AMD Ryzen AI 9 HX 375 vs Intel Core Ultra 7 265 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall result: the Intel Core Ultra 7 265 wins every single head-to-head benchmark in the comparison set, with 15 wins against zero for the AMD Ryzen AI 9 HX 375. The margins are not uniform, however, and the distribution of deltas reveals where each architecture is comparatively stronger or weaker.

The largest gap appears in Cinebench R23 single-core, where the Intel part scores 5960 against the AMD's 1988, a delta of -66.6% from the AMD perspective. That is a massive single-thread deficit. The Cinebench R23 multi-core result narrows the relative gap somewhat, with Intel at 42216 versus AMD at 21812, a -48.3% delta. The most extreme single gap in the entire set is PassMark find prime numbers: Intel scores 418, AMD scores 122, a -70.8% delta. Floating-point math also tilts heavily toward Intel, 172776 versus 75153, a -56.5% delta.

The closest contest is PassMark integer math, where Intel leads 134773 to 121754, a delta of only -9.7%. That is the only benchmark where the AMD part remains within 10% of the Intel result. PassMark single-thread shows a -17.5% delta (4689 versus 3867), and Cinebench R15 multi-core shows -21.6% (4255 versus 3334). Data compression sits at -22.6% (522983 versus 404918).

Mid-tier deltas dominate the rest. Extended instructions: Intel 41478, AMD 29269, -29.4%. Random string sorting: Intel 63833, AMD 44552, -30.2%. PassMark multithread: Intel 49682, AMD 32916, -33.7%. Physics: Intel 2923, AMD 1819, -37.8%. Data encryption: Intel 40456, AMD 20802, -48.6%. Cinebench R15 single-core: Intel 600, AMD 301, -49.8%.

The overall average benchmark score reflects the same direction: Intel records 64640, AMD records 46030, a difference of roughly 40%. The Intel part also holds a higher percentile ranking among all CPUs, 93 versus 89. The nearest rival data confirms the Intel position: its closest competitor, the AMD EPYC 4464P, sits at 64823 average score, only -0.3% above the Core Ultra 7 265. The AMD Ryzen AI 9 HX 375, by contrast, has nearest rivals clustered around a 46000 average, including the Intel Core Ultra 5 235 at 46062 (-0.1%) and the Intel Core i9-13900HX at 46098 (-0.1%). This places the AMD part in a different performance tier entirely.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 9 HX 375 uses the Zen 5 architecture under the Strix Point codename, built on a 4 nm TSMC process with a die size of 233 mm². It belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. The Intel Core Ultra 7 265 uses the Arrow Lake architecture, specifically Arrow Lake-S, built on a 3 nm TSMC process with a die size of 243 mm² and a transistor count of 17,800 million. The Intel part belongs to the Core Ultra Series 2 generation.

Core and thread counts differ substantially. AMD provides 12 cores and 24 threads, while Intel provides 20 cores and 20 threads. The AMD chip enables simultaneous multithreading, doubling thread count, while the Intel chip does not. Clock speeds also differ: AMD base clock is 2.00 GHz with a boost of 5.10 GHz; Intel base clock is 2.40 GHz with a boost of 5.30 GHz. The Intel part has the higher base and boost clocks.

Cache organization diverges as well. AMD uses 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. Intel uses 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The Intel cache hierarchy is larger at every level. Memory support shows AMD accepting both DDR5 and LPDDR5X, while Intel lists only DDR5. Both use dual-channel memory buses, but memory bandwidth favors Intel: 102.4 GB/s versus 89.6 GB/s.

PCIe connectivity differs by generation and lane count. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). The integrated graphics also differ: AMD uses the Radeon 890M, while Intel uses Arc Xe-LPG Graphics 32EU. Neither part supports ECC memory, and neither has an unlocked multiplier. The AMD part uses AMD Socket FP8, while the Intel part uses Intel Socket 1851. The AMD part is a mobile segment product; the Intel part is a desktop segment product. The Intel part has a launch MSRP of $394, while the AMD part has no recorded launch MSRP.

Production status is Active for both. Release dates differ by about six months: AMD released on 2024-06-30, Intel on 2025-01-06. Part numbers are 100-000001682 for AMD and SRQCX for Intel.

Where Each One Wins

Based strictly on the benchmark set, the Intel Core Ultra 7 265 wins every measured category. There is no single workload in the recorded data where the AMD Ryzen AI 9 HX 375 takes the lead. The closest AMD performance appears in PassMark integer math, where the delta is only -9.7%. This suggests the AMD design is least disadvantaged in integer-heavy scalar work, but it still loses.

The Intel part shows its largest advantages in tasks that stress single-thread performance and vector or cryptographic workloads. Prime number finding, floating-point math, data encryption, and Cinebench single-core all show deltas beyond -48%. These are workloads where the Intel core design, higher boost clock, and larger L1 and L2 caches provide clear benefits. The data suggests that any application relying heavily on floating-point throughput, encryption, or single-thread responsiveness will favor the Intel part by a wide margin.

The AMD part, despite losing every benchmark, does not collapse uniformly. In integer math, multithread, and data compression, the AMD chip stays within a range that is competitive in relative terms. Integer math at -9.7%, multithread at -33.7%, and data compression at -22.6% are the smaller deltas. These workloads tend to be less dependent on peak frequency and more dependent on sustained throughput and memory behavior. The AMD chip's 24 threads versus Intel's 20 threads does not translate into a win, but it likely limits the damage in throughput-oriented tests. The AMD part also carries a much lower TDP, 28 W versus 65 W, which is a relevant distinction for mobile platforms, though the benchmark data does not directly measure power efficiency.

The FAQ below addresses common questions that arise from the data.

The Verdict

The data points clearly in one direction. For any workload represented in the benchmark set, the Intel Core Ultra 7 265 delivers a higher score than the AMD Ryzen AI 9 HX 375. The Intel part wins all 15 head-to-head benchmarks, holds a 93rd percentile ranking versus the AMD's 89th, and records an average benchmark score about 40% higher.

The AMD Ryzen AI 9 HX 375 is a mobile processor with a 28 W TDP, 12 cores, and 24 threads. Its performance profile places it among rivals averaging around 46000, such as the Intel Core Ultra 5 235 and the Intel Core i9-13900HX. The Intel Core Ultra 7 265 is a desktop processor with a 65 W TDP, 20 cores, and 20 threads, and its average score of 64640 puts it in the company of server-class parts like the AMD EPYC 4464P and the AMD EPYC 9124. The two chips occupy different market segments and different performance tiers.

Users choosing between these two should base the decision on platform and segment, not on benchmark parity. The Intel part is the higher-performing processor in every recorded test, with particularly large margins in single-thread, floating-point, and encryption workloads. The AMD part, with its lower TDP and mobile socket, serves a different purpose. The benchmark data does not show any workload category where the AMD chip closes the gap to a competitive level, beyond integer math at -9.7%. On raw recorded performance, the Intel Core Ultra 7 265 is the clear winner.
