The Verdict

The recorded data points to a decisive performance tier split. The Intel Core Ultra 7 366H wins all 17 head-to-head benchmark comparisons. Its average benchmark score of 41263 is more than double the 17648 average of the Core i3-14100T. The percentile placement reinforces this: the Ultra 7 sits at the 87th percentile of all CPUs, while the i3-14100T sits at the 71st percentile.

The Core i3-14100T remains a sensible choice for desktop builds where the Intel Socket 1700 platform, ECC memory support, and a 35 W TDP matter more than raw throughput. It pairs with DDR4 or DDR5, includes UHD Graphics 730, and uses a 10 nm process node. Its nearest rivals, the Core i3-13100F and Core i7-1255U, show average scores of 17653 and 17656 respectively, placing the i3-14100T within a fraction of a percent of those parts.

The Core Ultra 7 366H, by contrast, targets mobile systems with its Intel BGA 2540 socket, 25 W TDP, and 3 nm process node. Its nearest rivals include the Core Ultra 7 356H at 41215 and the AMD Ryzen 9 5900X at 41376, meaning the 366H trades blows with desktop-class silicon from the previous generation. Buyers who need heavy multi-threaded workloads, such as rendering or data compression, should favor the Ultra 7 366H based on the benchmark record.

Head-to-Head Benchmarks

The Core Ultra 7 366H dominates the benchmark suite, and the margin varies by workload type. The largest gap appears in PassMark find prime numbers, where the Ultra 7 scores 326 against 56 for the i3-14100T, a 82.8 percent deficit for the desktop part. Floating-point math shows a 69.7 percent gap, with 103615 versus 31379. Data encryption shows a 69.5 percent gap, with 25845 versus 7881.

The smallest difference is in PassMark single-thread, where the Ultra 7 leads by 13.5 percent, scoring 4043 versus 3498. That narrow margin suggests the i3-14100T's 4.40 GHz boost clock keeps single-threaded performance competitive, though the Ultra 7's 4.80 GHz boost still wins. The Cinebench single-core tests tell a different story: R23 single-core shows 4020 versus 1639, a 59.2 percent gap, and R15 single-core shows 405 versus 165, a 59.3 percent gap.

Multi-threaded workloads consistently show the Ultra 7 at roughly 59 percent ahead. Cinebench R23 multi-core, R20 multi-core, and R15 multi-core all show deltas of 59.2 percent. PassMark multithread shows a 59.1 percent gap, with 33429 versus 13662. The consistency across rendering workloads indicates the 16-core, 16-thread configuration of the Ultra 7 delivers a stable advantage over the 4-core, 8-thread i3-14100T.

PassMark integer math shows 83695 versus 40292, a 51.9 percent gap. Data compression shows 327455 versus 152636, a 53.4 percent gap. Extended instructions show 26901 versus 10414, a 61.3 percent gap. Random string sorting shows 39814 versus 15579, a 60.9 percent gap. Physics shows 2880 versus 973, a 66.2 percent gap. Every workload category records a win for the Ultra 7, and the deltas stay within a narrow band of roughly 52 to 83 percent.

Specification Differences

The two processors differ in nearly every core specification. The Core i3-14100T has 4 cores and 8 threads, while the Core Ultra 7 366H has 16 cores and 16 threads. The i3-14100T has a base clock of 2.70 GHz and a boost clock of 4.40 GHz. The Ultra 7 366H has a lower base clock of 2.00 GHz but a higher boost clock of 4.80 GHz.

Thermal design power differs by 10 W: the i3-14100T is rated at 35 W, while the Ultra 7 366H is rated at 25 W. The socket types are incompatible. The i3-14100T uses Intel Socket 1700, a desktop platform, while the Ultra 7 366H uses Intel BGA 2540, a mobile platform. The market segments reflect this: the i3-14100T is listed as Desktop, and the Ultra 7 366H is listed as Mobile.

Memory support diverges. The i3-14100T supports DDR4 and DDR5, whereas the Ultra 7 366H supports DDR5 and LPDDR5X. The Ultra 7 366H lists a memory bandwidth of 115.2 GB/s; the i3-14100T does not list a memory bandwidth figure. ECC memory is supported on the i3-14100T but not on the Ultra 7 366H.

PCIe connectivity differs in lane count. The i3-14100T provides Gen 5 with 16 lanes (CPU only), while the Ultra 7 366H provides Gen 5 with 12 lanes (CPU only). Integrated graphics also differ: the i3-14100T uses UHD Graphics 730, and the Ultra 7 366H uses Intel Xe3 Graphics.

The launch MSRP for the i3-14100T is $134. The Ultra 7 366H has no launch MSRP recorded. The i3-14100T has a die size of 163 mm², while the Ultra 7 366H has no die size recorded. Both processors have locked multipliers.

Architecture Differences

The architecture gap is substantial. The Core i3-14100T belongs to the Core 14th Gen series and uses Raptor Lake architecture, specifically the Raptor Lake-R codename. It is built on a 10 nm process node at Intel's foundry. The Core Ultra 7 366H belongs to the Core Ultra Series 3 and uses Panther Lake architecture with the Panther Lake-H codename, built on a 3 nm process node, also at Intel.

Cache hierarchy differs across all levels. The i3-14100T has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. The Ultra 7 366H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The larger per-core caches on the Ultra 7 align with its higher core count and newer process node.

Release timing separates the two generations. The i3-14100T has a release date of 2024-01-07, while the Ultra 7 366H has a release date of 2026-01-04, roughly two years later. The production status for both is Active.

The generation labels reflect the product positioning: the i3-14100T is listed as Core i3 (Raptor Lake Refresh), while the Ultra 7 366H is listed as Ultra 7 (Panther Lake-H). The part numbers differ as well: SRMX0 for the i3-14100T and SA4R9Q9EL for the Ultra 7 366H.

The nearest rival data confirms the Ultra 7 366H competes in a higher performance class. Its closest competitors include the Core Ultra 7 356H at 41215, the AMD Ryzen AI 5 PRO 440 at 41208, and the AMD Ryzen 9 5900X at 41376, with deltas of 0.1, 0.1, and -0.3 percent respectively. The i3-14100T's nearest rivals, the Core i3-13100F and Core i7-1255U, sit within 0.3 percent of its average score, indicating the 14th Gen desktop part is essentially tied with its immediate predecessors and comparable mobile parts.
