Where Each One Wins

The AMD Ryzen AI 7 450G claims four head-to-head victories across the recorded PassMark suite. Its largest win comes in data compression, where it scores 402831 against the Intel chip's 334711, a 20.4% advantage. The AMD part also leads in integer math with a score of 99732 versus 85479, a 16.7% margin. Extended instructions favor AMD by 5.3%, with scores of 28223 and 26805 respectively. Random string sorting also goes to AMD, 42663 to 40742, a 4.7% edge.

The Intel Core Ultra 7 265H wins seven of the eleven recorded head-to-head tests, and several of its victories are substantial. The most dramatic gap appears in the find prime numbers test, where Intel scores 335 against AMD's 87, a 74% advantage. Floating point math heavily favors Intel as well: 109123 versus 63683, a 41.6% margin. Physics simulation shows a similar pattern, with Intel at 2497 and AMD at 1440, a 42.3% difference.

The Intel chip also takes the multithread test, scoring 34027 against AMD's 30422, a 10.6% margin. Data encryption goes to Intel by 27.2%, with scores of 26005 and 18937. The single-thread test is essentially a tie, but Intel edges ahead with 4334 versus 4309, a 0.6% difference.

This split suggests AMD's architecture excels at compression, integer workloads, and string manipulation, while Intel's design dominates floating point, prime number generation, physics, and encryption. The database shows that the Intel part's core count advantage translates directly into wins for parallel floating-point workloads.

Architecture Differences

The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core Ultra 7 265H uses the Arrow Lake-H codename, part of the Core Ultra Series 2, and is built on a 3 nm process, also at TSMC. Intel does not list a die size in the database.

Cache organization differs substantially. The AMD chip provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. The Intel chip provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The Intel part therefore has significantly more cache at every level, which helps explain its floating point and physics performance.

Memory bandwidth also differs. The AMD processor records 89.6 GB/s, while the Intel processor records 102.4 GB/s. Both use dual-channel memory buses and support DDR5 and LPDDR5X. The Intel chip's higher bandwidth aligns with its stronger encryption and floating point results.

The AMD part uses PCIe Gen 4 with 12 lanes from the CPU, while the Intel part uses PCIe Gen 5 with 8 lanes from the CPU. The integrated graphics differ as well: AMD pairs with Radeon 860M, while Intel pairs with Arc Graphics 140T.

The AMD processor has an unlocked multiplier, whereas the Intel processor does not. The AMD chip uses an AMD Socket AM5, while the Intel chip uses Intel BGA 2049. The market segments differ: AMD targets desktop, Intel targets mobile.

Specification Differences

The two processors diverge on nearly every core specification. The AMD Ryzen AI 7 450G has 8 cores and 16 threads, while the Intel Core Ultra 7 265H has 16 cores and 16 threads. Base clocks differ: 2.00 GHz for AMD versus 2.20 GHz for Intel. Boost clocks also differ: 5.10 GHz for AMD versus 5.30 GHz for Intel.

TDP is the largest specification gap. The AMD part draws 65 watts, while the Intel part draws 28 watts. This reflects their different target platforms: desktop versus mobile. The Intel chip's lower TDP comes despite having twice the core count, which points to the efficiency of its 3 nm process.

The cache hierarchy differs at every level, as noted above. The Intel chip offers more than double the L1 per core, triple the L2 per core, and triple the L3 total. Memory bandwidth favors Intel by 12.8 GB/s.

The process node favors Intel at 3 nm versus AMD's 4 nm. The AMD chip has a documented die size of 195 mm²; Intel does not report a die size. The AMD part carries part number 100-000001917, while the Intel part carries SRQAQ.

Release dates differ. The Intel Core Ultra 7 265H was released on 2025-01-12, while the AMD Ryzen AI 7 450G was released on 2026-02-28. Both are marked as active in production.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen AI 7 450G comes in data compression, where its score of 402831 beats the Intel Core Ultra 7 265H's 334711 by 20.4%. This is a workload that benefits from the AMD chip's integer throughput and memory access patterns. The integer math test reinforces this strength: AMD scores 99732 against Intel's 85479, a 16.7% margin.

The AMD chip also wins extended instructions by 5.3%, scoring 28223 versus 26805. Random string sorting goes to AMD by 4.7%, with scores of 42663 and 40742. These wins are consistent with an architecture that handles data manipulation and algorithmic workloads efficiently.

The Intel Core Ultra 7 265H dominates the floating point domain. In floating point math, Intel scores 109123 against AMD's 63683, a 41.6% advantage. The physics test shows a similar gap: 2497 versus 1440, a 42.3% difference. These are the largest percentage wins for Intel in the recorded data.

Intel's find prime numbers result is the most lopsided of all: 335 versus 87, a 74% gap. This test likely benefits from Intel's higher core count and larger cache. Data encryption goes to Intel by 27.2%, with scores of 26005 and 18937.

The multithread test favors Intel by 10.6%, scoring 34027 against AMD's 30422. This is notable because the AMD chip has a much higher average benchmark score overall, yet the Intel part wins the aggregate multithread PassMark score. The single-thread tests are nearly identical, with Intel ahead by just 0.6% in both recorded instances.

The database shows a clear trade-off: AMD wins integer-heavy and compression workloads by double digits, while Intel wins floating point and encryption workloads by even larger margins. The Intel chip's raw core count appears to drive its multithread victory, despite the AMD chip's higher average across all recorded benchmarks.

The Verdict

The recorded data points to two different usage profiles. The AMD Ryzen AI 7 450G delivers its strongest results in data compression, integer math, extended instructions, and random string sorting. Its 93rd percentile ranking and average benchmark score of 63331 place it among the top processors in the database. The Intel Core Ultra 7 265H, sitting at the 88th percentile with an average score of 41621, wins on floating point math, physics, encryption, prime number generation, and the multithread test.

The Intel chip's 16 physical cores versus the AMD chip's 8 cores with simultaneous multithreading is the central architectural distinction. That core advantage shows up in the multithread score, where Intel leads by 10.6%. The AMD chip compensates with higher per-core efficiency in specific integer workloads, as demonstrated by its 20.4% compression win and 16.7% integer math win.

The TDP difference is substantial: 28 watts for Intel versus 65 watts for AMD. This makes the Intel chip suitable for mobile platforms, while the AMD chip targets desktop systems. The Intel chip's 3 nm process and larger cache hierarchy, 24 MB of L3 versus 8 MB, support its floating point dominance.

For workloads involving encryption, physics simulation, floating point calculations, or prime number generation, the Intel Core Ultra 7 265H is the stronger choice based on the benchmark data. For compression, integer math, extended instructions, and string sorting, the AMD Ryzen AI 7 450G shows clear advantages.

The single-thread performance is effectively identical, with less than 1% separating the two processors. Buyers choosing between them should weigh the Intel chip's multithread and floating point wins against the AMD chip's higher overall percentile and integer workload superiority. The data does not indicate a universal winner; it indicates a workload-dependent split.
