Intel Core i7-12650HX vs Intel Core Ultra 5 225H Comparison

The Intel Core Ultra 5 225H and Intel Core i7-12650HX are both 14-core mobile processors, but they represent different generations and design philosophies. The Ultra 5 225H is built on a modern 3 nm process with a lower 28 W TDP, while the i7-12650HX is a 10 nm part with a 55 W TDP and 20 threads. Benchmark results show a clear split in workload preferences, with the newer chip dominating most tests but the older HX part holding its ground in specific scenarios.

Head-to-Head Benchmarks

The most striking difference appears in Cinebench R23, where the older i7-12650HX takes a commanding lead. In the multi-core test, the i7 scores 19043 against the Ultra 5's 14629.5, a 23.2% advantage. The single-core result is even more lopsided: 2688 versus 1969, giving the i7 a 26.7% edge. This pattern reverses sharply in earlier Cinebench versions. In R15 multi-core, the Ultra 5 wins with 2397.5 versus 1919, a 24.9% margin, and in R20 multi-core it leads 10041 to 7998, a 25.5% gap. The single-core results in R20 also favor the Ultra 5 by 25.6% (1417 versus 1128), and in R15 single-core the margin is 6.9% (288.5 versus 270). The data suggests these chips respond very differently to the specific workloads each Cinebench version stresses.

Outside of Cinebench, the Ultra 5 225H dominates the PassMark suite. The biggest win comes in the prime number search test, where the Ultra 5 scores 220 versus the i7's 74, a massive 197.3% advantage. Floating point math also goes heavily to the Ultra 5: 86540 versus 58426, a 48.1% lead. Data encryption shows a 39.8% edge (21428 versus 15325), and extended instructions follow closely at 38.2% (21915 versus 15856). The physics test gives the Ultra 5 a 62.9% advantage (1877 versus 1152). Multithread performance favors the Ultra 5 by 24.6% (28119 versus 22573), and single-thread performance is 17.1% better (4258 versus 3637). Data compression and random string sorting also go to the Ultra 5, with margins of 6.3% and 13.3% respectively.

The i7-12650HX does have one notable PassMark victory besides Cinebench R23. In integer math, it scores 81810 against the Ultra 5's 68520, a 16.2% advantage. That is a meaningful result for workloads that depend on integer operations. Overall, the Ultra 5 wins 14 of the 17 head-to-head tests, with the i7 taking only 3.

Where Each One Wins

The Intel Core Ultra 5 225H is the clear winner in most modern, short-duration workloads. Its PassMark results indicate strong performance in encryption, physics simulation, and floating point operations. The 39.8% lead in data encryption and 48.1% lead in floating point math suggest it handles security-related tasks and scientific calculations with ease. The massive 197.3% advantage in prime number searching points to excellent performance in workloads that stress integer-heavy algorithms with high branch prediction demands. The 62.9% physics score improvement also makes it the better choice for physics-based simulations in engineering or gaming contexts.

The i7-12650HX wins where sustained multi-threaded performance matters most. Its Cinebench R23 results, both multi-core (23.2% ahead) and single-core (26.7% ahead), indicate it can sustain high clock speeds under longer render or encoding workloads. The 16.2% integer math advantage also matters for tasks like compression, encryption, or database operations that rely heavily on integer arithmetic. The i7's 20 threads versus 14 threads give it a structural advantage in heavily threaded applications that can use all available threads.

For general productivity, the Ultra 5 225H leads in PassMark multithread by 24.6% and single-thread by 17.1%, making it the stronger all-rounder. However, the i7's Cinebench R23 dominance suggests that specific rendering workloads will run faster on the older chip. The choice depends on whether the workload is more like Cinebench R23 (long, sustained render) or more like the PassMark suite (varied, shorter tasks).

The Verdict

The data points to different buyers for each chip. The Intel Core Ultra 5 225H is the better choice for users who run a mix of everyday applications, security tools, physics simulations, and floating-point-heavy software. Its wins in 14 out of 17 benchmarks, including a 24.6% lead in multithread and a 17.1% lead in single-thread PassMark scores, make it the more versatile processor. The 39.8% encryption advantage and 48.1% floating point lead are particularly compelling for professionals working with cryptography, financial modeling, or scientific computing.

