Intel Core 9 270H vs Intel Core Ultra 9 285H Comparison

The Intel Core 9 270H and the Intel Core Ultra 9 285H are two mobile processors that land within 0.1% of each other in average benchmark score, yet they achieve that parity through radically different designs and workload profiles. The data shows a near-total sweep for the Core Ultra 9 285H in head-to-head testing, but the Core 9 270H holds specific, narrow advantages that matter for certain tasks.

Head-to-Head Benchmarks

The Core Ultra 9 285H dominates the benchmark suite, winning 15 of the 17 recorded comparisons. The largest gap appears in PassMark’s find prime numbers test, where the 285H scores 330 versus 112 for the 270H, a 66.1% advantage. This is not a marginal lead; it signals a fundamental difference in how the two chips handle integer-heavy, single-threaded iteration. Floating-point math tells a similar story: the 285H posts 109,190 against 70,640, a 35.3% win. Extended instructions also favor the 285H decisively, with a score of 26,794 versus 20,079, a 25.1% margin.

Multi-core rendering workloads reinforce the 285H’s dominance. In Cinebench R15 multi-core, the 285H scores 3,177.5 versus 2,464, a 22.5% lead. The gap narrows slightly in R20 multi-core (12,201 versus 10,268, or 15.8%) and R23 multi-core (20,781.5 versus 18,000, or 13.4%). PassMark’s multithread test shows a 15.8% advantage for the 285H (34,171 versus 28,764), and physics simulation follows at 21.8% (2,513 versus 1,966). Data encryption is another clear win for the 285H: 26,140 versus 19,369, a 25.9% gap.

The 285H also wins the single-core battles in Cinebench R20 (1,722 versus 1,449, or 15.9%) and R23 (2,129.5 versus 2,040, or 4.2%). PassMark single-thread testing shows a 10.7% lead (4,415 versus 3,944). Even data compression, which is close, goes to the 285H by a slim 0.6% margin (335,859 versus 333,785). Random string sorting favors the 285H by 9.9% (40,931 versus 36,867).

The Core 9 270H wins only two tests, but both are notable. In PassMark integer math, it scores 97,654 versus 85,922 for the 285H, a 13.7% advantage. It also takes Cinebench R15 single-core with a score of 347 versus 313, a 10.9% lead. These are isolated victories, but they indicate the 270H is not obsolete—it simply excels in narrow, specific operations.

Architecture Differences

The two processors come from different Intel design philosophies. The Core 9 270H is built on Raptor Lake, specifically the Raptor Lake-H refresh, and uses a 10 nm process node from Intel’s own foundry. The Core Ultra 9 285H belongs to the Core Ultra Series 2, uses Arrow Lake architecture (Arrow Lake-H), and is fabricated on a 3 nm node by TSMC. This node difference is a major factor in the 285H’s efficiency and performance per clock.

Core and thread counts diverge significantly. The 270H has 14 cores and 20 threads, while the 285H has 16 cores and 16 threads. The 270H relies on Hyper-Threading to reach 20 threads, whereas the 285H does not use simultaneous multithreading. Despite having fewer threads, the 285H wins most multi-core tests, suggesting its extra physical cores and newer architecture more than compensate.

Cache layouts also differ. The 270H features 80 KB of L1 per core and 2 MB of L2 per core, while the 285H offers 192 KB of L1 per core and 3 MB of L2 per core. Both share 24 MB of L3, so the 285H’s advantage lies in faster per-core caches. Memory support is another split: the 270H supports DDR4 and DDR5, while the 285H supports DDR5 and LPDDR5X. The 285H also has a listed memory bandwidth of 102.4 GB/s, a figure absent for the 270H. ECC memory support is present on the 285H but not the 270H.

Clock speeds tell a mixed story. The 270H has a base clock of 2.70 GHz and a boost of 5.80 GHz, while the 285H starts at 2.90 GHz but boosts to 5.40 GHz. The 270H’s higher boost clock helps explain its single-core win in Cinebench R15, but the 285H’s higher base clock and newer architecture give it the edge in most sustained workloads. Both chips run at a 45 W TDP and use Intel BGA sockets, but the 270H uses BGA 1744 while the 285H uses BGA 2049, meaning they are not socket-compatible.

Integrated graphics also differ. The 270H uses Iris Xe Graphics with 96 execution units, while the 285H uses Arc Graphics 140T. Both support PCIe Gen 5 with 8 lanes from the CPU. The 285H was released on 2025-01-12, roughly a month after the 270H’s 2024-12-17 launch. The 270H carries a launch MSRP of $697, while the 285H is listed at $651.

The Verdict

The data is unambiguous: the Intel Core Ultra 9 285H is the faster processor in nearly every measurable way. If the priority is multi-core rendering, data encryption, extended instructions, or floating-point math, the 285H is the correct choice. Its 66.1% lead in prime number finding and 35.3% lead in floating-point math are not minor differences—they represent a generational leap in compute capability. The 285H also holds a 15.8% lead in PassMark multithread and a 13.4% lead in Cinebench R23 multi-core, making it the superior option for heavily threaded workloads.

The Core 9 270H is not without merit. Its 13.7% win in integer math and 10.9% win in Cinebench R15 single-core show that it can outperform the 285H in specific, legacy-oriented tasks. The 270H’s higher boost clock of 5.80 GHz versus 5.40 GHz likely contributes to these wins. However, these two victories do not offset the 285H’s sweep elsewhere. For a user who prioritizes integer-heavy calculations or older single-threaded benchmarks, the 270H is defensible. For everyone else, the 285H is the data-backed pick.

The 285H also offers better memory flexibility with LPDDR5X support and ECC capability, plus a higher listed memory bandwidth. Its 3 nm TSMC node gives it a manufacturing advantage over the 270H’s 10 nm Intel node. The 285H’s 16 cores versus 14 cores, despite fewer threads, proves that physical core count matters more than Hyper-Threading in modern workloads.

Where Each One Wins

The Intel Core Ultra 9 285H is the clear winner for productivity and compute-heavy tasks. It takes data encryption by 25.9%, extended instructions by 25.1%, and floating-point math by 35.3%. These are the workloads that benefit from the 3 nm node and 16 physical cores. For video editing, 3D rendering, scientific simulation, or any task that pushes multi-core utilization, the 285H is the superior choice. Its 15.8% lead in PassMark multithread and 21.8% lead in physics simulation reinforce this.

The 285H also wins in single-core performance in the more modern Cinebench R20 and R23 tests, with leads of 15.9% and 4.2%, respectively. This makes it the better pick for everyday responsiveness and lightly threaded applications. Its PassMark single-thread score of 4,415 versus 3,944 (a 10.7% lead) confirms this advantage.

The Intel Core 9 270H wins where integer math and legacy single-core performance matter. Its 13.7% lead in PassMark integer math suggests it handles integer-heavy code—such as certain database operations or compression algorithms—more efficiently. Its 10.9% win in Cinebench R15 single-core indicates it still holds an edge in older software that does not leverage newer instruction sets. For users running legacy applications or specific integer-bound workloads, the 270H is the data-supported option.

The 285H’s near-total dominance in the head-to-head suite, combined with its ECC support and higher memory bandwidth, makes it the more versatile and future-proof processor. The 270H’s two wins are real but narrow, and they do not translate to broader performance advantages. The data points to the 285H as the default recommendation for most mobile computing scenarios.
