AMD Ryzen 5 3400GE vs Intel Atom C5125 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD Ryzen 5 3400GE across all six Cinebench comparisons, though the margins are consistently narrow. The most significant advantage appears in the multicore tests, where the Ryzen 5 3400GE posts a 757 score in Cinebench R15 multicore against the Intel Atom C5125's 739, a 2.4% delta. The gap widens slightly to 2.5% in the Cinebench R20 multicore test, with scores of 3158 and 3081 respectively. The Cinebench R23 multicore run follows the same pattern: 7520 for the AMD part versus 7336 for the Intel chip, again a 2.5% delta.

Single-core results tell a similar story, though the absolute differences are smaller in point terms. The Ryzen 5 3400GE leads 106 to 104 in Cinebench R15 single-core, a 1.9% delta. In Cinebench R20 single-core, the AMD processor scores 445 against 434, a 2.5% delta. The Cinebench R23 single-core test shows 1061 for the Ryzen part and 1035 for the Atom, maintaining that consistent 2.5% delta. Across all six benchmarks, the AMD Ryzen 5 3400GE wins every comparison, and the database records zero wins for the Intel Atom C5125.

The average benchmark score puts the Ryzen 5 3400GE at 2175, which places it in the 47th percentile of all CPUs in the database. The Intel Atom C5125 averages 2122, sitting in the 46th percentile. The nearest rivals for the AMD chip include the Intel Core i5-1145G7E at an average score of 2174 (a 0.1% delta), the Intel Core i7-1185GRE at 2178 (a negative 0.1% delta), and the Intel Core i5-7640X at 2167 (0.4% delta). For the Intel Atom, the closest competitors are the Intel Core i7-1160G7 at 2124 (negative 0.1% delta), the AMD Ryzen 5 7520C at 2127 (negative 0.2% delta), and the Intel Xeon E-2224G at 2117 (0.2% delta). These rival comparisons confirm that both processors occupy a similar performance tier, with the AMD part holding a slight but consistent edge.

Architecture Differences

The architectural divide between these two processors is substantial, reflecting their different design goals. The AMD Ryzen 5 3400GE belongs to the 3000 series, built on the Zen+ architecture with the Picasso codename. It uses a 12 nm process node manufactured by GlobalFoundries, with 4,940 million transistors on a 210 mm² die. The Intel Atom C5125, by contrast, belongs to the Atom family with the Parker Ridge codename, built on the Tremont generation architecture. It uses a 10 nm process node from Intel, though the database does not record transistor count or die size for this part.

Core configurations differ markedly. The Ryzen 5 3400GE offers 4 cores and 8 threads, enabling simultaneous multithreading. The Atom C5125 provides 8 physical cores but only 8 threads, meaning no hyperthreading support. Despite having twice the physical core count, the Atom cannot match the Ryzen's threaded performance in these tests, which indicates the Zen+ cores deliver significantly more per-thread throughput than the Tremont cores. Clock speeds reinforce this: the Ryzen 5 3400GE has a base clock of 3.30 GHz and a boost clock of 4.00 GHz, while the Atom C5125 runs at a fixed 2.80 GHz base clock with no boost clock recorded.

Cache hierarchies also diverge. The Ryzen 5 3400GE features 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Atom C5125 has a smaller L1 cache at 64 KB per core but a much larger L2 cache at 4.5 MB per module, with no L3 cache recorded. This cache design reflects the Atom's intended role in low-power, high-density server environments where per-core resources are allocated differently.

Power and platform characteristics separate these parts further. The Ryzen 5 3400GE has a 35 W TDP and uses AMD Socket AM4. The Atom C5125 has a 50 W TDP and uses Intel BGA 2106, a soldered embedded socket. Both support DDR4 memory with dual-channel buses and identical 46.9 GB/s memory bandwidth. The Ryzen part does not support ECC memory, while the Atom C5125 does support ECC. Both use PCIe Gen 3, with the Atom specifying 16 lanes for CPU only. The Ryzen 5 3400GE includes integrated Radeon RX Vega 11 graphics, while the Atom C5125 has no integrated graphics. The AMD chip has an unlocked multiplier, whereas the Intel part is locked. The Ryzen 5 3400GE launched in 2019, while the Atom C5125 launched in 2022.

Where Each One Wins

The benchmark data shows the AMD Ryzen 5 3400GE winning all six comparisons, but the practical use-case split requires looking beyond raw scores. The Ryzen 5 3400GE's advantage in both single-core and multicore Cinebench tests makes it the better choice for general-purpose desktop workloads, including everyday productivity, web browsing, and lightly threaded applications. Its 4 cores with 8 threads and boost clock up to 4.00 GHz provide responsive single-thread performance, which the 1.9% to 2.5% deltas over the Atom confirm. The integrated Radeon RX Vega 11 graphics also make the Ryzen part a self-contained desktop solution, eliminating the need for a discrete GPU in basic systems.

The Intel Atom C5125, despite losing all benchmark comparisons, has structural advantages that the data supports for specific environments. Its 8 physical cores, while slower per thread, provide more parallel hardware for workloads that scale across many independent tasks. The ECC memory support makes it suitable for error-sensitive data processing. The 10 nm process node and server/workstation market segment indicate a design focused on density and reliability rather than peak performance. The fixed 2.80 GHz clock with no boost behavior suggests predictable, consistent operation under sustained load, which can be valuable in always-on server roles. The BGA 2106 socket, while not upgradeable, suits embedded and appliance-style deployments.

The database records the Atom C5125's market segment as Server/Workstation, while the Ryzen 5 3400GE is marked Desktop. This classification aligns with the performance data: the Ryzen chip wins every benchmark, making it the superior choice for interactive and latency-sensitive tasks, while the Atom's value proposition rests on its core count, ECC support, and embedded form factor rather than benchmark dominance.

The Verdict

The recorded data is unambiguous: the AMD Ryzen 5 3400GE outperforms the Intel Atom C5125 in every single benchmark comparison, with deltas ranging from 1.9% in Cinebench R15 single-core to 2.5% across multiple other tests. The average benchmark score difference of 53 points (2175 versus 2122) and the percentile gap of 47 versus 46 reinforce this conclusion. Anyone selecting a processor purely on Cinebench performance should choose the Ryzen 5 3400GE.

However, the data also supports a differentiated recommendation based on use case. The Ryzen 5 3400GE is the clear choice for desktop systems, general computing, and any workload where single-thread responsiveness and integrated graphics matter. Its 35 W TDP, unlocked multiplier, and AM4 socket make it a flexible, efficient desktop processor. The Atom C5125, despite losing every benchmark, offers 8 cores, ECC memory support, and a server/workstation market segment designation. For embedded or server applications where data integrity through ECC is critical and where the 2.80 GHz fixed clock provides predictable operation, the Atom C5125 remains a viable option. The database shows no benchmark scenario where the Atom wins, so any selection of the Intel part must be justified by its platform features rather than its Cinebench scores. The launch MSRP for the Atom C5125 is $335, stated once here for reference.
