Intel Core Ultra 7 270K Plus vs Intel Core Ultra 9 285T Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core Ultra 7 270K Plus, which wins 15 of the 17 recorded head-to-head comparisons. The Intel Core Ultra 9 285T takes only 2 wins, both in specific single-core Cinebench tests, but the magnitude of the Ultra 7's multi-core dominance is the defining story of this matchup.

The largest performance gap appears in PassMark extended instructions, where the Ultra 7 270K Plus scores 63,506 against the Ultra 9 285T's 27,477, a 131.1% advantage. This indicates a substantial difference in workloads that leverage advanced instruction sets, likely reflecting the Ultra 7's higher sustained clock behavior. Similarly, data compression shows a 109.4% lead for the Ultra 7, with scores of 804,322 versus 384,140. Random string sorting follows at 103.3% ahead, confirming that the Ultra 7 handles memory-heavy and algorithmic workloads far more effectively.

Multi-core rendering benchmarks reinforce the pattern. In Cinebench R15 multi-core, the Ultra 7 scores 6,656 against 3,384, a 96.7% delta. Cinebench R20 multi-core shows a 73.5% lead (24,461 versus 14,100), and Cinebench R23 multi-core narrows this to 31.8% (44,253 versus 33,573). The R23 result suggests that as the workload extends over time, the Ultra 9 285T's power-efficient design can close some ground, but it still trails by nearly a third.

PassMark multithread performance gives the Ultra 7 a 71.7% advantage (68,574 versus 39,931). Data encryption shows an 84.3% lead for the Ultra 7 (59,097 versus 32,061). Prime number finding, a classic integer throughput test, favors the Ultra 7 by 78.3% (615 versus 345). Floating point math sees a 66.4% gap (229,491 versus 137,923), and integer math a 32.9% gap (175,986 versus 132,433). Physics calculations put the Ultra 7 ahead by 43% (4,064 versus 2,842).

The two wins for the Ultra 9 285T are notable for their inconsistency. In Cinebench R15 single-core, the Ultra 9 scores 477 against 354, a 25.8% advantage for the Ultra 9. In Cinebench R23 single-core, the Ultra 9 leads 4,739 versus 2,439, a 48.5% margin. However, in PassMark single-thread, the situation reverses completely: the Ultra 7 scores 5,068 versus 4,576, a 10.8% lead. The divergence between Cinebench single-core tests and PassMark single-thread suggests the two processors have very different boost behavior depending on the instruction mix and duration of the workload.

In the aggregate, the Ultra 7 270K Plus posts an average benchmark score of 93,785, placing it in the 96th percentile of all CPUs. The Ultra 9 285T averages 51,310, in the 91st percentile. The nearest rivals in the database for the Ultra 7 are server-class parts: the Intel Xeon 6520P at 93,786 (0% delta), the AMD EPYC 4564P at 95,183 (-1.5%), the AMD EPYC 9175F at 95,615 (-1.9%), and the AMD EPYC 4565P at 95,764 (-2.1%). For the Ultra 9 285T, the nearest rivals are desktop and mobile parts: the Intel Core i9-14900T at 51,015 (0.6% ahead), the Intel Core i9-13900F at 51,730 (0.8% behind), the Intel Core i7-13850HX at 50,761 (1.1% ahead), and the AMD Ryzen 9 5900XT at 50,718 (1.2% ahead). The data places the Ultra 7 in a performance tier roughly 83% above the Ultra 9's average score, a gap far larger than the difference in their percentile rankings might suggest.

The Verdict

The recorded data supports a clear choice for workloads that depend on sustained multi-core throughput. The Intel Core Ultra 7 270K Plus leads in every multi-core test in the database, with margins ranging from 31.8% in Cinebench R23 multi-core to 109.4% in data compression. For rendering, data processing, encryption, and scientific computing, the Ultra 7 is the stronger part by a wide margin. Its average benchmark score of 93,785 versus 51,310, combined with its 96th percentile ranking, places it in a different performance class.

The Intel Core Ultra 9 285T is the pick only for a narrow scenario: single-core Cinebench workloads. Its wins in Cinebench R15 single-core (477 versus 354) and Cinebench R23 single-core (4,739 versus 2,439) are substantial in percentage terms, but they do not extend to PassMark single-thread, where the Ultra 7 leads by 10.8%. The Ultra 9's lower base clock of 1.40 GHz versus 3.70 GHz and its 35W TDP versus 125W TDP indicate it is designed for efficiency, and the data shows it delivers far lower performance outside of specific burst workloads.

Users who need maximum throughput across a broad mix of applications should select the Ultra 7 270K Plus. Users whose primary metric is single-core Cinebench performance, and who can accept a 35W power envelope, may find the Ultra 9 285T suitable. The data otherwise shows no scenario where the Ultra 9 outperforms the Ultra 7 outside those two tests.

Specification Differences

The two processors share the same core and thread count: 24 cores and 24 threads each. Both use the Intel Socket 1851, support DDR5 memory in dual-channel configuration, and include integrated Arc Xe-LPG Graphics with 64 execution units. Both support ECC memory and use the same PCIe configuration: Gen 5 with 20 lanes from the CPU.

The differences begin with clock speeds. The Ultra 7 270K Plus has a base clock of 3.70 GHz and a boost clock of 5.50 GHz. The Ultra 9 285T has a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The TDP differs dramatically: the Ultra 7 is rated at 125W, while the Ultra 9 is rated at 35W.

Memory bandwidth also differs. The Ultra 7 supports 115.2 GB/s, while the Ultra 9 supports 102.4 GB/s. The multiplier is unlocked on the Ultra 7, allowing overclocking, while the Ultra 9 has a locked multiplier. The Ultra 7 carries the part number SA4V6 and has a launch MSRP of $299. The Ultra 9 carries the part number SRQD3 and has a launch MSRP of $549. Release dates differ as well: the Ultra 7 was released on 2026-03-10, while the Ultra 9 was released on 2025-01-06.

Architecture Differences

Both processors are built on the same 3 nm process node from TSMC, with the same transistor count of 17,800 million and the same die size of 243 mm². Cache structures are identical: 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3.

The codenames differ slightly. The Ultra 7 270K Plus uses the codename Arrow Lake Refresh, while the Ultra 9 285T uses Arrow Lake-S. The Ultra 7's generation is listed as "Ultra 7 (Arrow Lake)" and the Ultra 9's as "Ultra 9 (Arrow Lake)." The Ultra 9 has an explicit architecture entry of "Arrow Lake," while the Ultra 7's architecture field is null, though its codename indicates a refresh of the same family.

Both parts integrate the same graphics solution, Arc Xe-LPG Graphics with 64 execution units, and both offer Gen 5 PCIe with 20 CPU lanes. The fundamental architectural difference is not in the core layout or cache hierarchy, which are identical, but in the operating envelope: the Ultra 7 runs at much higher clocks and power, while the Ultra 9 is constrained to 35W. The benchmark data indicates this power difference, not the architecture, drives the performance gap. The Ultra 7's unlocked multiplier further distinguishes it, allowing users to push clocks beyond the 5.50 GHz boost, while the Ultra 9's locked multiplier caps its ceiling at 5.40 GHz.
