Intel Core i5-14600 vs Intel Core Ultra 7 366H Comparison

Head-to-Head Benchmarks

The recorded data presents a clear split between these two processors. The Intel Core i5-14600 wins 12 of the 17 head-to-head comparisons, while the Intel Core Ultra 7 366H takes 5. The margins, however, tell a more nuanced story about their respective strengths.

In the Cinebench suite, the i5-14600 is consistently ahead. The R15 multicore test shows a score of 3070 against 2870, a 7% advantage. R15 singlecore repeats the pattern at 433 versus 405, a 6.9% lead. The R20 multicore result is 12794 against 11960, another 7% gap, and R20 singlecore shows 1806 versus 1688, again 7%. R23 multicore delivers 30464 versus 28477, and R23 singlecore 4300 versus 4020, both holding that same 7% margin. These results indicate a uniform single-threaded and multithreaded advantage in rendering workloads.

The Passmark multithread test confirms the trend, with the i5-14600 scoring 35848 against 33429, a 7.2% win. Passmark single thread shows 4167 versus 4043, a narrower 3.1% edge. The largest victory for the i5-14600 comes in Passmark integer math, where it scores 117078 against 83695, a commanding 39.9% delta. Data compression also favors the desktop chip heavily: 434620 versus 327455, a 32.7% lead. Random string sorting adds another win at 48043 versus 39814, a 20.7% gap.

The Ultra 7 366H, meanwhile, secures its wins in specific computational areas. Passmark find prime numbers shows a dramatic reversal: 326 versus 155, meaning the Ultra 7 scores 52.5% higher. Floating point math goes to the Ultra 7 at 103615 versus 85759, a 17.2% edge. Physics tests favor the mobile chip at 2880 versus 2330, a 19.1% lead. Data encryption is close but still a win for the Ultra 7: 25845 versus 25082, a 3% difference. Extended instructions also go to the Ultra 7 at 26901 versus 25674, a 4.6% margin.

The pattern is unmistakable. The i5-14600 dominates integer-heavy, compression, sorting, and general rendering tasks. The Ultra 7 366H excels at prime number calculation, floating point operations, physics simulation, encryption, and extended instruction workloads. Neither chip is universally superior; their wins align with distinct computational demands.

Where Each One Wins

The benchmark data suggests the i5-14600 is the stronger choice for workloads that rely on high memory bandwidth for integer operations and compression. Data compression at 32.7% ahead, random string sorting at 20.7% ahead, and integer math at 39.9% ahead all point to a processor that handles data movement and arithmetic-heavy tasks with ease. The consistent 7% lead across every Cinebench iteration, both single and multi-core, also makes it the better candidate for rendering and content creation that scales with thread count and clock speed.

The Ultra 7 366H, by contrast, shows its strength in specialized mathematical and physics-based workloads. The 52.5% lead in prime number finding is striking, and it suggests superior handling of specific algorithmic patterns. Floating point math at 17.2% ahead indicates better throughput for scientific or engineering calculations that depend on fractional arithmetic. Physics simulation at 19.1% ahead further supports this interpretation. Encryption at 3% ahead and extended instructions at 4.6% ahead round out a profile that favors non-integer, non-compression tasks.

For users running general productivity, software compilation, or media encoding, the i5-14600 appears better suited based on its multicore Cinebench results and Passmark multithread score. For users whose software relies on floating point density, prime number sieving, or physics solvers, the Ultra 7 366H has the measurable edge. The data does not support a single all-around winner; it supports a workload-dependent choice.

Architecture Differences

The two processors come from different architectural lineages and target different market segments. The i5-14600 is a desktop part built on Raptor Lake, specifically the Raptor Lake-R refresh, using a 10 nm process node from Intel. It fits the Intel Socket 1700 platform. The Ultra 7 366H is a mobile processor based on Panther Lake, built on a 3 nm process node, also from Intel, and uses the Intel BGA 2540 socket.

Core configurations differ notably. The i5-14600 has 14 cores and 20 threads, while the Ultra 7 366H has 16 cores and 16 threads. The desktop chip uses hyperthreading to exceed its core count, while the mobile chip does not. Clock speeds also diverge: the i5-14600 has a base clock of 2.70 GHz and a boost clock of 5.20 GHz; the Ultra 7 366H has a 2.00 GHz base and 4.80 GHz boost. Power envelopes reflect their intended environments, with the i5-14600 rated at 65W and the Ultra 7 366H at 25W.

Cache hierarchies are structured differently. The i5-14600 provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Ultra 7 366H offers 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The larger per-core L1 and L2 on the Ultra 7 may contribute to its floating point and physics wins, while the larger shared L3 on the i5-14600 may help with its compression and integer performance.

Memory support differs as well. The i5-14600 supports DDR4 and DDR5 in dual-channel mode, with no listed memory bandwidth figure. The Ultra 7 366H supports DDR5 and LPDDR5X in dual-channel mode, with a recorded memory bandwidth of 115.2 GB/s. The desktop chip supports ECC memory; the mobile chip does not. PCIe capability also varies: the i5-14600 provides Gen 5 with 16 CPU lanes, while the Ultra 7 366H provides Gen 5 with 12 CPU lanes. Integrated graphics differ, with the i5-14600 using UHD Graphics 770 and the Ultra 7 366H using Intel Xe3 Graphics.

The release dates place the i5-14600 in early 2024 and the Ultra 7 366H in early 2026. The i5-14600 has a listed launch MSRP of $255; no launch MSRP is recorded for the Ultra 7 366H. The i5-14600 die size is 257 mm², while no die size is recorded for the Ultra 7 366H. Neither processor has an unlocked multiplier. The i5-14600 part number is SRN44, and the Ultra 7 366H part number is SA4R9Q9EL.

The Verdict

Benchmark results indicate that the Intel Core i5-14600 is the stronger processor for most measured workloads. It wins 12 of 17 comparisons, including every Cinebench test, all with a 7% or near-7% margin. Its wins in integer math at 39.9%, data compression at 32.7%, and random string sorting at 20.7% are substantial. Its average benchmark score of 44889 places it in the 89th percentile of all CPUs, with its nearest rival, the Intel Core i9-12900KS, only 0.5% ahead, and the AMD Ryzen 5 7500X3D 0.7% behind.

The Intel Core Ultra 7 366H, while losing the overall count, demonstrates clear superiority in specific domains. Its average benchmark score of 41263 places it in the 87th percentile, with the Intel Core Ultra 7 356H just 0.1% ahead and the AMD Ryzen 9 5900X 0.3% ahead. The prime number finding result of 326 versus 155 is the single largest delta in either direction across all tests. Floating point math, physics, encryption, and extended instructions all favor the mobile chip.

The choice depends on the workload. The data supports the i5-14600 for integer-heavy, compression-heavy, and rendering tasks. It supports the Ultra 7 366H for floating point, physics, and specialized instruction workloads. The desktop chip also offers higher boost clocks, more threads, larger shared L3, and ECC support. The mobile chip offers a smaller process node, more cores, larger per-core caches, higher measured memory bandwidth, and a much lower power envelope. These are not interchangeable parts; they serve different platforms and different computational priorities.
