Intel Atom x7433RE vs Intel Xeon E-2388G Comparison

The Verdict

The data is unambiguous: the Intel Xeon E-2388G is the decisive winner across every recorded head-to-head benchmark, taking all 5 wins with no victories for the Atom x7433RE. The Xeon delivers multi-core scores that are roughly 464% higher than the Atom in Cinebench R15, R20, and R23 tests, while single-core performance shows a similar margin of about 464% to 465%. This is not a close contest by any measurement.

The Xeon E-2388G is the correct choice for anyone needing serious computing throughput. Its 8 cores with 16 threads, combined with a 3.20 GHz base and 5.10 GHz boost clock, place it in a different performance class entirely. The Atom x7433RE, with 4 cores and 4 threads at a 1.50 GHz base and 3.40 GHz boost, is suited only for scenarios where minimal power draw and compact physical footprint take priority over raw speed.

The Atom does have one clear advantage in the recorded data: its 9W TDP versus the Xeon's 95W TDP. For fanless or passively cooled industrial systems, battery-powered edge devices, or environments where heat dissipation is a challenge, the Atom is the pragmatic pick. However, benchmark results indicate that choosing the Atom means accepting roughly a fifth of the multi-core performance of the Xeon, a trade-off that only makes sense for specific low-power deployments.

The database places both processors at the 61st percentile among all CPUs, which is notable given their completely different performance profiles. The Xeon achieves this through raw compute capability, while the Atom reaches the same percentile ranking through a balanced set of recorded workloads including PassMark tests that cover integer math, floating-point math, and data compression. The Xeon's average benchmark score of 5805 slightly edges out the Atom's 5601, but the margin is modest compared to the massive deltas in the Cinebench tests.

Architecture Differences

The two processors come from entirely different Intel design families. The Xeon E-2388G uses the Rocket Lake architecture, specifically the Rocket Lake-E variant, built on a 14 nm process node with a die size of 276 mm². The Atom x7433RE uses the Amston Lake architecture with Gracemont cores, built on a 10 nm process node. This node difference is significant: the Atom's newer, denser process allows for dramatically lower power consumption despite having half the cores.

Cache hierarchies differ substantially. The Xeon provides 80 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The Atom provides 96 KB of L1 per core, a shared 2 MB L2, and a shared 6 MB L3. The Xeon's per-core L2 allocation suits its high-clock design, while the Atom's shared L2 arrangement reflects a more power-efficient, lower-frequency approach.

Memory support diverges as well. The Xeon supports DDR4 memory over a dual-channel bus with 51.2 GB/s bandwidth and includes ECC memory support. The Atom supports both DDR4 and DDR5 but over a single-channel bus with 38.4 GB/s bandwidth and no ECC support. The Xeon's higher memory bandwidth and ECC capability matter for workstation and server reliability, while the Atom's single-channel design reduces power and board complexity.

PCIe connectivity also differs: the Xeon offers Gen 4 with 20 lanes from the CPU, while the Atom offers Gen 3 with 9 lanes. The Xeon's newer PCIe generation and greater lane count allow for faster storage and expansion cards. Integrated graphics are present on both, with the Xeon featuring UHD Graphics P750 and the Atom featuring UHD Graphics 32EU, though the benchmark data does not compare GPU performance.

Where Each One Wins

The Xeon E-2388G wins in every measured compute benchmark. Its 8-core, 16-thread configuration with a 5.10 GHz boost clock dominates multi-threaded workloads. Cinebench R23 multi-core shows a score of 19939 versus the Atom's 3535, a 464% advantage. Single-core performance follows the same pattern: 2814 versus 499 in Cinebench R23 single-core, a 463.9% lead. The Xeon is built for server and workstation tasks such as compilation, rendering, virtualization, and database workloads where thread count and clock speed translate directly into throughput.

The Atom x7433RE wins in power efficiency, a domain not captured by the benchmark scores but clearly visible in the TDP figures. At 9W, the Atom consumes roughly one-tenth the power of the Xeon's 95W. The Atom is a mobile-segment processor on the Intel BGA 1264 socket, whereas the Xeon uses the socketed Intel Socket 1200. The Atom's 10 nm process and minimal power draw make it suitable for always-on edge devices, industrial controllers, and portable systems where sustained low-power operation is the primary requirement.

The Atom also shows some capability in specific PassMark workloads that are not part of the head-to-head comparison. Its PassMark data compression score of 43671 and integer math score of 13054 suggest it can handle light data-processing tasks without issue. However, its PassMark find prime numbers score of 19 and physics score of 323 indicate severe limitations in computationally intensive workloads. The Xeon, by contrast, has no recorded PassMark scores in the database, so direct comparisons in these specific tests are not possible.

Head-to-Head Benchmarks

The recorded head-to-head data shows a consistent and overwhelming advantage for the Xeon E-2388G across all five Cinebench tests. The smallest delta is 463.9% in Cinebench R23 single-core, where the Xeon scores 2814 against the Atom's 499. The largest margin is 465.1% in Cinebench R20 single-core, with scores of 1181 and 209 respectively.

Multi-core results show the same magnitude of difference. Cinebench R15 multi-core has the Xeon at 2009 and the Atom at 356, a 464.3% delta. Cinebench R20 multi-core shows 8374 versus 1484, also a 464.3% delta. Cinebench R23 multi-core rounds out the comparison with 19939 versus 3535, a 464% delta.

Notably, the single-core and multi-core deltas are nearly identical across all tests, hovering around 464% to 465%. This indicates that the Xeon's advantage comes from both higher clock speeds and superior per-core architecture, not just from having more cores. The Atom's 1.50 GHz base clock, even with a 3.40 GHz boost, cannot approach the Xeon's 5.10 GHz boost in sustained single-core workloads.

The Xeon's nearest rivals in the database are all high-end server or workstation parts: the AMD EPYC 7401P with an average score of 5814 and a delta of -0.2%, the Intel Xeon W-2175 at 5770 with a 0.6% delta, the AMD Ryzen Threadripper 2920X at 5730 with a 1.3% delta, and the AMD EPYC 7351 at 5710 with a 1.7% delta. These small deltas show that the Xeon E-2388G performs in line with other established server processors, sitting within 2% of each rival.

The Atom's nearest rivals are a different class of processors: the Intel Core i7-12700T at 5606 with a -0.1% delta, the AMD Ryzen 7 PRO 3700 at 5610 with a -0.2% delta, the Intel Core i9-11900KB at 5587 with a 0.3% delta, and the Intel Celeron G6900 at 5561 with a 0.7% delta. These are mainstream or low-power desktop and mobile chips, and the Atom stays within 1% of each, confirming its positioning as a low-power but competitive processor for its segment.

Specification Differences

The socket types differ completely. The Xeon E-2388G uses Intel Socket 1200, a socketed platform for server and workstation boards. The Atom x7433RE uses Intel BGA 1264, a ball-grid-array package soldered directly to the motherboard, which is typical for mobile and embedded designs.
