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

Where Each One Wins

The AMD Ryzen Embedded 8840U and the Intel Core 9 273PQE occupy different performance tiers entirely. The Intel part holds a decisive advantage across every recorded benchmark in the database. The Core 9 273PQE records a 93rd percentile ranking against all CPUs, while the Ryzen Embedded 8840U sits at the 50th percentile. That 43-point percentile gap frames the entire comparison: the Intel chip is built for sustained high-throughput workloads, whereas the AMD part targets efficiency and embedded deployment.

The Intel Core 9 273PQE wins in every measurable category, but the margin varies by workload type. Its largest relative victories appear in multi-threaded rendering tests. In Cinebench R23 multi-core, it scores 39190, and in Cinebench R20 multi-core it records 16459. These are the kinds of results that indicate a processor capable of heavy parallel number crunching. The AMD part has no recorded benchmark scores in the database, so the comparison relies entirely on the Intel chip's measured results against its own rival set, not a direct head-to-head with the 8840U.

The AMD Ryzen Embedded 8840U still holds a clear positioning advantage in its intended segment: mobile embedded systems. Its 28 TDP classifies it as a low-power part, and its 4 nm process node from TSMC gives it a manufacturing density advantage. The Intel chip carries a 125 TDP, which places it in a much higher power envelope. For workloads where thermal headroom and energy draw matter more than raw throughput, the AMD processor's profile is the practical choice. The recorded data does not include any benchmark wins for the AMD part, but its architectural traits point to a different optimization target: efficiency over peak performance.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 8840U uses the Zen 4 architecture on the Hawk Point codename, built on a 4 nm process at TSMC. It integrates 25,000 million transistors on a 178 mm² die. The Intel Core 9 273PQE uses the Bartlett Lake codename on a 10 nm process at Intel's own foundry. The database lists no transistor count or die size for the Intel part.

Core counts differ substantially. The AMD chip provides 8 cores and 16 threads. The Intel chip provides 12 cores and 24 threads, a 50% advantage in both core and thread counts. Cache hierarchies also diverge. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Intel L3 cache is more than double the AMD allocation, which helps explain its strong multi-threaded performance.

Memory support splits as well. The AMD 8840U supports DDR5 only, while the Intel 273PQE supports both DDR4 and DDR5. Both run dual-channel memory with an identical 89.6 GB/s bandwidth figure. Both support ECC memory, which matters for embedded and workstation reliability. PCIe connectivity differs by generation: the AMD part provides Gen 4 with 20 CPU lanes, while the Intel part provides Gen 5 with 16 CPU lanes. Gen 5 doubles the per-lane bandwidth of Gen 4, so even with fewer lanes, the Intel platform offers higher total I/O throughput.

Integrated graphics also differ. The AMD chip carries a Radeon 780M, while the Intel chip uses UHD Graphics 770. The database does not include benchmark scores for either iGPU, so any comparison must stay qualitative. The Radeon 780M is the more capable integrated solution for general graphics tasks, though the Intel part targets systems where a discrete GPU is expected.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Ryzen Embedded 8840U and the Intel Core 9 273PQE. The AMD part has an empty benchmarks array, so no comparison of their raw scores is possible. What the database does provide is a full benchmark suite for the Intel chip, plus a set of nearest rivals with average scores and delta percentages.

The Intel Core 9 273PQE averages 66099 across its benchmark suite. Its closest rival is the Intel Core Ultra 5 250KF Plus with an average score of 66159, a delta of -0.1%, meaning the 273PQE trails that chip by one tenth of one percent. Against the AMD Ryzen 9 7950X3D, the 273PQE leads by 0.3%, with the rival averaging 65914. The gap to the Intel Core Ultra 5 250K Plus is -1.1%, and the AMD EPYC 4465P sits -1.2% behind the 273PQE at 66925. These deltas are tiny, all within 1.2 percentage points, which indicates the 273PQE lands in a tight cluster of high-end desktop and workstation processors.

Individual benchmark results for the Intel part show where its strengths concentrate. In Cinebench R23 multi-core it scores 39190, and in R20 multi-core 16459. The R15 multi-core result is 3950. Single-core scores scale similarly: R23 single-core 5532, R20 single-core 2323, R15 single-core 557. PassMark results reinforce the multi-threaded profile: multithread score 46107, integer math 164629, floating point math 125546, extended instructions 38743, data compression 585752, data encryption 29636, random string sorting 53167, physics 2754, find prime numbers 198, and single-thread 4573.

The single-thread to multi-thread ratio tells a clear story. The R23 multi-core score is roughly seven times the single-core score, which aligns with the 12-core, 24-thread configuration. The PassMark multithread score of 46107 versus a single-thread score of 4573 shows similar scaling. This is a processor built for parallel workloads that can consume 24 threads simultaneously.

Specification Differences

The database lists several specification fields where the two processors diverge. The AMD Ryzen Embedded 8840U belongs to the 8000 series and uses an AMD Socket FP8. The Intel Core 9 273PQE uses Intel Socket 1700. The AMD part has a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The Intel part has a base clock of 3.40 GHz and a boost clock of 5.90 GHz. The Intel chip runs 0.10 GHz higher at base and 0.80 GHz higher at boost.

Power draw differs dramatically. The AMD part has a 28 TDP. The Intel part has a 125 TDP. That is a 97-point gap, which makes the Intel chip suitable only for platforms with robust cooling and power delivery. The AMD chip fits into fanless or low-profile embedded designs.

The process node gap is equally stark. The AMD part uses a 4 nm process from TSMC. The Intel part uses a 10 nm process from Intel. The AMD chip integrates 25,000 million transistors on a 178 mm² die. The Intel chip has no transistor or die size data in the database. The AMD part also has a different cache structure per core: 64 KB L1 and 1 MB L2, versus the Intel part's 80 KB L1 and 2 MB L2. Shared L3 is 16 MB on AMD and 36 MB on Intel.

Memory support differs: the AMD part is DDR5-only, while the Intel part accepts both DDR4 and DDR5. Both have dual-channel memory buses and identical 89.6 GB/s bandwidth. PCIe generation sets them apart: AMD provides Gen 4 with 20 CPU lanes; Intel provides Gen 5 with 16 CPU lanes. Integrated graphics differ: Radeon 780M on AMD, UHD Graphics 770 on Intel.

Market segment and release date also differ. The AMD part targets mobile, released in 2024. The Intel part targets desktop, released in 2026. The Intel part carries a launch MSRP of $589. The AMD part has no launch MSRP listed. The Intel part has a part number of SA4Q9; the AMD part's part number is unknown. Neither processor has an unlocked multiplier.

The Intel chip has a production status of Active, as does the AMD chip. Both support ECC memory. Both are currently in production.
