 557 points. Moving to Cinebench R20, the multicore score rises to 16459, with a single-core score of 2323. Cinebench R23 shows a multicore score of 39190 and a single-core score of 5532. These numbers place the Intel processor in the 93rd percentile of all CPUs in the database, with an average benchmark score of 66099.

The AMD Ryzen Embedded 8645HS has a percentile ranking of 50 and an average benchmark score of 0, which indicates no recorded performance data. The database lists no wins for either side in head-to-head comparisons, and no nearest rivals for the AMD part. The Intel processor, by contrast, has four nearest rivals with tightly clustered scores. The Intel Core Ultra 5 250KF Plus averages 66159, a delta of negative 0.1 percent relative to the Core 9 273PQE. The AMD Ryzen 9 7950X3D scores 65914, a delta of positive 0.3 percent. The Intel Core Ultra 5 250K Plus averages 66855, a delta of negative 1.1 percent, and the AMD EPYC 4465P averages 66925, a delta of negative 1.2 percent. These deltas indicate the Core 9 273PQE sits within roughly one percent of all four rivals, making it a highly competitive part in its measured tier.

PassMark tests reinforce the Intel processor's position. Data compression scores 585752, data encryption scores 29636, and extended instructions score 38743. Find prime numbers scores 198, floating point math scores 125546, and integer math scores 164629. The multithread score is 46107, physics scores 2754, and random string sorting scores 53167. Single-thread performance is recorded twice, at 4573 in both passmark_single_thread and passmark_singlethread. These results show consistent strength across integer, floating-point, and mixed workloads.

The absence of AMD benchmark data means the analysis hinges on architectural and specification differences rather than measured head-to-head results. The Intel processor's 93rd percentile standing, supported by a full benchmark suite, contrasts sharply with the AMD part's 50th percentile placeholder and zero average score.

Architecture Differences

The two processors diverge fundamentally in design approach. The AMD Ryzen Embedded 8645HS uses the Zen 4 architecture with the Hawk Point codename, fabricated on a 4 nm process at TSMC. It contains 25,000 million transistors on a die size of 178 mm². The Intel Core 9 273PQE uses the Bartlett Lake codename, built on a 10 nm process at Intel's own foundry. Transistor count and die size are not recorded for the Intel part.

Core configurations differ substantially. The AMD processor offers 6 cores and 12 threads, while the Intel processor provides 12 cores and 24 threads, exactly double in both categories. Base clocks favor AMD at 4.30 GHz versus Intel's 3.40 GHz, but boost clocks favor Intel at 5.90 GHz versus AMD's 5.00 GHz. The Intel part reaches a higher maximum frequency despite the lower base.

Cache hierarchies also differ. AMD uses 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Intel uses 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The Intel processor holds more than double the L3 capacity, which benefits workloads with large working sets.

Process node advantages belong to AMD. The 4 nm TSMC process is considerably more advanced than Intel's 10 nm node, which typically translates to higher transistor density and lower power draw per operation. However, the Intel part compensates with a higher core count and larger caches.

Memory support differs as well. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use a dual-channel memory bus, and both achieve 89.6 GB/s memory bandwidth. Both processors support ECC memory, which matters for embedded and server applications.

PCIe capabilities show a generation gap. AMD provides PCIe Gen 4 with 20 lanes from the CPU, while Intel provides PCIe Gen 5 with 16 lanes from the CPU. The Intel part uses a newer PCIe standard but fewer lanes. Integrated graphics differ too: AMD includes a Radeon 760M, while Intel includes UHD Graphics 770.

Socket and market segment separate the parts further. AMD uses Socket FP8 and targets the mobile segment, while Intel uses Socket 1700 and targets the desktop segment. Release dates also differ, with AMD launching on 2024-04-01 and Intel on 2026-03-08. The Intel part has a recorded launch MSRP of $589, while AMD has no recorded MSRP. Neither processor has an unlocked multiplier.

The Verdict

The data presents a clear picture. The Intel Core 9 273PQE is a fully measured processor with strong scores across every benchmark category. Its 93rd percentile ranking and average score of 66099 place it among high-performing desktop CPUs, within one percent of rivals like the AMD Ryzen 9 7950X3D and Intel Core Ultra 5 250K Plus. The AMD Ryzen Embedded 8645HS, by contrast, has no recorded benchmark scores, no nearest rivals, and a placeholder percentile of 50.

For workloads that rely on multicore throughput, the Intel processor's 12 cores and 24 threads, combined with 36 MB of L3 cache, deliver measured results like 39190 in Cinebench R23 multicore and 164629 in PassMark integer math. Single-thread performance is also strong, with 5532 in Cinebench R23 single-core and 4573 in PassMark single-thread tests.

The AMD part offers advantages in process technology and power efficiency on paper. The 4 nm node and 45 W TDP suggest lower power consumption than the Intel part's 125 W TDP, but no benchmark data confirms actual performance. The AMD processor's 6 cores and 12 threads, with a 5.00 GHz boost clock, would likely trail the Intel part in heavily threaded workloads, though the database does not provide measured confirmation.

The Intel Core 9 273PQE is the only option with empirical support in this comparison. Its benchmark suite covers rendering, math, compression, encryption, and physics tests, all showing competitive or superior scores relative to its nearest rivals. The AMD Ryzen Embedded 8645HS remains an unmeasured entity, making any performance claim unsupported by the recorded data.

Where Each One Wins

The Intel Core 9 273PQE wins in every category where measured data exists. Multicore workloads benefit from the 12-core, 24-thread configuration and 36 MB of L3 cache. Cinebench R23 multicore at 39190 and PassMark multithread at 46107 confirm strong scaling across many threads. Single-thread performance also favors Intel, with a 5.90 GHz boost clock producing 5532 in Cinebench R23 single-core and 4573 in PassMark single-thread.

Memory flexibility favors Intel, as it supports both DDR4 and DDR5, allowing systems to use either memory standard. PCIe Gen 5 support gives Intel a newer interconnect standard, though with fewer lanes (16 versus 20). The 125 W TDP and desktop socket 1700 position it for stationary, high-throughput systems.

The AMD Ryzen Embedded 8645HS wins on process technology and power efficiency on paper. The 4 nm node at TSMC, with 25,000 million transistors on a 178 mm² die, indicates a denser, likely more power-efficient design. The 45 W TDP is substantially lower than Intel's 125 W TDP, making it suited for mobile or thermally constrained embedded environments. The Radeon 760M integrated graphics may offer different GPU capabilities than Intel's UHD Graphics 770, though no benchmark data compares them.

For mobile applications, the AMD part's Socket FP8 and mobile market segment fit portable or compact designs. For desktop applications requiring maximum measured throughput, the Intel part's full benchmark suite and 93rd percentile ranking make it the data-supported choice.
