AMD Ryzen AI 9 365 vs Intel Xeon 6357P Comparison

Head-to-Head Benchmarks

The benchmark data reveals a clear split between the Intel Xeon 6357P and the AMD Ryzen AI 9 365. Intel wins 10 of the 15 recorded head-to-head comparisons, while AMD takes 5. The overall average benchmark scores are close, with Intel at 40630 and AMD at 40048, a difference of roughly 1.5%, but the per-test results show two very different performance profiles.

The largest Intel victories come in the Cinebench suite. In Cinebench R23 single-core, the Xeon 6357P scores 3691 against 1992 for the Ryzen, a 85.3% advantage. That is the single biggest gap in the entire comparison. The multi-core result in Cinebench R23 also favors Intel heavily: 26145 versus 18698, a 39.8% lead. In Cinebench R15 single-core, Intel leads 372 to 303, a 22.8% margin, though the Ryzen wins the R15 multi-core test 2842 to 2635, a 7.3% advantage.

PassMark tests reinforce the Intel lead in compute-heavy workloads. The Xeon scores 2305 in PassMark physics versus 1704 for the Ryzen, a 35.3% margin. Floating point math goes to Intel at 74460 versus 62802, an 18.6% lead. Prime number finding favors Intel 149 to 117, a 27.4% gap. PassMark multi-thread goes to Intel 30759 to 29467, a 4.4% edge. Single-thread PassMark results show Intel at 4233 versus 3841, a 10.2% advantage. Data encryption is essentially tied, with Intel at 18324 and AMD at 18297, a 0.1% difference.

AMD's wins are narrower but consistent in specific areas. PassMark random string sorting goes to the Ryzen 39447 to 35495, a 10% margin. Integer math favors AMD 101831 to 97375, a 4.4% lead. Extended instructions go to AMD 25113 to 24490, a 2.5% edge. Data compression is nearly identical, with AMD at 354510 and Intel at 353521, a 0.3% difference. The Cinebench R15 multi-core result completes the AMD win list.

The pattern is clear: Intel dominates in single-threaded performance and in floating-point or physics-heavy workloads, while AMD takes the lead in memory-latency-sensitive tasks like string sorting and integer math. The average benchmark scores place both processors at the 87th percentile among all CPUs in the database, meaning they sit in the same overall performance tier despite their divergent strengths.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon 6357P is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, and is manufactured on Intel's 10 nm process with a die size of 257 mm². It has 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 5.40 GHz. The thermal design power is 80 W, and it uses Intel Socket 1700.

The AMD Ryzen AI 9 365 uses Zen 5 architecture with the Strix Point codename, combining Zen 5 and Zen 5c cores. It is manufactured on TSMC's 4 nm process with a die size of 233 mm². The chip has 10 cores and 20 threads, with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. Its thermal design power is 28 W, and it uses AMD Socket FP8.

Cache configurations differ significantly. Both have 80 KB of L1 cache per core. Intel provides 2 MB of L2 cache per core, while AMD provides 1 MB per core. For L3 cache, Intel has 24 MB shared, while AMD has 16 MB total. This gives Intel a larger last-level cache, which helps explain its strong single-threaded results.

Memory support also diverges. Intel supports both DDR4 and DDR5 memory, while AMD supports DDR5 and LPDDR5X. Both are dual-channel. AMD lists a memory bandwidth of 89.6 GB/s, while Intel does not specify a bandwidth figure in the database. Intel supports ECC memory; AMD does not.

PCIe generation differs as well. Intel offers Gen 5 with 16 lanes from the CPU, while AMD offers Gen 4 with 16 lanes. The Intel Xeon includes no integrated graphics, while the Ryzen AI 9 365 includes the Radeon 880M integrated GPU. Intel's market segment is Server/Workstation, while AMD's is Mobile.

The release dates differ by roughly eight months. Intel was released on 2025-02-23, while AMD was released on 2024-06-30. Intel has a launch MSRP of $556, while AMD has no listed launch MSRP. Both processors are currently active in production and both have locked multipliers.

Where Each One Wins

The Intel Xeon 6357P is the clear choice for workloads that depend on raw single-thread performance and floating-point throughput. Its 85.3% lead in Cinebench R23 single-core and 22.8% lead in Cinebench R15 single-core make it strong for lightly threaded applications where clock speed matters. The 5.40 GHz boost clock compared to AMD's 5.00 GHz boost clock supports this. The 39.8% advantage in Cinebench R23 multi-core, despite having fewer cores and threads, indicates that per-core efficiency and cache size are doing substantial work. The 24 MB shared L3 cache versus AMD's 16 MB likely contributes to these results.

Physics simulation and floating-point math are also Intel territory. The 35.3% lead in PassMark physics and 18.6% lead in floating point math suggest the Xeon handles scientific and simulation workloads well. The 27.4% advantage in prime number finding reinforces this. Server and workstation buyers who run ECC memory and need reliability features will find the Intel part matches their requirements, as it supports ECC while AMD does not. The Gen 5 PCIe support also gives Intel an edge in I/O bandwidth for server workloads.

The AMD Ryzen AI 9 365 wins in workloads that involve data manipulation and memory access patterns. The 10% lead in random string sorting suggests better memory subsystem behavior for pointer-chasing workloads. The 4.4% lead in integer math and 2.5% lead in extended instructions make it suitable for general productivity and encryption-adjacent tasks, though data encryption itself is essentially tied at 0.1%. The 7.3% win in Cinebench R15 multi-core, where its 10 cores and 20 threads can flex, indicates that heavily parallel workloads with lower per-thread demands can benefit from AMD's higher core count.

For mobile users, the Ryzen has clear advantages: a 28 W TDP versus 80 W, integrated Radeon 880M graphics, and support for LPDDR5X memory. It is designed for the Mobile market segment, while Intel targets Server/Workstation. The AMD part also supports a higher memory bandwidth figure of 89.6 GB/s. Users who need a compact, power-efficient platform with built-in graphics will prefer the Ryzen, while those who need maximum per-core speed and ECC support will prefer the Xeon.
