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

Head-to-Head Benchmarks

The benchmark data shows a decisive sweep in favor of the Intel Core Ultra 9 285. Across all 17 recorded tests, the Core Ultra 9 285 posts a higher score than the Intel Core 9 270H, with no single test going the other way. The largest margins appear in multi-threaded workloads, where the Core Ultra 9 285's additional cores and different architecture produce substantial leads.

In Cinebench R23 multi-core, the Core Ultra 9 285 scores 48,945 against 18,000 for the Core 9 270H, a delta of negative 63.2 percent from the perspective of the Core 9 270H. That is the widest gap in the Cinebench suite. The single-core R23 test shows an even larger relative deficit for the Core 9 270H: 2,040 versus 6,909, a 70.5 percent difference. The Cinebench R15 multi-core test shows 4,933 for the Core Ultra 9 285 versus 2,464, and the single-core R15 test shows 696 versus 347, both at negative 50.1 percent. Cinebench R20 multi-core is 20,556 versus 10,268 (negative 50 percent), and R20 single-core is 2,901 versus 1,449 (negative 50.1 percent).

PassMark results follow the same pattern. The largest delta appears in prime number finding, where the Core Ultra 9 285 scores 459 versus 112, a negative 75.6 percent difference. Floating point math shows 194,988 versus 70,640, a negative 63.8 percent margin. Data encryption shows 46,949 versus 19,369, a negative 58.7 percent difference. Extended instructions show 45,357 versus 20,079, negative 55.7 percent. Random string sorting shows 73,651 versus 36,867, negative 49.9 percent. Multithread performance shows 56,602 versus 28,764, negative 49.2 percent. Physics shows 3,598 versus 1,966, negative 45.4 percent. Data compression shows 602,121 versus 333,785, negative 44.6 percent. Integer math shows 164,869 versus 97,654, negative 40.8 percent.

The smallest relative gap in the entire dataset is in PassMark single-thread performance, where the Core Ultra 9 285 scores 4,881 versus 3,944 for the Core 9 270H, a negative 19.2 percent difference. This indicates that while the Core Ultra 9 285 leads in every metric, the single-thread advantage is noticeably smaller than the multi-thread advantage. The average benchmark score for the Core Ultra 9 285 is 75,488, while the Core 9 270H averages 38,335. The Core Ultra 9 285 sits in the 95th percentile of all CPUs, while the Core 9 270H sits in the 86th percentile.

The nearest rival data confirms the positioning. The Core 9 270H's closest competitor is the Intel Core Ultra 9 285H, which has an average score of 38,312 and a delta of 0.1 percent, meaning the Core 9 270H is essentially tied with that part. The Core Ultra 9 285's nearest rival is the AMD EPYC 8224P at 75,582, a negative 0.1 percent delta, again a near tie. These comparisons place the two chips in different performance tiers entirely.

Where Each One Wins

The Intel Core Ultra 9 285 wins every recorded benchmark, so the practical question is not which chip wins but where the margins are meaningful. The data shows a clear split between single-thread and multi-thread workloads. In single-thread tests, the Core Ultra 9 285 leads by 19.2 percent in PassMark single-thread and by 70.5 percent in Cinebench R23 single-core. The Cinebench single-core deltas are much larger than the PassMark single-thread delta, which suggests the architectural differences manifest differently across test suites.

For multi-threaded rendering, the Core Ultra 9 285 delivers roughly 2.7 times the Cinebench R23 multi-core score of the Core 9 270H. That is the largest multi-thread margin in the Cinebench set. The PassMark multithread test shows a smaller but still substantial 49.2 percent lead. For integer-heavy tasks, the Core Ultra 9 285 leads by 40.8 percent, the smallest multi-thread delta in the PassMark suite. For floating-point heavy tasks, the lead expands to 63.8 percent.

The Core 9 270H does not win any test outright. Its closest performance relative to the Core Ultra 9 285 appears in PassMark single-thread and integer math, where the deltas are 19.2 percent and 40.8 percent respectively. The data indicates that the Core 9 270H is competitive in lightly threaded integer workloads but falls far behind in heavily threaded and floating-point scenarios. The Core 9 270H has a higher boost clock at 5.80 GHz versus 5.60 GHz for the Core Ultra 9 285, and a higher base clock at 2.70 GHz versus 2.50 GHz, yet it still trails in every benchmark, pointing to core count and architecture as the dominant factors.

The part numbers are SRQ6V for the Core 9 270H and SRQD4 for the Core Ultra 9 285.

Architecture Differences

The architectural split is substantial. The Intel Core 9 270H uses Raptor Lake architecture with the Raptor Lake-H codename and belongs to the Core 9 (Raptor Lake Refresh) generation. The Intel Core Ultra 9 285 uses Arrow Lake architecture with the Arrow Lake-S codename and belongs to the Ultra 9 (Arrow Lake) generation. The process nodes differ: the Core 9 270H is built on a 10 nm process by Intel, while the Core Ultra 9 285 is built on a 3 nm process by TSMC.

The Core Ultra 9 285 has recorded transistor and die size data: 17,800 million transistors on a 243 mm² die. The Core 9 270H has no recorded transistor count or die size. Cache hierarchies differ across all levels. The Core 9 270H has 80 KB of L1 per core and 2 MB of L2 per core, with 24 MB of shared L3. The Core Ultra 9 285 has 192 KB of L1 per core and 3 MB of L2 per core, with 36 MB of shared L3.

The core count difference is 14 versus 24, and the thread count difference is 20 versus 24. The Core 9 270H supports Hyper-Threading (20 threads from 14 cores), while the Core Ultra 9 285 has 24 threads from 24 cores, indicating no hyper-threading and a different core topology.

The PCIe implementation differs in lane count, with the Core Ultra 9 285 providing 20 Gen 5 lanes versus 8 lanes for the Core 9 270H. The production status for both is active, but the socket, process node, foundry, and die size all point to a generational leap rather than a simple refresh. The Core Ultra 9 285's 3 nm TSMC process and larger cache per core explain a significant portion of its benchmark advantage, particularly in single-thread tests where the clock speed difference is small (5.60 GHz versus 5.80 GHz) yet the scores are much higher.
