AMD Ryzen AI Embedded P164 vs Intel Xeon 634 Comparison

The Intel Xeon 634 and AMD Ryzen AI Embedded P164 sit at opposite ends of the computing spectrum, yet their average benchmark scores are nearly identical. The Xeon 634 posts an average score of 52,974, while the Ryzen AI P164 achieves 52,901, a difference of just 0.1%. Both processors land in the 91st percentile of all CPUs, placing them in the same performance tier overall. However, a closer look at the individual benchmarks reveals that this statistical tie masks fundamentally different strengths. The Xeon 634 wins 9 of the 11 head-to-head comparisons, while the Ryzen AI P164 wins only 2, but those 2 victories are decisive in single-threaded workloads.

Head-to-Head Benchmarks

The Intel Xeon 634 dominates the multi-threaded and compute-intensive workloads with substantial margins. In the PassMark data compression test, the Xeon scores 477,924 against the Ryzen's 327,891, a 45.8% advantage. Data encryption shows a similar pattern, with the Xeon at 23,451 and the Ryzen at 16,055, marking a 46.1% lead. The most lopsided result comes from the find prime numbers test, where the Xeon scores 196 versus the Ryzen's 71, delivering a massive 176.1% advantage. These results indicate that the Xeon's 12 cores and 24 threads provide a significant throughput advantage over the Ryzen's 8 cores and 16 threads in parallel workloads.

Floating-point math performance follows the same trend. The Xeon scores 93,564, which is 67.7% higher than the Ryzen's 55,799. Integer math shows a narrower but still decisive gap, with the Xeon at 117,664 and the Ryzen at 87,940, a 33.8% difference. Extended instructions performance favors the Xeon by 58.4%, with scores of 38,320 against 24,193. The multithread benchmark gives the Xeon a 45.2% edge, scoring 37,589 versus 25,889. Physics calculations show an 86% advantage for the Xeon, with scores of 2,250 and 1,210 respectively. Random string sorting completes the Intel sweep of the throughput tests, with the Xeon scoring 47,016 versus the Ryzen's 34,801, a 35.1% lead.

The AMD Ryzen AI Embedded P164 takes the single-threaded crown decisively. In the PassMark single-thread test, the Ryzen scores 4,029 against the Xeon's 3,567, an 11.5% advantage. This is the only category where the Ryzen leads, but it does so in both the `single_thread` and `singlethread` entries, which report identical scores of 4,029 for the Ryzen and 3,567 for the Xeon. The higher boost clock of 5.00 GHz on the Ryzen, compared to 4.60 GHz on the Xeon, contributes to this single-core superiority. The data shows that for workloads that rely on a single thread, the Ryzen is the clear choice, but for everything else, the Xeon's additional cores and threads provide a substantial performance buffer.

The Verdict

The benchmark data points to a clear divide. The Intel Xeon 634 is the superior choice for multi-threaded workloads, data compression, encryption, and any task that scales with core count. Its 45.8% advantage in data compression and 46.1% lead in encryption make it the obvious pick for server and workstation environments where such workloads are common. The Xeon's 176.1% advantage in prime number finding further cements its position for computational mathematics and scientific computing. With a 45.2% lead in the multithread benchmark, the Xeon is the stronger all-around performer for parallel processing.

The AMD Ryzen AI Embedded P164 is the better option for single-threaded performance, offering an 11.5% improvement over the Xeon in that specific metric. Its 5.00 GHz boost clock, higher than the Xeon's 4.60 GHz, drives this advantage. For workloads that are latency-sensitive or rely on a single thread, the Ryzen delivers better responsiveness. The Ryzen also comes with integrated Radeon 880M graphics, which the Xeon lacks, making it a more complete package for systems that need graphical output without a discrete GPU. The Ryzen's significantly lower TDP of 28 watts, compared to the Xeon's 150 watts, also positions it for power-constrained environments, though the data does not directly measure power efficiency.

For users prioritizing raw multi-core throughput, the Xeon 634 is the data-backed choice. For those needing maximum single-core speed and integrated graphics, the Ryzen AI P164 stands out. The average scores are nearly identical, but the workload profile determines the winner.

Architecture Differences

The two processors come from different architectural lineages. The Intel Xeon 634 is built on the Granite Rapids architecture, part of the Xeon 600 (Granite Rapids-WS) generation, and manufactured on a 5 nm process by Intel. Its die size is 598 mm². The AMD Ryzen AI Embedded P164 uses the Gorgon Point codename, based on the Ryzen AI Embedded (Zen 5 / Zen 5c) generation, and is manufactured on a 4 nm process by TSMC. Its die size is 233 mm². The smaller process node allows the Ryzen to achieve higher clock speeds despite lower power consumption.

Cache configurations differ markedly. The Xeon 634 provides 112 KB of L1 cache per core, 2 MB of L2 cache per core, and a substantial 48 MB of shared L3 cache. The Ryzen AI P164 offers 80 KB of L1 cache per core, 1 MB of L2 cache per core, and only 8 MB of L3 cache. The Xeon's 48 MB L3 cache is a significant advantage for workloads that benefit from large shared caches, while the Ryzen's smaller cache reflects its mobile-oriented design.

Memory support also diverges. The Xeon 634 supports DDR5 memory over a quad-channel bus, providing a memory bandwidth of 204.8 GB/s. The Ryzen AI P164 supports both DDR5 and LPDDR5X over a dual-channel bus, with a memory bandwidth of 89.6 GB/s. The Xeon's quad-channel configuration delivers more than twice the memory bandwidth, which is critical for memory-intensive server workloads. Both processors support ECC memory, ensuring data integrity in enterprise applications.

PCIe capabilities differ significantly. The Xeon 634 offers Gen 5 with 80 lanes (CPU only), while the Ryzen AI P164 provides Gen 4 with 16 lanes (CPU only). The Xeon's Gen 5 support and 80-lane count make it suitable for high-bandwidth expansion, including multiple GPUs or NVMe storage arrays. The Ryzen's Gen 4 and 16 lanes are adequate for mobile or embedded systems but do not match the Xeon's expansion capacity.

Specification Differences

The core and thread counts are the most obvious differentiators. The Intel Xeon 634 has 12 cores and 24 threads, while the AMD Ryzen AI Embedded P164 has 8 cores and 16 threads. The Xeon's base clock is 2.70 GHz, compared to the Ryzen's 2.00 GHz. However, the Ryzen's boost clock is 5.00 GHz, exceeding the Xeon's 4.60 GHz. The TDP values show a stark contrast: the Xeon draws 150 watts, while the Ryzen draws only 28 watts.

Socket compatibility separates the two entirely. The Xeon 634 uses Intel Socket 4710, while the Ryzen AI P164 uses AMD Socket FP8. The Xeon has an unlocked multiplier, whereas the Ryzen does not. The market segments differ as well, with the Xeon targeting Server/Workstation and the Ryzen targeting Mobile. The Xeon has an active production status and a launch MSRP of $499, while the Ryzen also has an active production status but no launch MSRP listed. The integrated graphics presence also differs, with the Ryzen featuring Radeon 880M and the Xeon having none.

The release dates are close, with the Xeon launching on 2026-02-01 and the Ryzen on 2026-03-08. The part numbers differ, with the Xeon listed as SA2DL and the Ryzen marked as unknown. These specification differences underscore the distinct design philosophies: the Xeon is a high-power, high-throughput workstation processor, while the Ryzen is a low-power, mobile-focused chip with integrated graphics and a higher boost clock.
