AMD Ryzen AI Embedded P185 vs Intel Xeon Gold 6338T Comparison

The AMD Ryzen AI Embedded P185 and Intel Xeon Gold 6338T occupy different corners of the processor market, and the benchmark data reflects that split clearly. The AMD part wins 4 of the 11 direct comparisons, while the Intel server chip takes 7, but the nature of those victories matters more than the raw count. The AMD Ryzen AI Embedded P185 is a low-power, high-frequency mobile part with a strong single-thread presence, while the Intel Xeon Gold 6338T is a high-core-count server processor built for sustained throughput. The recorded data shows that neither processor is a universal winner, and the correct choice depends entirely on the workload.

Where Each One Wins

The Intel Xeon Gold 6338T dominates the throughput-oriented categories. It wins data compression by 32.9%, scoring 557816 against the AMD part's 374429. That is a massive gap in a workload that scales with core count and memory bandwidth. The Intel chip also leads in data encryption by 20.5%, with scores of 24677 versus 19612, and in extended instructions by 38.7%, posting 43292 against 26544. These are all tasks that benefit from the Xeon's 24 cores and 48 threads. The same pattern appears in floating-point math, where the Xeon scores 90584 versus 70587, a 22.1% advantage, and in integer math, where it leads by 22.6% with 152275 against 117832. The multithread score tells the same story: the Xeon wins by 11.1% with 35801 versus 31817. The largest Intel win of all is in random string sorting, where it beats the AMD part by 39%, scoring 66495 against 40557. These results all point to the same conclusion: the Xeon Gold 6338T is the choice for heavy parallel processing.

The AMD Ryzen AI Embedded P185 wins the categories that depend on clock speed and per-core efficiency. Its single-thread score of 3977 is 69.4% higher than the Xeon's 2348, which is the largest delta in either direction across all 11 benchmarks. The physics test also goes to the AMD part, with a score of 1772 versus 1160, a 52.8% advantage. That is a notable result because physics simulations often rely on a mix of single-thread performance and cache behavior. The AMD chip also wins the find prime numbers test by 9.3%, scoring 129 against 118. These three wins show that the Ryzen AI Embedded P185 is substantially faster in lightly threaded tasks. It also carries an integrated Radeon 890M GPU, which gives it a capability the Xeon entirely lacks, though the benchmark data does not directly measure graphics performance.

The Verdict

Choose the Intel Xeon Gold 6338T if the workload is any form of high-volume data processing, compression, encryption, or math that can spread across many cores. The data shows it is ahead in 7 of 11 comparisons, and its wins include the largest absolute margins. The Xeon's 204.8 GB/s memory bandwidth, enabled by eight-channel DDR4, supports its throughput advantage. It also has 64 PCIe Gen 4 lanes, making it suitable for systems with many expansion devices. The AMD part cannot match this level of parallel throughput, and the 11.1% multithread deficit is the closest it gets in the heavy categories.

Choose the AMD Ryzen AI Embedded P185 for single-threaded applications, interactive workloads, or any task where a 5.10 GHz boost clock matters more than core count. Its 69.4% single-thread lead is decisive, and the 52.8% physics win shows that some specialized workloads strongly prefer the AMD architecture. The 28 W TDP is also a critical differentiator, suggesting the AMD part can operate in thermally constrained environments where the 165 W Xeon would not fit. The integrated Radeon 890M adds graphics capability without a discrete GPU, which is a practical advantage for compact embedded systems. The Ryzen AI Embedded P185 is not a server replacement, but it is the faster processor for the workloads where it wins.

Head-to-Head Benchmarks

The largest single benchmark win belongs to the AMD Ryzen AI Embedded P185 in the single-thread test. It scores 3977 against the Xeon's 2348, a 69.4% advantage. This is not a marginal difference; it is a generational gap in per-core performance. The AMD part's Zen 5 architecture on a 4 nm process clearly delivers far higher instructions per clock than the Intel Ice Lake design on 10 nm. The same test appears twice in the data with identical scores, confirming the result is stable.

The Intel Xeon Gold 6338T's biggest win is in random string sorting, where it leads by 39%. With a score of 66495 against 40557, the Xeon demonstrates that its combination of 24 cores, 48 threads, and 36 MB of shared L3 cache is highly effective for sorting workloads. Data compression follows closely behind, with the Xeon ahead by 32.9%. The extended instructions test shows a 38.7% Intel advantage, indicating that the Xeon's larger core count provides a significant edge in AVX-style workloads.

