Intel Atom P5342 vs Intel Xeon E-2374G Comparison

FAQ

Q: Which processor has a higher single-core performance?

A: The Intel Xeon E-2374G wins all three single-core Cinebench tests. It scores 161 in Cinebench R15 single-core versus 158 for the Atom P5342, 672 versus 659 in R20, and 1600 versus 1570 in R23. The margin is a consistent 1.9% to 2% across these tests.

Q: How do the two processors compare in multi-core workloads?

A: The Xeon E-2374G also leads in every multi-core benchmark, but by a smaller margin than its core count difference might suggest. It scores 1142 versus 1121 in Cinebench R15, 4760 versus 4671 in R20, and 11335 versus 11122 in R23. Each multi-core win is exactly a 1.9% advantage.

Q: What is the core and thread configuration for each chip?

A: The Xeon E-2374G has 4 cores and 8 threads, while the Atom P5342 has 16 cores and 16 threads. Despite having four times the core count, the Atom does not support simultaneous multithreading, so its thread count equals its core count.

Q: Which processor has a higher base clock speed?

A: The Xeon E-2374G has a base clock of 3.70 GHz. The Atom P5342 has a base clock of 2.20 GHz. The Xeon also has a boost clock of 5.00 GHz, while the Atom has no boost clock listed in the database.

Q: Do both processors support ECC memory?

A: Yes, both the Intel Xeon E-2374G and the Intel Atom P5342 support ECC memory. Both also use DDR4 memory with a dual-channel memory bus.

Q: What is the process node for each processor?

A: The Xeon E-2374G is built on Intel's 14 nm process node, while the Atom P5342 uses the 10 nm node. The Atom also has a smaller die size, though the database does not list a specific size for it, whereas the Xeon die measures 276 mm².

Architecture Differences

The Intel Xeon E-2374G belongs to the Xeon E-2300 series and is built on the Rocket Lake architecture, specifically the Rocket Lake-E codename. It uses a 14 nm process node from Intel's own foundry. The die size is 276 mm². The Atom P5342, by contrast, is based on the Snow Ridge codename with a Tremont generation microarchitecture, and it uses a 10 nm process node, also fabricated by Intel. The database does not list a die size for the Atom.

Core configuration is the most striking architectural divergence. The Xeon has 4 cores and 8 threads, meaning each core can handle two threads. The Atom has 16 cores and 16 threads, with no simultaneous multithreading support. This means the Atom relies entirely on raw core count, while the Xeon depends on higher clock speeds and thread-level parallelism from fewer, more capable cores.

Cache hierarchies differ substantially. The Xeon E-2374G has 80 KB of L1 cache per core, 512 KB of L2 cache per core, and an 8 MB shared L3 cache. The Atom P5342 has 64 KB of L1 cache per core and 4.5 MB of L2 cache per module, with no L3 cache listed in the database. The Xeon's larger per-core L1 and shared L3 cache suggest a design optimized for latency-sensitive single-threaded work, while the Atom's module-based L2 arrangement points toward a many-core, throughput-oriented design.

Memory bandwidth also separates the two. The Xeon supports 51.2 GB/s of memory bandwidth, while the Atom is rated at 42.7 GB/s, a difference of 8.5 GB/s. Both use DDR4 memory and dual-channel buses. PCIe capabilities differ as well: the Xeon provides Gen 4 with 20 lanes (CPU only), while the Atom provides Gen 3 with 16 lanes (CPU only). The Xeon also includes integrated graphics (UHD Graphics P750), whereas the Atom has no integrated graphics.

The sockets are incompatible. The Xeon uses Intel Socket 1200, while the Atom uses Intel BGA 2106, a soldered form factor. The Xeon has a 80 W TDP, while the Atom has a 71 W TDP. Both are locked processors, meaning the multiplier is not unlocked. The Xeon was released earlier, on September 7, 2021, while the Atom followed on June 5, 2022.

The Verdict

The data clearly favors the Intel Xeon E-2374G across every benchmark in the head-to-head comparison. It wins all six Cinebench tests, including both single-core and multi-core variants. The margins are narrow, ranging from 1.9% to 2%, but they are consistent. If the selection is based purely on measured performance in the database, the Xeon E-2374G is the stronger processor.

