The Verdict

The benchmark data points to a clear overall winner: the Intel Core Ultra 7 366H dominates the head-to-head comparison, taking 16 of 17 recorded tests. Its average benchmark score of 41263 is roughly 26% higher than the i5-14600T's 32707, and its 87th percentile ranking versus the i5's 83rd percentile confirms a higher standing in the overall CPU distribution.

For users prioritizing raw multi-threaded performance in a mobile form factor, the Ultra 7 366H is the choice. It delivers substantially higher Cinebench R23 multicore scores (28477 versus 22447) and PassMark multithread results (33429 versus 26409). The chip's lower 25 W TDP also indicates it achieves this performance in a more power-efficient envelope than the i5-14600T's 35 W.

The Intel Core i5-14600T retains relevance for specific workloads. Its 13.6% win in PassMark integer math shows strength in integer-heavy tasks. The desktop chip also offers ECC memory support, a feature absent from the Ultra 7 366H, and supports both DDR4 and DDR5 memory, while the Ultra 7 366H only supports DDR5 and LPDDR5X.

The Ultra 7 366H's nearest rivals in the database include the Intel Core Ultra 7 356H with a delta of 0.1%, the AMD Ryzen AI 5 PRO 440 at 0.1%, and the AMD Ryzen 9 5900X at -0.3%. The i5-14600T's closest competitors are the Intel Core Ultra 7 155H at 0% delta, the AMD Ryzen 5 7400F at -0.1%, and the AMD Ryzen AI 7 PRO 360 at 0.1%. These figures place both chips in similar performance tiers among their respective peers.

Head-to-Head Benchmarks

Single-thread PassMark scores are closer but still favor the Ultra 7 366H. The mobile chip records 4043, the desktop i5-14600T scores 3744, a 7.4% difference. The same delta appears in the PassMark singlethread entry, which repeats the identical values.

The Intel Core i5-14600T's sole victory comes in PassMark integer math. It scores 95112 versus the Ultra 7 366H's 83695, a 13.6% margin. This is the only test in the entire head-to-head dataset where the desktop chip outperforms the mobile part. The result suggests integer arithmetic is a particular strength of the Raptor Lake architecture, despite the overall performance deficit elsewhere.

Specification Differences

The two processors differ in nearly every fundamental specification. The Intel Core i5-14600T has 14 cores and 20 threads, while the Intel Core Ultra 7 366H has 16 cores and 16 threads. Base clocks differ: 1.80 GHz for the i5-14600T versus 2.00 GHz for the Ultra 7 366H. Boost clocks also diverge, with the desktop chip reaching 5.10 GHz against the mobile chip's 4.80 GHz.

Power envelopes are distinct. The i5-14600T carries a 35 W TDP, the Ultra 7 366H a 25 W TDP. Sockets are incompatible: Intel Socket 1700 for the desktop part, Intel BGA 2540 for the mobile part.

Memory support varies. The i5-14600T supports DDR4 and DDR5, while the Ultra 7 366H supports DDR5 and LPDDR5X. Both use dual-channel memory buses. The Ultra 7 366H lists a memory bandwidth of 115.2 GB/s, while the i5-14600T has no recorded bandwidth figure. ECC memory is supported on the i5-14600T but not on the Ultra 7 366H.

PCIe lanes differ: the i5-14600T provides Gen 5 with 16 CPU lanes, the Ultra 7 366H provides Gen 5 with 12 CPU lanes. Integrated graphics are different as well, with the UHD Graphics 770 on the i5-14600T and Intel Xe3 Graphics on the Ultra 7 366H.

Release dates are far apart. The i5-14600T launched on 2024-01-07, while the Ultra 7 366H launched on 2026-01-04. The i5-14600T has a recorded launch MSRP of $255. The Ultra 7 366H does not have a launch MSRP in the database.

Cache configurations differ significantly. The i5-14600T uses 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Ultra 7 366H uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3.

Architecture Differences

The Intel Core i5-14600T is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, part of the Core 14th Gen series. The Intel Core Ultra 7 366H uses Panther Lake architecture, specifically Panther Lake-H, part of the Core Ultra Series 3. These are two distinct generations with different design philosophies.

Process nodes are a major divergence. The i5-14600T is fabricated on a 10 nm process, while the Ultra 7 366H uses a 3 nm process. Both are manufactured by Intel, but the smaller node gives the Ultra 7 366H a substantial density and efficiency advantage. The i5-14600T has a recorded die size of 257 mm², while the Ultra 7 366H has no die size recorded.

Core counts and threading models reflect different design choices. The i5-14600T uses 14 cores with hyperthreading to reach 20 threads, a hybrid approach common in desktop parts. The Ultra 7 366H uses 16 cores with no hyperthreading, giving 16 threads. The Ultra 7 366H trades thread count for more physical cores, which may benefit certain parallel workloads.

Cache architecture shows the newer process's advantage. The Ultra 7 366H allocates 192 KB of L1 per core versus 80 KB on the i5-14600T, and 2.5 MB of L2 per core versus 2 MB. However, the i5-14600T has more shared L3 cache: 24 MB versus 18 MB. This means the desktop chip offers a larger last-level cache for the entire package, while the mobile chip provides more per-core cache.

Market segments differ completely. The i5-14600T is a desktop processor, while the Ultra 7 366H is a mobile processor. The Ultra 7 366H's lower TDP, BGA socket, and LPDDR5X support all align with laptop designs, while the i5-14600T's socket and DDR4 compatibility target traditional desktop builds.

The integrated graphics units reflect their respective generations. The i5-14600T uses UHD Graphics 770, a Raptor Lake era solution. The Ultra 7 366H uses Intel Xe3 Graphics, a newer architecture that pairs with the Panther Lake platform. The database does not include graphics benchmarks, so relative GPU performance cannot be assessed from this data.

Both processors have locked multipliers, so neither offers unlocked overclocking. Both are listed as Active in production status. The i5-14600T's part number is SRN46, while the Ultra 7 366H's part number is SA4R9Q9EL. The release cadence shows the Ultra 7 366H arriving roughly two years after the i5-14600T, consistent with Intel's generational progression from Raptor Lake to Panther Lake.
