AMD Ryzen AI 5 PRO 440 vs Intel Xeon 6357P Comparison

The AMD Ryzen AI 5 PRO 440 and Intel Xeon 6357P represent two fundamentally different design philosophies: a 28W mobile processor built on a 4nm process versus an 80W server/workstation chip on Intel’s 10nm node. The benchmark data shows a decisive performance hierarchy, with the Intel Xeon 6357P winning all 11 head-to-head comparisons, yet the AMD part’s efficiency metrics and platform features carve out a distinct identity. This analysis quantifies the performance gap, contextualizes it against nearest rivals, and examines the architectural choices that drive the results.

Head-to-Head Benchmarks

The most striking result is the sheer sweep of the Intel Xeon 6357P’s victory. In the Passmark suite, the Intel part wins every single test, with margins ranging from a modest 10.6% in single-threaded workloads to a massive 51.5% in physics simulation. The data shows no territory where the AMD Ryzen AI 5 PRO 440 manages to close the gap, making this a one-sided comparison in raw compute terms.

Starting with single-thread performance, the Xeon 6357P scores 4233 in Passmark single-thread versus the AMD’s 3785, a 10.6% advantage. This is the narrowest margin in the entire comparison, suggesting that the Ryzen AI 5 PRO 440’s Zen 5 architecture is highly competitive on a per-core basis, despite its lower clock speeds. The Xeon’s 5.40 GHz boost clock versus the AMD’s 4.80 GHz explains much of this edge, but the Ryzen’s efficiency allows it to stay within striking distance.

The gap widens dramatically in multi-threaded workloads. The Passmark multithread test shows the Xeon scoring 30759 against the AMD’s 21054, a 31.6% deficit for the Ryzen. This aligns with the core-count difference: 8 cores and 16 threads versus 6 cores and 12 threads. However, the scaling is not purely linear, as the Xeon’s 2 MB per-core L2 cache and 24 MB shared L3 provide a substantial memory hierarchy advantage over the AMD’s 1 MB per-core L2 and 8 MB L3.

The most lopsided results appear in specialized compute tasks. The Passmark physics test delivers a 51.5% advantage to the Xeon (2305 versus 1119), the largest margin in the entire dataset. Similarly, the find-prime-numbers test shows a 48.3% gap (149 versus 77), indicating that the Xeon’s higher cores and clocks translate into superior integer throughput. Floating-point math follows suit with a 42.3% gap (74460 versus 42934), while integer math shows a 32.2% difference (97375 versus 65991).

Data-centric workloads paint a consistent picture. The Xeon leads data compression by 27.5% (353521 versus 256420), data encryption by 32.2% (18324 versus 12418), and random string sorting by 23.2% (35495 versus 27252). Extended instructions show a 24.6% gap (24490 versus 18456). These results indicate that the Xeon’s architectural advantages—larger caches, higher clocks, and more cores—compound across varied workload types.

Contextualizing against nearest rivals, the AMD Ryzen AI 5 PRO 440’s average benchmark score of 41208 places it nearly identical to the Intel Core Ultra 7 356H (41215, 0% delta) and slightly above the Intel Core Ultra X7 358H (40967, 0.6% delta). The Intel Xeon 6357P’s average score of 40630 sits close to the Intel Core 5 223PE (40585, 0.1% delta) and below the AMD Ryzen AI 5 PRO 435G (40718, -0.2% delta). Both CPUs occupy the 87th percentile among all CPUs, indicating they are both high-performance parts, but the Xeon’s raw compute advantage is substantial within this tier.

The Verdict

The data is unambiguous: the Intel Xeon 6357P is the superior performer in every measured benchmark. For workloads that demand raw compute—physics simulation, floating-point math, prime number generation, data encryption—the Xeon’s 8 cores, 16 threads, and 5.40 GHz boost clock deliver margins of 23% to 51% over the AMD Ryzen AI 5 PRO 440. The 31.6% multithread advantage makes the Xeon the clear choice for multi-threaded server or workstation tasks.

