AMD Ryzen 5 150 vs Intel Core Ultra X7 358H Comparison

Head-to-Head Benchmarks

The recorded data presents a one-sided contest. Across all eleven shared PassMark workloads, the Intel Core Ultra X7 358H posts the higher score, leaving the AMD Ryzen 5 150 without a single head-to-head win. The margins, however, vary considerably by workload type, which reveals distinct strengths and weaknesses for each processor.

The largest gap appears in the prime number search test. AMD scores 47, while Intel reaches 337, a delta of -86.1 percent. This is an extreme outlier, suggesting Intel's architecture handles this specific integer workload with exceptional efficiency. Floating-point math also shows a massive divide: AMD scores 35,118 versus Intel's 103,842, a -66.2 percent difference. Physics simulation follows a similar pattern, with AMD at 806 and Intel at 3,021, a -73.3 percent gap. These three results indicate that Intel has a commanding lead in mathematically intensive tasks.

The gap narrows in integer math, where AMD scores 62,151 and Intel scores 83,147, a -25.3 percent delta. Data encryption shows AMD at 13,425 and Intel at 26,046, a -48.5 percent difference. Extended instructions favor Intel 27,274 to 14,675, a -46.2 percent gap. Random string sorting sees Intel ahead 40,357 to 22,382, a -44.5 percent margin. Data compression shows Intel at 332,508 versus AMD's 211,289, a -36.5 percent delta.

Single-thread performance is the closest contest. AMD scores 3,155, Intel scores 4,124, a -23.5 percent difference. This is still a decisive win for Intel, but it is the smallest relative gap in the entire suite. Multithread performance shows Intel at 33,802 versus AMD's 17,492, a -48.3 percent delta, reinforcing that Intel's advantage scales with parallelism.

The overall average benchmark score reflects this dominance: AMD sits at 34,881, while Intel reaches 40,967. The percentile rankings place AMD in the 84th percentile of all CPUs, with Intel in the 87th. The nearest rival data adds context. AMD's closest competitor is the Intel Xeon 6349P, which scores 34,890, a negligible 0 percent delta. Intel's nearest rival is the AMD Ryzen AI 5 PRO 435G, scoring 40,718, a +0.6 percent delta in Intel's favor. This means both processors sit comfortably within their respective performance tiers, but those tiers are distinctly different.

Architecture Differences

The two chips take fundamentally different design approaches. AMD uses a 6-core, 12-thread configuration based on the Zen 3+ architecture, codenamed Rembrandt-R. This is a 6 nm part fabricated by TSMC. Intel counters with a 16-core, 16-thread design on the Panther Lake codename, using a 3 nm process built by Intel's own foundry. The core count difference is stark: Intel has 10 more physical cores, though it lacks simultaneous multithreading, so thread counts are 12 for AMD versus 16 for Intel.

Cache hierarchies differ significantly. AMD allocates 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. Intel allocates 192 KB of L1 per core, a substantial 3 MB of L2 per core, and 18 MB of shared L3. The larger per-core L2 cache on Intel likely contributes to its single-thread advantage, as more data can reside closer to the execution units.

Clock speeds tell a nuanced story. AMD has a base clock of 3.30 GHz and a boost clock of 4.55 GHz. Intel starts lower at 1.90 GHz base but boosts higher to 4.80 GHz. The lower base clock on Intel is offset by the higher boost ceiling and the sheer core count. Package power draws differ as well: AMD is rated at 35 W TDP, Intel at 25 W TDP. This is notable because Intel delivers higher performance while maintaining a lower thermal design point.

Memory support diverges. AMD uses DDR5 with dual-channel access and 76.8 GB/s bandwidth. Intel uses LPDDR5X, also dual-channel, but with 153.6 GB/s bandwidth, exactly double. This memory bandwidth advantage likely fuels Intel's dominance in data compression and encryption workloads, which are often memory-bound. PCIe connectivity also differs: AMD provides Gen 4 with 20 lanes, Intel provides Gen 5 with 4 lanes. The lane count is lower on Intel, but the per-lane bandwidth is higher.

Integrated graphics distinguish the pair. AMD ships the Radeon 660M, while Intel includes the Arc B390. Both are mobile-oriented parts, and the data does not include graphics benchmarks, so no direct comparison is possible. Socket and platform details also differ: AMD uses Socket FP7, Intel uses BGA 2540. Release dates place AMD at September 30, 2025, and Intel at January 4, 2026, a gap of just over three months.

The Verdict

The data points to a clear performance hierarchy. Intel wins every benchmark in the shared suite, with margins ranging from -23.5 percent to -86.1 percent. The average benchmark score gap is 6,086 points, or roughly 17.4 percent in Intel's favor. The percentile ranking confirms this: Intel sits in the 87th percentile, AMD in the 84th.

For users prioritizing raw compute throughput, the Intel Core Ultra X7 358H is the stronger choice based on every recorded metric. Its advantages in floating-point math, physics, and prime number finding are particularly pronounced, suggesting a design optimized for scientific and analytical workloads. The higher single-thread score of 4,124 versus 3,155 also indicates better responsiveness in lightly threaded tasks.

The AMD Ryzen 5 150 is not without merit, but its strengths are relative rather than absolute. It achieves its scores with fewer cores, 6 versus 16, and a higher TDP, 35 W versus 25 W. This means AMD uses more power per unit of performance. The smaller performance gap in single-thread tests, -23.5 percent, suggests that AMD's Zen 3+ cores are competitive on a per-core basis, but Intel's additional cores create an insurmountable aggregate lead.

The nearest rival data positions each chip differently. AMD's closest competitor, the Intel Xeon 6349P, has a virtually identical average score, indicating that the Ryzen 5 150 is well-matched to that segment. Intel's closest rival, the AMD Ryzen AI 5 PRO 435G, trails by only 0.6 percent, showing the Core Ultra X7 358H is at the top of its immediate competitive cluster. The data does not support any scenario where AMD wins a benchmark, so the verdict is straightforward: Intel dominates this matchup.

Where Each One Wins

Intel wins every measured workload, so a use-case split requires interpreting which tasks AMD comes closest in and which it falls furthest behind. For integer math, AMD's score of 62,151 is within 25.3 percent of Intel's 83,147, the closest relative margin outside single-thread tests. This suggests AMD is least disadvantaged in general arithmetic and data manipulation tasks. Single-thread performance, with a -23.5 percent gap, is the other relatively competitive area, indicating AMD can handle lightly threaded applications with less penalty.

For data compression, AMD scores 211,289 versus Intel's 332,508, a -36.5 percent gap. This is a moderate deficit, but still substantial. Random string sorting shows a -44.5 percent delta, meaning AMD falls further behind in sorting and organizing workloads. Extended instructions, encryption, and multithread tests all show gaps between -46.2 percent and -48.5 percent, placing AMD at roughly half of Intel's performance in these areas.

The most severe deficits appear in floating-point math, physics, and prime number finding, with gaps of -66.2 percent, -73.3 percent, and -86.1 percent respectively. These workloads rely heavily on high-throughput arithmetic pipelines, where Intel's 16 cores and doubled memory bandwidth provide an overwhelming advantage. AMD's 6 cores cannot compensate, regardless of clock speed.

In practical terms, Intel is the appropriate choice for scientific computing, simulation, data analysis, and any workload with heavy mathematical content. AMD is less disadvantaged in general office productivity, light integer-heavy applications, and single-threaded legacy software, though it still trails in every case. The data does not reveal any workload where AMD wins, so any selection of AMD must rest on factors outside the recorded benchmarks, such as platform ecosystem or integrated graphics capabilities, which are not compared here.
