Intel Core i7-14650HX vs Intel Core Ultra 5 336H Comparison

The Intel Core i7-14650HX and Intel Core Ultra 5 336H represent two distinct approaches to mobile processing, with the former built on a mature high-core-count design and the latter on a newer, more efficient node. The benchmark data reveals a clear split: the i7-14650HX dominates in heavily threaded workloads, while the Ultra 5 336H counters with superior single-thread and specific instruction-level performance. This analysis walks through the recorded measurements to determine where each processor stands.

Head-to-Head Benchmarks

The most decisive victory for the Intel Core i7-14650HX appears in the PassMark integer math test, where it scores 116661 against 62070 for the Ultra 5 336H, a margin of 88%. This is the largest delta in the entire comparison and indicates a substantial advantage in arithmetic-heavy integer operations. The i7-14650HX also wins the Cinebench R15 multicore test with 3470.5 versus 2418, a 43.5% lead, and the PassMark data compression test with 398418 versus 280340, a 42.1% advantage. These results point to a processor that scales effectively across many concurrent threads.

The multi-core dominance continues in Cinebench R20, where the i7-14650HX scores 11946 against 10076 for the Ultra 5 336H, a 18.6% lead. The PassMark multithread test shows a similar pattern, with the i7-14650HX at 33495 and the Ultra 5 336H at 28545, a 17.3% difference. Random string sorting also favors the i7-14650HX, 43035 to 34402, a 25.1% margin. Data encryption is closer, with the i7-14650HX ahead at 22917 versus 21291, a 7.6% edge.

The overall win count is close, with the i7-14650HX taking 9 of the 17 recorded tests and the Ultra 5 336H taking 8. The margin of victory, however, differs sharply: the i7-14650HX wins by an average of 88% in its best case, while the Ultra 5 336H counters with a 41.9% single-core lead. The average benchmark score confirms the split, with the i7-14650HX at 41576 and the Ultra 5 336H at 34485.

Architecture Differences

The two processors use fundamentally different silicon. The Intel Core i7-14650HX is built on the Raptor Lake architecture with a 10 nm process node, while the Intel Core Ultra 5 336H uses the Panther Lake architecture on a 3 nm node. Both are manufactured by Intel, but the process difference is significant: the 3 nm node allows the Ultra 5 336H to achieve higher clocks at a lower thermal envelope. The i7-14650HX has a base clock of 2.20 GHz and a boost clock of 5.20 GHz, while the Ultra 5 336H runs at 1.90 GHz base and 4.60 GHz boost. Despite the lower clocks, the Ultra 5 336H posts higher single-core scores, which suggests the newer architecture delivers more instructions per clock.

Core counts are identical at 16, but thread counts differ. The i7-14650HX supports 24 threads, indicating hyperthreading, while the Ultra 5 336H has 16 threads, matching its core count. This explains the i7-14650HX's advantage in multi-threaded tests like Cinebench R15, where additional threads provide a 43.5% lead. The socket also differs: the i7-14650HX uses Intel BGA 1964, while the Ultra 5 336H uses Intel BGA 2540. The i7-14650HX has an unlocked multiplier, while the Ultra 5 336H is locked.

Cache configurations diverge substantially. The i7-14650HX has 80 KB of L1 cache per core, 2 MB of L2 per core, and 30 MB of shared L3. The Ultra 5 336H has 192 KB of L1 per core, 2.5 MB of L2 per core, but only 18 MB of shared L3. The larger L1 and L2 caches on the Ultra 5 336H may contribute to its single-thread performance, while the larger L3 on the i7-14650HX helps with multi-threaded data sharing. The die size for the i7-14650HX is 257 mm², while the Ultra 5 336H does not have a recorded die size.

