AMD Ryzen Embedded 8840U vs Intel Core 5 223PQE Comparison

Where Each One Wins

The database does not currently include benchmark results for either processor, so a direct performance comparison based on measured scores is not possible. What the recorded data does show is a clear split by market segment and intended use case. The AMD Ryzen Embedded 8840U is listed as a mobile processor, part of the Ryzen Embedded 8000 series, with a 28 W TDP. The Intel Core 5 223PQE is a desktop processor from the Bartlett Lake generation, with a 125 W TDP. These two figures alone indicate fundamentally different design targets: the AMD part is built for power-constrained embedded and mobile environments, while the Intel part is built for desktop systems where higher power delivery is acceptable.

The AMD processor uses an integrated Radeon 780M graphics solution, which is a substantial integrated GPU for a mobile-class part. The Intel processor uses UHD Graphics 770, a more conventional desktop integrated graphics solution. In cases where the workload relies heavily on the integrated GPU, the AMD part likely holds an advantage given the Radeon 780M's positioning in the database as a higher-tier integrated graphics option. For the Intel part, the integrated graphics are present but not the primary selling point of a desktop processor.

The Intel Core 5 223PQE has higher clock speeds in the recorded specifications. Its base clock is listed at 4.00 GHz versus 3.30 GHz for the AMD part, and its boost clock is 5.50 GHz versus 5.10 GHz. For single-threaded workloads that scale with clock frequency, the Intel processor has a theoretical advantage. The AMD processor, however, uses a 4 nm process node from TSMC, while the Intel part uses a 10 nm node from Intel's own foundry. The smaller process node gives the AMD part a density and efficiency advantage, which aligns with its lower TDP.

The absence of benchmark scores means the database cannot currently assign a win count to either processor. The wins in the head-to-head section are both zero, and the average benchmark score for each is zero. This is not a statement about performance; it is a reflection of missing measurement data. The percentile versus all CPUs is 50 for both, which is the default neutral value when no benchmark data has been recorded. Users should interpret these values as placeholders rather than performance rankings.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen Embedded 8840U uses the Zen 4 architecture under the Hawk Point codename. The Intel Core 5 223PQE uses the Bartlett Lake codename, and the database does not list a formal architecture name for it, only the generation label "Core 5 (Bartlett Lake)". The AMD part is built on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die. The Intel part has no transistor count or die size recorded, and its process node is listed as 10 nm with Intel as the foundry.

Cache organization differs between the two. The AMD processor has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Intel part therefore has more cache at every level, which can help with workloads that exhibit high cache reuse. The AMD part relies on a smaller total cache footprint but compensates with a more advanced process node and higher memory bandwidth per watt.

Both processors support dual-channel memory and have the same recorded memory bandwidth of 89.6 GB/s. The AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. This gives the Intel processor more flexibility in system design, as it can be paired with either memory generation. Both support ECC memory, which is important for embedded and reliability-focused applications.

PCIe support differs significantly. The AMD processor uses PCIe Gen 4 with 20 lanes from the CPU. The Intel processor uses PCIe Gen 5 with 16 lanes from the CPU. The Intel part has a newer PCIe standard, which doubles the per-lane bandwidth compared to Gen 4, but the AMD part offers more total lanes. For systems that need many lanes at moderate bandwidth, the AMD part has an advantage. For systems that need maximum bandwidth on a single device, such as a high-end GPU or NVMe drive, the Intel part has an advantage.

The socket types are entirely different. The AMD part uses AMD Socket FP8, which is a mobile and embedded socket. The Intel part uses Intel Socket 1700, which is a desktop socket with broad motherboard availability. Neither processor has an unlocked multiplier, so overclocking is not supported on either platform according to the recorded data.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. The wins for each side are zero, and the head-to-head benchmark array is empty. Without measured scores, there is no way to state which processor is faster in any specific workload category.

What can be analyzed from the recorded data is the theoretical positioning based on specifications. The Intel processor has a base clock that is 0.70 GHz higher than the AMD part, and a boost clock that is 0.40 GHz higher. In single-threaded workloads that are not limited by power or thermals, the Intel part should sustain higher frequencies. The AMD part, with a 28 W TDP, will hit power limits much sooner than the Intel part, which has a 125 W TDP. This means the Intel part can maintain higher clocks under sustained load, assuming adequate cooling.

The AMD part has a smaller process node, which typically translates to better performance per watt. In power-constrained scenarios, such as thin embedded systems or fanless designs, the AMD part can deliver more performance within its power envelope. The Intel part, with more headroom for power consumption, can push higher absolute performance in desktop systems that have sufficient cooling.

Memory support also plays a role. The Intel part supports both DDR4 and DDR5, so a system builder can choose a slower but cheaper memory configuration or a faster DDR5 configuration. The AMD part is locked to DDR5, which means higher memory performance is mandatory but also higher platform cost. Both parts have identical memory bandwidth in the database at 89.6 GB/s, so the memory subsystem is not a differentiator in raw bandwidth.

The integrated graphics are a clear differentiator. The Radeon 780M in the AMD part is a high-end integrated GPU in the database's classification. The UHD Graphics 770 in the Intel part is a more modest integrated solution. For systems that need to drive displays or handle light graphics workloads without a discrete GPU, the AMD part has a stronger integrated option.

Specification Differences

The two processors differ in several key specification fields. The AMD Ryzen Embedded 8840U has a base clock of 3.30 GHz, while the Intel Core 5 223PQE has a base clock of 4.00 GHz. The boost clocks are 5.10 GHz and 5.50 GHz respectively. The AMD part has a TDP of 28 W, while the Intel part has a TDP of 125 W.

The socket is different: AMD Socket FP8 for the AMD part, Intel Socket 1700 for the Intel part. The process node is 4 nm at TSMC for the AMD part, and 10 nm at Intel for the Intel part. The AMD part has 25,000 million transistors on a 178 mm² die; the Intel part has no recorded transistor count or die size.

Cache differs at every level. The AMD part has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel part has 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. Memory support is DDR5 only for the AMD part, and DDR4 plus DDR5 for the Intel part. Both support dual-channel memory and ECC.

PCIe is Gen 4 with 20 lanes for the AMD part, and Gen 5 with 16 lanes for the Intel part. The integrated graphics are Radeon 780M for the AMD part and UHD Graphics 770 for the Intel part. The market segment is mobile for the AMD part and desktop for the Intel part.

The Verdict

The data supports a clear split in use cases. The AMD Ryzen Embedded 8840U is the choice for power-constrained embedded and mobile systems. Its 28 W TDP, 4 nm process, and Radeon 780M integrated graphics make it suitable for compact designs where power efficiency and integrated graphics capability matter. The Intel Core 5 223PQE is the choice for desktop systems where power is less of a constraint. Its 125 W TDP, higher clock speeds, and larger cache give it a theoretical edge in sustained high-frequency workloads.

The Intel part also offers more platform flexibility with support for both DDR4 and DDR5 memory, and it has PCIe Gen 5 support for high-bandwidth devices. The AMD part offers more PCIe lanes and a smaller process node. Neither processor has an unlocked multiplier, so overclocking is not a factor.

The database currently lacks benchmark scores for both processors, so any performance conclusions are based on specification analysis alone. The percentile values of 50 for both are neutral placeholders and should not be read as performance rankings. Until benchmark data is recorded, the decision between these two processors should be driven by platform requirements: mobile and embedded power efficiency points to the AMD part, desktop performance and memory flexibility points to the Intel part.
