AMD Ryzen AI Max+ 392 vs Intel Core i9-14900 Comparison

Head-to-Head Benchmarks

The recorded data splits the eleven head-to-head PassMark tests almost evenly, with the Intel Core i9-14900 taking six wins and the AMD Ryzen AI Max+ 392 taking five. The margins, however, are not symmetrical. The AMD part wins several tests by very large margins, while the Intel part's victories are mostly narrow or moderate.

The largest single win belongs to the AMD Ryzen AI Max+ 392 in the extended instructions test, where it scores 45,666 against Intel's 30,624, a 49.1% advantage. This is followed by the find prime numbers test, where AMD scores 320 versus Intel's 188, a 70.2% lead. These two results indicate that the Zen 5 architecture in the AMD part handles specialized instruction workloads with substantially more efficiency than Raptor Lake.

The AMD part also wins the physics test with 2,887 points against 2,486, a 16.1% margin, and the multithread test with 45,231 against 44,578, a 1.5% edge. In data compression, AMD leads 554,760 to 550,271, a slim 0.8% advantage.

The Intel Core i9-14900 counters with wins in data encryption, floating point math, integer math, random string sorting, and both single-thread tests. The encryption result shows Intel at 33,540 versus AMD's 27,784, a 17.2% margin. Floating point math follows the same pattern: Intel scores 120,262 against AMD's 99,548, also a 17.2% gap. Integer math favors Intel by 12.9%, at 175,010 versus 152,414.

The single-thread result is notable: Intel scores 4,323 against AMD's 3,927, a 9.2% advantage. This reflects the Intel part's higher boost clock of 5.80 GHz against AMD's 5.00 GHz. Random string sorting goes to Intel by a narrow 2.6%, 61,060 versus 59,487.

The overall average benchmark scores tell a different story. The AMD Ryzen AI Max+ 392 has an average benchmark score of 90,541, while the Intel Core i9-14900 averages 58,115. The AMD part sits at the 96th percentile among all CPUs, while Intel sits at the 92nd percentile. The AMD part's nearest rivals include the Intel Xeon 654 at 90,717 (-0.2%), the AMD Ryzen 9 9955HX at 91,199 (-0.7%), the Intel Xeon w7-2575X at 88,172 (+2.7%), and the Intel Xeon 6736P at 87,864 (+3.0%). The Intel Core i9-14900's nearest rivals are the Intel Xeon Platinum 8260M at 58,323 (-0.4%), the AMD Ryzen 7 9850X3D at 58,386 (-0.5%), the Intel Xeon w5-2545 at 58,504 (-0.7%), and the AMD EPYC 9015 at 57,555 (+1.0%).

Where Each One Wins

The AMD Ryzen AI Max+ 392 demonstrates its strongest performance in workloads that stress instruction-level parallelism and specialized computation. The extended instructions result, with a 49.1% lead, points to applications that use SIMD or other advanced instruction sets. The find prime numbers result, a 70.2% lead, indicates an advantage in tight integer loops with heavy branch prediction demands. The physics test, with a 16.1% lead, suggests an edge in simulation workloads that mix floating point and integer operations across many threads. The multithread win, though small at 1.5%, still favors AMD when all threads are active.

The Intel Core i9-14900 wins in areas that rely on raw clock speed and high core counts. The single-thread results, with a 9.2% lead, matter for lightly threaded applications and everyday responsiveness. The encryption win of 17.2% suggests the Intel part has an advantage in cryptographic operations, which often benefit from dedicated instruction paths. Floating point math, also a 17.2% win, indicates Intel handles heavy numerical computation better in this specific PassMark test. Integer math, a 12.9% win, reinforces the pattern. Random string sorting goes to Intel by 2.6%, a small but consistent edge in data manipulation tasks.

