AMD Ryzen 5 5560U vs Intel Atom P5342 Comparison

Head-to-Head Benchmarks

The recorded data splits the benchmark wins evenly, with each processor taking two victories in the head-to-head tests. However, the margins of those wins tell a more complex story than the simple 2-2 tally suggests.

In Cinebench R15, the AMD Ryzen 5 5560U demonstrates clear superiority. In the multicore test, the AMD scores 1280 against the Intel Atom P5342's 1121, a delta of -12.4% from the Intel's perspective. The single-core test shows an even larger gap: AMD scores 202 versus Intel's 158, representing a -21.8% difference. These are substantial margins, particularly the single-core result, which indicates a significant per-thread performance advantage for the Zen 3 architecture.

The picture flips dramatically in Cinebench R23. Here, the Intel Atom P5342 takes decisive wins. In the multicore test, Intel scores 11122 against AMD's 7667, a massive 45.1% advantage. This is the largest margin in any head-to-head comparison between these two parts. The single-core R23 test also favors Intel, with a score of 1570 versus AMD's 1260, a 24.6% lead.

The contradiction between the R15 and R23 results is striking. In one benchmark generation, AMD wins both tests convincingly; in the next, Intel wins both by even larger margins. This suggests that the two processors have very different performance scaling characteristics depending on the workload and benchmark version. The R23 multicore result, in particular, highlights the Intel Atom P5342's ability to leverage its 16 cores effectively under sustained multi-threaded load, while the R15 results suggest AMD's 6 cores with 12 threads are more efficient in shorter, lighter workloads.

Looking at the broader database context, both processors sit at the 53rd percentile among all CPUs, indicating they occupy a similar overall performance tier despite their architectural differences. The Intel Atom P5342 has an average benchmark score of 3217, while the AMD Ryzen 5 5560U averages 3162. The nearest rivals for Intel include the AMD Ryzen 3 PRO 5350GE at 3218 (0% delta) and the AMD Ryzen 7 4800U at 3218 (0% delta), as well as the Intel Core i5-1240P at 3202 (0.5% delta) and the Intel Core i3-13100T at 3198 (0.6% delta). For AMD, the closest competitors are the Intel Xeon E5-2676 v3 at 3163 (0% delta), the AMD Ryzen 3 5300GE at 3160 (0.1% delta), the AMD Ryzen 7 PRO 5850U at 3159 (0.1% delta), and the Intel Xeon E5-2650 v4 at 3154 (0.3% delta).

Architecture Differences

The foundational architectures of these two processors could hardly be more different. The Intel Atom P5342 is built on the Snow Ridge platform, using the Atom (Tremont) generation architecture. It is fabricated on Intel's 10 nm process node at Intel's own foundry. The AMD Ryzen 5 5560U, by contrast, uses the Zen 3 architecture under the Cezanne-U codename, manufactured on TSMC's 7 nm process node. The AMD chip also carries a "5000 series" series designation, while the Intel part has no series designation in the database.

Core and thread counts represent the most obvious divergence. The Intel Atom P5342 packs 16 cores with 16 threads, meaning no simultaneous multithreading. The AMD Ryzen 5 5560U has 6 cores and 12 threads, leveraging simultaneous multithreading to double its thread count. This difference explains the R23 multicore result: Intel's 16 physical cores can sustain heavy parallel loads, while AMD's 6 cores rely on thread-level parallelism that does not scale as effectively in that benchmark.

Clock speeds also differ. The Intel Atom P5342 has a base clock of 2.20 GHz with no boost clock recorded. The AMD Ryzen 5 5560U has a base clock of 2.30 GHz and a boost clock of 4.00 GHz. The AMD's higher base clock and substantial boost capability account for its single-core dominance in R15, where frequency headroom matters greatly.

Cache hierarchies are structured differently as well. Both processors share the same L1 cache configuration at 64 KB per core. However, the L2 cache differs: Intel uses 4.5 MB per module, while AMD uses 512 KB per core. The AMD part also features 8 MB of shared L3 cache, while the Intel Atom P5342 has no L3 cache recorded in the database. This L3 presence likely contributes to AMD's efficiency in certain workload patterns.

