Intel Core 9 270H vs Intel Core Ultra 9 386H Comparison

Intel Core 9 270H and Intel Core Ultra 9 386H represent two distinct approaches to mobile computing, separated by a generational gap in architecture and design philosophy. The benchmark data shows a clear overall winner, but the specific workloads where the older chip retains an advantage are equally revealing.

Head-to-Head Benchmarks

The Intel Core Ultra 9 386H dominates the head-to-head comparison, winning 15 of the 17 recorded benchmarks. Its average benchmark score of 43210 places it in the 88th percentile of all CPUs, while the Core 9 270H averages 38335, good for the 86th percentile. The 386H’s nearest rivals include the AMD Ryzen AI Max PRO 385, which scores 43326, a difference of only 0.3 percent, and the AMD Ryzen AI 9 465 at 43431, which leads by 0.5 percent. The 270H, by contrast, sits within 0.3 percent of the AMD Ryzen 7 250 and just 0.2 percent behind the Intel Core i5-13600HX.

The largest single margin comes in the PassMark find prime numbers test, where the 386H scores 341 against the 270H’s 112, a 67.2 percent advantage. This is a specialized workload, but the scale of the gap points to a fundamental difference in how the two processors handle integer-heavy iterative tasks. The 386H also shows a 35.1 percent lead in PassMark physics (3028 vs 1966) and a 34.9 percent lead in floating point math (108527 vs 70640). Data encryption favors the 386H by 28.7 percent (27150 vs 19369), and extended instructions by 31.1 percent (29138 vs 20079).

Cinebench multicore results consistently favor the 386H. In Cinebench R23 multicore, the 386H scores 20547 against 18000, a 12.4 percent lead. The R20 multicore gap is larger at 19.9 percent (12820 vs 10268), and the R15 multicore gap reaches 23.5 percent (3223 vs 2464). PassMark multithread shows an 18.7 percent advantage for the 386H (35399 vs 28764). Data compression favors the 386H by 5.3 percent (352365 vs 333785), and random string sorting by 12.5 percent (42135 vs 36867).

Single-thread results are much closer. The 386H wins Cinebench R23 single-core by only 1.5 percent (2071.5 vs 2040) and PassMark single-thread by 6.5 percent (4218 vs 3944). The R20 single-core test shows a 19.9 percent lead for the 386H (1809 vs 1449), but the R15 single-core test is the exception: the 270H wins by 14.3 percent (347 vs 303.5). The other win for the 270H comes in PassMark integer math, where it scores 97654 against 87284, an 11.9 percent advantage. These two wins indicate that the 270H retains a measurable edge in certain scalar and integer operations despite losing the overall performance war.

The Verdict

The data indicates that the Intel Core Ultra 9 386H is the stronger processor for the vast majority of workloads. Multi-threaded rendering, encryption, physics simulation, and general productivity all favor the 386H by margins ranging from 5.3 percent to over 67 percent. Its 88th percentile standing, combined with a higher average benchmark score of 43210, puts it in company with desktop-class parts like the Intel Core i9-12900, which sits only 0.7 percent behind, and the Core i9-12900KF at 0.9 percent behind.

The Core 9 270H is not without merit. Its 14.3 percent win in Cinebench R15 single-core and 11.9 percent win in PassMark integer math show that its higher boost clock of 5.80 GHz can still deliver wins in latency-sensitive single-threaded tasks. However, those two wins are isolated. The 386H counters with wins in every other single-thread test, including a 6.5 percent lead in PassMark single-thread and a 1.5 percent lead in Cinebench R23 single-core.

For buyers choosing between these two, the 386H is the data-backed pick for users who prioritize rendering, encryption, physics, or any multi-threaded workload. The 270H is the choice only for a narrow set of integer and legacy single-thread scenarios, and even there the margins are inconsistent across test versions. The 386H also carries a lower TDP of 25 watts against the 270H’s 45 watts, which suggests that the performance advantage does not come at the cost of higher power draw on paper.

Specification Differences

The two processors differ across nearly every major specification category. The Intel Core 9 270H uses 14 cores and 20 threads, while the Intel Core Ultra 9 386H uses 16 cores and 16 threads. The 270H has a higher base clock of 2.70 GHz versus 2.10 GHz, and a higher boost clock of 5.80 GHz versus 4.90 GHz. The 270H carries a 45 watt TDP, while the 386H is rated at 25 watts.

Sockets differ completely: the 270H uses Intel BGA 1744, while the 386H uses Intel BGA 2540. Memory support splits as well, with the 270H supporting DDR4 and DDR5, while the 386H supports DDR5 and LPDDR5X. The 386H has a recorded memory bandwidth of 115.2 GB/s, while no bandwidth figure is recorded for the 270H. PCIe lanes differ, with the 270H offering Gen 5 with 8 CPU lanes and the 386H offering Gen 5 with 12 CPU lanes. Integrated graphics differ, with the 270H using Iris Xe Graphics 96EU and the 386H using Intel Xe3 Graphics.

The 270H has a launch MSRP of $697, while no launch MSRP is recorded for the 386H. Neither processor has an unlocked multiplier. The 270H has part number SRQ6V, and the 386H has part number SA4R5Q9EH.

Architecture Differences

Architecturally, these are two very different designs. The Intel Core 9 270H is based on Raptor Lake, specifically the Raptor Lake-H codename, and belongs to the Core 9 (Raptor Lake Refresh) generation. It is manufactured on a 10 nm process at Intel. The Intel Core Ultra 9 386H is based on Panther Lake, with the Panther Lake-H codename, belongs to the Ultra 9 (Panther Lake-H) generation, and uses a 3 nm process node, also at Intel.

Cache layouts diverge significantly. The 270H has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The 386H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The 386H therefore has substantially more L1 and L2 cache per core, while the 270H has more total L3 cache.

The thread count difference is notable: the 270H has 20 threads from 14 cores, implying hyperthreading, while the 386H has 16 threads from 16 cores, meaning no hyperthreading. The 386H compensates with more physical cores, two additional ones, and a smaller process node. The 270H’s higher boost clock of 5.80 GHz gives it a raw frequency advantage, but the 386H’s architectural efficiency and lower TDP of 25 watts suggest a fundamentally different design target. The 386H also supports a wider PCIe configuration with 12 CPU lanes versus 8. Both are mobile processors, both are active in production, and neither supports ECC memory, but the underlying silicon generations could hardly be more different.