The Intel Core i7-12650HX is the pick for sustained rendering workloads. The 23.2% Cinebench R23 multi-core advantage and 26.7% single-core advantage show it can deliver higher performance in long-running render tasks. The 16.2% integer math lead also helps with database or compression work. However, its lower scores in nearly every other benchmark mean it is not the better all-rounder. The i7's higher 55 W TDP also suggests it will draw more power, though the fact pack does not provide efficiency metrics to quantify this.

Users who prioritize the latest process node and lower power draw should lean toward the Ultra 5 225H. Its 3 nm process and 28 W TDP represent a newer design. Those who need maximum Cinebench R23 performance in a laptop should consider the i7-12650HX, despite its older 10 nm node and higher TDP. The i7 also has an unlocked multiplier, which could allow overclocking in supported systems, a feature the Ultra 5 lacks.

Architecture Differences

The two chips come from different Intel architectures. The Ultra 5 225H is based on Arrow Lake, specifically the Arrow Lake-H codename, part of the Core Ultra Series 2. It uses a 3 nm process from TSMC. The i7-12650HX is based on Alder Lake, specifically Alder Lake-HX, and uses a 10 nm process from Intel's own foundries. The die size is also different, with the i7 measuring 215 mm² while the Ultra 5 has no listed die size.

Cache configurations differ significantly. The Ultra 5 has 192 KB of L1 cache per core, 3 MB of L2 per core, and 18 MB of shared L3 cache. The i7 has 80 KB of L1 per core, 1.25 MB of L2 per core, and a larger 24 MB of shared L3 cache. The i7's larger L3 cache likely helps its sustained performance, while the Ultra 5's larger per-core L1 and L2 caches may help with more varied workloads.

The integrated graphics differ as well. The Ultra 5 features Arc Graphics 130T, while the i7 has UHD Graphics 770. The memory support also varies: the Ultra 5 supports DDR5 and LPDDR5X, while the i7 supports DDR4 and DDR5. The Ultra 5 has a memory bandwidth of 102.4 GB/s, while the i7 has no listed memory bandwidth figure. PCIe support is another distinction, with the Ultra 5 offering Gen 5 with 8 lanes and the i7 offering Gen 5 with 20 lanes.

The release dates show the generational gap. The Ultra 5 was released on 2025-01-12, while the i7 came out on 2022-05-09. Both are currently in active production. The Ultra 5 has a part number of SRQAM, while the i7 has no listed part number.

Specification Differences

The most obvious specification difference is the thread count. The Ultra 5 225H has 14 threads, while the i7-12650HX has 20 threads. Both have 14 cores. The base clock speeds are listed differently, with the Ultra 5 at 1.70 GHz and the i7 at 2000.00 MHz, which is equivalent to 2.00 GHz. The boost clocks are closer, with the Ultra 5 at 4.90 GHz and the i7 at 4.70 GHz.

TDP is a major differentiator. The Ultra 5 draws 28 W, while the i7 draws 55 W. This makes the Ultra 5 more power-efficient on paper, though the fact pack does not include efficiency benchmarks. The sockets differ: the Ultra 5 uses Intel BGA 2049, while the i7 uses Intel BGA 1964. This means they are not interchangeable on the same motherboard.

The process node, as noted, is 3 nm for the Ultra 5 and 10 nm for the i7. The i7 has an unlocked multiplier, while the Ultra 5 does not. The i7 also has a larger L3 cache (24 MB versus 18 MB). The Ultra 5 supports LPDDR5X memory, which the i7 does not. The i7 supports DDR4 memory, which the Ultra 5 does not. Finally, the i7 has 20 PCIe Gen 5 lanes, while the Ultra 5 has only 8 lanes. These specification differences explain much of the benchmark behavior seen in the head-to-head results.
