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

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core Ultra 7 265KF wins every single recorded comparison, 17 out of 17. The AMD Ryzen AI 9 HX 375 does not record a single victory in the head-to-head tests. The largest margin comes in Cinebench R23 single-core, where the Intel part scores 7021 against AMD's 1988, a delta of -71.7% from AMD's perspective. That is a massive gap in single-threaded performance, and it is not an isolated case.

In Cinebench R15 single-core, Intel leads 707 to 301 (-57.4%). The same pattern holds for multi-core workloads. Cinebench R23 multi-core shows Intel at 49736 versus AMD's 21812 (-56.1%). Cinebench R15 multi-core is closer in relative terms but still decisively Intel's: 5013 against 3334 (-33.5%). Geekbench results follow suit, with Intel ahead 22913 to 13957 in multi-core (-39.1%) and 2759 to 2084 in single-core (-24.5%).

PassMark tests reinforce the trend across every category. The smallest relative gap is in integer math, where Intel scores 143351 versus AMD's 121754 (-15.1%). Single-thread PassMark shows Intel at 4928 against AMD's 3867 (-21.5%). Every other PassMark workload shows Intel winning by at least 39%. Data compression: 666589 vs 404918 (-39.3%). Data encryption: 48198 vs 20802 (-56.8%). Extended instructions: 54513 vs 29269 (-46.3%). Floating-point math: 189431 vs 75153 (-60.3%). Multi-thread: 58518 vs 32916 (-43.8%). Physics: 3633 vs 1819 (-49.9%). Random string sorting: 79735 vs 44552 (-44.1%). Prime numbers: 486 vs 122 (-74.9%).

The average benchmark score tells the same story. The Intel Core Ultra 7 265KF averages 71910 across all recorded benchmarks, while the AMD Ryzen AI 9 HX 375 averages 46030. That is a 56.2% higher average for Intel. The Intel part also sits in the 94th percentile of all CPUs, compared to AMD's 89th percentile. For the AMD chip, its nearest rivals include the Intel Core Ultra 5 235 (delta of -0.1%), the AMD EPYC 4364P (0.1%), the Intel Core i9-13900HX (-0.1%), and the AMD EPYC 7303 (0.2%). For the Intel chip, its nearest rivals are the AMD Ryzen 7 8840HX (0.2%), the Intel Xeon 6517P (-0.6%), the Intel Xeon 6724P (-0.7%), and the Intel Xeon Platinum 8270 (0.8%). These rival comparisons confirm that the Intel part operates in a higher performance tier, competing with server-class Xeon processors, while the AMD part sits near mobile and older HX-class parts.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 9 HX 375 uses the Zen 5 architecture under the codename Strix Point, built on a 4 nm TSMC process. It is a 12-core, 24-thread part, meaning it uses simultaneous multithreading. Its L1 cache is 80 KB per core, L2 is 1 MB per core, and L3 is 16 MB. The base clock is 2.00 GHz with a boost clock of 5.10 GHz. The thermal design power is 28 W, and it uses the AMD Socket FP8. This is a mobile processor, released on 2024-06-30, with integrated Radeon 890M graphics. Memory support covers DDR5 and LPDDR5X over a dual-channel bus with 89.6 GB/s bandwidth. PCIe support is Gen 4 with 16 lanes (CPU only). The die size is 233 mm².

The Intel Core Ultra 7 265KF uses the Arrow Lake architecture, specifically the Arrow Lake-S codename, built on a 3 nm TSMC process. It has 20 cores and 20 threads, so it does not support hyper-threading. Each core has 192 KB of L1 and 3 MB of L2, with a shared 30 MB L3. The base clock is 3.90 GHz and boost reaches 5.50 GHz. The thermal design power is 125 W, and it uses the Intel Socket 1851. This is a desktop processor released on 2024-10-23 with no integrated graphics. It supports only DDR5 over a dual-channel bus with 102.4 GB/s bandwidth. PCIe support is Gen 5 with 20 lanes (CPU only). The die size is 243 mm², and the transistor count is 17,800 million. The multiplier is unlocked, confirming its overclocking-oriented KF designation.

The process node difference is one nanometer, with Intel on 3 nm and AMD on 4 nm, though both are fabricated by TSMC. The core count difference is significant: Intel has 20 cores versus AMD's 12, and Intel achieves this without SMT, relying on raw core count and higher clocks. The cache hierarchy also differs substantially, with Intel offering larger per-core L1 and L2 allocations and a nearly double L3 pool (30 MB versus 16 MB). Clock speeds favor Intel in both base and boost. The boost clock gap is 0.40 GHz, while the base clock gap is 1.90 GHz. The TDP gap is 97 W, reflecting Intel's desktop power envelope versus AMD's mobile efficiency target.

Where Each One Wins

Looking strictly at the recorded data, the Intel Core Ultra 7 265KF wins every benchmark category. There is no workload in the database where the AMD Ryzen AI 9 HX 375 posts a higher score. That said, the use cases are different based on the platform characteristics, not on benchmark victories. The AMD part is a mobile processor on Socket FP8 with integrated Radeon 890M graphics, so it fits systems where a discrete GPU is not mandatory and where power draw is limited to 28 W. The Intel part is a desktop processor with no integrated graphics, requiring a separate GPU, and its 125 W TDP suits a desktop chassis with adequate cooling.

The benchmark data indicates that the Intel part dominates in heavy multi-threaded rendering, as shown by Cinebench R23 multi-core (49736 vs 21812) and Cinebench R15 multi-core (5013 vs 3334). It also dominates in single-threaded responsiveness, as shown by Cinebench R23 single-core (7021 vs 1988) and Geekbench single-core (2759 vs 2084). PassMark workloads show Intel ahead in every computational category, from integer math (143351 vs 121754) to floating-point math (189431 vs 75153) to encryption (48198 vs 20802).

For the AMD part, the only practical advantage lies in its mobile form factor and integrated graphics, which allow operation without a discrete GPU and at a 28 W TDP. The database does not record any benchmark where the AMD chip wins, so any use-case advantage must be inferred from the socket, TDP, and iGPU presence, not from performance scores. The Intel part is clearly the higher-performing chip in every measured metric.

The Verdict

The data directs a clear verdict. The Intel Core Ultra 7 265KF outperforms the AMD Ryzen AI 9 HX 375 in every recorded benchmark, with margins ranging from 15.1% in PassMark integer math to 74.9% in PassMark prime numbers. The Intel part also has a higher average benchmark score (71910 versus 46030) and a higher percentile ranking (94th versus 89th). For any workload captured in the database, the Intel chip is the faster choice.

The AMD Ryzen AI 9 HX 375 is not without its place, but that place is defined by its mobile platform characteristics. It runs at 28 W TDP, fits Socket FP8, and includes Radeon 890M integrated graphics, making it suitable for compact or power-constrained systems where a discrete GPU is not available. The Intel Core Ultra 7 265KF demands a desktop platform, a separate graphics card, and 125 W of power budget, but it rewards that investment with substantial performance advantages across Cinebench, Geekbench, and all PassMark workloads. The benchmark results indicate that the Intel part is the superior processor for raw compute, while the AMD part offers integrated graphics and a mobile form factor that the Intel part cannot match. The recorded data does not provide any scenario where the AMD chip wins a performance test, so the verdict is straightforward: the Intel Core Ultra 7 265KF is the higher-performing CPU in every measured metric.
