Intel Core i5-14401E vs Intel Core Ultra 9 285T Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core Ultra 9 285T across every Cinebench test in the comparison set, with six wins out of six head-to-head matchups. The Intel Core i5-14401E does not take a single benchmark in this group, and the margin is consistent to an unusual degree.

In Cinebench R15, the Ultra 9 285T scores 3384 in multicore against 1830 for the i5-14401E, a delta of -45.9 percent from the perspective of the trailing chip. The single-core R15 test follows the same pattern: 477 for the Ultra 9 285T versus 258 for the i5-14401E, again a -45.9 percent gap. That uniformity across single-core and multicore is notable, as it suggests the advantage is not tied to core count alone, but also to per-thread performance gains.

Moving to Cinebench R20, the Ultra 9 285T records 14100 in multicore, while the i5-14401E manages 7627. The single-core R20 result is 1990 versus 1076. Both deltas sit at -45.9 percent, matching the R15 pattern exactly. In Cinebench R23, the multicore score for the Ultra 9 285T is 33573, nearly double the 18161 posted by the i5-14401E. The single-core R23 result is 4739 against 2564, a similar relative margin.

The percentile data reinforces the divide. The Ultra 9 285T sits at the 91st percentile among all CPUs in the database, while the i5-14401E rests at the 60th percentile. The average benchmark score for the Ultra 9 285T is 51310, compared to 5253 for the i5-14401E, a difference of roughly tenfold when including the Passmark suite that only the Ultra 9 285T has recorded entries for. The nearest rivals for the Ultra 9 285T include the Intel Core i9-14900T with an average score of 51015 and a delta of 0.6 percent, the Intel Core i9-13900F at 51730 with a delta of -0.8 percent, the Intel Core i7-13850HX at 50761 with a delta of 1.1 percent, and the AMD Ryzen 9 5900XT at 50718 with a delta of 1.2 percent. For the i5-14401E, the nearest rivals are the Intel Xeon E5-2699A v4 at 5259 with a delta of -0.1 percent, the Intel Core i7-11700B at 5241 with a delta of 0.2 percent, the Intel Core i9-10850K at 5240 with a delta of 0.2 percent, and the Intel Core i5-13400T at 5210 with a delta of 0.8 percent.

The Passmark results, available only for the Ultra 9 285T, show strengths in data compression with a score of 384140, data encryption at 32061, extended instructions at 27477, floating point math at 137923, integer math at 132433, multithread at 39931, physics at 2842, random string sorting at 47695, and single thread at 4576. The i5-14401E has no recorded Passmark entries in the database, so direct comparison in those workloads is not possible from the available data.

Architecture Differences

The two processors come from different generations and manufacturing nodes. The Intel Core i5-14401E belongs to the Core 14th Gen series, uses the Raptor Lake architecture with the Raptor Lake-R codename, and is built on a 10 nm process at Intel's own foundry. The Intel Core Ultra 9 285T belongs to the Core Ultra Series 2, uses the Arrow Lake architecture with the Arrow Lake-S codename, and is built on a 3 nm process at TSMC. The transistor count for the Ultra 9 285T is listed as 17,800 million, while the i5-14401E has no transistor count recorded. Die size differs as well: the i5-14401E measures 215 mm², and the Ultra 9 285T measures 243 mm².

Core and thread counts differ substantially. The i5-14401E has 6 cores and 12 threads, while the Ultra 9 285T has 24 cores and 24 threads. The thread count matching the core count on the Ultra 9 285T indicates a design without hyperthreading on that part. Clock speeds also diverge: the i5-14401E has a base clock of 2.50 GHz and a boost clock of 4.70 GHz, while the Ultra 9 285T has a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The lower base clock on the Ultra 9 285T is offset by a higher boost clock, and the thermal design power tells a striking story: the i5-14401E is rated at 65 watts, while the Ultra 9 285T is rated at only 35 watts.

Cache hierarchies are built on different scales. The i5-14401E offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The Ultra 9 285T offers 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. Each level of cache is larger on the Ultra 9 285T, both per core and in total.

