Intel Core i7-14700F vs Intel Core Ultra 5 235HX Comparison

Head-to-Head Benchmarks

The benchmark data splits these two processors into distinct profiles. Across the 17 recorded comparisons, the Intel Core i7-14700F claims 10 wins, while the Intel Core Ultra 5 235HX takes 7. The margins, however, tell a more nuanced story than the win count.

Starting with the Cinebench suite, the i7-14700F edges ahead in every single test, but by remarkably consistent margins. In Cinebench R15 multicore, it scores 3540 against 3500, a 1.1% lead. The single-core R15 result is similarly tight at 499 versus 494, a 1% advantage. Moving to R20, the multicore test shows 14751 against 14587 (1.1% ahead), and single-core shows 2082 versus 2059 (1.1% ahead). The R23 results repeat the pattern exactly: multicore 35122 versus 34731, single-core 4958 versus 4903, both at 1.1% deltas. The PassMark multithread test also lands in this narrow band, with 41317 versus 40849, again 1.1% apart. These are not dominant victories; they indicate near-parity in sustained all-core rendering workloads, with the desktop chip holding a slight but consistent edge.

The larger wins appear in integer-heavy and data-oriented workloads. The most dramatic gap is in PassMark integer math, where the i7-14700F scores 155808 against 97177 for the Ultra 5 235HX, a commanding 60.3% advantage. Data compression also favors the desktop part heavily: 505885 versus 426417, an 18.6% lead. Random string sorting goes to the i7 as well, 55918 versus 50929, a 9.8% margin. These results point to a clear strength in workloads that depend on wide integer execution and memory subsystem throughput.

The Ultra 5 235HX answers with its own set of wins, concentrated in different areas. The largest is in prime number finding, where it scores 361 versus 176, a 51.2% advantage. Floating-point math goes decisively to the mobile chip: 129819 versus 107005, a 17.6% lead. Extended instructions show a 17.9% gap in favor of the Ultra 5 (34808 versus 28564), and data encryption favors it by 7.8% (32697 versus 30144). Single-thread PassMark also goes to the Ultra 5 at 4683 versus 4257, a 9.1% edge, and physics follows with 2550 versus 2455, a 3.7% margin. These wins suggest the newer architecture brings meaningful improvements to specific instruction paths and scalar efficiency.

The overall average benchmark scores reflect the split. The i7-14700F sits at 53620, the Ultra 5 235HX at 52073, a difference of roughly 3% in favor of the desktop chip. Both processors land at the 91st percentile among all CPUs in the database, meaning they occupy the same tier of overall performance despite their different strengths.

Architecture Differences

The two chips come from fundamentally different design generations. The Intel Core i7-14700F uses Raptor Lake architecture on a 10 nm process from Intel's own foundry, with a die size of 257 mm². The Intel Core Ultra 5 235HX uses Arrow Lake architecture on a 3 nm process manufactured by TSMC, with a die size of 243 mm² and 17,800 million transistors. The shift to TSMC's node allows the Ultra 5 to pack a denser design into a slightly smaller die.

Core configurations diverge significantly. The i7-14700F offers 20 cores and 28 threads, while the Ultra 5 235HX provides 14 cores and 14 threads. The desktop part relies on Hyper-Threading to reach 28 threads from 20 physical cores; the mobile part has no thread doubling, matching threads to cores exactly. This explains the i7's advantage in multithreaded integer workloads, as it can schedule nearly twice as many threads.

Cache hierarchies also differ. The i7-14700F uses 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra 5 235HX uses 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The Ultra 5 has larger per-core caches, which aligns with its stronger single-thread and floating-point results, while the i7 has a larger total L3 pool for its 20 cores.

Clock speeds favor the desktop chip at the top end. The i7-14700F has a base clock of 2.10 GHz and a boost of 5.40 GHz. The Ultra 5 235HX starts higher at 2.90 GHz base but boosts to 5.10 GHz. The higher boost on the i7 contributes to its narrow Cinebench single-core wins, though the Ultra 5 compensates with architectural efficiency in other single-thread tests.

