Intel Core i9-14900T vs Intel Core Ultra 5 336H Comparison

The Intel Core i9-14900T and the Intel Core Ultra 5 336H represent two distinct philosophies in processor design. The i9-14900T is a 35 W desktop part from the Raptor Lake Refresh generation, built on a 10 nm process, while the Ultra 5 336H is a 25 W mobile processor from the Panther Lake family, manufactured on a 3 nm node. The recorded data shows a clear split in their capabilities, with the desktop chip dominating most raw throughput tests while the mobile part counters in specific single-threaded and specialized workloads. This analysis examines the benchmark results to determine where each processor delivers its strongest performance.

Where Each One Wins

The Intel Core i9-14900T wins 14 of the 17 head-to-head comparisons in the database. Its most decisive victories come in workloads that scale with core count and memory bandwidth. The integer math test shows the largest margin, with the i9-14900T scoring 138149 against the Ultra 5 336H's 62070, a 122.6% advantage. Data compression also favors the desktop part heavily, at 436066 versus 280340, a 55.5% lead. These results align with the i9-14900T's configuration of 24 cores and 32 threads, compared to 16 cores and 16 threads for the Ultra 5 336H. The larger 36 MB shared L3 cache on the i9-14900T, versus 18 MB on the mobile chip, likely contributes to its strength in data-heavy tasks.

The Intel Core Ultra 5 336H wins only 3 benchmarks, but they reveal distinct strengths. The find prime numbers test shows the mobile processor at 299 versus 164 for the i9-14900T, a 45.2% advantage. This is a notable reversal, suggesting the Panther Lake architecture's per-core efficiency excels in certain mathematical workloads. The physics test also goes to the Ultra 5 336H, scoring 2682 against 2245, a 16.3% lead. Extended instructions is the third win, with the Ultra 5 336H at 24542 versus 23660, a 3.6% margin. These wins indicate that despite fewer cores and lower overall throughput, the newer 3 nm process and Panther Lake microarchitecture deliver superior performance in specific instruction paths.

Single-thread performance is nearly identical. The passmark single_thread test shows the i9-14900T at 4016 and the Ultra 5 336H at 4013, a 0.1% difference. Across the Cinebench suite, however, the i9-14900T maintains a consistent 28.4% lead in both single-core and multi-core tests. This suggests the desktop chip's higher 5.50 GHz boost clock, versus 4.60 GHz for the mobile part, provides a sustained advantage in rendering workloads, even where the newer architecture closes the gap in other single-thread tests.

The Verdict

The data indicates that the Intel Core i9-14900T is the stronger processor for multi-threaded and integer-heavy workloads. Its 90th percentile ranking among all CPUs, compared to the Ultra 5 336H's 84th percentile, reflects its higher average benchmark score of 51015 versus 34485. The i9-14900T's nearest rivals include the Intel Core Ultra 9 285T at 51310, a 0.6% difference, and the AMD Ryzen 9 5900XT at 50718, a 0.6% difference. This places it in a competitive tier with high-end desktop parts. The Ultra 5 336H, by contrast, sits near the Intel Core i7-13700HX at 34554, a 0.2% difference, indicating it competes with previous-generation mobile HX chips.

For users prioritizing rendering, data compression, or any workload that uses all available threads, the i9-14900T is the clear choice based on the benchmark deltas. Its 28.4% lead across every Cinebench test and 122.6% lead in integer math are decisive. The Ultra 5 336H, however, offers a different value proposition in the database: it wins the prime number and physics tests, and its extended instructions score exceeds the i9-14900T. This makes it suitable for workloads that depend on those specific operations, such as certain scientific simulations or encryption-related tasks, where its 3 nm process efficiency may also matter in mobile environments.

The i9-14900T's 35 W TDP and desktop socket, Intel Socket 1700, contrast with the Ultra 5 336H's 25 W TDP and mobile BGA 2540 socket. The database does not include thermal or power efficiency measurements, but the TDP figures suggest the mobile part is designed for constrained environments. The i9-14900T, with a launch MSRP of $549, targets desktop builds where power is less of a constraint. The Ultra 5 336H has no recorded launch MSRP. The verdict from the data is straightforward: the i9-14900T for maximum throughput, the Ultra 5 336H for specific algorithmic strengths and lower power draw.

Head-to-Head Benchmarks

The Cinebench suite provides the most consistent comparison. Across R15, R20, and R23, the i9-14900T wins both single-core and multi-core tests by exactly 28.4% each time. In R15 multi-core, the scores are 3104 versus 2418. In R20 multi-core, they are 12937 versus 10076. In R23 multi-core, they are 30803 versus 23991. The single-core results follow the same pattern: 438 versus 341 in R15, 1826 versus 1422 in R20, and 4348 versus 3387 in R23. This uniformity suggests a consistent architectural advantage for the i9-14900T in Cinebench's rendering workload, likely tied to its higher boost clock and larger thread count.

The PassMark suite reveals more varied outcomes. The largest delta is in integer math, where the i9-14900T scores 138149 against 62070, a 122.6% advantage. This is the most lopsided result in the entire comparison. Floating point math also favors the desktop part, 92699 versus 82415, a 12.5% lead. Data encryption shows a 27.1% advantage for the i9-14900T, at 27062 versus 21291. Random string sorting goes to the i9-14900T by 43.8%, with scores of 49484 and 34402. The multithread test shows a 27% lead, 36239 versus 28545.

The Ultra 5 336H's wins are concentrated in three tests. The find prime numbers result is its strongest, 299 versus 164, a 45.2% margin. This is the only test where the mobile chip leads by more than 20%. The physics test shows a 16.3% advantage, 2682 versus 2245. Extended instructions is a narrow win, 24542 versus 23660, a 3.6% margin. These results indicate that the Panther Lake architecture handles certain instruction sequences more efficiently, even though it trails in broader workloads. The passmark single_thread test is essentially a tie, 4016 versus 4013, reinforcing that single-thread performance is not a differentiator between these two processors.
