AMD Ryzen 7 PRO 5755G vs Intel Core Ultra 9 386H Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the Intel Core Ultra 9 386H, which claims 10 of the 11 head-to-head benchmark wins. The AMD Ryzen 7 PRO 5755G manages a single win, but the margin analysis reveals a clear performance stratification between these two processors.

The largest gap appears in the PassMark find prime numbers test. The Intel part scores 341, while the AMD chip records 58, a delta of -83%. This is an exceptional spread, indicating a fundamental difference in how the two architectures handle this particular integer workload. The physics test also shows a massive divide, with Intel at 3028 versus AMD at 1022, a -66.2% delta. Floating point math follows a similar pattern: Intel delivers 108527 against AMD’s 50778, a -53.2% deficit for the Ryzen part.

In multithreaded performance, the Core Ultra 9 386H posts 35399, which is 32.6% ahead of the Ryzen 7 PRO 5755G’s 23858. This is a substantial lead, likely reflecting the 16-core versus 8-core configuration. The data encryption workload shows a 28.4% Intel advantage (27150 versus 19450), and extended instructions favor Intel by 29.7% (29138 versus 20487). Data compression sees Intel at 352365 versus AMD at 295730, a 16.1% edge. Random string sorting is closer but still favors Intel: 42135 versus 32771, a 22.2% delta.

Single-thread performance, a critical metric for everyday responsiveness, is firmly in Intel’s corner. The Core Ultra 9 386H scores 4218 in both passmark_single_thread and passmark_singlethread, while the Ryzen 7 PRO 5755G records 3366. That is a 20.2% advantage for Intel. The data shows that the Intel chip is not just winning on core count; it also wins on per-thread efficiency in this comparison.

The sole AMD victory is in integer math. The Ryzen 7 PRO 5755G scores 90270, edging out the Core Ultra 9 386H’s 87284, a 3.4% delta. This is a narrow win, but it demonstrates that AMD’s Zen 3 core design retains a specific strength in pure integer arithmetic operations. However, this single point of success does little to offset the overall trend. The average benchmark score for the AMD part is 49196, which places it in the 90th percentile of all CPUs. The Intel part, despite winning most head-to-head tests, has an average score of 43210 and sits in the 88th percentile. This apparent contradiction is explained by the different benchmark suites recorded for each processor; the AMD chip’s average includes its strong PassMark results, while the Intel chip’s average is pulled down by its Cinebench scores, which are not present in the AMD dataset.

The Verdict

The benchmark data clearly indicates that the Intel Core Ultra 9 386H is the stronger performer in nearly every workload category measured. With a 20.2% lead in single-threaded tests, a 32.6% lead in multithreaded performance, and crushing advantages in physics and floating point math, the Intel part is the superior choice for users who prioritize raw compute throughput.

The AMD Ryzen 7 PRO 5755G, while competitive in integer math, falls behind in all other shared tests. Its 90th percentile ranking versus Intel’s 88th is a function of different benchmark averages, not a sign of equal capability. The data suggests that a user selecting the AMD chip would be accepting a significant performance penalty in exchange for other unspecified attributes, as the recorded numbers do not favor it outside of that single integer math test.

For workloads that depend on floating point, prime number generation, data encryption, or physics simulation, the Intel Core Ultra 9 386H is the clear winner based on recorded deltas. For integer-heavy tasks, the AMD part provides a modest 3.4% improvement, but that is a narrow niche. The verdict from the data is unambiguous: Intel wins the performance comparison, and the AMD chip’s only claim is a small, specialized lead.

Architecture Differences

The two processors are built on fundamentally different architectures from different foundries. AMD uses the Zen 3 architecture, codenamed Cezanne, manufactured on a 7 nm process by TSMC. Intel uses the Panther Lake architecture, which serves as its codename and generation name, fabricated on a 3 nm process at Intel’s own foundry.

The process node difference is significant: 7 nm versus 3 nm. This newer, denser process likely contributes to Intel’s ability to pack 16 cores into a mobile-class chip while maintaining a 25 watt TDP. The AMD part, with 8 cores on 7 nm, has a 65 watt TDP, reflecting its desktop-oriented design and older process technology.

