Analysis: AMD EPYC 7402P vs Intel Core i5-8350U
The AMD EPYC 7402P and Intel Core i5-8350U are processors from different worlds. The recorded data shows a complete sweep for the EPYC 7402P, which wins all six head-to-head benchmark comparisons. The i5-8350U, a mobile processor, offers integrated graphics and a drastically lower power envelope, but it cannot match the server-class EPYC in any measured compute test.
The Verdict
The AMD EPYC 7402P is the definitive choice for server and workstation workloads. It wins 6 out of 6 head-to-head tests, with zero wins for the Intel Core i5-8350U. The EPYC's average benchmark score is 9529, compared to 8998 for the i5. Both processors sit in the 65th percentile of all CPUs, but this parity in overall standing masks the massive gap in raw compute. The EPYC's nearest rivals include the Intel Core i7-7700HQ, which it leads by 0.4%, the Intel Atom x7835RE, which it leads by 1.1%, and the Intel Xeon Platinum 8180, which it leads by 1.3%. It trails the Intel Core i5-1035G1 by 1.6%. The i5-8350U, on the other hand, trails the Intel Core i5-1135G7 by 0.6% and leads the Intel Xeon Gold 6330 by 0.7%, as well as the Intel Core i7-8650U by 0.7%. The verdict is clear: the EPYC 7402P is for heavy multi-threaded compute, while the i5-8350U is for low-power mobile systems where its 15W TDP and integrated UHD 620 graphics are essential. The i5 has no benchmark wins in this comparison, making the EPYC the only choice for performance.
Architecture Differences
The two processors are built on fundamentally different architectures. The EPYC 7402P uses AMD's Zen 2 architecture, codenamed Rome, on a 7 nm process at TSMC. The i5-8350U uses Intel's Kaby Lake architecture, codenamed Kaby Lake-R, on a 14 nm process at Intel. The EPYC packs 24 cores and 48 threads, while the i5 has 4 cores and 8 threads. The EPYC features 96 KB of L1 cache per core, 512 KB of L2 per core, and a massive 128 MB shared L3 cache. The i5 has 64 KB of L1 per core, 256 KB of L2 per core, and only 6 MB of shared L3. The EPYC supports eight-channel DDR4 memory with a bandwidth of 204.8 GB/s, while the i5 supports DDR4 but has no recorded memory bus or bandwidth in the database. The EPYC supports ECC memory and provides PCIe Gen 4 with 128 lanes, while the i5 has no ECC support and no recorded PCIe lanes. The EPYC has no integrated graphics, while the i5 includes UHD 620. The EPYC uses the AMD Socket SP3, while the i5 uses Intel BGA 1356. The EPYC has a TDP of 180W, the i5 has a TDP of 15W. The EPYC die size is 74 mm² with 3,800 million transistors, while the i5 die size is 123 mm² with no transistor count recorded. The EPYC was released in 2019, the i5 in 2017. These architectural differences explain the performance gap: the EPYC's larger core count, massive L3 cache, and high-bandwidth memory system are designed for throughput, while the i5's smaller die and integrated graphics target efficiency and portability.
Where Each One Wins
In the recorded head-to-head benchmarks, the AMD EPYC 7402P wins every single test. It wins all six Cinebench tests, covering both single-core and multi-core workloads across R15, R20, and R23. The i5-8350U has zero wins. However, the i5-8350U does have capabilities outside the head-to-head tests. It features integrated UHD 620 graphics, which the EPYC lacks entirely. This makes the i5 suitable for systems that require a display output without a discrete graphics card. Additionally, the i5's 15W TDP is drastically lower than the EPYC's 180W, making it viable for fanless or battery-powered ultraportable designs. The EPYC's wins are absolute in compute performance, but the i5 wins on integration and power efficiency. The data shows the EPYC's average score of 9529 places it in the 65th percentile of all CPUs, and the i5 also sits in the 65th percentile, indicating they are comparable in overall standing despite the massive head-to-head deltas. The i5's Passmark results, such as 79781 in data compression and 2075 in data encryption, show it has its own strengths, but these are not part of the head-to-head comparison.

Head-to-Head Benchmarks
The head-to-head results are a complete sweep for the AMD EPYC 7402P. In Cinebench R15 multi-core, the EPYC scores 3749 against the i5's 521, a 619.6% advantage. In R15 single-core, the EPYC scores 529 against 73, a 624.7% advantage. Moving to Cinebench R20, the EPYC scores 15621 in multi-core versus 2172, a 619.2% delta, and 2205 in single-core versus 306, a 620.6% delta. In Cinebench R23, the EPYC scores 37195 in multi-core versus 5173, a 619% delta, and 5251 in single-core versus 730, a 619.3% delta. The deltas are remarkably consistent, hovering around 620% across all tests. This indicates that the EPYC's advantage is not workload-specific but rather a fundamental performance gap. The EPYC's nearest rival, the Intel Core i7-7700HQ, has an average score of 9493, which the EPYC leads by 0.4%. The i5-8350U's nearest rival, the Intel Core i5-1135G7, has an average score of 9053, which the i5 trails by 0.6%. These context points show that while the EPYC is near the top of its class, the i5 is also competitive within its own mobile segment, but the absolute gap between the two is enormous.