Memory support shows both processors use DDR4 with dual-channel memory buses. The AMD Ryzen 5 5560U has a higher memory bandwidth at 51.2 GB/s compared to Intel's 42.7 GB/s. Both support ECC memory. PCIe connectivity differs: Intel offers Gen 3 with 16 lanes (CPU only), while AMD provides Gen 3 with 8 lanes (CPU only).

The AMD processor includes integrated Radeon Vega 6 graphics, while the Intel Atom P5342 has no integrated graphics. This is a significant feature gap for any use case requiring display output without a discrete GPU. The Intel part targets the Server/Workstation market segment, while AMD targets Mobile. Both processors have locked multipliers and are currently marked as Active in production status.

Transistor count and die size are recorded only for AMD: 10,700 million transistors on a 180 mm² die. No such figures exist for the Intel part in the database. The Intel Atom P5342 launched on 2022-06-05 with a launch MSRP of $708, while the AMD Ryzen 5 5560U launched earlier on 2021-01-11 with no launch MSRP recorded. The power envelope differs substantially: Intel's TDP is 71, while AMD's is 15, reflecting the mobile versus server/workstation positioning.

Where Each One Wins

The benchmark data points to clear use-case splits. The AMD Ryzen 5 5560U wins in scenarios that favor high single-thread performance and moderate multi-thread loads. Its R15 results, particularly the 21.8% single-core advantage, suggest it excels in responsive, latency-sensitive tasks such as interactive applications, light productivity work, and workloads that cannot effectively utilize more than a handful of threads. The 15 TDP also implies it can sustain these performance levels in thermally constrained environments, typical of mobile computing.

The Intel Atom P5342, conversely, demonstrates its strength in heavily parallel, sustained workloads. The R23 multicore result, a 45.1% lead over AMD, indicates that applications which scale across many cores will see significant benefit from the Intel part's 16 physical cores. This aligns with its Server/Workstation market segment, where workloads such as virtualization, container orchestration, or data processing often demand many concurrent threads. The 71 TDP reflects a willingness to consume more power for throughput, which is acceptable in server racks but problematic for battery-powered devices.

The R23 single-core result is curious: Intel wins by 24.6%, despite AMD having a higher boost clock. This suggests that the Intel Atom P5342's Tremont cores are more efficient in the R23 single-thread workload than the clock speed alone would predict, or that AMD's boost clock is not sustained under this particular test. This anomaly means users should not assume AMD wins all single-thread tests; the specific benchmark and workload matter greatly.

For mixed workloads, the average benchmark scores are nearly identical: 3217 for Intel versus 3162 for AMD, a difference of only 1.7%. This near-parity in the aggregate suggests that for general-purpose computing with varied tasks, either processor would deliver comparable overall performance, with the choice depending on workload composition rather than raw capability.

The Verdict

The data points to a clear division: the Intel Atom P5342 is the choice for heavily threaded, sustained workloads. Its 16 physical cores and 45.1% R23 multicore lead over AMD make it the stronger option for server or workstation deployments where parallel throughput is the primary goal. The 71 TDP and Server/Workstation market segment reinforce this positioning. However, the absence of integrated graphics means any system built around this processor must account for a discrete GPU, adding complexity and power draw.

The AMD Ryzen 5 5560U is better suited for mobile or thermally constrained environments. Its 15 TDP, integrated Radeon Vega 6 graphics, and 4.00 GHz boost clock make it a more self-contained solution for laptops or compact systems. The R15 results, with AMD winning both tests, suggest it handles everyday interactive workloads with greater responsiveness. The 21.8% single-core advantage in R15 indicates better per-thread performance for applications that are not highly parallel.

For users who prioritize raw multi-thread throughput in a server context, the Intel Atom P5342 is the data-backed recommendation. For users who need a balanced, efficient mobile processor with integrated graphics and strong single-thread capability, the AMD Ryzen 5 5560U is the clear choice. The near-identical average benchmark scores (3217 versus 3162) mean that neither processor is universally faster; the decision rests entirely on workload type and platform requirements.