The data shows a clear split: AMD wins the tests that involve complex instruction patterns and high per-thread efficiency, while Intel wins the tests that reward higher clock speeds and more traditional throughput. The AMD part's 12 cores and 24 threads deliver strong results across the board, but the Intel part's 24 cores and 32 threads provide a different resource profile. The Intel part's higher boost clock, 5.80 GHz versus 5.00 GHz, explains part of the single-thread gap. The AMD part's larger L3 cache, 64 MB shared versus 36 MB shared, likely contributes to its wins in extended instructions and prime number finding, where working sets can fit in cache.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI Max+ 392 uses the Zen 5 architecture with the Strix Halo codename, built on a 4 nm process at TSMC. The Intel Core i9-14900 uses the Raptor Lake architecture with the Raptor Lake-R codename, built on a 10 nm process at Intel. The manufacturing process difference shows in die size: AMD uses two dies at 70.6 mm² each, while Intel uses a single 257 mm² die.

Core counts differ significantly. The AMD part has 12 cores and 24 threads, while the Intel part has 24 cores and 32 threads. The Intel part does not simply double the AMD part's core count, which indicates a mix of performance and efficiency cores in the Raptor Lake design. The AMD part uses a uniform core layout across its 12 cores.

Cache hierarchies differ in size and organization. Both parts have 80 KB of L1 per core. The AMD part has 1 MB of L2 per core, while the Intel part has 2 MB per core. The L3 cache tells a different story: AMD provides 64 MB shared, while Intel provides 36 MB shared. The AMD part's larger L3 cache gives it an advantage in workloads that repeatedly access a large working set.

Memory support also differs. The AMD part uses LPDDR5X memory with a quad-channel bus and a recorded bandwidth of 256.0 GB/s. The Intel part supports both DDR4 and DDR5 memory with a dual-channel bus, and no bandwidth figure is recorded. The AMD part's quad-channel configuration and higher bandwidth likely contribute to its strong showing in memory-intensive tests like data compression.

Both parts support ECC memory. The AMD part uses PCIe Gen 4 with 16 lanes (CPU only), while the Intel part uses PCIe Gen 5 with 16 lanes (CPU only). The Intel part's newer PCIe standard offers higher potential bandwidth for peripherals, though the CPU-only lane count is identical.

Integrated graphics differ: the AMD part includes a Radeon 8060S, while the Intel part includes UHD Graphics 770. The AMD part targets the mobile market segment with an AMD Socket FP11, while the Intel part targets the desktop segment with an Intel Socket 1700. The AMD part has a base clock of 3.20 GHz and a boost clock of 5.00 GHz, with a TDP of 55 watts. The Intel part has a base clock of 2.00 GHz and a boost clock of 5.80 GHz, with a TDP of 65 watts. The Intel part's higher boost clock aligns with its single-thread wins, while the AMD part's lower TDP reflects its mobile positioning.

The release dates differ by two years. The Intel Core i9-14900 was released on 2024-01-07, while the AMD Ryzen AI Max+ 392 was released on 2026-01-05. Both parts are currently listed as active production. The Intel part has a launch MSRP of $549. The AMD part has no recorded launch MSRP.

The Verdict

The data supports a clear choice based on workload profile. The AMD Ryzen AI Max+ 392 delivers the higher average benchmark score at 90,541, placing it at the 96th percentile, four points above the Intel part's 92nd percentile. The AMD part's average score is roughly 56% higher than the Intel part's 58,115. The AMD part also competes with server-class processors, as its nearest rivals include the Intel Xeon 654, AMD Ryzen 9 9955HX, Intel Xeon w7-2575X, and Intel Xeon 6736P.

The Intel Core i9-14900 remains the better choice for single-thread performance and specific throughput tasks. Its 4,323 single-thread score beats the AMD part's 3,927 by 9.2%. It wins encryption by 17.2%, floating point math by 17.2%, and integer math by 12.9%. These results make it suitable for workloads that depend on high clock speeds and traditional integer or floating point throughput.

The AMD Ryzen AI Max+ 392 is the better choice for specialized instruction workloads and overall multithreaded performance. Its extended instructions lead of 49.1% and prime number lead of 70.2% are the largest margins in the entire comparison. Its multithread win, though only 1.5%, comes despite having half the cores of the Intel part, which indicates higher per-thread efficiency.

For a system that needs broad general-purpose performance with strong single-thread behavior, the Intel part's six head-to-head wins and higher boost clock make it the data-supported pick. For workloads that use advanced instruction sets, physics simulation, or large cache working sets, the AMD part's five wins, including the two largest margins, make it the stronger option.
