Q: Do both processors support ECC memory?

A: No. The AMD Ryzen AI Max PRO 385 supports ECC memory, while the Intel Core Ultra 7 366H does not list ECC support. This makes the AMD part more suitable for error-sensitive workloads.

Q: What are the process node differences between the two chips?

A: The AMD Ryzen AI Max PRO 385 is built on a 4 nm process by TSMC. The Intel Core Ultra 7 366H uses a 3 nm process by Intel. The Intel part uses a smaller process node, which contributes to its lower 25 W TDP compared to AMD's 55 W TDP.

Architecture Differences

The AMD Ryzen AI Max PRO 385 and Intel Core Ultra 7 366H take fundamentally different design approaches. AMD's chip uses the Zen 5 architecture under the Strix Halo codename, while Intel's part relies on the Panther Lake architecture. The AMD processor is a mobile part with 8 cores and 16 threads, whereas the Intel processor packs 16 cores and 16 threads, meaning Intel's chip has no simultaneous multithreading.

Cache hierarchies diverge sharply. AMD allocates 80 KB of L1 cache per core and 1 MB of L2 per core, with 32 MB of shared L3. Intel provides 192 KB of L1 per core and 2.5 MB of L2 per core, but only 18 MB of shared L3. Intel's larger per-core L1 and L2 caches help latency-sensitive single-threaded work, while AMD's larger L3 pool benefits data-heavy multi-threaded tasks.

Memory support differs as well. AMD uses LPDDR5X exclusively with a quad-channel bus and 256.0 GB/s bandwidth. Intel supports both DDR5 and LPDDR5X across a dual-channel bus with 115.2 GB/s bandwidth. AMD's bandwidth advantage is substantial, but Intel's flexibility with DDR5 allows for more varied system designs.

The integrated graphics also differ. AMD pairs its CPU with a Radeon 8050S, while Intel uses Intel Xe3 Graphics. The PCIe implementation shows another split: AMD offers Gen 4 with 16 lanes, while Intel provides Gen 5 with 12 lanes. Intel's newer PCIe generation provides higher per-lane bandwidth, though AMD has more total lanes. Both chips are mobile-segment parts with active production status, but their release dates differ: AMD launched on 2025-01-05, Intel on 2026-01-04.

Head-to-Head Benchmarks

The Cinebench suite shows near-identical performance between the two processors. In Cinebench R23 multi-core, Intel scores 28477 versus AMD's 28424, a delta of only 0.2 percent. Single-core results follow the same pattern: Intel leads 4020 to 4012 in R23, again by 0.2 percent. The R15 and R20 variants mirror this, with Intel winning every Cinebench test by 0.2 percent or less. These differences are within measurement noise, indicating essentially equal CPU rendering capability.

PassMark tests reveal a more polarized picture. AMD dominates data compression with a score of 379448 against Intel's 327455, a 15.9 percent advantage. AMD also wins extended instructions by 16.9 percent (31442 versus 26901) and integer math by 25.5 percent (105056 versus 83695). Random string sorting goes to AMD by a slim 2.4 percent margin (40784 versus 39814).

Intel's PassMark wins are equally decisive. The largest gap comes in find prime numbers, where Intel scores 326 versus AMD's 157, a 51.8 percent advantage. Floating point math favors Intel by 32.8 percent (103615 versus 69580). Physics tests show Intel ahead by 40.6 percent (2880 versus 1711). Data encryption goes to Intel by 26.6 percent (25845 versus 18978). Intel also wins the multithread test by 4.1 percent (33429 versus 32075) and the single-thread test by 1.2 percent (4043 versus 3995).

The overall win tally stands at 13 for Intel and 4 for AMD. The average benchmark scores reflect this distribution: AMD at 43326 and Intel at 41263, a 5.0 percent gap. Intel's wins in physics and prime number calculation suggest strengths in specific computational patterns, while AMD's integer and compression wins indicate efficiency in data manipulation workloads.

The Verdict

The data indicates a clear split in workload suitability. The Intel Core Ultra 7 366H delivers more consistent wins across a broader range of tests, particularly in physics simulation, floating point math, and prime number generation. Its 13 head-to-head wins include every Cinebench test and seven PassMark tests, making it the stronger all-rounder in the database's measurements. The Intel part also does this with a 25 W TDP, less than half of AMD's 55 W TDP, which points to superior energy efficiency for sustained mobile workloads.

The AMD Ryzen AI Max PRO 385 counters with decisive wins in integer math, data compression, and extended instructions. These are workloads tied to data processing and general computation rather than floating point or physics simulation. AMD's quad-channel memory with 256.0 GB/s bandwidth provides a structural advantage for memory-intensive tasks, and its ECC support adds reliability for professional use.

For users prioritizing physics, encryption, or floating point performance, the Intel Core Ultra 7 366H is the clear choice based on the recorded data. For users focused on integer-heavy workloads, data compression, or ECC requirements, the AMD Ryzen AI Max PRO 385 delivers superior results. The two chips are nearly tied in Cinebench rendering, so content creation performance should be considered equivalent.

AMD runs higher clocks (5.00 GHz boost versus 4.80 GHz) but consumes more than double the power (55 W versus 25 W). Intel compensates with more than double the core count (16 versus 8) and a smaller process node (3 nm versus 4 nm). The socket types are incompatible, and neither chip has an unlocked multiplier.

Where Each One Wins

The Intel Core Ultra 7 366H wins in scenarios involving physics simulation, as shown by its 40.6 percent lead in the PassMark physics test. Prime number calculation favors Intel overwhelmingly at 51.8 percent ahead, indicating strength in integer-heavy algorithmic work. Floating point math, encryption, and multithreaded throughput all go to Intel by margins between 4.1 and 32.8 percent. Its lower 25 W TDP makes it suitable for thinner, cooler mobile devices.

The AMD Ryzen AI Max PRO 385 wins in data compression by 15.9 percent and extended instructions by 16.9 percent. Its 25.5 percent lead in integer math points to strong general-purpose computation. Random string sorting goes to AMD by 2.4 percent. The quad-channel memory bus with 256.0 GB/s bandwidth supports memory-bound workloads, and ECC support suits data-integrity-critical applications. AMD's higher 55 W TDP indicates a design that trades power for performance in sustained heavy loads.

The Cinebench results show no meaningful winner: all six tests fall within 0.2 percent of each other. For rendering workloads, the choice between these two chips should be made on other factors like memory bandwidth or power consumption, not raw CPU score.
