AMD Ryzen 7 PRO 5850U vs Intel Atom P5342 Comparison

The Intel Atom P5342 and the AMD Ryzen 7 PRO 5850U are two processors that land in the same overall performance band while serving entirely different design goals. Both sit at the 53rd percentile in the database, with average benchmark scores of 3217 and 3159 respectively, yet they arrive at nearly identical aggregate performance through opposite routes: the Atom uses many small, low-clock cores, while the Ryzen uses fewer, faster Zen 3 cores running at much higher frequencies. The recorded data shows a split result, with each chip winning two of the four head-to-head tests, and the pattern of those wins tells a clear story about which workloads favor which design.

The Verdict

The data points to a straightforward division. The Atom P5342 is the pick for sustained, thread-heavy server and workstation loads: it took the Cinebench R23 multi-core test with 11122 points against 8716, a 27.6 percent advantage, and it also leads in R23 single-core with 1570 against 1405, an 11.7 percent gap. It is a 16-core, 16-thread part with a 71 W TDP, ECC memory support, and 16 lanes of PCIe Gen 3 from the CPU, all of which align with its Server/Workstation market segment. Its launch MSRP was $708.

The Ryzen 7 PRO 5850U is the pick where per-cycle responsiveness and efficiency in a mobile platform matter most. It dominated the older Cinebench R15 tests, scoring 1467 versus 1121 in multi-core (23.6 percent ahead) and 227 versus 158 in single-core (30.4 percent ahead). It does all this within a 15 W TDP, it carries integrated Radeon Vega 8 graphics where the Atom has none, and it sits in a mobile socket (FP6) rather than a soldered server package. Its higher boost clock of 4.40 GHz explains the strong single-thread showings in the R15 and Geekbench tests, where it posted 1442 points single-core and 5696 multi-core.

Notably, both processors cluster with very different rival sets despite near-identical averages. The Atom's closest competitors in the database are the AMD Ryzen 3 PRO 5350GE and Ryzen 7 4800U (both with average scores of 3218, a dead heat), plus the Intel Core i5-1240P at 3202 and Core i3-13100T at 3198. The Ryzen 7 PRO 5850U's nearest rivals are the Ryzen 3 5300GE at 3160, the Ryzen 5 5560U at 3162, and two older Xeons, the E5-2676 v3 at 3163 and E5-2650 v4 at 3154. In short: choose the Atom for dense, parallel, always-on throughput; choose the Ryzen for a balanced mobile workload with graphics and a tight power envelope.

FAQ

Q: Which processor is faster overall?

A: Neither wins outright. Each takes two of the four head-to-head benchmarks. The Ryzen 7 PRO 5850U wins both Cinebench R15 tests by 23.6 and 30.4 percent, while the Atom P5342 wins both Cinebench R23 tests by 27.6 and 11.7 percent. Their average benchmark scores, 3217 and 3159, differ by well under two percent.

Q: Which chip is better for single-threaded work?

A: It depends on the test generation. In Cinebench R15 single-core the Ryzen leads 227 to 158, but in Cinebench R23 single-core the Atom leads 1570 to 1405. The Ryzen also posts 1442 in Geekbench single-core, a test where the Atom has no recorded score.

Q: Do both processors support ECC memory?

A: No. The Atom P5342 supports ECC, consistent with its server role. The Ryzen 7 PRO 5850U does not, which is normal for its mobile segment.

Q: How do their power envelopes compare?

A: The Atom P5342 is rated at 71 W TDP; the Ryzen 7 PRO 5850U is rated at 15 W. That is a large gap, and it frames the Ryzen's R15 results as especially strong given its power budget.

Q: Does either processor include integrated graphics?

A: The Ryzen 7 PRO 5850U includes Radeon Vega 8 graphics. The Atom P5342 has no integrated graphics listed and would require a discrete solution or platform graphics.

Q: Which platform offers more PCIe connectivity?

A: The Atom P5342 provides 16 lanes of PCIe Gen 3 from the CPU, double the Ryzen's 8 lanes, also Gen 3. That favors add-in cards and storage expansion on the server side.

Architecture Differences

The two processors come from fundamentally different architectural lineages. The Atom P5342 is built on Intel's 10 nm process at Intel's own foundry, carries the Snow Ridge codename, and belongs to the Atom family using the Tremont generation of cores. Its 16 cores each provide one thread, for 16 threads total, and the design emphasizes parallel density over per-core speed. Its base clock is 2.20 GHz and no boost clock is recorded, meaning the part runs at a consistent frequency rather than bursting for short workloads. Cache is organized as 64 KB of L1 per core and an unusually large 4.5 MB of L2 per module, with no L3 listed. This module-based L2 structure suits its many-core, throughput-oriented design.

