Intel Core i7-13705H vs Intel Core Ultra 5 225H Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split: the Intel Core Ultra 5 225H wins 14 of 17 recorded comparisons, while the Intel Core i7-13705H takes 3. The most dramatic differences appear in Cinebench R20 and R15 multi-core tests, where the Ultra 5 225H leads by roughly a third. In Cinebench R20 multi-core, the Ultra 5 scores 10041 against 6719 for the i7-13705H, a 33.1% advantage. The R15 multi-core result mirrors this pattern: 2397.5 versus 1612, a 32.8% gap. Single-core Cinebench R20 also favors the Ultra 5 by 33.1%, with 1417 points against 948.

The i7-13705H fights back in Cinebench R23. It posts 15998 in multi-core versus 14629.5 for the Ultra 5, a 9.4% win. Single-core R23 shows a 14.7% edge for the i7-13705H, scoring 2258 against 1969. This reversal suggests the older chip retains an advantage in sustained workloads measured by the R23 test, even as the newer part dominates other Cinebench versions.

Passmark results reinforce the Ultra 5's overall lead. Integer math is the i7-13705H's strongest counter: 85927 versus 68520, a 25.4% margin. However, the Ultra 5 wins the remaining Passmark categories decisively. Floating point math goes to the Ultra 5 at 86540 versus 63064, a 27.1% gap. Prime number finding shows a 47.3% advantage (220 versus 116), the largest proportional win in the entire comparison. Extended instructions favor the Ultra 5 by 27.9% (21915 versus 15810). Data encryption is 23.8% faster on the Ultra 5 (21428 versus 16324), and data compression edges out at 3.4% (283451 versus 273720).

The multi-thread Passmark score puts the Ultra 5 ahead by 13% (28119 versus 24460), and random string sorting also shows a 13% gap (33654 versus 29285).

Both processors sit at the 82nd percentile among all CPUs, indicating similar standing in the broader market.

Architecture Differences

The two processors come from different Intel design eras. The i7-13705H uses Raptor Lake architecture, built on a 10 nm process at Intel's own foundry. The Ultra 5 225H moves to Arrow Lake architecture on a 3 nm node manufactured by TSMC. This process shrink likely explains the Ultra 5's efficiency characteristics, though specific power figures beyond TDP are not recorded.

Both chips have 14 cores, but thread counts diverge: the i7-13705H supports 20 threads, while the Ultra 5 225H has 14 threads. This reflects a design change in how the newer processor handles simultaneous multithreading. Cache hierarchies differ substantially. The i7-13705H allocates 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. The Ultra 5 225H offers larger per-core caches: 192 KB L1 and 3 MB L2, but a smaller 18 MB shared L3. The die size for the i7-13705H is recorded at 257 mm², while no die size is listed for the Ultra 5.

Memory support changes as well. The i7-13705H accepts DDR4 and DDR5, while the Ultra 5 225H supports DDR5 and LPDDR5X. Both use dual-channel memory buses. The Ultra 5 records a memory bandwidth of 102.4 GB/s; no bandwidth figure is available for the i7-13705H. Neither processor supports ECC memory. PCIe configuration is identical: Gen 5 with 8 lanes from the CPU.

Integrated graphics differ. The i7-13705H pairs with Iris Xe Graphics 96EU, while the Ultra 5 225H uses Arc Graphics 130T. Clock speeds also separate the two: the i7-13705H has a 2.40 GHz base clock and 5.00 GHz boost, versus 1.70 GHz base and 4.90 GHz boost for the Ultra 5. The sockets are incompatible: Intel BGA 1744 for the i7-13705H, Intel BGA 2049 for the Ultra 5. Both ship with locked multipliers and target the mobile segment. The i7-13705H launched on January 3, 2023, with the Ultra 5 225H following on January 12, 2025.

The Verdict

The data points to the Intel Core Ultra 5 225H as the stronger performer in most measured scenarios. It wins 14 of 17 head-to-head benchmarks, including all Cinebench R15 and R20 tests, plus the majority of Passmark workloads. Its gains are substantial in compute-heavy tasks: 33.1% in Cinebench R20 multi-core, 27.9% in extended instructions, and 27.1% in floating point math. The Ultra 5 also operates at a lower TDP of 28 W versus 45 W for the i7-13705H, a meaningful efficiency advantage for mobile systems.

The i7-13705H retains specific strengths. It wins Cinebench R23 multi-core by 9.4% and single-core by 14.7%, and it dominates integer math with a 25.4% margin. These wins suggest the older chip handles certain integer-heavy and R23-specific workloads better. However, the overall score distribution heavily favors the Ultra 5, and the two chips sit at the same 82nd percentile, meaning the i7-13705H's wins do not translate into a higher overall ranking.

For buyers prioritizing raw multi-threaded performance across the Cinebench suite and Passmark, the Ultra 5 225H is the choice. For those whose workloads align with Cinebench R23 or integer math operations, the i7-13705H offers a measurable advantage. The i7-13705H also has a launch MSRP of $502, while the Ultra 5's price is not recorded, so direct cost comparison is not possible from the data.

Where Each One Wins

The Intel Core Ultra 5 225H wins across most benchmark categories. Cinebench R15 and R20, both multi-core and single-core, go to the Ultra 5 with margins from 21.3% to 33.1%. Passmark data compression, encryption, extended instructions, prime numbers, floating point math, multi-thread, physics, random string sorting, and single-thread all favor the Ultra 5. Its largest win is prime number finding at 47.3%, followed by Cinebench R20 multi-core and single-core at 33.1%. The Ultra 5 also edges out the i7-13705H in physics by a narrow 1.2% margin.

The Intel Core i7-13705H wins Cinebench R23 multi-core by 9.4% and single-core by 14.7%. Its Passmark integer math score leads by 25.4%. These three wins represent the older chip's clear domains: the R23 workload and integer arithmetic. Notably, the i7-13705H has 20 threads versus 14 for the Ultra 5, yet it still loses most multi-threaded tests, suggesting the Ultra 5's per-core efficiency compensates for fewer threads. The i7-13705H's 24 MB L3 cache is larger than the Ultra 5's 18 MB, which may contribute to its R23 and integer math victories.

The overall average benchmark scores tell a nuanced story: 32076 for the i7-13705H against 31508 for the Ultra 5, a difference of only 1.8%. This near-parity in averages, combined with the Ultra 5's 14 test wins, indicates the newer processor achieves broader consistency while the older one excels in niche areas. Users with integer-heavy or R23-specific workloads might prefer the i7-13705H; those needing a well-rounded mobile processor with lower TDP should lean toward the Ultra 5 225H.
