AMD Ryzen 7 170 vs Intel Core Ultra 9 386H Comparison

The AMD Ryzen 7 170 and Intel Core Ultra 9 386H are both mobile processors that land in the 88th percentile of all CPUs tested, yet their benchmark profiles could not be more different. The data shows a complete sweep in the head-to-head comparisons, with the Intel part winning all 11 recorded tests. However, the margin of victory varies wildly by workload, ranging from a modest 8.6% lead in integer math to a staggering 85.6% advantage in prime number finding. This makes the choice between them less about overall capability and more about identifying which specific performance characteristics matter most for your intended use case.

Head-to-Head Benchmarks

The Intel Core Ultra 9 386H dominates the PassMark suite, but the size of that dominance tells the real story. In integer math, the Intel chip scores 87,284 against the AMD’s 79,738, a relatively tight 8.6% gap. This suggests that for basic arithmetic-heavy tasks, the two are closer than the overall results imply. The gap widens significantly in data compression, where Intel’s 352,365 score beats AMD’s 265,920 by 24.5%. This is a substantial lead, but not a blowout.

The extreme performance differences appear in more specialized workloads. Floating point math sees Intel at 108,527 versus AMD’s 44,979, a 58.6% deficit for the Ryzen part. The physics test is even more lopsided, with Intel scoring 3,028 against AMD’s 890, a 70.6% difference. The single largest margin is in prime number generation, where Intel’s 341 score dwarfs AMD’s 49, representing an 85.6% gap. This pattern suggests that the Intel processor has a massive advantage in workloads that leverage advanced vector instructions or high-throughput parallel execution.

The multi-threaded results reinforce this trend. Intel scores 35,399 in the multi-thread test, compared to AMD’s 20,760, a 41.4% lead. The data encryption test shows Intel ahead by 40.8% (27,150 vs 16,078), while extended instructions see a 37.9% advantage (29,138 vs 18,107). Even random string sorting, which often favors cache-heavy designs, goes to Intel by 34% (42,135 vs 27,804). The single-thread test shows Intel winning 4,218 to 3,128, a 25.8% advantage. AMD does not secure a single win in any recorded benchmark, making this a clean sweep for Intel.

Where Each One Wins

Based strictly on the benchmark data, the Intel Core Ultra 9 386H wins in every measurable category. There is no workload in the PassMark suite where the AMD Ryzen 7 170 comes out ahead. The closest contest is integer math, where the AMD chip is only 8.6% behind, suggesting that scenarios involving basic arithmetic and general logic operations will show the smallest performance gap between the two.

For users prioritizing floating point performance, physics simulations, or prime number calculations, the Intel part is unequivocally the stronger choice. The 70.6% and 85.6% margins in physics and prime numbers, respectively, indicate that the Intel architecture is far better suited to scientific computing and mathematical modeling. Similarly, the 58.6% lead in floating point math means that 3D rendering, scientific simulations, and any workload relying on non-integer calculations will see dramatic benefits from the Intel processor.

The AMD Ryzen 7 170 does not win any category, so it cannot be recommended for a specific use case based on performance head-to-head. However, the smaller margins in integer math and data compression mean that for general productivity tasks like spreadsheet calculations or file archiving, the user experience difference will be less pronounced than in math-intensive workloads.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 170 uses the Zen 3+ architecture (codenamed Rembrandt-R) on a 6nm TSMC process, while the Intel Core Ultra 9 386H employs the Panther Lake architecture on Intel’s 3nm process. The Intel part belongs to the Core Ultra Series 3 and uses the Panther Lake-H generation, whereas the AMD chip is part of the Ryzen 7 series based on Zen 3+.

Core counts differ substantially: the Intel processor has 16 cores and 16 threads, while the AMD has 8 cores and 16 threads via simultaneous multithreading. This means the Intel chip doubles the physical core count but does not use additional threads, while the AMD relies on SMT to reach 16 threads. The cache hierarchy also differs. Intel has 192 KB of L1 per core and 2.5 MB of L2 per core, compared to AMD’s 64 KB L1 and 512 KB L2 per core. The L3 cache is 18 MB shared on Intel versus 16 MB shared on AMD.

The process node difference is significant: 3nm for Intel versus 6nm for AMD. This likely contributes to the Intel chip’s higher boost clock of 4.90 GHz versus AMD’s 4.75 GHz, despite the Intel part having a much lower base clock of 2.10 GHz compared to AMD’s 3.20 GHz. The thermal design power also differs, with Intel rated at 25W and AMD at 35W, which is counterintuitive given Intel’s higher performance. Memory support shows Intel supporting both DDR5 and LPDDR5X, while AMD only lists DDR5. Memory bandwidth is higher on Intel at 115.2 GB/s versus AMD’s 76.8 GB/s. Intel supports PCIe Gen 5 with 12 lanes, while AMD uses PCIe Gen 4 with 20 lanes. Intel’s integrated graphics is Intel Xe3 Graphics, while AMD uses Radeon 680M. Only AMD supports ECC memory.

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 9 386H is the superior processor in every recorded test. With an average benchmark score of 43,210 versus AMD’s 43,689, the overall averages are nearly identical, but the head-to-head results show Intel winning by margins from 8.6% to 85.6%. The Intel chip’s 16 physical cores, higher boost clock, and larger caches translate directly into performance dominance across the board.

The AMD Ryzen 7 170 does offer advantages in specific areas that are not reflected in the PassMark benchmarks. It supports ECC memory, which is critical for data integrity in professional environments. It also uses a socket (AMD Socket FP7) that may be more familiar to AMD users, and its 20 PCIe Gen 4 lanes could be preferable for certain expansion configurations compared to Intel’s 12 Gen 5 lanes. The lower base clock and higher TDP of the AMD chip suggest it is tuned differently, but the actual performance results do not favor it.

For anyone choosing between these two for a mobile workstation or high-performance laptop, the Intel Core Ultra 9 386H is the clear pick based on performance data. The only reasons to choose the AMD Ryzen 7 170 would be the need for ECC memory support or a preference for the AMD platform, as the performance gap cannot be justified by any benchmark result. The Intel part is faster in every measurable way, often by massive margins, and its lower TDP of 25W makes it a more efficient choice on paper as well. For the vast majority of users, the Intel Core Ultra 9 386H is the definitive choice.
