Intel Core i9-14900F vs Intel Core Ultra 7 356H Comparison

Head-to-Head Benchmarks

The benchmark data for the Intel Core i9-14900F and the Intel Core Ultra 7 356H shows a clear overall leader, with the desktop processor taking 16 of the 17 recorded head-to-head tests. The i9-14900F wins by margins ranging from a razor-thin 0.1% to a dominant 173.7%, while the Ultra 7 356H secures a single win in one specific workload.

The most striking difference appears in the Cinebench R23 single-core test. The i9-14900F scores 5583 against 2040 for the Ultra 7 356H, a delta of 173.7%. This is the largest gap in any benchmark recorded, and it highlights how far apart the two processors are in raw single-thread performance. The Cinebench R23 multi-core result also shows a massive separation: 39551 for the i9-14900F versus 18395 for the Ultra 7 356H, a 115% advantage. In Cinebench R20, the i9-14900F leads by 36.7% in both single-core (2344 versus 1715) and multi-core (16611 versus 12153) tests. The Cinebench R15 results follow the same pattern: the i9-14900F leads by 30.5% in multi-core (3986 versus 3055) and by 85.5% in single-core (562 versus 303).

PassMark results reinforce the multi-threaded advantage. The i9-14900F scores 177066 in integer math versus 83111 for the Ultra 7 356H, a 113% lead. Data compression shows a 67.8% advantage (564207 versus 336177), and random string sorting favors the i9-14900F by 55.5% (63728 versus 40990). The multi-thread test itself shows 46532 for the i9-14900F versus 33978 for the Ultra 7 356H, a 36.9% gap. Data encryption favors the i9-14900F by 31.5% (34644 versus 26345), and floating point math shows a 15.9% lead (119550 versus 103128).

Single-thread PassMark results are closer but still favor the i9-14900F: 4506 versus 4072, a 10.7% gap. Extended instructions show a narrower margin of 11.4% (31084 versus 27898). The physics test is essentially a tie: 2899 for the i9-14900F versus 2895 for the Ultra 7 356H, a 0.1% difference that falls within negligible territory.

The sole win for the Ultra 7 356H comes in the find prime numbers test, where it scores 327 against 209 for the i9-14900F. This represents a 36.1% advantage for the mobile chip, a notable outlier in an otherwise one-sided comparison. The prime number test measures a specific pattern of integer operations, and the Ultra 7 356H's result suggests its architecture handles this workload more efficiently relative to its overall performance profile.

Where Each One Wins

The Intel Core i9-14900F wins across most productivity and compute-oriented workloads. Its 24 cores and 32 threads provide a substantial parallel processing advantage, visible in the Cinebench multi-core tests and the PassMark multi-thread result. The data compression and encryption scores indicate strong performance for file archiving, database workloads, and security-related tasks. The integer math advantage of 113% positions the i9-14900F clearly ahead for compilation, scientific computing, and any workload that relies heavily on integer arithmetic.

The single-core wins for the i9-14900F, particularly the 173.7% lead in Cinebench R23 single-core, suggest it also handles lightly threaded applications such as legacy software, scripting, and certain office tasks with far greater speed. The extended instructions result, while narrower at 11.4%, still favors the desktop part for vectorized code and modern instruction set usage.

The Intel Core Ultra 7 356H wins exclusively in the find prime numbers test. This benchmark typically stresses a tight loop of integer division and modular arithmetic, and the 36.1% margin indicates the Panther Lake architecture has an efficient path for this specific operation. Outside of that single test, the Ultra 7 356H does not outperform the i9-14900F in any recorded measurement. Its closest relative performance comes in the physics test, where the 0.1% gap is statistically insignificant.

For workloads that fit within the Ultra 7 356H's strengths, the mobile chip offers a different balance: its 3 nm process node and lower thermal envelope (25 W TDP versus 65 W for the i9-14900F) suggest it is designed for sustained operation in thin and light laptops rather than peak throughput. The data does not include power efficiency metrics, but the TDP figures alone indicate the Ultra 7 356H operates at a much lower power budget while still delivering roughly two-thirds of the i9-14900F's multi-threaded performance in several tests.

The Verdict

The recorded data points to the Intel Core i9-14900F as the higher-performing processor in nearly every measured category. Its average benchmark score of 60008 places it in the 92nd percentile of all CPUs, while the Ultra 7 356H averages 41215 and sits in the 87th percentile. The i9-14900F also compares favorably to its nearest rivals: it trails the AMD Ryzen 9 7945HX by only 0.2% and the AMD Ryzen 7 8745HX by 0.2%, while leading the AMD Ryzen 9 7945HX3D by 0.6% and the Intel Xeon Gold 6338T by 0.9%. The Ultra 7 356H's nearest rivals are much closer in score: it matches the AMD Ryzen AI 5 PRO 440 exactly (0% delta), trails the Intel Core Ultra 7 366H by 0.1%, trails the AMD Ryzen 9 5900X by 0.4%, and leads the Intel Core Ultra X7 358H by 0.6%.

For users who need maximum multi-threaded throughput, the i9-14900F is the clear pick. Its 115% lead in Cinebench R23 multi-core and 113% lead in PassMark integer math make it suitable for rendering, video encoding, software compilation, and other parallel workloads. The single-core advantage also benefits responsive everyday use and lightly threaded applications. The i9-14900F is a desktop part with a 65 W TDP, Intel Socket 1700 compatibility, and a launch MSRP of $524.

The Ultra 7 356H serves a different purpose. As a mobile processor with a 25 W TDP and Intel BGA 2540 socket, it is designed for laptops where power efficiency and thermal management take priority over raw performance. Its single win in the prime numbers test shows that it has specific architectural strengths, but the overall benchmark picture indicates it is not a competitor for the i9-14900F in performance-oriented desktop builds. The Ultra 7 356H's data suggests it delivers capable performance for a mobile chip, with its average score placing it in the 87th percentile overall, but it does not approach the i9-14900F's output in the recorded tests.

Architecture Differences

The two processors come from different Intel architectures and target different market segments. The Intel Core i9-14900F uses the Raptor Lake architecture, specifically the Raptor Lake-R codename, and belongs to the Core 14th Gen series. It is built on a 10 nm process node at Intel's foundry with a die size of 257 mm². The Intel Core Ultra 7 356H uses the Panther Lake architecture with the Panther Lake codename, belongs to the Core Ultra Series 3, and is built on a 3 nm process node, also at Intel's foundry. Its die size is not recorded in the database.

The cache hierarchies differ substantially. The i9-14900F has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Ultra 7 356H 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 L1 and L2 caches on the Ultra 7 356H suggest a different core design optimized for the newer Panther Lake architecture, while the i9-14900F compensates with a much larger total L3 cache.

Integrated graphics also separate the two. The i9-14900F has no integrated graphics (listed as N/A), meaning it requires a discrete GPU for any display output.