The Ryzen 7 PRO 5850U is a Cezanne-U part from AMD's 5000 series, built on TSMC's 7 nm process with the Zen 3 architecture. It has 8 cores and 16 threads thanks to simultaneous multi-threading, a base clock of 1.9 GHz, and a boost clock of 4.40 GHz, which is more than double its base frequency and the key to its strong burst performance. Its cache hierarchy is 64 KB of L1 per core, 512 KB of L2 per core, and a shared 16 MB L3, a layout that concentrates resources into fewer, wider cores. The database records 10,700 million transistors on a 180 mm² die for the Ryzen; no transistor or die-size figures are recorded for the Atom.

Feature differences follow the same split. The Ryzen integrates Radeon Vega 8 graphics; the Atom integrates nothing. The Atom supports ECC memory for data integrity in server deployments; the Ryzen does not. Both support DDR4 on a dual-channel bus, though the Ryzen's memory bandwidth is higher at 51.2 GB/s versus 42.7 GB/s. Both processors remain in active production status, and both have locked multipliers, so neither offers overclocking headroom.

Specification Differences

The two spec sheets diverge on nearly every line that matters:

• Cores and threads: Atom P5342 has 16 cores and 16 threads; Ryzen 7 PRO 5850U has 8 cores and 16 threads.
• Clocks: Atom base 2.20 GHz with no boost recorded; Ryzen base 1.9 GHz, boost 4.40 GHz.
• TDP: 71 W for the Atom versus 15 W for the Ryzen.
• Socket: Intel BGA 2106 versus AMD Socket FP6, both soldered/mobile-style packages.
• Process and foundry: 10 nm at Intel versus 7 nm at TSMC.
• Cache: 4.5 MB L2 per module with no L3 on the Atom; 512 KB L2 per core plus 16 MB shared L3 on the Ryzen.
• Memory bandwidth: 42.7 GB/s versus 51.2 GB/s, both DDR4 dual-channel.
• ECC: supported on the Atom only.
• PCIe: 16 Gen 3 lanes versus 8 Gen 3 lanes from the CPU.
• Graphics: none on the Atom; Radeon Vega 8 on the Ryzen.
• Market segment and dates: Server/Workstation, released June 2022, versus Mobile, released March 2021. Launch MSRP of $708 for the Atom; none recorded for the Ryzen.

Head-to-Head Benchmarks

The four recorded head-to-head tests split evenly, and the divergence between R15 and R23 results deserves attention.

The Ryzen's wins come in Cinebench R15. In multi-core it scored 1467 against the Atom's 1121, a 23.6 percent advantage, and in single-core it scored 227 against 158, a 30.4 percent advantage. Given that the Ryzen must do this with 8 cores inside a 15 W envelope, these results reflect how effectively its high 4.40 GHz boost and Zen 3 architecture convert power into performance. The 30.4 percent single-core gap in R15 is the largest margin in the entire head-to-head set.

The Atom's wins come in Cinebench R23, the newer and more demanding test. Here the standings flip: 11122 versus 8716 in multi-core, a 27.6 percent Atom advantage, and 1570 versus 1405 in single-core, an 11.7 percent Atom lead. The multi-core reversal relative to R15 suggests the Atom's 16 physical cores sustain throughput better under a longer, heavier rendering load, while the Ryzen's fewer threads and constrained power budget give ground over time. Even the Atom's single-core win in R23 is notable, since the same test type in R15 went decisively the other way.

The Ryzen also carries Geekbench results the Atom lacks: 5696 multi-core and 1442 single-core. Those figures sit within the band established by the Cinebench data and reinforce the picture of a processor with strong burst behavior.

Aggregate context confirms the parity. Both chips sit at the 53rd percentile versus all CPUs in the database, with average scores of 3217 and 3159, a difference under one percent. Each also faces rivals within a fraction of a percent of its own average, meaning neither holds a meaningful edge in overall standing. The choice therefore rests not on which is faster, but on where the performance lives: the Atom delivers it through parallel width, ECC, and PCIe lanes in a server package; the Ryzen delivers it through clock speed, efficiency, and integrated graphics in a mobile one.
