AMD Ryzen Embedded 8840U vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The recorded data shows no benchmark scores for either processor in this comparison. Both the AMD Ryzen Embedded 8840U and the Intel Core 7 251E have zero entries in the benchmark database, with an average benchmark score of 0 for each. Consequently, there are no head-to-head benchmark results to analyze, no wins recorded for either part (0 wins for AMD, 0 wins for Intel), and no performance deltas to report.

Both processors sit at the 50th percentile against all CPUs in the database, a neutral position that reflects the absence of measured performance data rather than any actual performance parity. Without benchmark scores, the database cannot confirm which part delivers superior single-threaded, multi-threaded, or integrated graphics performance. The lack of nearest rivals data for either processor further limits any comparative analysis based on measured results.

What the data does allow is a structural comparison. The Intel Core 7 251E provides 24 cores and 32 threads, while the AMD Ryzen Embedded 8840U provides 8 cores and 16 threads. The Intel part shows a higher boost clock at 5.60 GHz versus 5.10 GHz for the AMD part, though the AMD part has a higher base clock at 3.30 GHz versus 2.10 GHz for Intel. The Intel processor carries a larger shared L3 cache of 36 MB versus 16 MB for the AMD processor, and a larger per-core L2 cache (2 MB per core versus 1 MB per core) and per-core L1 cache (80 KB per core versus 64 KB per core). These specification differences suggest the Intel part is positioned for higher multi-threaded workloads, while the AMD part emphasizes higher base frequency and efficiency, but the lack of benchmark data means these structural advantages cannot be quantified in performance terms.

The database records no head-to-head benchmark entries for this pairing. Any claims about relative performance would require measured data that is not present in the current records.

Architecture Differences

The AMD Ryzen Embedded 8840U uses the Zen 4 architecture with the Hawk Point codename, part of the 8000 series. It is fabricated on a 4 nm process node at TSMC, with 25,000 million transistors and a die size of 178 mm². The Intel Core 7 251E uses the Bartlett Lake codename, part of the Core 7 generation, fabricated on a 10 nm process node at Intel with a die size of 257 mm². The Intel part has no transistor count listed in the database.

The Intel processor uses Intel Socket 1700, while the AMD processor uses AMD Socket FP8. The Intel part is classified as a desktop market segment processor, whereas the AMD part is classified as mobile. The Intel part supports PCIe Gen 5 with 16 lanes (CPU only), while the AMD part supports PCIe Gen 4 with 20 lanes (CPU only).

The integrated graphics differ substantially. The AMD Ryzen Embedded 8840U integrates a Radeon 780M, while the Intel Core 7 251E integrates UHD Graphics 770. No benchmark data exists for either integrated GPU, so relative graphics performance cannot be quantified.

The Intel part has a part number listed (SRQDUQ657), while the AMD part has an unknown part number. Neither processor has an unlocked multiplier, meaning both are locked for overclocking.

The Intel Core 7 251E has a launch MSRP of $384.

The Verdict

The data presents two processors with fundamentally different design targets. The AMD Ryzen Embedded 8840U is a mobile processor with 8 cores, 16 threads, a 28 TDP, and a 4 nm process node from TSMC. The Intel Core 7 251E is a desktop processor with 24 cores, 32 threads, a 65 TDP, and a 10 nm process node from Intel.

For multi-threaded workloads, the Intel Core 7 251E has a clear structural advantage: triple the core count, double the thread count, a larger L3 cache (36 MB versus 16 MB), and larger per-core caches. The Intel part also has a higher boost clock (5.60 GHz versus 5.10 GHz), which could benefit lightly threaded tasks that reach maximum frequency.

For efficiency and base frequency, the AMD Ryzen Embedded 8840U holds advantages. Its 28 TDP is less than half of the Intel part's 65 TDP, its base clock of 3.30 GHz is substantially higher than Intel's 2.10 GHz, and its 4 nm process node from TSMC represents a more advanced fabrication process than Intel's 10 nm node. The AMD part also provides more PCIe lanes (20 versus 16), albeit on Gen 4 versus Gen 5.

The market segment classification reinforces this split: the AMD part is built for mobile platforms on Socket FP8, while the Intel part targets desktop platforms on Socket 1700. The Intel part supports both DDR4 and DDR5 memory, while the AMD part supports DDR5 only, which may matter for platform flexibility.

Both processors support ECC memory, making both suitable for embedded or workstation applications where data integrity is critical. Both are locked processors with no unlocked multiplier.

The database contains no benchmark scores for either processor, so a performance verdict cannot be derived from measured results. The structural data indicates that the Intel Core 7 251E should be selected for workloads that scale with core count and thread count, given its 24 cores, 32 threads, and larger caches. The AMD Ryzen Embedded 8840U should be selected for power-constrained mobile or embedded applications, given its 28 TDP, higher base clock, and more advanced 4 nm process node. The Intel part carries a launch MSRP of $384, while the AMD part has no listed launch MSRP.

Without benchmark data, the percentile ranking of 50 for both processors carries no meaningful comparative weight. The final selection between these two parts depends entirely on the platform requirements (mobile versus desktop), the power envelope, and the expected workload characteristics, all of which are clearly differentiated in the specification records.
