Intel Core i7-14701TE vs Intel Core Ultra 7 366H Comparison

The Verdict

The recorded benchmark data shows a decisive outcome: the Intel Core Ultra 7 366H wins all 17 head-to-head tests against the Intel Core i7-14701TE. The Core Ultra 7 366H delivers an average benchmark score of 41263, placing it in the 87th percentile of all CPUs, while the Core i7-14701TE averages 26013 and sits in the 78th percentile. For anyone choosing between these two, the data points firmly toward the Core Ultra 7 366H for both single-threaded and multi-threaded workloads.

The Core Ultra 7 366H is the pick for mobile users needing maximum compute in a 25 W package. Its 16 cores and 16 threads, combined with a 3 nm process node, deliver consistently higher scores across every measured workload. The Core i7-14701TE, with 8 cores and 16 threads on a 10 nm node, remains a viable desktop option with a 45 W TDP, but it trails by roughly 40% in Cinebench tests and by 21% to 56% in PassMark workloads. The data shows no scenario where the Core i7-14701TE takes the lead.

The Core Ultra 7 366H is also the better choice for portable systems. Its 25 W TDP and mobile socket (Intel BGA 2540) indicate a design for laptops, whereas the Core i7-14701TE uses Intel Socket 1700 and targets desktops. The Core Ultra 7 366H supports LPDDR5X memory, which suits thin-and-light machines, while the Core i7-14701TE supports DDR4 and DDR5. If the platform is a desktop, the Core i7-14701TE fits that socket, but the performance gap in the database makes the Core Ultra 7 366H the stronger processor in raw compute.

Architecture Differences

The two processors come from different generations and design philosophies. The Intel Core i7-14701TE belongs to the Core 14th Gen series, built on the Raptor Lake architecture with the codename Raptor Lake-R. It is part of the Core i7 (Raptor Lake Refresh) generation. The Intel Core Ultra 7 366H belongs to the Core Ultra Series 3, built on the Panther Lake architecture with the codename Panther Lake, and is part of the Ultra 7 (Panther Lake-H) generation.

The process nodes differ sharply. The Core i7-14701TE uses a 10 nm process from Intel with a die size of 257 mm². The Core Ultra 7 366H uses a 3 nm process from Intel, and its die size is not recorded. The smaller process node on the Core Ultra 7 366H contributes to its lower 25 W TDP versus the 45 W TDP of the Core i7-14701TE, despite the Core Ultra having double the cores.

Core and cache layouts diverge. The Core i7-14701TE has 8 cores and 16 threads, with 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Core Ultra 7 366H has 16 cores and 16 threads, with 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Core Ultra has larger per-core caches but less total L3 cache. Neither chip has a 3D V-Cache option, and the transistor counts are not listed for either.

Memory support differs. The Core i7-14701TE supports DDR4 and DDR5 memory with a dual-channel bus. The Core Ultra 7 366H supports DDR5 and LPDDR5X memory with a dual-channel bus, and it has a listed memory bandwidth of 115.2 GB/s, which the Core i7-14701TE lacks in the database.

Where Each One Wins

The Core Ultra 7 366H wins everywhere in the recorded data. There are no benchmark wins for the Core i7-14701TE, so the use-case split is one-sided. The Core Ultra 7 366H is the stronger choice for any workload that appears in the database: rendering, encryption, math operations, sorting, physics, and general multithreaded compute.

The largest wins for the Core Ultra 7 366H come in prime number finding (56.1% ahead), data encryption (54.7%), floating point math (51.5%), and extended instructions (46.6%). These workloads indicate strong integer and floating-point throughput, likely from the 16-core layout and the 3 nm process. The Core Ultra 7 366H also leads in Cinebench multicore and single-core by 40.2%, covering both threaded rendering and single-threaded tasks.

The Core i7-14701TE does not win any benchmark, but its specification advantages are worth noting. It has a higher boost clock (5.20 GHz versus 4.80 GHz), more L3 cache (33 MB versus 18 MB), ECC memory support, and 16 PCIe Gen 5 lanes versus 12. It also supports DDR4, which could matter on older platforms. The data shows these features do not translate into compute wins in the recorded tests.

For desktop builders using Socket 1700, the Core i7-14701TE is the only one of the two that fits that platform. For mobile systems using BGA 2540, the Core Ultra 7 366H is the only option. If the choice is purely on benchmark performance, the Core Ultra 7 366H delivers higher scores across every measured test, with an average benchmark score 58.6% higher than the Core i7-14701TE. The Core Ultra 7 366H also does this at a lower 25 W TDP, making it the more efficient part in the database. The data supports the Core Ultra 7 366H as the superior processor for all recorded workloads.
