Intel Core i7-14701E vs Intel Core Ultra 5 336H Comparison

The Intel Core i7-14701E and Intel Core Ultra 5 336H represent two distinct approaches to processor design, one rooted in high-clock desktop performance and the other in a power-efficient mobile architecture. The benchmark data shows a clear overall winner in the Core Ultra 5 336H, which claims 13 of the 17 head-to-head comparisons, while the i7-14701E takes 4 wins. This split is not merely about core counts; it reflects fundamental architectural priorities that show up in specific workloads.

Head-to-Head Benchmarks

The most decisive victories for the Core Ultra 5 336H come in the Passmark instruction and math tests. In data encryption, the Ultra 5 336H scores 21291 against 14862 for the i7-14701E, a 30.2% advantage. Extended instructions show a 24.5% lead, with scores of 24542 versus 18528. The floating point math test reinforces this pattern: 82415 for the Ultra 5 336H versus 61873 for the i7-14701E, a 24.9% delta. The largest single gap appears in find prime numbers, where the Ultra 5 336H posts 299 against 176, a 41.1% difference. These results indicate a substantial advantage in parallel computational throughput for the newer architecture.

The Core Ultra 5 336H also sweeps the Cinebench suite, though by narrower margins. In R23 multicore, it scores 23991 versus 22195 for the i7-14701E, a 7.5% lead. The R23 singlecore test shows 3387 against 3133, also a 7.5% delta. This consistency extends across R15 and R20 versions, where every multicore and singlecore test shows the same 7.5% or 7.6% advantage for the Ultra 5 336H. The Passmark multithread test follows suit with 28545 versus 26112, an 8.5% lead, and physics shows 2682 versus 2399, a 10.6% edge. Random string sorting completes the picture with 34402 against 29158, a 15.2% win.

The i7-14701E counters with three notable wins. Its Passmark single thread score of 4305 beats the Ultra 5 336H's 4013 by 7.3%. In integer math, the i7-14701E scores 81325 versus 62070, a commanding 31% lead. Data compression is a narrow win: 282939 versus 280340, just 0.9% ahead. These wins show that the older desktop chip retains strength in specific scalar workloads and integer-heavy processing.

Architecture Differences

The two processors come from different foundry processes and design philosophies. The i7-14701E uses Intel's 10 nm process, while the Ultra 5 336H is built on a 3 nm node. This process gap likely explains much of the efficiency and performance density differences. The die size for the i7-14701E is 257 mm², while no die size is recorded for the Ultra 5 336H, suggesting the newer chip may be significantly smaller.

Core configurations differ sharply. The i7-14701E has 8 cores and 16 threads, while the Ultra 5 336H has 16 cores and 16 threads. This means the Ultra 5 336H has twice the core count but no hyperthreading, while the i7-14701E relies on simultaneous multithreading to reach its thread count. The cache hierarchy reflects the different designs: the i7-14701E offers 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The Ultra 5 336H has 192 KB L1 per core, 2.5 MB L2 per core, but only 18 MB shared L3. The larger per-core L1 and L2 in the Ultra 5 336H likely feed its higher throughput in math-heavy tests, while the smaller L3 suggests a different memory hierarchy strategy.

Clock speeds tell another story. The i7-14701E runs at a 2.60 GHz base clock and boosts to 5.40 GHz, while the Ultra 5 336H starts at 1.90 GHz and boosts to 4.60 GHz. Despite the lower clocks, the Ultra 5 336H wins most benchmarks, pointing to superior IPC from the newer Panther Lake architecture. The power envelope is drastically different: the i7-14701E has a 65 W TDP, while the Ultra 5 336H is rated at 25 W. This 40 W gap makes the Ultra 5 336H's benchmark dominance more impressive relative to its power draw.

Memory support also differs. The i7-14701E supports both DDR4 and DDR5, while the Ultra 5 336H supports DDR5 and LPDDR5X. The Ultra 5 336H has a recorded memory bandwidth of 115.2 GB/s, while no bandwidth figure exists for the i7-14701E. PCIe lanes differ as well: the i7-14701E offers Gen 5 with 16 lanes, while the Ultra 5 336H provides Gen 5 with 12 lanes. The i7-14701E supports ECC memory, a feature absent from the Ultra 5 336H. Integrated graphics are different generations: UHD Graphics 770 for the i7-14701E, Intel Xe3 Graphics for the Ultra 5 336H.

Where Each One Wins

The data creates a clear use-case split. The Ultra 5 336H dominates in every Cinebench test, all floating point math, encryption, extended instructions, prime number finding, physics, multithread, and random string sorting. This makes it the stronger choice for rendering, scientific computing, encryption workloads, and any task that benefits from parallel floating-point execution. Its 16 physical cores and larger per-core cache appear to drive these results.

The i7-14701E wins in Passmark single thread, integer math, and data compression. The 7.3% single-thread advantage, driven by its 5.40 GHz boost clock, makes it preferable for lightly threaded applications that depend on raw clock speed. The 31% lead in integer math suggests strength in general-purpose computing, database operations, and certain types of code compilation. The narrow data compression win, just 0.9%, shows comparable performance in that specific workload.

The overall average benchmark scores reflect the Ultra 5 336H's broader dominance. Its average score is 34485, while the i7-14701E sits at 33206. The percentile rankings confirm the gap: the Ultra 5 336H ranks in the 84th percentile of all CPUs, while the i7-14701E is in the 83rd. The nearest rivals for each processor show similar positioning. The i7-14701E sits within 0.4% of the AMD Ryzen 7 7745HX and the Intel Core i7-13650HX, while the Ultra 5 336H is within 0.8% of the AMD Ryzen AI 7 350 and 0.7% of the AMD Ryzen 7 3700X.