Memory support differs as well. The i7-14650HX supports DDR4 and DDR5 in a dual-channel configuration, and it has ECC memory support. The Ultra 5 336H supports DDR5 and LPDDR5X, also dual-channel, but does not support ECC. The Ultra 5 336H has a recorded memory bandwidth of 115.2 GB/s, while the i7-14650HX has no bandwidth figure in the data. PCIe lanes also differ: the i7-14650HX provides Gen 5 with 16 lanes, while the Ultra 5 336H provides Gen 5 with 12 lanes. Integrated graphics are different as well, with the i7-14650HX using UHD Graphics 710 and the Ultra 5 336H using Intel Xe3 Graphics.

Where Each One Wins

The Intel Core i7-14650HX is the clear choice for workloads that scale with thread count. Its 24 threads versus 16 give it a structural advantage in multi-threaded rendering, data compression, and integer math. The Cinebench R15 multi-core score of 3470.5 versus 2418 shows a 43.5% lead, and the PassMark integer math score of 116661 versus 62070 shows an 88% lead. For tasks like video encoding, 3D rendering, or database operations that use many cores, the i7-14650HX delivers measurably higher throughput. The PassMark multithread score of 33495 versus 28545 confirms this, as does the random string sorting result of 43035 versus 34402.

The Intel Core Ultra 5 336H wins in single-thread and latency-sensitive tasks. Its Cinebench R23 single-core score of 3387 versus 1969 is a 41.9% advantage, which is the largest single-thread gap in the data. The Cinebench R15 single-core score of 341 versus 285.5 reinforces this, and the PassMark single-thread score of 4013 versus 3841 adds another win. The find prime numbers test, where the Ultra 5 336H scores 299 versus 152, suggests superior performance in algorithms with heavy branching or sequential dependencies. The physics test also favors the Ultra 5 336H, 2682 versus 2202, indicating better performance in simulation workloads that rely on single-thread physics calculations.

The Cinebench R23 multi-core result is an outlier that deserves attention. The Ultra 5 336H wins that test with 23991 against 20454, a 14.7% margin, even though the i7-14650HX wins the R15 and R20 multi-core tests. This suggests the R23 workload is less sensitive to thread count and more sensitive to per-core efficiency, where the newer Panther Lake architecture excels. The Ultra 5 336H also wins the extended instructions test, 24542 versus 24150, though the margin is slim at 1.6%. For workloads that use modern instruction sets, the Ultra 5 336H holds a slight edge.

The Verdict

The data supports a clear division. The Intel Core i7-14650HX is the stronger processor for multi-threaded throughput, winning 9 of 17 tests with decisive margins in integer math, data compression, and Cinebench R15 multi-core. Its 24 threads and larger 30 MB L3 cache provide a structural advantage that shows up in every thread-scaled benchmark. The average benchmark score of 41576 versus 34485, a difference of about 20.6%, reflects this overall lead, and the i7-14650HX sits at the 88th percentile against all CPUs, while the Ultra 5 336H sits at the 84th percentile.

The Intel Core Ultra 5 336H is the better choice for single-thread performance and efficiency. Its Cinebench R23 single-core score is 41.9% higher, and it wins the physics and find prime numbers tests. The lower TDP of 25 watts versus 55 watts indicates it operates in a more efficient envelope, though the data does not include power measurements. The 3 nm process node and larger per-core caches (192 KB L1, 2.5 MB L2) likely drive these wins, as does the higher boost clock efficiency. For applications that rely on a few fast cores, the Ultra 5 336H is the superior part.

The nearest rivals in the database confirm the positioning. The i7-14650HX sits within 0.5% of the AMD Ryzen 9 5900X and is 0.1% behind the Intel Core Ultra 7 265H. The Ultra 5 336H is 0.2% behind the Intel Core i7-13700HX and 0.4% ahead of the Intel Core i5-13450HX. These comparisons place the i7-14650HX in desktop-class territory for multi-core work, while the Ultra 5 336H aligns with previous-generation high-end mobile chips. Users who prioritize multi-threaded rendering or compilation should select the i7-14650HX, while users who prioritize responsive single-threaded applications or power-sensitive workloads should select the Ultra 5 336H.