Cache organization differs markedly. The AMD chip has 64 KB of L1 per core, 512 KB of L2 per core, and a 16 MB L3 cache. Intel’s layout is different: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel L2 cache is substantially larger per core, which may explain its strong performance in data compression and encryption workloads, where larger intermediate storage helps.

Transistor count and die size are only recorded for the AMD part: 10,700 million transistors on a 180 mm² die. No such figures exist for Intel in the database. Memory support also diverges: AMD supports DDR4, while Intel supports DDR5 and LPDDR5X. This reflects the generational gap, as the Intel chip is designed for newer memory standards. Memory bandwidth is a major difference, with Intel at 115.2 GB/s versus AMD’s 51.2 GB/s, a direct consequence of the newer memory types.

PCIe connectivity differs as well. The AMD chip offers PCIe Gen 3 with 16 lanes, while Intel offers PCIe Gen 5 with 12 lanes. Intel’s newer standard provides higher per-lane bandwidth, even if the lane count is lower. Integrated graphics also differ: AMD uses Radeon Vega 8, while Intel uses Xe3 Graphics. The Intel part is a mobile processor (BGA 2540 socket), while the AMD part is a desktop processor (AM4 socket). The release dates show Intel launched in early 2026, while AMD launched in late 2024.

Specification Differences

The core and thread counts are a primary differentiator. The AMD Ryzen 7 PRO 5755G has 8 cores and 16 threads. The Intel Core Ultra 9 386H has 16 cores and 16 threads. This means Intel has double the physical cores but does not use simultaneous multithreading; each core provides one thread. AMD uses two threads per core.

Clock speeds also differ. AMD has a base clock of 3.80 GHz and a boost clock of 4.60 GHz. Intel has a lower base of 2.10 GHz but a higher boost of 4.90 GHz. The lower base clock likely helps Intel maintain its 25 watt TDP, while the higher boost clock gives it a single-thread advantage, as seen in the 20.2% single-thread win.

The TDP is starkly different: 65 watts for AMD versus 25 watts for Intel. This makes Intel a far more power-efficient part on paper, which is notable given its superior performance in most tests. The market segments reflect this: AMD is a desktop chip, Intel is a mobile chip. The Intel part’s lower TDP and BGA socket are typical for laptops, while AMD’s AM4 socket is a desktop standard.

Both parts have ECC memory disabled, and neither has an unlocked multiplier. The Intel part’s part number is SA4R5Q9EH, while AMD’s is 100-000001748. The Intel chip’s L3 cache is 18 MB shared, while AMD’s is 16 MB. The Intel L2 cache is 2.5 MB per core, versus AMD’s 512 KB per core. These cache differences, combined with the 3 nm process, are the key specification differences that drive the benchmark outcomes.

Where Each One Wins

The Intel Core Ultra 9 386H wins in the vast majority of workload categories. It is superior in data compression, data encryption, extended instructions, prime number finding, floating point math, multithreaded performance, physics simulation, random string sorting, and single-threaded tasks. This makes it the appropriate choice for any compute-heavy application, including scientific simulation, video encoding, 3D rendering, and data processing. Its 16 physical cores and high boost clock of 4.90 GHz give it a broad performance envelope that dominates the shared benchmark suite.

The AMD Ryzen 7 PRO 5755G wins only in integer math. This is a narrow, specialized victory. For workloads that are purely integer-based, such as certain database operations or legacy software that relies on integer arithmetic, the AMD chip offers a 3.4% improvement over the Intel part. However, this is a small margin and a limited domain. The AMD chip’s higher TDP of 65 watts and older DDR4 memory support suggest it is designed for desktop systems where power efficiency is less critical, but the data does not show a compensating performance benefit outside of integer math.

Given the recorded results, a user running integer-heavy applications might see a minor advantage with the AMD part. For everything else, the Intel Core Ultra 9 386H is the dominant performer. The data does not support any other conclusion: the Intel processor wins 10 of 11 tests, and its losses are confined to a single benchmark with a small delta. The AMD chip’s only strength is a 3.4% integer math lead, which is unlikely to outweigh Intel’s substantial advantages in all other categories.
