Architecture Differences

The two processors come from different architectural families and target different market segments. The Intel Core i7-14701TE is a desktop part based on Raptor Lake, specifically the Raptor Lake-R refresh, and belongs to the Core 14th Gen series. It uses the Intel Socket 1700. The Intel Core Ultra X9 378H is a mobile processor with the Panther Lake codename, part of the Core Ultra Series 3, and uses Intel BGA 2540.

The manufacturing process differs substantially. The desktop chip is fabricated on a 10 nm node with a die size of 257 mm². The mobile chip uses a 3 nm node; its die size is not recorded in the database. The process advantage for the Ultra X9 378H aligns with its lower power envelope.

Core organization also differs. The i7-14701TE has 8 cores and 16 threads, meaning each core handles two threads. The Ultra X9 378H has 16 cores and 16 threads, so each core handles one thread. Cache hierarchies are different as well. The i7-14701TE provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra X9 378H provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The desktop chip therefore holds a larger total L3 pool, while the mobile chip has larger per-core L1 and L2 allocations.

Memory support diverges. The i7-14701TE supports DDR4 and DDR5 memory in a dual-channel configuration. The Ultra X9 378H supports only LPDDR5X, also dual-channel, with a recorded memory bandwidth of 153.6 GB/s. The i7-14701TE supports ECC memory; the Ultra X9 378H does not.

Integrated graphics differ. The desktop chip uses UHD Graphics 770, while the mobile chip uses Arc B390. PCIe connectivity also differs: the i7-14701TE provides Gen 5 with 16 lanes (CPU only), whereas the Ultra X9 378H provides Gen 5 with 4 lanes (CPU only).

The release dates are separated by nearly two years. The i7-14701TE launched on 2024-06-30, and the Ultra X9 378H launched on 2026-04-03. Both are active production parts, both are multiplier-locked, and neither has a recorded launch MSRP.

Where Each One Wins

The Intel Core Ultra X9 378H wins every benchmark recorded in the database, so the use-case split is determined by the magnitude of its advantages and the platform characteristics, not by individual benchmark victories.

The largest margins for the Ultra X9 378H appear in encryption and prime-number workloads. It leads by 60.8% in PassMark data encryption and by 59.9% in PassMark find prime numbers. These are substantial gaps, indicating the mobile chip handles cryptographic and integer-heavy algorithmic tasks with far greater efficiency. Extended instructions also favor the Ultra X9 378H by 54.2%, and floating-point math by 56.1%.

The smallest advantage is in PassMark integer math, where the Ultra X9 378H leads by 29.0%. That still represents a decisive win, but it shows the desktop chip is relatively closer in pure integer throughput. The i7-14701TE's higher boost clock of 5.20 GHz likely narrows the gap in this workload, though it does not close it.

The i7-14701TE retains relevance through its desktop platform attributes. It supports DDR4 and DDR5 memory, which offers memory flexibility, and it provides 16 PCIe Gen 5 lanes for expansion. It also supports ECC memory, which is relevant for reliability-sensitive desktop workloads. The Ultra X9 378H, by contrast, is limited to LPDDR5X memory and 4 PCIe Gen 5 lanes, which constrains expansion options.

The power envelope is another differentiator. The i7-14701TE has a TDP of 45 watts, while the Ultra X9 378H has a TDP of 25 watts. The mobile chip delivers higher performance across all recorded tests while drawing less power, which makes it the stronger choice for thermally constrained systems. The desktop chip's higher TDP and socketed design suit conventional desktop builds.

Head-to-Head Benchmarks

The Intel Core Ultra X9 378H dominates the head-to-head results, winning all 17 recorded comparisons. The Cinebench suite shows a consistent pattern across both multi-core and single-core tests.

In Cinebench R15 multi-core, the Ultra X9 378H scores 3281 against 1716 for the i7-14701TE, a 47.7% difference. The single-core result is nearly identical in percentage terms: 462 versus 242, also 47.6%. Cinebench R20 follows the same pattern, with the Ultra X9 378H scoring 13672 multi-core and 1929 single-core, against 7154 and 1010 for the desktop chip, both 47.7% and 47.6% gaps respectively. Cinebench R23 multi-core shows 32553 versus 17035, a 47.7% difference, and single-core shows 4595 versus 2405, also 47.7%.

The PassMark suite reveals a wider spread of margins. The largest advantage for the Ultra X9 378H is in data encryption, where it scores 29840 against 11699, a 60.8% lead. Find prime numbers shows a 59.9% gap, with scores of 357 and 143. Floating-point math favors the Ultra X9 378H by 56.1%, with 114500 against 50219. Extended instructions show a 54.2% lead, with 31315 versus 14354.

Random string sorting favors the Ultra X9 378H by 49.0%, with 44648 against 22760. Multi-thread performance shows a 47.7% gap, with 38298 versus 20042. Physics tests show a 45.4% difference, with 3404 against 1860. Data compression shows a 43.0% lead, with 386591 versus 220520.

Single-thread performance in PassMark shows a 40.8% gap, with 4453 against 2637. The smallest margin is in integer math, where the Ultra X9 378H scores 92603 against 65792, a 29.0% lead.

The average benchmark scores reflect this overall dominance. The Ultra X9 378H averages 47468, while the i7-14701TE averages 26013. The nearest rival comparisons reinforce the positioning. The i7-14701TE sits within 0.7% of several AMD mobile and desktop parts, including the AMD Ryzen AI 5 340, AMD Ryzen 5 8640HS, AMD Ryzen 5 PRO 5655GE, and AMD Ryzen 5 8540U. The Ultra X9 378H sits within 0.6% of much stronger parts, including the AMD Ryzen 9 PRO 5945, Intel Core i7-13700KF, Intel Core Ultra 7 265T, and Intel Core i9-12900F.

The data indicates the Ultra X9 378H delivers roughly double the multi-core performance of the i7-14701TE across Cinebench tests, with single-core gains of approximately 90% or more. Its advantages in encryption and prime-number workloads are even larger. The i7-14701TE's higher boost clock and larger L3 cache do not translate into any recorded benchmark win, though the 29.0% integer-math gap shows the desktop chip is comparatively more competitive in that specific workload.
