CPU Comparison

The Intel Core i5-10200H and Intel Atom C5125 occupy very different corners of the Intel lineup, yet the benchmark data places them in a surprisingly close overall contest. The i5-10200H is a mobile Comet Lake-H processor, while the C5125 is a server/workstation part from the Parker Ridge family. The head-to-head results show a clean sweep for the Atom part, which wins all six shared benchmark comparisons, but the margins are consistently narrow, hovering around 7% in favor of the C5125.

Head-to-Head Benchmarks

The data shows the Intel Atom C5125 winning every single benchmark in the comparison set, though by a modest and remarkably consistent margin. In Cinebench R15 multicore, the C5125 scores 739 against the i5-10200H's 684, a difference of -7.4% from the perspective of the i5. The single-core R15 test shows a similar story: 104 for the Atom versus 96 for the i5, a delta of -7.7%. This pattern holds across the newer Cinebench versions as well. In R20 multicore, the C5125 posts 3081 while the i5-10200H manages 2853, again a -7.4% gap. The R20 single-core results are 434 versus 402, maintaining that same -7.4% margin.

The trend continues into R23, where the multicore scores are 7336 for the Atom and 6795 for the i5, and the single-core scores are 1035 versus 959. The delta in both R23 tests is -7.4% and -7.3%, respectively. What is notable here is the consistency of the performance gap. Across six different workloads, the winning margin for the Atom C5125 never deviates far from roughly 7.3% to 7.7%. This suggests a fundamental throughput advantage rather than a workload-specific quirk.

The i5-10200H can claim no victories in this direct comparison. However, its average benchmark score of 2154 is actually slightly higher than the Atom's 2122 average across all recorded benchmarks in the database. This discrepancy arises because the i5 has Geekbench results included in its average (4096 multicore and 1347 single-core), while the Atom lacks Geekbench data in its profile. The percentile rankings are nearly identical, with the i5 at the 47th percentile of all CPUs and the Atom at the 46th, meaning both sit squarely in the middle of the performance distribution.

Where Each One Wins

The benchmark results indicate that the Intel Atom C5125 wins in every scenario where the two are directly compared. This includes both multicore and single-core workloads across three different Cinebench versions. The consistent 7% advantage suggests the C5125 is the stronger processor for rendering tasks, whether they are multi-threaded or single-threaded. Its eight physical cores, running at a base clock of 2.80 GHz, appear to provide a solid foundation for compute-heavy server workloads.

The Intel Core i5-10200H, despite its losses in the head-to-head tests, has its own favorable positioning. Its average benchmark score of 2154 places it marginally ahead of the Atom's 2122, and its percentile ranking of 47 is slightly better than the Atom's 46. The i5 also includes integrated UHD Graphics, which the Atom completely lacks. For any workload requiring graphical output or GPU acceleration without a discrete card, the i5 is the only viable option of the two. The i5's 45 W TDP is also lower than the Atom's 50 W, which could matter in thermally constrained mobile chassis.

Where the database shows no direct comparison, the i5's Geekbench scores (4096 multicore, 1347 single-core) suggest reasonable general-purpose performance that is not captured in the Cinebench-only head-to-head set. The Atom's profile lacks Geekbench data entirely, so a full picture of its general compute performance remains incomplete.

Architecture Differences

The two processors are built on fundamentally different Intel architectures. The Core i5-10200H uses the Comet Lake architecture on a 14 nm process node, with the codename Comet Lake-H. It has 4 cores and 8 threads, enabled by Hyper-Threading. The Atom C5125, by contrast, uses the Tremont architecture on a 10 nm node, under the Parker Ridge codename. It has 8 physical cores but only 8 threads, meaning no simultaneous multithreading.

Cache configurations differ significantly. The i5-10200H has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. The Atom C5125 also has 64 KB of L1 per core, but its L2 is organized differently: 4.5 MB per module, with no L3 cache listed. This organizational difference reflects the distinct design goals of a high-clock mobile part versus a low-power server part.

Memory support also diverges. The i5 supports both DDR3 and DDR4 memory, while the Atom supports only DDR4. Both run dual-channel memory with identical theoretical bandwidth of 46.9 GB/s. The Atom supports ECC memory, a critical feature for server reliability, while the i5 does not. PCIe support is Gen 3 for both, but the Atom specifies 16 lanes from the CPU only, whereas the i5's PCIe lane count is not detailed in the data. The i5 includes integrated UHD Graphics, while the Atom has no integrated graphics at all.

Clock speeds tell another part of the story. The i5 has a base clock of 2.40 GHz and a boost clock of 4.10 GHz, giving it substantial single-core headroom when thermal conditions allow. The Atom has a higher base clock of 2.80 GHz but no boost clock listed, suggesting it operates at a fixed frequency. This explains why the Atom can edge out the i5 in single-core Cinebench tests despite lacking a turbo mechanism.

Specification Differences

The two processors differ across nearly every core specification. The i5-10200H has 4 cores and 8 threads, while the Atom C5125 has 8 cores and 8 threads. Base clocks are 2.40 GHz for the i5 and 2.80 GHz for the Atom, but the i5 adds a 4.10 GHz boost clock while the Atom has no boost clock listed. TDP differs by 5 W, with the i5 at 45 W and the Atom at 50 W.

The socket is different: the i5 uses Intel BGA 1440, while the Atom uses Intel BGA 2106. The architecture differs, with the i5 on Comet Lake and the Atom on Tremont (Parker Ridge codename). Process nodes are 14 nm for the i5 and 10 nm for the Atom. L2 cache is 256 KB per core for the i5 versus 4.5 MB per module for the Atom, and the i5 has 6 MB of shared L3 cache while the Atom has no L3 listed.

The part numbers are SRK3X for the i5 and SRL40 for the Atom.

The Verdict

The data presents a clear picture: the Intel Atom C5125 outperforms the Intel Core i5-10200H in every benchmark where they are directly compared. Its 8-core configuration and higher base clock deliver a consistent ~7% advantage across Cinebench R15, R20, and R23, in both single-core and multicore tests. For pure computational throughput, the Atom C5125 is the stronger processor, and its ECC memory support and server/workstation market segment make it the appropriate choice for reliability-focused deployments.

However, the i5-10200H is not without its own rationale. It offers integrated graphics, which the Atom completely lacks, making it a functional solution for systems without a discrete GPU. Its lower TDP of 45 W versus 50 W could be advantageous in power-sensitive mobile designs. Its average benchmark score of 2154 is slightly above the Atom's 2122, and its 47th percentile ranking edges out the Atom's 46th, indicating that in the broader benchmark database, the i5 holds a marginal overall edge.

The choice between these two depends entirely on the use case. For a server or workstation where ECC memory, high core count, and raw Cinebench performance are priorities, the Atom C5125 is the data-backed winner. For a mobile system requiring integrated graphics and a lower thermal envelope, the i5-10200H is the only sensible option. The benchmark results show a narrow but decisive win for the Atom in raw compute, but the i5's feature set covers capabilities the Atom simply does not offer.
