AMD EPYC 7351P vs Intel Xeon E-2388G Comparison

Head-to-Head Benchmarks

The benchmark data splits the two processors into distinct performance profiles. The AMD EPYC 7351P takes the lead in six of the eight recorded tests, while the Intel Xeon E-2388G secures two decisive victories in Geekbench workloads.

In Cinebench testing, the AMD EPYC 7351P consistently outperforms the Intel Xeon E-2388G by a narrow margin. The multi-core results show the EPYC scoring 2231 against the Xeon's 2009 in Cinebench R15, a 10% difference. That pattern repeats in Cinebench R20, where the EPYC posts 9296 versus 8374, again a 9.9% gap. Cinebench R23 multi-core follows the same trend: the EPYC scores 22135 while the Xeon reaches 19939, a 9.9% advantage. Single-core Cinebench results are similarly close, with the EPYC ahead by 9.9% to 10% in all three versions. The EPYC delivers 314 versus 283 in R15 single-core, 1312 versus 1181 in R20 single-core, and 3125 versus 2814 in R23 single-core.

The Intel Xeon E-2388G, however, dominates Geekbench. In Geekbench multi-core, the Xeon scores 9615 against the EPYC's 4607, a massive 108.7% advantage. The single-core Geekbench result is even more lopsided: the Xeon scores 2227 while the EPYC manages only 733, a 203.8% difference. These are the largest deltas in the entire comparison.

The overall benchmark average tells a different story. The Intel Xeon E-2388G has an average benchmark score of 5805, while the AMD EPYC 7351P sits at 5469. Both processors land at the 61st percentile among all CPUs in the database. The Xeon's nearest rivals include the AMD EPYC 7401P (5814 average, 0.2% behind), the Intel Xeon W-2175 (5770, 0.6% ahead of that rival), and the AMD Ryzen Threadripper 2920X (5730, 1.3% ahead). The EPYC 7351P's nearest rivals include the Intel Xeon W-1290P (5443 average, 0.5% behind), the AMD Ryzen Threadripper 1920 (5425, 0.8% behind), and the Intel Core i9-10900X (5555, 1.5% ahead of the EPYC).

The data suggests that the two processors excel in different workload types. The EPYC wins the Cinebench suite convincingly, while the Xeon wins Geekbench by an order of magnitude. These results point to fundamentally different optimization profiles, not just a simple performance hierarchy.

The Verdict

The verdict depends entirely on the application. For Cinebench-style rendering workloads, the AMD EPYC 7351P is the clear choice, winning every single Cinebench test by roughly 10%. Its 16 cores and 32 threads give it a structural advantage in multi-threaded tasks, and even in single-core Cinebench, it manages to edge out the Intel part despite a lower boost clock.

For Geekbench-style workloads, the Intel Xeon E-2388G is the definitive winner. Its 203.8% single-core advantage and 108.7% multi-core advantage are not incremental gains; they represent a completely different performance class in these tests. The Xeon's 5.10 GHz boost clock, compared to the EPYC's 2.90 GHz, likely explains this disparity.

The database percentile rankings place both CPUs at the same 61st percentile, meaning neither is categorically superior in the overall CPU landscape. The average benchmark scores, however, favor the Intel part: 5805 versus 5469, a 6.1% gap in the Xeon's favor. That average is heavily influenced by the extreme Geekbench results.

A buyer choosing strictly for Cinebench rendering should take the EPYC 7351P. A buyer prioritizing Geekbench-style integer and floating-point tests should take the Xeon E-2388G. The tiebreaker is the overall average, which leans toward Intel, but the margin is modest compared to the per-test deltas.

Where Each One Wins

AMD EPYC 7351P wins in Cinebench rendering. All six Cinebench tests (R15, R20, R23, both single-core and multi-core) go to the EPYC, with deltas from 9.9% to 10%. This consistency across three versions of the same benchmark suite indicates a stable architectural advantage in that specific workload. The EPYC's 16 cores and 32 threads, paired with 64 MB of shared L3 cache, provide the computational width that Cinebench rewards.

Intel Xeon E-2388G wins in Geekbench workloads. The Xeon's Geekbench multi-core score of 9615 more than doubles the EPYC's 4607, and the single-core score of 2227 nearly triples the EPYC's 733. These are not close contests. The Xeon's 5.10 GHz boost clock and 16 MB of shared L3 cache appear to drive this performance, though the database does not isolate the exact cause.

The EPYC wins on thread count and memory bandwidth. With 16 cores, 32 threads, and an eight-channel memory bus delivering 170.6 GB/s, the EPYC is built for parallel throughput. The Xeon offers 8 cores, 16 threads, and a dual-channel bus at 51.2 GB/s. For workloads that scale with core count and memory bandwidth, the EPYC's specifications align with its Cinebench wins.

The Xeon wins on clock speed and PCIe generation. The Xeon's boost clock of 5.10 GHz is far above the EPYC's 2.90 GHz. Additionally, the Xeon supports PCIe Gen 4 with 20 CPU lanes, while the EPYC uses PCIe Gen 3. The Xeon also includes integrated UHD Graphics P750, which the EPYC lacks entirely.

Architecture Differences

The two processors come from different architectural lineages. The Intel Xeon E-2388G is built on Rocket Lake-E, a 14 nm design from Intel's own foundry. It uses the Xeon E-2300 series platform with a 276 mm² die size. The AMD EPYC 7351P uses the Zen architecture under the Naples codename, also on a 14 nm process, but fabricated by GlobalFoundries with a 213 mm² die and 4,800 million transistors.

Core and cache configurations differ substantially. The Xeon offers 8 cores and 16 threads with 80 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The EPYC offers 16 cores and 32 threads with 96 KB of L1 per core, 512 KB of L2 per core, and a much larger 64 MB of shared L3 cache. The EPYC's transistor count of 4,800 million versus the Xeon's unspecified count suggests a denser design despite the smaller die.

Memory architecture splits them further. The Xeon uses a dual-channel DDR4 bus with 51.2 GB/s bandwidth. The EPYC uses an eight-channel DDR4 bus with 170.6 GB/s bandwidth, more than three times the Xeon's figure. Both support ECC memory.

PCIe capabilities differ by generation. The Xeon supports PCIe Gen 4 with 20 CPU lanes. The EPYC supports PCIe Gen 3. The Xeon also includes integrated UHD Graphics P750, while the EPYC has no integrated graphics. The EPYC has an unlocked multiplier, while the Xeon does not.

The release dates are separated by years: the EPYC launched in 2017, the Xeon in 2021. The Xeon carries a launch MSRP of $539, while the EPYC has no recorded launch MSRP.
