Where Each One Wins

The data splits cleanly along workload types. The AMD Ryzen AI Max+ 392 dominates in every multithreaded and compute-heavy PassMark test. Its largest margin comes in integer math, where it scores 152,414 against the Intel's 41,558, a 266.8% difference. Data compression also shows a massive gap: 554,760 for AMD versus 187,050 for Intel, a 196.6% advantage. Extended instructions follow at 186.7% ahead, with random string sorting at 159.7% ahead.

The Intel Core Ultra 7 266V wins only in the single-threaded PassMark tests. Its score of 3,943 edges out the AMD's 3,927 by a narrow 0.4%. This is a marginal victory, not a commanding one, but it does indicate that Intel's single-core design holds a slight edge in lightly threaded workloads.

The AMD processor also wins the remaining tests: data encryption at 101% ahead, physics at 79.5% ahead, floating point math at 74.9% ahead, and prime number finding at 67.5% ahead. The multithread test itself shows a 132.4% advantage for AMD.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Max+ 392 uses the Zen 5 architecture under the Strix Halo codename, built on a 4 nm TSMC process. It features 12 cores and 24 threads, with a base clock of 3.20 GHz and a boost clock of 5.00 GHz. The die size is listed as 2x 70.6 mm².

The Intel Core Ultra 7 266V uses the Lunar Lake architecture, part of the Core Ultra Series 2 family, built on a 3 nm TSMC process. It has 8 cores and 8 threads, meaning no hyperthreading support. Its base clock is 2.20 GHz with the same 5.00 GHz boost clock as the AMD chip.

Cache hierarchies differ substantially. The AMD processor has 80 KB of L1 cache per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The Intel processor has 192 KB of L1 per core, 2.5 MB of L2 per core, and only 12 MB of shared L3. Intel's larger per-core L1 and L2 allocations reflect a different cache strategy, while AMD's massive 64 MB L3 pool supports its higher thread count.

Memory architecture also diverges. AMD uses a quad-channel LPDDR5X interface delivering 256.0 GB/s of bandwidth, while Intel uses a dual-channel LPDDR5X interface delivering 136.5 GB/s. AMD also supports ECC memory; Intel does not. The PCIe implementations differ as well: AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 4 lanes (CPU only).

The integrated graphics differ: AMD pairs the CPU with a Radeon 8060S, while Intel uses the Arc 140V. Both are mobile processors, and both are actively in production.

Specification Differences

The core and thread counts present the most immediate difference. AMD offers 12 cores and 24 threads; Intel offers 8 cores and 8 threads. The base clock differs as well: AMD runs at 3.20 GHz, Intel at 2.20 GHz. Both boost to 5.00 GHz.

Thermal design power shows a major split. The AMD Ryzen AI Max+ 392 has a TDP of 55 watts, while the Intel Core Ultra 7 266V has a TDP of 17 watts. This suggests Intel targets far lower power envelopes, while AMD uses additional power to feed its higher core count and thread count.

The sockets differ: AMD uses the FP11 socket, Intel uses BGA 2833. Process nodes differ: 4 nm for AMD, 3 nm for Intel, both from TSMC. Memory channels differ: quad-channel for AMD, dual-channel for Intel. Memory bandwidth follows: 256.0 GB/s versus 136.5 GB/s. ECC support exists only on the AMD side.

Cache configurations differ in both size and distribution. AMD allocates 80 KB L1 and 1 MB L2 per core with 64 MB shared L3. Intel allocates 192 KB L1 and 2.5 MB L2 per core with 12 MB shared L3. The PCIe generation and lane counts also differ: Gen 4 with 16 lanes for AMD, Gen 5 with 4 lanes for Intel.

Release dates separate the two by over a year. The Intel Core Ultra 7 266V launched on 2024-09-23, while the AMD Ryzen AI Max+ 392 launched on 2026-01-05. Neither processor has a listed launch MSRP, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen AI Max+ 392 comes in integer math. The AMD scores 152,414 against Intel's 41,558, a 266.8% delta. This test stresses basic arithmetic operations, and the difference reflects both the higher core count and the thread advantage.

Data compression shows a 196.6% lead for AMD, with scores of 554,760 versus 187,050. This workload benefits from parallel processing, where AMD's 24 threads overwhelm Intel's 8. Extended instructions follow with a 186.7% advantage: 45,666 for AMD versus 15,928 for Intel.

Random string sorting gives AMD a 159.7% edge, scoring 59,487 against 22,905. The multithread test shows a 132.4% advantage, with AMD at 45,231 and Intel at 19,461. Data encryption delivers a 101% lead for AMD: 27,784 versus 13,822.

Physics testing shows a 79.5% advantage for AMD, scoring 2,887 against Intel's 1,608. Floating point math gives AMD a 74.9% lead: 99,548 versus 56,923. Prime number finding shows the smallest AMD win at 67.5%, with scores of 320 versus 191.

The only Intel victories come in the single-thread tests. The Intel Core Ultra 7 266V scores 3,943 against AMD's 3,927, a 0.4% delta. Both the passmark_single_thread and passmark_singlethread entries record the same result. This shows Intel's single-core performance is slightly better, but the margin is small enough that real-world differences would be negligible.

Looking at the broader context, the AMD processor's average benchmark score of 90,541 puts it in the 96th percentile of all CPUs. Its nearest rivals include the Intel Xeon 654 at 90,717 (0.2% behind) and the AMD Ryzen 9 9955HX at 91,199 (0.7% behind). The Intel Core Ultra 7 266V's average score of 23,297 places it in the 76th percentile, with its nearest rival being the AMD Ryzen 7 5800H at 23,277 (0.1% behind).

The Verdict

The benchmark data tells a clear story. The AMD Ryzen AI Max+ 392 dominates in multithreaded performance, memory bandwidth, and nearly every compute workload tested. Its 24 threads and 64 MB of L3 cache deliver advantages ranging from 67.5% to 266.8% across the PassMark suite. The processor sits in the 96th percentile overall, adjacent to server-class Xeon parts.

The Intel Core Ultra 7 266V wins only in single-threaded performance, and even there by just 0.4%. Its 17 watt TDP and 3 nm process indicate a focus on efficiency rather than raw throughput. Its 76th percentile placement and average score of 23,297 place it alongside older desktop parts like the Intel Core i9-11900F.

For workloads that scale with threads, memory bandwidth, or cache capacity, the AMD Ryzen AI Max+ 392 is the clear choice. The data shows consistent, often overwhelming advantages across compression, encryption, math, and physics tests. Its quad-channel memory interface and 256.0 GB/s bandwidth support these results.

For lightly threaded tasks where single-core speed matters most, the Intel Core Ultra 7 266V holds a slight edge. Its lower TDP also makes it suitable for power-constrained designs. But the magnitude of AMD's wins in nearly every other category outweighs Intel's marginal single-thread advantage. The recorded data supports selecting the AMD Ryzen AI Max+ 392 for any workload that can use more than a few threads.
