AMD Ryzen 7 PRO 8840HS vs Intel Xeon 6357P Comparison

Where Each One Wins

The recorded benchmark data splits cleanly along workload type. The Intel Xeon 6357P wins 13 of the 15 head-to-head comparisons, while the AMD Ryzen 7 PRO 8840HS takes only 2. The Intel part dominates in compute-heavy, single-thread-sensitive, and physics-based tasks. Its most extreme advantage appears in Cinebench R23 single-core, where it leads by 114.1%, and in passmark find prime numbers, where it leads by 77.4%. These are large, structural gaps, not marginal differences.

The AMD Ryzen 7 PRO 8840HS wins in passmark data encryption (by 2.7%) and passmark random string sorting (by 6.4%). The encryption result is notable because it suggests the AMD part has a more efficient cryptographic execution path, despite trailing in most other integer and floating-point workloads. The random string sorting win points to a memory-access pattern or cache behavior that favors the AMD design, even though the Intel part has a larger L3 cache.

Looking at the aggregate scores, the Intel Xeon 6357P posts an average benchmark score of 40630 against the AMD part's 39603. Both sit at the 87th percentile among all CPUs in the database. The Intel part's nearest rivals include the Intel Core 5 223PE (average score 40585, 0.1% behind), the Intel Core 7 253PE (40557, 0.2% behind), and the Intel Core Ultra X7 368H (40518, 0.3% behind). The AMD part's nearest rivals include the AMD Ryzen AI 7 450 (39485, 0.3% behind), the AMD Ryzen 7 9800X3D (39768, 0.4% ahead), and the AMD Ryzen 7 PRO 8845HS (39325, 0.7% behind). These deltas are small, meaning each processor sits tightly within its own performance cluster.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon 6357P uses Raptor Lake architecture, specifically the Raptor Lake-R refresh, fabricated on Intel's 10 nm process with a die size of 257 mm². It is part of the Xeon 6 generation and targets the Server/Workstation segment. The AMD Ryzen 7 PRO 8840HS uses Zen 4 architecture under the Hawk Point codename, fabricated on TSMC's 4 nm process with a die size of 178 mm² and 25,000 million transistors. It belongs to the Ryzen 7 PRO 8000 series and targets the Mobile segment.

Both have 8 cores and 16 threads, so the thread count is identical. The Intel part has a base clock of 3.00 GHz and a boost clock of 5.40 GHz. The AMD part has a higher base clock of 3.30 GHz but a lower boost clock of 5.10 GHz. The Intel part has a higher TDP of 80 watts, while the AMD part is rated at 28 watts, reflecting its mobile orientation.

Cache layouts differ significantly. The Intel Xeon 6357P provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The AMD Ryzen 7 PRO 8840HS provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part has more cache at every level, which likely contributes to its large lead in single-thread and physics workloads.

Memory support also differs. The Intel part supports both DDR4 and DDR5 across a dual-channel bus, while the AMD part supports only DDR5, also dual-channel, with a rated memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity differs: the Intel part offers Gen 5 with 16 lanes (CPU only), while the AMD part offers Gen 4 with 20 lanes (CPU only). The Intel part has no integrated graphics, while the AMD part includes Radeon 780M graphics. The Intel part uses Intel Socket 1700, the AMD part uses AMD Socket FP7.

Head-to-Head Benchmarks

The single-core results show the clearest separation. In Cinebench R15 single-core, the Intel Xeon 6357P scores 372 against the AMD part's 271.5, a 37% lead. In Cinebench R23 single-core, the gap widens dramatically: 3691 versus 1724, a 114.1% advantage. This is the largest delta in the entire comparison. The PassMark single-thread test confirms the trend, with the Intel part scoring 4233 versus 3692, a 14.7% lead. The lower boost clock of the AMD part (5.10 GHz versus 5.40 GHz) and smaller cache per core help explain this pattern.

Multi-core results also favor Intel, but with varying margins. In Cinebench R15 multi-core, the Intel part scores 2635 versus 2458, a 7.2% lead. In Cinebench R23 multi-core, the Intel part scores 26145 versus 14784, a 76.8% lead. The PassMark multithread test shows a smaller gap: 30759 versus 26646, a 15.4% lead. The integer math test is close, with the Intel part scoring 97375 versus 93342, only 4.3% ahead. The floating-point math test shows a larger gap: 74460 versus 55739, a 33.6% lead.

Physics performance heavily favors Intel. The passmark physics test shows 2305 versus 1351, a 70.6% lead. Prime number finding also favors Intel: 149 versus 84, a 77.4% lead. Data compression shows a 13.6% advantage for Intel (353521 versus 311199), while extended instructions show a 9.8% advantage (24490 versus 22298).

The AMD part's two wins are worth examining closely. In data encryption, it scores 18838 versus 18324, a 2.7% edge. In random string sorting, it scores 37922 versus 35495, a 6.4% edge. These are modest but consistent wins, suggesting that the AMD part has particular strengths in memory reordering and cryptographic operations, despite losing overall.