However, the AMD Ryzen AI 5 PRO 440 is not without merit. Its 28W TDP versus the Xeon’s 80W TDP indicates a dramatically lower thermal envelope, making it suitable for mobile or compact systems where power and cooling are constrained. The AMD’s single-thread deficit of only 10.6% shows that Zen 5’s architecture is highly efficient, and its integrated Radeon 840M graphics provide a feature the Xeon lacks entirely. The AMD also offers a 4nm process node versus Intel’s 10nm, which explains its efficiency advantage.

Who should pick which? The Intel Xeon 6357P is the answer for anyone prioritizing maximum performance in compute-heavy, multi-threaded workloads, regardless of power consumption. The AMD Ryzen AI 5 PRO 440 is the choice for mobile professional laptops or compact workstations where the 28W power envelope and integrated graphics are decisive, and where the 10-30% performance deficit is an acceptable trade-off for portability and lower thermal output. The AMD’s 87th percentile ranking confirms it is still a high-performing part, but the Xeon’s identical percentile with superior raw scores makes it the performance leader in this pairing.

Specification Differences

The two processors differ fundamentally across their core specifications. The AMD Ryzen AI 5 PRO 440 offers 6 cores and 12 threads, while the Intel Xeon 6357P provides 8 cores and 16 threads, giving the Intel part a 33% core advantage. Clock speeds differ significantly: the AMD has a 2.00 GHz base and 4.80 GHz boost, whereas the Intel has a higher 3.00 GHz base and 5.40 GHz boost. The TDP disparity is substantial, with the AMD at 28W versus the Intel at 80W, representing a 2.9x power consumption difference.

Cache hierarchies diverge notably. The AMD has 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3, while the Intel has 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. This gives the Intel a 2x L2 cache per core and a 3x L3 cache total. Memory support differs: the AMD supports DDR5 and LPDDR5X with a dual-channel bus and 89.6 GB/s bandwidth, while the Intel supports DDR4 and DDR5 with a dual-channel bus and no listed bandwidth figure. Both support ECC memory.

Platform connectivity varies: the AMD uses PCIe Gen 4 with 16 lanes (CPU only), while the Intel uses PCIe Gen 5 with 16 lanes (CPU only). The socket types differ, with the AMD on AMD Socket FP8 and the Intel on Intel Socket 1700. The AMD includes integrated Radeon 840M graphics, while the Intel has no integrated graphics. The AMD has a die size of 195 mm² versus the Intel’s 257 mm². The Intel carries a launch MSRP of $556, while the AMD has no listed launch MSRP.

Architecture Differences

The architectural divide is rooted in process technology and design goals. The AMD Ryzen AI 5 PRO 440 is built on TSMC’s 4nm process, while the Intel Xeon 6357P uses Intel’s 10nm node. This process advantage allows the AMD to achieve its 28W TDP while still providing competitive single-thread performance, though the Intel’s larger 257 mm² die enables more cores and cache.

The AMD uses the Zen 5 architecture, codenamed Gorgon Point, from the Ryzen AI PRO 400 generation (Zen 5 / Zen 5c). The Intel uses Raptor Lake architecture, codenamed Raptor Lake-R, from the Xeon 6 (Raptor Lake Refresh) generation. These are fundamentally different designs: Zen 5 is optimized for efficiency and mobile use, while Raptor Lake-R is a refresh of Intel’s hybrid architecture tuned for server/workstation workloads.

Cache architecture reflects these design goals. The AMD’s 8 MB L3 cache is modest, suited to its lower core count and mobile power envelope. The Intel’s 24 MB shared L3 is 3x larger, providing ample data residency for 8 cores processing server workloads. Per-core L2 also differs: 1 MB for AMD versus 2 MB for Intel, further favoring the Intel in cache-sensitive tasks.

Feature sets diverge in integrated graphics and PCIe generation. The AMD includes Radeon 840M iGPU, enabling display output without a discrete GPU, while the Intel has no integrated graphics, requiring a separate GPU for any visual output. The Intel supports PCIe Gen 5, offering double the bandwidth of the AMD’s PCIe Gen 4, which is significant for high-throughput server peripherals. Both support ECC memory, but the AMD’s LPDDR5X support is unique to its mobile positioning, while the Intel’s DDR4 compatibility targets legacy server deployments. The Intel’s release date of February 2025 and launch MSRP of $556 position it as a current-generation server part, while the AMD’s 2026 release date and active production status indicate a newer mobile platform.
