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

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the Intel Core Ultra 7 265F across every shared benchmark in the database. The AMD Ryzen AI 9 HX 375 does not secure a single win in the head-to-head comparisons, with the Intel part taking all 15 recorded tests. The margins are substantial in most cases, though the gap narrows in a few specific workloads.

The largest single-core advantage appears in Cinebench R23 single-core, where the Intel chip scores 5,926 against the AMD's 1,988, a delta of -66.5% for the AMD part. The same pattern holds in Cinebench R15 single-core, with Intel at 597 versus AMD at 301, a -49.6% difference. These results indicate a major architectural advantage in lightly threaded workloads, likely stemming from higher clock speeds and a different core design.

Multi-core performance also favors Intel significantly. In Cinebench R23 multi-core, the Intel Core Ultra 7 265F posts 41,980 while the AMD Ryzen AI 9 HX 375 manages 21,812, a -48% delta. Cinebench R15 multi-core shows a -21.2% gap, with Intel at 4,231 and AMD at 3,334. This is a nearly two-to-one performance ratio in the newer Cinebench version, despite the AMD part having 12 cores and 24 threads versus Intel's 20 cores and 20 threads.

PassMark tests reinforce the trend. The largest margin is in find prime numbers, where Intel scores 416 against AMD's 122, a -70.7% delta.

Random string sorting favors Intel at 62,439 versus 44,552, a -28.6% gap. PassMark multithread shows Intel at 49,410 versus 32,916, a -33.4% delta.

The average benchmark score in the database confirms the overall positioning. The Intel Core Ultra 7 265F has an average score of 64,438, placing it at the 93rd percentile among all CPUs. The AMD Ryzen AI 9 HX 375 has an average score of 46,030, at the 89th percentile. The Intel part's nearest rivals include the Intel Core Ultra 7 265 at 64,640 (-0.3% delta) and the AMD EPYC 4464P at 64,823 (-0.6% delta), indicating it sits in a competitive desktop performance tier. The AMD part's nearest rivals include the Intel Core Ultra 5 235 at 46,062 (-0.1% delta) and the Intel Core i9-13900HX at 46,098 (-0.1% delta), showing it is statistically tied with those chips.

Architecture Differences

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

Core counts differ sharply. The AMD part has 12 cores and 24 threads, indicating simultaneous multithreading. The Intel part has 20 cores and 20 threads, with no hyperthreading. This means Intel relies on raw core count for multi-threaded performance, while AMD uses fewer cores with two threads each. Despite the thread count disadvantage, Intel's 20 physical cores deliver higher multi-core scores in every recorded benchmark.

Cache hierarchies are also distinct. The AMD chip has 80 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Intel's larger L3 cache, at 30 MB versus 16 MB, likely contributes to its performance in data-heavy workloads, though the benchmark data does not isolate cache effects.

Clock speeds favor Intel in both base and boost. The AMD part has a 2.00 GHz base clock and a 5.10 GHz boost clock. The Intel part has a 2.40 GHz base clock and a 5.30 GHz boost clock. The higher boost clock on Intel aligns with its single-core benchmark wins, while the higher base clock helps sustained multi-core performance.

Memory support differs. Both support DDR5, but the AMD part also supports LPDDR5X. Memory bandwidth is higher on Intel at 102.4 GB/s versus 89.6 GB/s on AMD. Both use dual-channel memory buses. PCIe support favors Intel with Gen 5 and 20 lanes, while AMD uses Gen 4 with 16 lanes. Neither supports ECC memory.

The integrated graphics situation is a major differentiator. The AMD Ryzen AI 9 HX 375 includes a Radeon 890M iGPU, while the Intel Core Ultra 7 265F has no integrated graphics (N/A). This reflects their market positions: AMD is a mobile processor with an iGPU for laptop use, while Intel is a desktop processor designed for systems with discrete graphics.

Market segments and sockets confirm the split. AMD uses Socket FP8 and is a mobile chip. Intel uses Socket 1851 and is a desktop chip. The TDP values reflect this: AMD at 28 watts, Intel at 65 watts. The production status for both is active, with AMD releasing on 2024-06-30 and Intel on 2025-01-06.

Where Each One Wins

Based on the benchmark data, the Intel Core Ultra 7 265F wins in every measured category. There is no recorded workload where the AMD Ryzen AI 9 HX 375 outperforms it. The largest margins are in prime number finding (-70.7%), single-core Cinebench R23 (-66.5%), and floating point math (-56.8%). These are compute-intensive tasks that rely heavily on raw core performance and clock speed, where Intel's 5.30 GHz boost clock and 20 cores give it a clear edge.

The smaller margins, such as integer math (-11.8%) and single-thread PassMark (-18.6%), suggest areas where the AMD part is more competitive. Integer math may benefit from AMD's 24 threads, which allow better scheduling of parallel integer operations. The single-thread PassMark score, while still favoring Intel, shows the AMD chip is not far behind in general single-threaded tasks, only 18.6% slower.

For users running Cinebench-style rendering workloads, the Intel part delivers nearly double the multi-core score. This positions it strongly for 3D rendering, video encoding, and other heavily threaded content creation tasks. The data compression and encryption tests, where Intel leads by 20.1% and 47.3% respectively, indicate advantages in file archiving, database workloads, and security applications.

The AMD part's place in the database is not without merit. Its 89th percentile ranking and average score of 46,030 place it alongside the Intel Core i9-13900HX and Intel Core Ultra 5 235, both within 0.1% delta. This means the AMD chip is competitive with those parts, but the Intel Core Ultra 7 265F sits in a higher performance class, as shown by its 93rd percentile and average score of 64,438.

The Verdict

The benchmark data is unambiguous. The Intel Core Ultra 7 265F outperforms the AMD Ryzen AI 9 HX 375 in every recorded test, with margins ranging from 11.8% in integer math to 70.7% in prime number finding. The Intel part's 93rd percentile ranking and average score of 64,438 place it in a higher performance tier than the AMD part's 89th percentile and 46,030 average.

The Intel Core Ultra 7 265F is the choice for desktop users seeking maximum multi-core and single-core performance. Its 20 cores, 5.30 GHz boost clock, 30 MB L3 cache, and 102.4 GB/s memory bandwidth deliver consistent wins across rendering, encryption, math, and sorting workloads. The lack of integrated graphics is a non-issue for desktop systems with discrete GPUs, and its 65 watt TDP is reasonable for a desktop part.

The AMD Ryzen AI 9 HX 375 is a mobile processor with integrated graphics, designed for laptops. Its 28 watt TDP and Radeon 890M iGPU make it suitable for portable systems, but the performance data shows it cannot compete with the Intel desktop part in raw compute. Its 24 threads may help in some integer-heavy parallel tasks, but the 11.8% deficit in integer math still favors Intel.

Users who need a processor for a desktop workstation with a discrete GPU should pick the Intel Core Ultra 7 265F based on these measurements. Users who require an integrated GPU and mobile form factor should consider the AMD Ryzen AI 9 HX 375, but they should expect significantly lower performance in every benchmark category recorded in the database. The data does not support any scenario where the AMD part wins a performance comparison against the Intel part.
