AMD Ryzen 7 160 vs Intel Core Ultra X9 378H Comparison

The benchmark data separates these two mobile processors into distinct performance classes. The Intel Core Ultra X9 378H wins every recorded head-to-head test, often by decisive margins, while the AMD Ryzen 7 160 holds its own in specific integer workloads. The Intel part achieves a higher average benchmark score of 47468 compared to 37117 for the AMD processor, and it sits in the 89th percentile versus the 85th percentile for the Ryzen. This is not a close contest; it is a matchup where the Intel part demonstrates superiority across nearly all measured categories.

Where Each One Wins

The Intel Core Ultra X9 378H claims all 11 head-to-head benchmark victories, but the scale of those wins varies dramatically by workload type. The largest advantages appear in floating-point mathematics, where the Intel part scores 114500 against 6673 for the AMD Ryzen 7 160, a delta of 94.2 percent. This indicates a fundamental advantage in workloads that rely on heavy mathematical throughput, such as scientific simulations, rendering, and certain financial modeling tasks. The Intel processor also dominates prime number finding, scoring 357 versus 43, an 88 percent gap that reflects superior integer execution on certain algorithmic patterns.

The AMD Ryzen 7 160 does not win any recorded benchmark, but its closest relative performance appears in integer math. The Intel Core Ultra X9 378H scores 92603 versus 81370 for the AMD part, a delta of only 12.1 percent. This suggests that in purely integer-heavy operations, the Ryzen 7 160 is far more competitive than the overall score gap implies. The data shows that the AMD processor is not uniformly outclassed; it narrows the gap substantially in specific instruction patterns. However, the Intel part still leads, and the margin, while smaller, remains consistent.

Architecture Differences

The two processors use fundamentally different design philosophies. The AMD Ryzen 7 160 is built on a 6 nm process at TSMC, using the Zen 3+ architecture with the Rembrandt-R codename. It features 8 cores and 16 threads, a base clock of 2.70 GHz, and a boost clock of 4.75 GHz. The Intel Core Ultra X9 378H uses a 3 nm process at Intel foundry, based on the Panther Lake codename, and it packs 16 cores with 16 threads, meaning every core is a performance core with no hyper-threading. The Intel part has a lower base clock of 2.00 GHz but a higher boost clock of 5.00 GHz.

Cache hierarchies also diverge sharply. The AMD processor provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3. The Intel part provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel design allocates significantly more cache per core, which contributes to its single-thread advantage. The AMD part supports DDR5 memory with a dual-channel bus and 76.8 GB/s of bandwidth, while the Intel part uses LPDDR5X with a dual-channel bus and 153.6 GB/s, exactly double the bandwidth. The Intel processor also supports PCIe Gen 5 with 4 lanes, whereas the AMD part uses PCIe Gen 4 with 20 lanes.

The integrated graphics differ as well: the AMD Ryzen 7 160 includes a Radeon 680M, while the Intel Core Ultra X9 378H includes an Arc B390. The AMD part supports ECC memory, while the Intel part does not. The AMD processor is unlocked for overclocking, while the Intel part is not. The Intel part draws 25 W TDP compared to 28 W for the AMD chip, a modest difference that does not explain the large performance gap.

Head-to-Head Benchmarks

The most decisive Intel victory is in floating-point math. The Intel Core Ultra X9 378H scores 114500 versus 6673 for the AMD Ryzen 7 160, a 94.2 percent delta. This single result indicates a massive architectural advantage in FPU throughput, likely driven by the newer process node and wider execution resources. No other test comes close to this margin. Prime number finding shows an 88 percent delta, with Intel at 357 and AMD at 43. This pattern suggests that the Intel core can handle certain iterative integer workloads far more efficiently.

Multi-threaded performance heavily favors Intel. The Intel part scores 38298 in PassMark multithread against 12237 for the AMD processor, a 68 percent delta. This aligns with the core count difference: 16 physical cores versus 8 cores with simultaneous multithreading. The physics test shows a 76.7 percent delta, with Intel at 3404 and AMD at 793. This indicates that the Intel part handles physics simulation workloads, which often scale with core count and clock speed, much better. Data encryption shows a 48 percent delta, with Intel at 29840 versus 15520 for AMD. Extended instructions show a 48.4 percent delta, Intel at 31315 versus 16170.

Data compression favors Intel at 386591 versus 242634, a 37.2 percent delta. Random string sorting gives Intel 44648 versus 25981, a 41.8 percent delta. The smallest Intel advantage appears in integer math at 12.1 percent, with a score of 92603 versus 81370. Single-thread performance shows Intel at 4453 versus 3435 for AMD, a 22.9 percent delta. This single-thread gap is substantial and consistent with the higher boost clock of 5.00 GHz versus 4.75 GHz, plus the larger L1 and L2 caches per core.

The Verdict

The data directs a clear choice for users who need maximum performance across a broad range of workloads. The Intel Core Ultra X9 378H wins every single benchmark in the comparison, with particularly large margins in floating-point math, prime number finding, physics, and multi-threaded tests. Its 16 physical cores, 5.00 GHz boost clock, 3 nm process, and doubled memory bandwidth provide a comprehensive advantage. The 89th percentile ranking versus 85th for the AMD part confirms this is a higher-tier processor overall.

The AMD Ryzen 7 160 remains relevant only for workloads that are heavily integer-bound. Its 12.1 percent deficit in integer math is the closest result in the entire comparison, which indicates that it can handle general integer processing reasonably well. It also offers ECC memory support and an unlocked multiplier, which are features absent from the Intel part. However, these features do not compensate for the performance gap in the recorded benchmarks.

For a user prioritizing raw performance, especially in multi-threaded or floating-point intensive tasks, the Intel Core Ultra X9 378H is the only choice supported by the data. For a user who requires ECC memory or overclocking capability and can tolerate a slower processor, the AMD Ryzen 7 160 has specific merits. The benchmark results, however, show no scenario where the AMD part outperforms the Intel part.
