Q: Do these processors have unlocked multipliers for overclocking?

A: No, both the 235H and 225F have the multiplier locked (multiplierUnlocked: false). Overclocking is not officially supported on either chip.

Architecture Differences

Both processors are built on the Arrow Lake architecture, but they use different variants: the 235H uses Arrow Lake-H (mobile), and the 225F uses Arrow Lake-S (desktop). The process node is identical at 3 nm from TSMC, but the desktop part has published transistor and die size figures: 17,800 million transistors on a 243 mm² die. The mobile part does not list these specifications.

The core configuration is the most significant architectural difference. The 235H packs 14 cores and 14 threads, while the 225F has 10 cores and 10 threads. This gives the mobile chip a 40% core advantage, which directly impacts multi-threaded workloads. However, the desktop chip compensates with a higher base clock (3.30 GHz vs 2.40 GHz) and nearly matching boost clock (4.90 GHz vs 5.00 GHz). The 225F also has a larger L3 cache at 20 MB versus 18 MB on the 235H.

The memory controllers differ in supported types: the 235H supports DDR5 and LPDDR5X, making it more flexible for mobile designs, while the 225F is limited to DDR5. Both run dual-channel with identical 102.4 GB/s bandwidth. PCIe connectivity is another major split: the 225F provides 20 Gen 5 lanes (CPU only), while the 235H offers only 8 Gen 5 lanes. This makes the desktop chip far more suitable for multi-GPU or high-bandwidth expansion setups.

The 225F has no integrated graphics, which is typical for desktop "F" series parts. The 235H includes Arc Graphics 140T, providing a complete mobile solution without needing a discrete GPU. The TDP difference is stark: 28 W for the mobile chip versus 65 W for the desktop chip. This reflects the thermal and power constraints of laptops versus desktops. The 225F's launch MSRP is $231, which can be stated once.

Head-to-Head Benchmarks

The head-to-head data shows the 225F winning 11 of 17 benchmarks, while the 235H takes 6 wins. The margin of victory varies dramatically by workload. The most extreme result is in Cinebench R23 single-core, where the 235H scores 3613 versus 1893 for the 225F—a massive 90.9% advantage. Even more striking, the 235H wins Cinebench R23 multi-core with 25598 versus 16467, a 55.5% lead. These R23 results are the 235H's strongest showing and are outliers compared to the rest of the data.

In contrast, the 225F wins most Cinebench and PassMark tests by narrow margins. In Cinebench R15 multi-core, the 225F scores 2660 versus 2580 for the 235H, a 3% edge. Cinebench R20 multi-core shows 11059 versus 10751, a 2.8% lead. The 225F also wins Cinebench R20 single-core (1561 vs 1517, 2.8%). The PassMark results follow a similar pattern: the 225F wins data compression (310843 vs 301979, 2.9%), multithread (31004 vs 30091, 2.9%), random string sorting (37325 vs 36208, 3%), and single-thread (4397 vs 4359, 0.9%).

The 225F's biggest wins outside of R23 come in specific PassMark tests. It beats the 235H by 16.7% in extended instructions (28027 vs 23354), by 18.3% in physics (2430 vs 1985), and by 32.1% in find prime numbers (352 vs 239). The 235H takes narrower wins in data encryption (23121 vs 22648, 2.1%), floating point math (93509 vs 92554, 1%), and integer math (74247 vs 66417, 11.8%). The 235H also wins Cinebench R15 single-core by a large margin: 364 versus 287, a 26.8% difference.

The Verdict

The data presents a split decision. If your primary workload is Cinebench R23—whether single-core or multi-core—the Intel Core Ultra 5 235H is the clear choice, with leads of 90.9% and 55.5% respectively. These are dramatic margins that suggest the mobile chip's architecture and core count are better optimized for this specific rendering workload. The 235H also wins integer math by 11.8%, indicating strength in certain computational tasks.

For almost everything else, the Intel Core Ultra 5 225F is the better performer. It wins 11 of 17 benchmarks, including all PassMark tests except data encryption, floating point math, and integer math. The margins are typically small (1-3%), but consistent. The 225F also has a major hardware advantage: 20 PCIe Gen 5 lanes versus 8 on the 235H, making it vastly more expandable for desktop use. The lack of integrated graphics is a non-issue for desktop builders who will use a discrete GPU anyway.

The 225F's higher TDP (65 W vs 28 W) and desktop socket (Socket 1851 vs BGA 2049) mean it is designed for sustained performance in a desktop chassis with proper cooling. The 235H's mobile design prioritizes power efficiency and package integration, evidenced by its Arc Graphics 140T. The 225F also carries a launch MSRP of $231, though the 235H has no listed launch MSRP. Ultimately, the 225F is the more versatile and consistent performer, while the 235H is a specialist that excels in Cinebench R23 workloads.

Specification Differences

The two processors differ in nearly every physical and electrical specification. The 235H has 14 cores and 14 threads, while the 225F has 10 cores and 10 threads. Base clocks are 2.40 GHz for the mobile chip and 3.30 GHz for the desktop chip. Boost clocks are closer: 5.00 GHz for the 235H versus 4.90 GHz for the 225F. TDP is a major differentiator: 28 W for the 235H and 65 W for the 225F.

The sockets are incompatible: the 235H uses Intel BGA 2049 (soldered mobile), while the 225F uses Intel Socket 1851 (desktop LGA). The L3 cache differs slightly: 18 MB shared on the 235H versus 20 MB shared on the 225F. Memory support is broader on the mobile chip (DDR5 and LPDDR5X) versus DDR5-only on the desktop chip. PCIe connectivity is dramatically different: the 225F provides 20 Gen 5 lanes, while the 235H provides only 8 Gen 5 lanes.

Integrated graphics are present on the 235H (Arc Graphics 140T) but absent on the 225F (N/A). The 225F has published transistor count (17,800 million) and die size (243 mm²), while the 235H does not list these. Both use the same 3 nm TSMC process, dual-channel memory bus, 102.4 GB/s bandwidth, and do not support ECC memory. Neither has an unlocked multiplier. The release dates are close: 2025-01-06 for the 225F and 2025-01-12 for the 235H. The 225F has a launch MSRP of $231; the 235H has none.

Where Each One Wins

The Intel Core Ultra 5 235H wins in Cinebench R23 multi-core (25598 vs 16467, 55.5% lead) and Cinebench R23 single-core (3613 vs 1893, 90.9% lead). It also wins Cinebench R15 single-core (364 vs 287, 26.8%) and PassMark integer math (74247 vs 66417, 11.8%). Smaller wins include PassMark data encryption (23121 vs 22648, 2.1%) and floating point math (93509 vs 92554, 1%). This makes the 235H the pick for Cinebench R23 rendering tasks and workloads that rely heavily on integer math.

The Intel Core Ultra 5 225F wins in Cinebench R15 multi-core (2660 vs 2580, 3%), Cinebench R20 multi-core (11059 vs 10751, 2.8%), and Cinebench R20 single-core (1561 vs 1517, 2.8%).
