AMD Ryzen AI Max+ PRO 395 vs Intel Core Ultra 7 366H Comparison

# AMD Ryzen AI Max+ PRO 395 vs Intel Core Ultra 7 366H

The AMD Ryzen AI Max+ PRO 395 and Intel Core Ultra 7 366H are both 16-core mobile processors, yet they target fundamentally different workloads. The recorded data shows a clear split: AMD wins 12 of 15 head-to-head benchmarks, while Intel secures 3 wins. The AMD part posts an average benchmark score of 80762, placing it in the 95th percentile of all CPUs, while the Intel chip averages 41263, sitting in the 87th percentile. The nearest rivals to AMD include the Intel Xeon 638 at 80723 (0% delta) and the AMD Ryzen 9 8940HX at 81103 (-0.4% delta). For Intel, the closest competitor is the Intel Core Ultra 7 356H at 41215 (0.1% delta). These contextual numbers frame a comparison where AMD delivers roughly double the aggregate throughput, but Intel counters with notable single-thread efficiency in specific legacy tests.

Where Each One Wins

The AMD Ryzen AI Max+ PRO 395 dominates throughput-oriented workloads. Multi-threaded rendering, data compression, encryption, and integer math all fall firmly in AMD's favor. The Cinebench R23 multicore score of 35061 versus Intel's 28477 represents a 23.1% advantage, while the PassMark integer math result of 190720 versus 83695 shows a 127.9% lead. Data compression delivers a 95.3% gap (639356 versus 327455), and extended instructions show a 93.6% difference (52067 versus 26901). The AMD chip also wins multithread (51502 versus 33429, 54.1%), random string sorting (70150 versus 39814, 76.2%), data encryption (32840 versus 25845, 27.1%), floating-point math (120533 versus 103615, 16.3%), and physics (3189 versus 2880, 10.7%). Even in single-thread PassMark, AMD edges ahead, scoring 4078 versus 4043, a narrow 0.9% margin.

The Intel Core Ultra 7 366H wins three specific tests, all in the Cinebench R15 or R23 single-core suite. The R15 single-core result of 405 versus 306 gives Intel a 24.4% advantage, and the R23 single-core score of 4020 versus 2012.5 shows a 49.9% lead. Intel also wins the PassMark find prime numbers test, scoring 326 versus 284, a 12.9% margin. These wins indicate that Intel holds a genuine advantage in lightly threaded, latency-sensitive workloads, particularly those that rely on per-core performance in older benchmark versions.

Architecture Differences

The two processors use entirely different design philosophies. AMD's Ryzen AI Max+ PRO 395 uses the Zen 5 architecture on a 4 nm TSMC process, codenamed Strix Halo. It features 16 cores and 32 threads, meaning each core supports two threads via SMT. The base clock is 3.00 GHz with a boost clock of 5.10 GHz, and the TDP is rated at 55 W. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a large 64 MB shared L3 cache. Memory support is LPDDR5X over a quad-channel bus, yielding 256.0 GB/s of bandwidth, and ECC memory is supported. The integrated graphics is the Radeon 8060S, and the part uses PCIe Gen 4 with 16 CPU lanes. It mounts on AMD Socket FP11.

Intel's Core Ultra 7 366H uses the Panther Lake architecture on a 3 nm Intel process, part of the Core Ultra Series 3 (Panther Lake-H generation). It also has 16 cores but only 16 threads, indicating no hyperthreading. The base clock is 2.00 GHz with a boost of 4.80 GHz, and the TDP is 25 W. Cache sizes differ substantially: 192 KB of L1 per core, 2.5 MB of L2 per core, and just 18 MB of shared L3. Memory support includes both DDR5 and LPDDR5X over a dual-channel bus, delivering 115.2 GB/s, less than half of AMD's bandwidth. ECC is not supported. The integrated graphics is Intel Xe3 Graphics, and the CPU uses PCIe Gen 5 with 12 lanes. The socket is Intel BGA 2540.

These differences explain the benchmark outcomes. AMD's 32 threads and 64 MB L3 cache directly benefit multi-threaded and data-heavy tasks. Intel's smaller 18 MB L3 and 16 threads limit scalability, but the higher per-core L1 and L2 caches, combined with a 3 nm process, contribute to its strong single-core results in R15 and R23.

Head-to-Head Benchmarks

The largest AMD win appears in integer math. The score of 190720 versus 83695 yields a 127.9% delta, the widest gap in the dataset. This result indicates that AMD's Zen 5 cores, when operating with 32 threads, process integer operations at more than twice the rate of Intel's 16-thread design. Data compression shows a similar pattern, with AMD scoring 639356 versus 327455, a 95.3% advantage. Extended instructions follow at 93.6% (52067 versus 26901), reinforcing AMD's dominance in SIMD and specialized instruction workloads.

The PassMark multithread test gives AMD 51502 against Intel's 33429, a 54.1% lead. Random string sorting shows 70150 versus 39814, a 76.2% gap. Cinebench R15 multicore delivers the second-largest percentage difference at 82.8%, with AMD scoring 5247 against Intel's 2870. The R23 multicore gap is smaller at 23.1%, suggesting that Intel's newer architecture scales better in the longer-duration R23 test, though it still trails by a substantial margin.

Intel's wins are concentrated in single-core Cinebench. The R23 single-core result of 4020 versus 2012.5 represents a 49.9% advantage, meaning Intel's single core is nearly twice as fast as AMD's in that specific test. The R15 single-core score of 405 versus 306 gives Intel a 24.4% edge. The find prime numbers test shows a 12.9% Intel advantage (326 versus 284), a workload that likely favors Intel's higher per-core clock and lower thread overhead. In the PassMark single-thread tests, AMD narrowly wins by 0.9% (4078 versus 4043), which indicates that outside the Cinebench suite, the two chips have comparable single-thread performance.

FAQ

Q: Which processor has better multi-threaded performance?

A: The AMD Ryzen AI Max+ PRO 395. It wins every multi-threaded benchmark in the comparison, including Cinebench R23 multicore (35061 versus 28477, a 23.1% lead) and PassMark multithread (51502 versus 33429, a 54.1% lead).

Q: Does the Intel Core Ultra 7 366H win any benchmarks?

A: Yes, it wins three tests: Cinebench R15 single-core (405 versus 306, 24.4% ahead), Cinebench R23 single-core (4020 versus 2012.5, 49.9% ahead), and PassMark find prime numbers (326 versus 284, 12.9% ahead).

Q: How do the two chips compare in memory bandwidth?

A: The AMD part uses quad-channel LPDDR5X with 256.0 GB/s of bandwidth, while the Intel part uses dual-channel DDR5/LPDDR5X with 115.2 GB/s. AMD's bandwidth is more than double Intel's.

Q: What is the thread count difference?

A: AMD has 16 cores and 32 threads, while Intel has 16 cores and 16 threads. AMD's SMT implementation doubles the thread count, which contributes to its large multi-threaded leads.

Q: Which processor has a higher boost clock?

A: AMD's boost clock is 5.10 GHz, while Intel's is 4.80 GHz. However, Intel's single-core Cinebench scores are higher, indicating that clock speed alone does not determine per-core performance.

Q: How do the integrated graphics compare?

A: The AMD part uses the Radeon 8060S, while the Intel part uses Intel Xe3 Graphics. The database does not include direct graphics benchmarks, so a performance comparison cannot be made from the recorded data.