However, the choice depends on workload characteristics not fully captured by Cinebench. The Atom P5342 has 16 cores versus the Xeon's 4 cores, and it operates at a lower TDP of 71 W versus 80 W. For workloads that scale well beyond the Cinebench suite, such as high-density virtualized environments or packet processing with many parallel threads, the Atom's core count could be advantageous. The database does not include such tests, so this remains an inference from the core count, not a measured result.

For single-threaded or lightly threaded workloads, the Xeon E-2374G is the clear pick. Its 5.00 GHz boost clock and 8 MB shared L3 cache give it a decisive edge in latency-sensitive tasks. The Atom, with no boost clock and no L3 cache, structures its performance around sustained multi-core throughput at a modest 2.20 GHz base clock.

The Xeon also offers better memory bandwidth (51.2 GB/s versus 42.7 GB/s) and newer PCIe Gen 4 connectivity. The Atom counters with a smaller process node (10 nm versus 14 nm) and a lower TDP. Both support ECC memory, making either viable for server or workstation deployments where data integrity is paramount.

The percentile ranking versus all CPUs is identical at the 53rd percentile for both, and their average benchmark scores are close: 3278 for the Xeon and 3217 for the Atom. This parity suggests that in general-purpose workloads, the two are near equivalents, with the Xeon holding a slight edge in the recorded tests.

Head-to-Head Benchmarks

The head-to-head benchmark data records six Cinebench tests, and the Intel Xeon E-2374G wins all six. The largest single win is in Cinebench R20 single-core, where the Xeon scores 672 against the Atom's 659, a 2% advantage. All other tests show a 1.9% delta.

In Cinebench R15 multi-core, the Xeon scores 1142 versus the Atom's 1121. In R15 single-core, the margin is 161 versus 158. The R20 multi-core test shows 4760 versus 4671, and R20 single-core shows 672 versus 659. In R23 multi-core, the scores are 11335 and 11122, while R23 single-core records 1600 and 1570. The Xeon's wins are consistent across both workload types and all three versions of Cinebench.

The average benchmark score for the Xeon is 3278, while the Atom sits at 3217. The Xeon's nearest rival in the database is the Intel Core i3-12100T with an average score of 3277 (0% delta), while the Atom's nearest rival is the AMD Ryzen 3 PRO 5350GE at 3218 (0% delta). These rival comparisons place both chips in the same performance tier, despite their different architectural approaches.

The Xeon's multi-core wins are notable because it achieves them with only 4 cores and 8 threads against the Atom's 16 cores and 16 threads. This indicates that the Xeon's higher clock speeds and per-core efficiency more than compensate for the Atom's core-count advantage in the Cinebench workload. The single-core results reinforce this interpretation: the Xeon's 5.00 GHz boost clock drives a 1.9% to 2% edge over the Atom's 2.20 GHz base clock.

Where Each One Wins

Intel Xeon E-2374G: The database records wins for the Xeon in all six head-to-head benchmarks. It is the better choice for any workload measured by Cinebench, including both single-threaded and multi-threaded rendering tasks. Its 5.00 GHz boost clock, 8 MB shared L3 cache, and 51.2 GB/s memory bandwidth position it for latency-sensitive applications. The PCIe Gen 4 interface with 20 lanes provides faster peripheral connectivity than the Atom's Gen 3 with 16 lanes. The integrated UHD Graphics P750 also gives it a display output capability that the Atom lacks entirely. For server or workstation tasks that rely on higher clock speeds, such as database query processing or single-threaded application logic, the Xeon is the superior option.

Intel Atom P5342: While the Atom loses every recorded benchmark, its architecture suggests strengths in unmeasured areas. Its 16 cores provide four times the core count of the Xeon, which could benefit workloads that scale linearly with core count beyond the Cinebench suite. The 10 nm process node offers a more modern fabrication, and the lower 71 W TDP means less power draw. The absence of a boost clock and L3 cache indicates a design focused on sustained, predictable throughput rather than burst performance. For dense, parallel workloads such as network packet processing or containerized microservices that can utilize 16 independent threads, the Atom's core count is its primary asset. The BGA 2106 socket also suggests an embedded or fixed-system deployment model, which may suit specific industrial or edge computing scenarios. The database does not measure these workloads, so this advantage is inferred from the core count difference, not from recorded benchmark results.
