Where Each One Wins

The benchmark data splits the two processors into distinct usage profiles. The AMD Ryzen AI Max+ 392 wins 7 of the 11 head-to-head tests, and those wins are concentrated in heavy multi-threaded workloads. The Intel Core Ultra X7 368H wins 4 tests, but its wins are mostly in single-threaded and specific math tasks.

For data compression, the AMD part is the clear choice. Its score of 554760 is 77.3% above the Intel part's 312927. Similarly, extended instructions favor AMD by 77.9%, with scores of 45666 versus 25669. Integer math also goes strongly to AMD, 152414 versus 88083, a 73% margin. Random string sorting is another AMD win, 59487 versus 38093, a 56.2% lead. The multithread score follows the same pattern, with AMD at 45231 and Intel at 32956, a 37.2% difference.

The Intel Core Ultra X7 368H takes the single-thread test with 4005 versus 3927, a 1.9% edge. It also wins floating point math, 105681 versus 99548, a 5.8% margin. The find prime numbers test is nearly a tie, with Intel at 321 and AMD at 320, a 0.3% difference. These wins suggest Intel has a slight advantage in lightly threaded workloads and certain math operations.

Data encryption is a closer contest. AMD wins with 27784 versus 25228, a 10.1% margin. Physics is nearly even, with AMD at 2887 and Intel at 2857, a 1.1% difference. The overall pattern shows AMD dominating throughput-oriented tasks while Intel holds a smaller edge in latency-sensitive or single-threaded work.

Architecture Differences

The AMD Ryzen AI Max+ 392 uses the Zen 5 architecture on the Strix Halo codename. It is built on a 4 nm process at TSMC. The Intel Core Ultra X7 368H uses the Panther Lake architecture, built on a 3 nm process at Intel. These are different design philosophies: AMD uses a chiplet approach with a die size of 2x 70.6 mm², while Intel's die size is not recorded in the database.

Cache organization differs substantially. AMD provides 80 KB of L1 per core and 1 MB of L2 per core, with 64 MB of shared L3. Intel provides 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3. The Intel part has more per-core cache, but AMD has far more total L3.

Memory support is LPDDR5X for both, but the bus configurations differ. AMD uses a quad-channel interface with 256.0 GB/s bandwidth and supports ECC memory. Intel uses a dual-channel interface with 153.6 GB/s bandwidth and does not support ECC. PCIe also differs: AMD offers Gen 4 with 16 lanes CPU-only, while Intel offers Gen 5 with 4 lanes CPU-only.

The integrated graphics differ as well. AMD pairs the processor with Radeon 8060S graphics, while Intel uses Arc B390. Both are mobile processors with active production status, released one day apart in January 2026. The AMD part has part number 100-000001979, and the Intel part has part number SA4R7Q9EJ. Neither has a multiplier unlocked.

Specification Differences

The core and thread counts differ as noted: AMD has 12 cores and 24 threads, Intel has 16 cores and 16 threads. Base clocks differ significantly, with AMD at 3.20 and Intel at 2.00. Boost clocks are identical at 5.00 for both.

TDP is a major differentiator. AMD is rated at 55, Intel at 25. This means the Intel part is designed for a lower power envelope, which typically suits thinner systems, while AMD targets higher-performance mobile designs.

Socket types differ: AMD uses AMD Socket FP11, Intel uses Intel BGA 2540. The process nodes are different, 4 nm for AMD and 3 nm for Intel. Foundries also differ, with TSMC for AMD and Intel for Intel.

Cache specifications show the L1 and L2 per core differences. AMD has 80 KB L1 and 1 MB L2 per core. Intel has 192 KB L1 and 2.5 MB L2 per core. L3 is 64 MB shared for AMD versus 18 MB shared for Intel. ECC support is present on AMD only.

Memory bandwidth is a clear separation: 256.0 GB/s for AMD versus 153.6 GB/s for Intel. The memory bus is quad-channel on AMD and dual-channel on Intel. PCIe generations and lane counts also differ: Gen 4 with 16 lanes on AMD, Gen 5 with 4 lanes on Intel.

The integrated graphics names are Radeon 8060S for AMD and Arc B390 for Intel. Both parts are marked as mobile market segment and are in active production.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen AI Max+ 392 is in data compression. AMD scores 554760 against Intel's 312927, a 77.3% advantage. This is a workload that benefits from high memory bandwidth and large caches, both of which AMD has. The extended instructions test shows a similar margin, with AMD at 45666 and Intel at 25669, a 77.9% difference. Integer math also goes heavily to AMD, 152414 versus 88083, a 73% lead.

Random string sorting is another strong AMD result, 59487 versus 38093, a 56.2% margin. The multithread score favors AMD by 37.2%, with 45231 against 32956. These four tests are all throughput-oriented, and AMD's advantage is consistent across them.

The Intel Core Ultra X7 368H's biggest win is in floating point math. Intel scores 105681, which is 5.8% higher than AMD's 99548. The single-thread test goes to Intel by 1.9%, 4005 versus 3927. The find prime numbers test is essentially a tie, with Intel at 321 and AMD at 320, a 0.3% difference. Data encryption is an AMD win at 27784 versus 25228, a 10.1% margin, but this is a smaller gap than the other AMD wins. Physics is very close, AMD at 2887 and Intel at 2857, a 1.1% difference.

The overall win count is 7 for AMD and 4 for Intel. The average benchmark score reflects this: AMD has an average of 90541, while Intel has an average of 40518. AMD's percentile versus all CPUs is 96, compared to Intel's 87.

The nearest rivals in the database provide context. For AMD, the closest rival is the Intel Xeon 654 with an average score of 90717, a delta of -0.2%. The AMD Ryzen 9 9955HX is next at 91199, a -0.7% delta. For Intel, the closest rival is the Intel Core 7 253PE at 40557, a -0.1% delta, followed by the Intel Core 5 223PE at 40585, a -0.2% delta.

The Verdict

The data supports a clear split in use cases. The AMD Ryzen AI Max+ 392 is the stronger choice for multi-threaded and bandwidth-heavy workloads. Its wins in data compression, extended instructions, integer math, and random string sorting are decisive, with margins between 56% and 78%. The 64 MB L3 cache and 256.0 GB/s memory bandwidth are the likely contributors to these results. The multithread score, 45231 versus 32956, confirms that AMD handles parallel workloads substantially better.

The Intel Core Ultra X7 368H is the better option for single-threaded and floating-point tasks. Its single-thread score of 4005 beats AMD by 1.9%, and its floating point score of 105681 beats AMD by 5.8%. The lower TDP of 25 also indicates it is suited for systems with tighter power budgets. The find prime numbers test is a statistical tie, so Intel does not have a meaningful edge there.

For a buyer choosing between these two, the decision hinges on the primary workload. If the system runs compression, encryption, sorting, or heavily threaded compute, the AMD Ryzen AI Max+ 392 delivers far higher throughput. If the workload is lightly threaded or relies on floating point math, the Intel Core Ultra X7 368H offers a small but measurable advantage. The average benchmark score, 90541 for AMD versus 40518 for Intel, is not directly comparable across all tests due to the different test sets, but the head-to-head results are decisive in AMD's favor for most tasks. The percentile ranking, 96 versus 87, also places AMD higher in the overall CPU hierarchy.