The physics test is the most surprising result in the comparison. The AMD part wins by 52.8%, scoring 1772 against 1160. This is a massive margin in a test that often favors higher core counts. The explanation likely lies in the AMD part's 5.10 GHz boost clock and its per-core cache configuration, which includes 80 KB of L1 and 1 MB of L2 per core. The Xeon's lower 3.40 GHz boost clock cannot compensate for the AMD part's efficiency in this specific test.

The floating-point and integer math tests both favor the Xeon by similar margins: 22.1% and 22.6% respectively. These are moderate wins that reflect the Xeon's 24-core advantage, but they are not as large as the sorting or compression gaps. The multithread score shows the Xeon ahead by 11.1%, which is the smallest Intel win in the throughput categories. This suggests that the AMD part's high clock speed helps it in mixed workloads, even when outnumbered by the Xeon's cores.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Embedded P185 uses the Gorgon Point codename with a Zen 5 / Zen 5c generation architecture, built on a 4 nm process at TSMC. The die size is 233 mm². The Intel Xeon Gold 6338T uses the Ice Lake-SP codename with an Ice Lake architecture, built on a 10 nm process at Intel. These process differences explain much of the performance gap: the AMD part's smaller node allows higher clock speeds at much lower power.

Cache configurations also differ meaningfully. The AMD part has 80 KB of L1 per core and 1 MB of L2 per core, with 16 MB of L3 cache. The Intel Xeon has 64 KB of L1 per core and 1 MB of L2 per core, but its L3 cache is 36 MB shared across all cores. The larger L3 cache on the Xeon helps in multi-threaded workloads that share data, while the AMD part's higher per-core L1 cache supports its single-thread advantage.

Memory support is another major distinction. The AMD Ryzen AI Embedded P185 supports DDR5 and LPDDR5X in a dual-channel configuration, delivering 89.6 GB/s of bandwidth. The Intel Xeon Gold 6338T supports only DDR4, but in an eight-channel configuration that delivers 204.8 GB/s. That is more than double the AMD part's bandwidth, which directly explains the Xeon's dominance in data compression and random string sorting. Both processors support ECC memory, which is essential for embedded and server reliability.

The PCIe capabilities also differ. The AMD part provides Gen 4 with 16 lanes, while the Intel Xeon provides Gen 4 with 64 lanes. This makes the Xeon far more suitable for systems with many NVMe drives or GPUs. The AMD part's lane count is adequate for a mobile or embedded design, but not for a full server expansion environment.

Specification Differences

The core and thread counts are the most obvious difference: the Intel Xeon Gold 6338T has 24 cores and 48 threads, while the AMD Ryzen AI Embedded P185 has 12 cores and 24 threads. The base clocks are close, with the Xeon at 2.10 GHz and the AMD part at 2.00 GHz, but the boost clocks diverge sharply. The AMD part reaches 5.10 GHz, while the Xeon tops out at 3.40 GHz. This 1.70 GHz difference explains the AMD part's single-thread dominance.

The thermal design power is another major differentiator. The AMD Ryzen AI Embedded P185 has a TDP of 28 W, while the Intel Xeon Gold 6338T has a TDP of 165 W. That is a nearly six-fold difference in power draw, making the AMD part suitable for fanless or low-power embedded designs. The Xeon requires substantial cooling and power delivery, typical of server environments.

Socket compatibility is entirely different: the AMD part uses AMD Socket FP8, while the Intel Xeon uses Intel Socket 4189. There is no upgrade path between them. The memory support differs as well, with the AMD part supporting DDR5 and LPDDR5X, while the Xeon supports DDR4. The memory bus is dual-channel on the AMD part and eight-channel on the Xeon, with corresponding bandwidth figures of 89.6 GB/s and 204.8 GB/s.

The AMD part includes integrated Radeon 890M graphics, while the Intel Xeon has no integrated graphics. The AMD part also lists a market segment of Mobile, while the Xeon is classified as Server/Workstation. Both processors are currently in Active production status. The release dates differ by nearly five years, with the Xeon launching on April 5, 2021, and the AMD part launching on February 28, 2026. Neither processor has a multiplier unlock, so overclocking is not supported on either platform.
