AMD Ryzen Embedded 8840U vs Intel Core 3 305 Comparison

Where Each One Wins

The data shows a clear split between the two processors based on workload type. The AMD Ryzen Embedded 8840U wins in every recorded benchmark category where both have comparable data, but the Intel Core 3 305 has a substantial advantage in overall CPU percentile ranking. The Intel part sits at the 72nd percentile against all CPUs, while the AMD part is at the 50th percentile. This is a notable gap, but the absence of benchmark data for the AMD processor in the database means the percentile comparison reflects only the Intel side's measured results.

The Intel Core 3 305 shows its strength in multi-threaded synthetic workloads. Its Cinebench R23 multi-core score of 13,123 points places it in a competitive position for productivity tasks. The single-core Cinebench R23 result of 1,852 points indicates solid per-thread performance. In PassMark tests, the Intel part delivers a multi-thread score of 15,439 and a single-thread score of 3,977, which are the only recorded scores available for either processor.

The AMD Ryzen Embedded 8840U has no recorded benchmark scores in the database. Its wins must be assessed from architectural specifications rather than measured results. The processor uses 8 cores and 16 threads, which is double the thread count of the Intel Core 3 305. The base clock of 3.30 GHz and boost clock of 5.10 GHz are both higher than the Intel part's 1.50 GHz base and 4.30 GHz boost. These specifications suggest the AMD processor would lead in heavily threaded workloads, but no benchmark numbers confirm this in the database.

The Intel Core 3 305 wins in the only directly comparable recorded metric: the average benchmark score. Its average is 18,302, and its nearest rival, the Intel Core i3-14100, scores 18,318, a delta of -0.1%. The AMD processor has an average benchmark score of zero because no benchmarks are recorded for it.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 8840U uses Zen 4 architecture under the Hawk Point codename, manufactured on a 4 nm process at TSMC. The Intel Core 3 305 uses the Wildcat Lake codename, manufactured on a 3 nm process at Intel. The AMD part integrates 25,000 million transistors on a 178 mm² die, while the Intel part has no transistor count or die size recorded.

Cache configurations differ substantially. The AMD processor provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor provides 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD design allocates more cache per core and offers a larger total L3 pool, which typically benefits data-heavy workloads.

Memory support also diverges. The AMD part supports DDR5 memory on a dual-channel bus with 89.6 GB/s of memory bandwidth and includes ECC memory support. The Intel part supports DDR5 and LPDDR5X memory on a single-channel bus with 59.7 GB/s of memory bandwidth and does not support ECC memory. The single-channel configuration halves the memory path width compared to the dual-channel AMD design, and the bandwidth difference is roughly 50% in favor of the AMD processor.

PCIe connectivity differs as well. The AMD processor offers Gen 4 with 20 CPU lanes, while the Intel processor offers Gen 4 with only 6 CPU lanes. This is a significant expansion difference for systems that need to attach multiple NVMe drives, accelerators, or other PCIe peripherals.

Integrated graphics differ by vendor and generation. The AMD processor uses the Radeon 780M, while the Intel processor uses Intel Xe3 Graphics with 1 Xe core. The database records no benchmark scores for either integrated GPU, so no performance comparison is possible from the data.

Power characteristics differ. The AMD processor has a TDP of 28 watts, while the Intel processor has a TDP of 15 watts. The Intel part consumes less power on paper, but the AMD part offers higher clock speeds and more cores within its higher power envelope.

The Verdict

The data supports a conditional choice based on workload requirements. The Intel Core 3 305 has recorded benchmark results and a 72nd percentile ranking against all CPUs, making it the only processor in this comparison with measured performance data. Its nearest rivals in the database include the Intel Core i3-14100 at a 0.1% lower average score, the Intel Core 5 330 at 0.2% lower, the Intel Core 7 360 at 0.4% lower, and the AMD Ryzen 5 2600E at 0.4% higher. These tight deltas indicate the Intel Core 3 305 sits in a dense performance cluster.

The AMD Ryzen Embedded 8840U cannot be verified through benchmark data. Its architectural specifications indicate a higher core count, higher clocks, larger cache, dual-channel memory, ECC support, and more PCIe lanes. These are meaningful advantages for server or embedded workloads that require parallel execution, memory bandwidth, or error-correcting memory.

The verdict from the recorded data is that the Intel Core 3 305 is the only part with demonstrated performance in the database, and its 15-watt TDP makes it suitable for power-sensitive mobile designs. The AMD part offers a broader feature set on paper, but the absence of measured scores prevents a data-backed performance verdict. Systems requiring ECC memory, dual-channel bandwidth, or more than 6 PCIe lanes would need the AMD processor, but no benchmark evidence in the database supports a raw speed claim for it.
