Architecture Differences

The AMD Ryzen AI 7 450 is built on the Zen 5 architecture, codenamed Gorgon Point, and belongs to the Ryzen AI 400 generation that mixes Zen 5 and Zen 5c cores. It is fabricated on TSMC's 4 nm process with a die size of 195 mm². The Intel Core Ultra 9 386H uses the Panther Lake architecture, part of the Core Ultra Series 3 generation, produced on Intel's 3 nm node. This process difference gives Intel a smaller transistor geometry, although the database does not record transistor counts for either chip.

Core organization diverges sharply. AMD packs 8 cores with 16 threads, while Intel provides 16 cores with 16 threads, meaning AMD relies on simultaneous multithreading to double its thread count, whereas Intel's 16 cores each handle a single thread. Cache hierarchies also differ: AMD allocates 80 KB of L1 and 1 MB of L2 per core, with 8 MB of shared L3. Intel allocates 192 KB of L1 and 2.5 MB of L2 per core, with 18 MB of shared L3. That leaves Intel with more than double the L3 capacity and substantially larger per-core L1 and L2 allocations.

Memory bandwidth favors Intel at 115.2 GB/s versus AMD's 89.6 GB/s, although both support DDR5 and LPDDR5X over dual channels. ECC memory is supported only by the AMD part. PCIe connectivity differs as well: AMD offers Gen 4 with 16 CPU lanes, while Intel offers Gen 5 with 12 CPU lanes. Integrated graphics also differ, with AMD using Radeon 860M and Intel using Xe3 Graphics. Both processors share the same release date of 2026-01-04, are active in production, target the mobile segment, and have locked multipliers.

The Verdict

The recorded data indicates that the Intel Core Ultra 9 386H is the stronger overall performer. Its average benchmark score of 43210 places it 9.4% above the AMD Ryzen AI 7 450's 39485, and it wins 14 of the 15 head-to-head benchmark comparisons. The Intel chip's nearest rivals include the AMD Ryzen AI Max PRO 385 at 43326 (-0.3%), the AMD Ryzen AI 9 465 at 43431 (-0.5%), and the Intel Core i9-12900 at 42906 (+0.7%), positioning it in the upper tier of mobile processors.

The AMD Ryzen AI 7 450 still holds a narrow advantage in one specific workload: PassMark integer math, where it scores 88531 against Intel's 87284, a 1.4% lead. For buyers prioritizing ECC memory support, the AMD chip is the only option, as the Intel part lacks it. AMD also offers the higher boost clock at 5.10 GHz versus 4.90 GHz, and its 4 nm TSMC process may appeal to those tracking fabrication differences.

The verdict from the database is clear: the Intel Core Ultra 9 386H delivers superior multi-threaded, single-threaded, and specialized workload performance across nearly every recorded test. The AMD Ryzen AI 7 450 remains relevant only for ECC-capable systems and integer math tasks. For general mobile computing, the data favors Intel by a wide margin.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen AI 7 450 has 8 cores and 16 threads, while the Intel Core Ultra 9 386H has 16 cores and 16 threads. Base clocks are close, with AMD at 2.00 GHz and Intel at 2.10 GHz, but boost clocks reverse the order: AMD reaches 5.10 GHz while Intel tops out at 4.90 GHz. TDP ratings differ modestly, with AMD at 28 and Intel at 25.

Cache configurations are entirely different. AMD uses 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. Intel uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. Memory bandwidth favors Intel at 115.2 GB/s versus 89.6 GB/s. ECC support is present only on AMD. PCIe generation and lane counts differ, with AMD offering Gen 4 across 16 lanes and Intel offering Gen 5 across 12 lanes. Integrated graphics are Radeon 860M for AMD and Intel Xe3 Graphics for Intel.

Process technology differs by foundry and node: AMD uses TSMC's 4 nm process with a 195 mm² die, while Intel uses its own 3 nm process with no die size recorded. Sockets are incompatible, with AMD on AMD Socket FP8 and Intel on Intel BGA 2540. The architecture names differ completely, Zen 5 for AMD and Panther Lake for Intel, as do their codenames, Gorgon Point versus Panther Lake. Manufacturing is split between TSMC and Intel. The AMD part number is 100-000001868, and the Intel part number is SA4R5Q9EH. Both are active in production, unlocked multipliers are not available on either, and neither has a recorded launch MSRP in the database.

Head-to-Head Benchmarks

The Intel Core Ultra 9 386H dominates the head-to-head results, winning 14 of 15 comparisons. The largest Intel victories come in PassMark find prime numbers, where Intel scores 341 against AMD's 89, a 73.9% advantage. PassMark floating point math shows Intel at 108527 versus 54447, a 49.8% lead. PassMark physics follows with Intel at 3028 and AMD at 1578, a 47.9% gap. PassMark data encryption gives Intel 27150 against AMD's 16247, a 40.2% margin. PassMark multithread shows Intel at 35399 versus 26350, a 25.6% lead, and PassMark extended instructions favors Intel at 29138 versus 22400, a 23.1% difference.

Cinebench results follow the same pattern. In Cinebench R15 single-core, Intel scores 303.5 against AMD's 215, a 29.2% advantage. Cinebench R15 multi-core gives Intel 3223 versus 2713, a 15.8% lead. Cinebench R23 multi-core shows Intel at 20547 and AMD at 18316, a 10.9% margin. The narrowest Intel win in Cinebench is R23 single-core, where Intel scores 2071.5 and AMD scores 2038, a 1.6% difference. PassMark random string sorting favors Intel at 42135 versus 35648, a 15.4% lead, and PassMark data compression gives Intel 352365 against AMD's 315906, a 10.3% margin. PassMark single-thread shows Intel at 4218 versus 3901, a 7.5% lead, with the same result recorded under the singlethread test name.

The AMD Ryzen AI 7 450 claims only one win: PassMark integer math at 88531 versus 87284, a 1.4% advantage. That single victory does little to offset the overall trend, as Intel's average score of 43210 exceeds AMD's 39485 by roughly 9.4%. The closest Intel margin in the entire comparison is the 1.6% edge in Cinebench R23 single-core, suggesting that AMD's Zen 5 architecture closes the gap in lightly threaded rendering tasks. The data shows a processor that is competitive in a single integer workload but consistently behind in floating point, encryption, physics, compression, and both single- and multi-core rendering tests.