Memory support differs as well. The i7-14700F supports both DDR4 and DDR5 in dual-channel configuration, while the Ultra 5 235HX supports DDR5 only. The database lists a memory bandwidth of 102.4 GB/s for the Ultra 5, while the i7 has no recorded bandwidth figure. The i7 supports ECC memory; the Ultra 5 does not. PCIe connectivity also differs: the i7 provides Gen 5 with 16 CPU lanes, while the Ultra 5 provides Gen 5 with 20 CPU lanes.

The integrated graphics situation is one-sided. The i7-14700F has no integrated graphics, listed as N/A. The Ultra 5 235HX includes Arc Xe-LPG Graphics with 48 execution units. The sockets and market segments reflect their intended roles: the i7 uses Intel Socket 1700 for desktop builds, while the Ultra 5 uses Intel BGA 2114, a soldered mobile package. The Ultra 5 is also multiplier unlocked, while the i7-14700F is not. Release dates place the i7 in January 2024 and the Ultra 5 in January 2025, roughly a year apart.

Where Each One Wins

The Intel Core i7-14700F is the choice for integer-heavy throughput. Its 60.3% lead in PassMark integer math over the Ultra 5 235HX is the single largest gap in the entire comparison. Data compression also favors it by 18.6%, and random string sorting by 9.8%. These are the workloads where the 20-core, 28-thread configuration with 33 MB of shared L3 pays off. The multithread PassMark result, while only 1.1% ahead, still confirms the i7 as the stronger general multi-core chip. For rendering workloads measured by Cinebench, the i7 wins every test, though the margins are small enough that the Ultra 5 remains competitive. The i7 also supports ECC memory and both DDR4 and DDR5, which broadens its compatibility with existing platforms and server-adjacent use cases.

The Intel Core Ultra 5 235HX wins in scalar efficiency and specialized instruction paths. Its 51.2% lead in prime number finding suggests superior branch handling and integer division performance. The 17.6% lead in floating-point math and 17.9% lead in extended instructions indicate the Arrow Lake architecture executes certain instruction classes more efficiently. Data encryption runs 7.8% faster, and physics simulation is 3.7% ahead. The PassMark single-thread score favors the Ultra 5 by 9.1%, which is notable given the i7's higher 5.40 GHz boost clock versus 5.10 GHz on the Ultra 5. The mobile chip also brings integrated graphics, 20 PCIe Gen 5 lanes, a higher base clock, and a lower 55 W TDP. Its larger per-core caches (192 KB L1, 3 MB L2) support its efficiency advantages.

The Verdict

The data defines two clear buyer profiles. Choose the Intel Core i7-14700F if the workload is dominated by integer math, data compression, string sorting, or multithreaded rendering. The 60.3% integer math advantage and 18.6% compression lead are decisive. The 20-core, 28-thread layout, 33 MB L3 cache, DDR4 compatibility, and ECC support make it the more flexible desktop workhorse. Its Cinebench wins, while narrow, are consistent across every version of the test, so there is no rendering scenario where the Ultra 5 overtakes it. The launch MSRP for the i7-14700F is $359, recorded once in the database.

Choose the Intel Core Ultra 5 235HX if the workload involves heavy floating-point math, prime number finding, encryption, extended instructions, or scalar single-threaded tasks with power constraints mattering alongside performance. The 51.2% prime number lead, 17.9% floating-point math and 17.9% extended instruction advantages are the reasons. Its integrated graphics, 20 PCIe Gen 5 lanes, unlocked multiplier, higher base clock, and larger per-core caches fit mobile and laptop platforms. The 91st percentile ranking for both chips means either will sit near the top of the database, but the choice between them comes down to thread scaling versus architectural efficiency.

For users building a desktop system on a 1700 socket with DDR4 or DDR5, the i7-14700F is the straightforward pick. For those on a mobile platform requiring integrated graphics and lower power draw, the Ultra 5 235HX is the only option of the two, and its benchmark profile shows it gives up little in overall multithreaded performance while winning several specialized categories. The 1.1% margins in Cinebench and multithread PassMark are close enough that real-world differences would be difficult to perceive in most rendering tasks. The decisive factors are the large integer advantage on the i7 side and the large floating-point and scalar advantages on the Ultra 5 side.
