AMD Ryzen 5 150 vs Intel Core Ultra X9 378H Comparison

Where Each One Wins

The recorded data presents an unusually one-sided picture. Across every head-to-head benchmark in the database, the Intel Core Ultra X9 378H secures the win. The AMD Ryzen 5 150 does not register a single victory in any of the eleven compared tests. This absolute sweep is rare, and it shapes the entire comparison.

The AMD Ryzen 5 150 still occupies a legitimate position in the mobile processor landscape. Its average benchmark score of 34881 places it in the 84th percentile of all CPUs tracked. That is a solid standing, and its nearest rivals in the database, such as the Intel Core i7-13800H (average score 34988, delta -0.3%) and the Intel Core i9-12900HX (average score 35003, delta -0.3%), show that the AMD part operates in demanding company. The data suggests that for workloads where the Ryzen 5 150 is sufficient, it performs at a level comparable to those established mobile and desktop processors.

The Intel Core Ultra X9 378H, however, operates in a different tier entirely. Its average benchmark score of 47468 puts it in the 89th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 9 PRO 5945 (average score 47527, delta -0.1%) and the Intel Core i7-13700KF (average score 47330, delta 0.3%). These are high-end desktop-class parts, which indicates that the Intel mobile processor is delivering performance that rivals desktop silicon.

The division of wins is unambiguous: the Intel part wins in data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithreaded workloads, physics calculations, random string sorting, and single-threaded performance. The AMD part wins nowhere. The use-case split therefore is not about which processor wins which task, but rather about whether the user needs the raw performance of the Intel part or can accept the lower performance ceiling of the AMD part.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 150 uses the Zen 3+ architecture, codenamed Rembrandt-R, fabricated on a 6 nm process at TSMC. The Intel Core Ultra X9 378H uses the Panther Lake codename, fabricated on a 3 nm process at Intel's own foundry. The process node difference, 6 nm versus 3 nm, is significant, and it appears in the efficiency and performance characteristics of both parts.

Core counts differ sharply. The AMD processor has 6 cores and 12 threads, while the Intel processor has 16 cores and 16 threads. This is a substantial difference in raw parallel resources. The Intel part has more than double the cores, though it does not use simultaneous multithreading, so its thread count equals its core count. The AMD part uses SMT, giving it 12 threads from 6 cores.

Cache hierarchies are also distinct. The AMD Ryzen 5 150 has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache. The Intel Core Ultra X9 378H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Intel part has substantially more L1 and L2 cache per core, and a slightly larger L3 pool.

Memory support differs in both type and bandwidth. The AMD part supports DDR5 memory on a dual-channel bus with a measured memory bandwidth of 76.8 GB/s. The Intel part supports LPDDR5X memory, also dual-channel, but with a memory bandwidth of 153.6 GB/s, exactly double the AMD figure. This doubling of memory bandwidth is a major architectural advantage for the Intel processor in bandwidth-sensitive workloads.

PCIe connectivity also differs. The AMD Ryzen 5 150 provides PCIe Gen 4 with 20 lanes from the CPU. The Intel Core Ultra X9 378H provides PCIe Gen 5 with only 4 lanes from the CPU. This is a trade-off: the Intel part uses a newer PCIe standard but with far fewer lanes. Integrated graphics differ as well, with the AMD part using Radeon 660M and the Intel part using Arc B390.

Head-to-Head Benchmarks

The head-to-head results show consistent and often massive Intel advantages. The largest gap appears in passmark find prime numbers, where the Intel Core Ultra X9 378H scores 357 against the AMD Ryzen 5 150's 47, a delta of -86.8%. That is a workload the Intel architecture handles with overwhelming superiority.

Floating point math shows a similarly large divide. The Intel part scores 114500, while the AMD part scores 35118, a delta of -69.3%. Physics calculations also favor Intel heavily: 3404 versus 806, a delta of -76.3%. These are computational workloads that rely on raw execution resources, and the Intel processor's 16 cores and higher boost clock of 5.00 GHz against the AMD's 4.55 GHz appear to be decisive.

Multithreaded performance follows the same pattern. The Intel part scores 38298 in passmark multithread, versus 17492 for the AMD part, a delta of -54.3%. Data compression shows a delta of -45.3% (386591 versus 211289), and random string sorting shows a delta of -49.9% (44648 versus 22382). These are all workloads that scale with core count and memory bandwidth, both of which favor the Intel part.

The smallest deltas are still substantial. Integer math shows a delta of -32.9% (92603 versus 62151). Single-threaded performance, often a strong point for AMD's Zen architectures, also favors Intel: 4453 versus 3155, a delta of -29.1%. Data encryption shows a delta of -55% (29840 versus 13425), and extended instructions show a delta of -53.1% (31315 versus 14675).

The data indicates that the Intel part is not merely faster in a few tests; it is faster in every measured category, often by margins exceeding 50%. The AMD part's best relative showing is in single-threaded and integer workloads, where the deltas are under 33%, but it still loses those tests.

Specification Differences

The specification table reveals several areas where the two processors diverge. The AMD Ryzen 5 150 has a base clock of 3.30 GHz, while the Intel Core Ultra X9 378H has a base clock of 2.00 GHz. The boost clocks reverse this relationship: the AMD part boosts to 4.55 GHz, while the Intel part boosts to 5.00 GHz. The Intel part therefore has a wider clock range and a higher ceiling.

Thermal design power differs notably. The AMD part has a TDP of 35 watts, while the Intel part has a TDP of 25 watts. The data shows that the Intel processor delivers substantially higher performance while being rated for a lower TDP, which suggests better efficiency per watt, though the database does not include direct power consumption measurements.

The socket types are different and incompatible. The AMD Ryzen 5 150 uses AMD Socket FP7, while the Intel Core Ultra X9 378H uses Intel BGA 2540. Neither processor has an unlocked multiplier, so overclocking is not an option for either. The AMD part has a known part number (100-000000990, FP7r2), while the Intel part's part number is listed as unknown.

Release dates differ by about six months. The AMD processor was released on 2025-09-30, while the Intel processor was released on 2026-04-03. Both are listed as active in production, and both target the mobile market segment. Neither supports ECC memory. The die size is listed only for the AMD part at 210 mm², while the Intel part's die size is not recorded in the database.
