Intel Core i9-14901E vs Intel Core Ultra 9 285T Comparison

Intel Core i9-14901E vs Intel Core Ultra 9 285T: a 17-test benchmark comparison shows the Core Ultra 9 285T winning 16 tests, with the Core i9-14901E taking only one. The data indicates a decisive overall performance advantage for the newer Arrow Lake part, driven primarily by its 24 cores versus 8, and its 3 nm process node versus 10 nm. However, the single win for the i9-14901E in the PassMark physics test reveals a specific niche where the older architecture retains an edge.

Where Each One Wins

The Intel Core Ultra 9 285T dominates nearly every workload category recorded in the database. Its wins span all Cinebench rendering tests (both single-core and multi-core), all PassMark computational tests including integer math, floating-point math, data compression, encryption, extended instructions, prime number finding, random string sorting, and the multithreaded benchmark. This broad sweep indicates that the 285T delivers superior performance across productivity, content creation, and general processing tasks.

The Intel Core i9-14901E's sole victory comes in the PassMark physics test, scoring 3041 against the 285T's 2842, a 7% advantage. This test often reflects specific instruction-level efficiencies or cache behavior that favor the older Raptor Lake design in that particular simulation workload. For users running physics-based simulations or similar single-domain workloads, the i9-14901E shows a measurable, though narrow, lead.

The magnitude of the 285T's wins varies by workload. Its smallest edge is in single-threaded performance at 4.9% (4576 versus 4354), while its largest advantage is 45.2% in the find prime numbers test (345 versus 189). The data suggests the 285T is not just faster across the board, but often substantially faster, particularly in tasks that leverage its higher core count or newer instruction set capabilities.

Head-to-Head Benchmarks

The Intel Core Ultra 9 285T's largest victory in the Cinebench suite is consistent across all tests, with a 23.3% delta in its favor for R15 multicore (3384 versus 2595), R15 single-core (477 versus 366), R20 multicore (14100 versus 10816), R20 single-core (1990 versus 1526), R23 multicore (33573 versus 25753), and R23 single-core (4739 versus 3635). This uniformity indicates a systematic advantage in rendering workloads, likely stemming from its 24 cores and 3 nm process node, which allows higher sustained throughput.

The PassMark suite shows a more varied picture. The 285T leads by 45.2% in find prime numbers (345 versus 189), 42.1% in data encryption (32061 versus 18571), 41.2% in floating-point math (137923 versus 81089), and 37.2% in extended instructions (27477 versus 17249). These are substantial margins, pointing to architectural improvements in integer and floating-point execution units, plus better AVX or similar instruction handling. In data compression, the 285T scores 384140 versus 288777, a 24.8% advantage, and in random string sorting it scores 47695 versus 39138, a 17.9% edge.

The only test where the i9-14901E wins is PassMark physics, scoring 3041 against 2842, a 7% margin. This is a notable outlier, as the 285T wins the PassMark multithread test by 24.1% (39931 versus 30298), and the single-thread test by 4.9% (4576 versus 4354). The physics result suggests that the i9-14901E's higher boost clock of 5.60 GHz, combined with its Raptor Lake architecture, provides a specific advantage in that benchmark's particular calculation pattern.

Specification Differences

The two processors differ in nearly every core specification. The Intel Core i9-14901E has 8 cores and 16 threads, while the Intel Core Ultra 9 285T has 24 cores and 24 threads. Base clocks differ significantly: the i9-14901E runs at 2.80 GHz, while the 285T runs at a lower 1.40 GHz base, though the 285T's boost clock of 5.40 GHz is only slightly below the i9-14901E's 5.60 GHz. TDP ratings also diverge, with the i9-14901E rated at 65 watts and the 285T at 35 watts.

Socket compatibility is entirely different: the i9-14901E uses Intel Socket 1700, while the 285T uses Intel Socket 1851. Cache layouts scale with cores: the i9-14901E offers 80 KB L1 per core and 2 MB L2 per core, while the 285T offers 192 KB L1 per core and 3 MB L2 per core; both share 36 MB of L3. Memory support differs, as the i9-14901E supports both DDR4 and DDR5, while the 285T supports only DDR5, though the 285T lists a memory bandwidth of 102.4 GB/s. PCIe lanes also vary, with the i9-14901E providing Gen 5, 16 lanes, and the 285T providing Gen 5, 20 lanes. Integrated graphics are distinct, and the 285T has a launch MSRP of $549.

Architecture Differences

The Intel Core i9-14901E is built on the Raptor Lake architecture (codename Raptor Lake-R) using a 10 nm process node from Intel, with a die size of 257 mm². The Intel Core Ultra 9 285T uses the Arrow Lake architecture (codename Arrow Lake-S) on a 3 nm process node from TSMC, with a die size of 243 mm² and 17,800 million transistors. This process shrink is central to the 285T's performance-per-watt advantage, as it delivers higher core counts at a lower 35 watt TDP.

The core count difference is not just numeric; the 285T has 24 threads matching its 24 cores, indicating no hyper-threading on the efficiency cores, while the i9-14901E has 16 threads from 8 cores, implying hyper-threading on all cores. The cache hierarchy reflects this: the 285T has more than double the L1 cache per core (192 KB versus 80 KB) and 50% more L2 per core (3 MB versus 2 MB), which helps feed its 24 execution threads. The 285T's integrated graphics are also newer, using the Arc Xe-LPG Graphics 64EU versus the older UHD Graphics 770.

Benchmark results indicate that the architectural shift from Raptor Lake to Arrow Lake, combined with the TSMC 3 nm node, yields a significant performance uplift. The 285T's percentile rank of 91 versus the i9-14901E's 86 further contextualizes this, placing the 285T in a higher performance tier among all CPUs in the database.

The Verdict

The Intel Core Ultra 9 285T is the clear performance leader, winning 16 of 17 head-to-head benchmarks. Its average benchmark score of 51310 versus 37911 for the i9-14901E represents a 35.4% overall improvement. For workloads such as video rendering, data compression, encryption, or any multi-threaded application, the 285T's 24 cores and 3 nm architecture provide a substantial advantage, often exceeding 20% and sometimes exceeding 40%. Its lower 35 watt TDP also indicates higher efficiency relative to its performance.

The Intel Core i9-14901E remains relevant only for a narrow use case. Its single win in the PassMark physics test (3041 versus 2842) shows it can outperform the 285T in that specific simulation workload. Additionally, its support for DDR4 memory and its higher 5.60 GHz boost clock may appeal to users with existing DDR4 platforms on Socket 1700, though its 8-core design limits its multi-threaded ceiling. The 285T's single-thread advantage of 4.9% (4576 versus 4354) also means it is not ceding any ground in lightly threaded tasks.

For users prioritizing maximum performance across a wide range of benchmarks, the Intel Core Ultra 9 285T is the superior choice. The data shows no meaningful area, outside of the physics test, where the i9-14901E competes. For users with a specific physics simulation workload or a legacy DDR4 motherboard, the i9-14901E offers a targeted advantage, but the overall benchmark evidence favors the 285T decisively.
