AMD Ryzen Embedded 8840U vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The recorded data set for this comparison is asymmetric. The AMD Ryzen Embedded 8840U carries no benchmark entries in the database, which means no direct head-to-head test scores exist between these two processors. The Intel Core 9 273PE, by contrast, has a full suite of 17 recorded benchmark results across Cinebench and Passmark tests.

The Intel Core 9 273PE posts an average benchmark score of 49845, placing it at the 90th percentile among all CPUs in the database. Its nearest rivals in the aggregate rankings include the AMD Ryzen AI Max+ 388 with an average score of 49796, which is 0.1% behind, and the Intel Core i5-14600KF at 49394, which trails by 0.9%. On the upper side, the Intel Core i9-13980HX scores 50398, putting it 1.1% ahead of the Core 9 273PE, and the AMD Ryzen AI 9 HX PRO 370 reaches 50448, 1.2% higher.

Within the Intel Core 9 273PE's own benchmark results, the multicore performance is substantial. The Cinebench R23 multicore test records a score of 31288, while the R20 multicore result is 13140 and the R15 multicore result is 3153. Single-core results are 4417 in R23, 1855 in R20, and 445 in R15. Passmark tests show a multithread score of 36810 and a single-thread score of 3650. The integer math test reaches 139410, floating point math hits 107884, and data compression scores 405885. Data encryption records 22719, extended instructions reach 24630, and random string sorting posts 45098. The find prime numbers test scores 203, and the physics test records 3120.

Because the AMD part has no benchmark scores recorded, the database cannot produce a head-to-head win count. The winsA and winsB fields are both zero, reflecting the absence of shared test data rather than a tie in performance.

Architecture Differences

The two processors come from different design philosophies and manufacturing backgrounds. The AMD Ryzen Embedded 8840U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It packs 25,000 million transistors onto a 178 mm² die. The Intel Core 9 273PE uses the Bartlett Lake codename under the Core 9 generation label, built on a 10 nm process at Intel. No transistor count or die size is recorded for the Intel part.

Core configurations differ sharply. The AMD part provides 8 cores and 16 threads, while the Intel part provides 12 cores and 24 threads. Base clocks are 3.30 GHz for AMD and 2.30 GHz for Intel, but the boost clocks reverse the order: 5.10 GHz for AMD and 5.70 GHz for Intel. The TDP ratings also diverge, with the AMD chip rated at 28 watts and the Intel chip at 65 watts.

Cache hierarchies are structured differently. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. Neither part lists a 3D V-Cache option.

Memory support shows a generation gap. The AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. Both use a dual-channel memory bus, and both record the same memory bandwidth figure of 89.6 GB/s. Both support ECC memory.

PCIe capabilities differ in generation and lane count. The AMD part provides Gen 4 with 20 CPU-only lanes, while the Intel part provides Gen 5 with 16 CPU-only lanes. Integrated graphics also differ: the AMD chip uses the Radeon 780M, while the Intel chip uses UHD Graphics 730.

The market segments are different as well. The AMD part is classified as a mobile processor and uses AMD Socket FP8. The Intel part is classified as a desktop processor and uses Intel Socket 1700. The AMD part was released on 2024-04-01, while the Intel part has a release date of 2026-03-08. Both are listed as active in production, and neither has an unlocked multiplier.

The Verdict

The data supports a clear division of roles. The Intel Core 9 273PE is the only one of the two with recorded benchmark results, and those results are strong. Its 90th percentile ranking places it above the majority of CPUs in the database, and its aggregate score of 49845 sits within 1.2% of the AMD Ryzen AI 9 HX PRO 370 and 1.1% of the Intel Core i9-13980HX. For workloads that stress multicore throughput, the Intel part's 12 cores, 24 threads, and 36 MB of L3 cache provide a structural advantage, and the recorded Cinebench R23 multicore score of 31288 reflects that capacity.

The AMD Ryzen Embedded 8840U cannot be evaluated on benchmark performance because the database contains no scores for it. What can be assessed is its configuration. The 8-core, 16-thread Zen 4 design on a 4 nm TSMC process with a 28 watt TDP indicates a focus on efficiency and mobility. Its 5.10 GHz boost clock is lower than the Intel part's 5.70 GHz, but its base clock of 3.30 GHz is higher. The Radeon 780M integrated graphics outclasses the UHD Graphics 730 on paper, which matters for systems that rely on the iGPU. The AMD part also uses a newer PCIe generation in Gen 4, though with more lanes at 20 versus the Intel part's 16 Gen 5 lanes.

The Intel part carries a recorded launch MSRP of $549. The AMD part has no launch MSRP recorded.

For systems where the CPU must deliver maximum multi-threaded throughput in a desktop context, the Intel Core 9 273PE is the only choice supported by benchmark evidence. For embedded or mobile deployments where power draw, process efficiency, and integrated graphics capability take priority, the AMD Ryzen Embedded 8840U presents a compelling configuration, though its actual performance remains unmeasured in the database.

Where Each One Wins

The Intel Core 9 273PE wins in every category where recorded benchmark data exists. Its 12 cores and 24 threads give it a structural edge in multi-threaded workloads, and the recorded Cinebench R23 multicore score of 31288 demonstrates that advantage in practice. The 36 MB L3 cache and 5.70 GHz boost clock support both multi-threaded and single-threaded performance, with the R23 single-core score of 4417 reflecting a strong single-thread capability. The desktop socket, Gen 5 PCIe with 16 lanes, and dual DDR4/DDR5 support make it suitable for systems that need current high-bandwidth I/O while retaining compatibility with older memory types. Its 90th percentile ranking places it above the overwhelming majority of CPUs in the database.

The AMD Ryzen Embedded 8840U wins in efficiency-oriented specifications. Its 28 watt TDP is less than half the Intel part's 65 watt rating, which matters for thermally constrained or power-sensitive deployments. The 4 nm TSMC process with 25,000 million transistors on a 178 mm² die indicates a denser, more modern manufacturing approach than the Intel part's 10 nm process. The Radeon 780M integrated graphics is a stronger iGPU solution on paper than the UHD Graphics 730, which benefits systems that rely on the built-in display output. The higher base clock of 3.30 GHz and 20 PCIe Gen 4 lanes provide additional configuration advantages. The mobile socket classification and 2024 release date position it as an earlier, lower-power option for embedded platforms where benchmark throughput is secondary to power envelope and integration.