Memory support separates the two as well. The i5-14401E supports both DDR4 and DDR5 in a dual-channel configuration, while the Ultra 9 285T supports DDR5 only, also dual-channel. The Ultra 9 285T has a recorded memory bandwidth of 102.4 GB/s; no memory bandwidth figure is recorded for the i5-14401E. Both support ECC memory.

PCI Express connectivity differs. The i5-14401E provides Gen 5 with 16 lanes from the CPU, while the Ultra 9 285T provides Gen 5 with 20 lanes from the CPU. Integrated graphics differ: the i5-14401E uses UHD Graphics 730, while the Ultra 9 285T uses Arc Xe-LPG Graphics 64EU.

Sockets are not interchangeable. The i5-14401E uses Intel Socket 1700, while the Ultra 9 285T uses Intel Socket 1851. Neither processor has an unlocked multiplier. Release dates differ by roughly half a year: the i5-14401E was released on 2024-06-30, and the Ultra 9 285T was released on 2025-01-06. Both are listed as Active in production status. The launch MSRP of the Ultra 9 285T is $549, while no launch MSRP is recorded for the i5-14401E.

The Verdict

The benchmark data indicates a decisive performance advantage for the Intel Core Ultra 9 285T in every Cinebench test recorded. The consistent -45.9 percent delta across all six tests means the i5-14401E trails by nearly half in both single-core and multicore workloads. The Ultra 9 285T reaches the 91st percentile among all CPUs in the database, whereas the i5-14401E reaches the 60th percentile.

The architecture gap explains much of the result. The Ultra 9 285T uses a 3 nm process from TSMC, has 24 cores, 36 MB of shared L3 cache, and a 5.40 GHz boost clock, all within a 35 watt TDP. The i5-14401E uses a 10 nm process from Intel, has 6 cores, 20 MB of shared L3 cache, and a 4.70 GHz boost clock, within a 65 watt TDP. The Ultra 9 285T delivers higher performance while carrying a lower thermal design power, which points to a substantially more efficient design.

The i5-14401E does hold some advantages in the recorded specifications. It supports DDR4 memory in addition to DDR5, which may matter for systems with existing DDR4 memory modules. Its socket, Intel Socket 1700, is from an earlier platform generation. Its launch date is earlier, and its lower core count may be sufficient for workloads that do not scale past six cores, though the single-core benchmarks still favor the Ultra 9 285T by the same -45.9 percent margin.

The data does not show any workload category where the i5-14401E wins outright. The nearest rivals for the i5-14401E, such as the Intel Core i7-11700B and the Intel Core i9-10850K, sit very close to its average score, with deltas of 0.2 percent, which places it in a competitive but mid-range performance tier. The Ultra 9 285T, by contrast, competes with the Intel Core i9-14900T and the AMD Ryzen 9 5900XT, with deltas of 0.6 percent and 1.2 percent respectively, placing it in a much higher tier.

Where Each One Wins

The Intel Core Ultra 9 285T wins every benchmark category where both processors have recorded scores. In Cinebench R15, R20, and R23, both multicore and single-core tests favor the Ultra 9 285T by a -45.9 percent margin for the i5-14401E. The Ultra 9 285T additionally has Passmark results across nine workloads, all showing strong absolute scores, though no comparable Passmark data exists for the i5-14401E in the database.

The i5-14401E does not win any recorded benchmark. Its advantages are limited to specification-level differences. It supports DDR4 and DDR5 memory, while the Ultra 9 285T supports DDR5 only. It uses the Intel Socket 1700 platform, which may be relevant for users with existing motherboards on that socket, though the database does not include motherboard compatibility scores. Its 65 watt TDP is higher than the 35 watt TDP of the Ultra 9 285T, which in this case is not a benefit but rather an indicator of lower efficiency, since the Ultra 9 285T delivers higher performance at lower power.

The percentile placement tells the same story. The Ultra 9 285T at the 91st percentile is in the top tier of the database, while the i5-14401E at the 60th percentile is in the middle of the distribution. The nearest rival deltas for each processor confirm the positioning: the Ultra 9 285T trades within 1.2 percent of processors like the Intel Core i9-13900F and the AMD Ryzen 9 5900XT, while the i5-14401E trades within 0.8 percent of parts like the Intel Core i5-13400T and the Intel Core i9-10850K.
