AMD Ryzen AI Max+ 388 vs Intel Core 9 273PE Comparison

The Intel Core 9 273PE and AMD Ryzen AI Max+ 388 sit at the same 90th percentile of all CPUs, with average benchmark scores of 49,845 and 49,796, respectively. That 0.1% gap between them is statistically negligible, yet the distribution of wins tells a far more dramatic story. The Intel part takes 12 of the 15 head-to-head tests, while the AMD chip claims only three, but those three are concentrated in areas that reveal fundamentally different design priorities. This is not a case of one chip being simply faster; it is a case of two architectures trading blows across distinct workloads.

Head-to-Head Benchmarks

The most lopsided victories belong to Intel in the Cinebench suite, where the Core 9 273PE's multi-threaded advantage is staggering. In Cinebench R23 multi-core, Intel scores 31,288 against AMD's 18,759, a 66.8% delta that dwarfs every other comparison in this matchup. The single-core gap is even more extreme in percentage terms: Intel's 4,417 in Cinebench R23 single-core is 125.4% ahead of AMD's 1,960. That is not a marginal edge; it is a complete rout. The older Cinebench R15 tests tell a similar story, with Intel leading 49.3% in single-core (445 vs. 298) and 9.8% in multi-core (3,153 vs. 2,872).

PassMark's physics test amplifies the same pattern. Intel posts 3,120 versus AMD's 1,843, a 69.3% advantage that suggests the Core 9 273PE is substantially better at simulated physical interactions, a common proxy for gaming and real-time simulation workloads. Floating-point math also heavily favors Intel: 107,884 vs. 72,722, a 48.4% lead. Integer math is closer but still decisively Intel's, with 139,410 against 109,588, a 27.2% margin. Prime number finding, another single-thread-intense workload, shows Intel ahead by 40% (203 vs. 145).

The AMD Ryzen AI Max+ 388's wins are fewer but instructive. The PassMark single-thread test is its clearest victory: 4,185 vs. 3,650, a 12.8% margin. This is a surprising result given Intel's dominance in Cinebench single-core, and it underscores how different benchmark methodologies can yield contradictory outcomes. AMD also wins extended instructions by a wide 24.7% (32,719 vs. 24,630), indicating superior SIMD or specialized instruction throughput. The third AMD win is in data compression, though it is narrow: 400,887 vs. 405,885 gives Intel a 1.2% edge, meaning AMD actually wins that test by a hair, with the deltaPct listed from Intel's perspective.

Where Each One Wins

The Intel Core 9 273PE is the clear choice for multi-threaded productivity and raw computational throughput. Its 66.8% lead in Cinebench R23 multi-core makes it the pick for rendering, video encoding, and any workload that scales across all 24 threads. The 48.4% advantage in floating-point math further cements this, as scientific computing and financial modeling often rely heavily on FPU performance. The 40% lead in prime number finding and 27.2% lead in integer math also point to general number-crunching superiority. With 12 cores and 24 threads against AMD's 8 cores and 16 threads, the Intel part simply has more parallel resources to throw at demanding tasks, and the benchmarks reflect that.

The AMD Ryzen AI Max+ 388 wins where the workload favors its Zen 5 architecture's efficiency and specialized capabilities. The 12.8% lead in PassMark single-thread suggests that for lightly threaded applications, AMD's 5.00 GHz boost clock and IPC improvements can outpace Intel's 5.70 GHz boost. The 24.7% win in extended instructions is the most interesting, as it indicates AMD's implementation of AVX-512 or similar extensions is significantly faster than Intel's, which is relevant for AI inference, cryptography, and certain scientific workloads. The narrow data compression win (1.2%) hints at better memory-level parallelism, though the margin is too small to be conclusive.

Specification Differences

The two processors diverge on nearly every fundamental specification. The Intel Core 9 273PE operates with a base clock of 2.30 GHz and boosts to 5.70 GHz, while the AMD Ryzen AI Max+ 388 runs at a higher 3.60 GHz base but a lower 5.00 GHz boost. Intel's TDP is 65 watts, exceeding AMD's 55 watts. The socket situation is entirely different: Intel uses Socket 1700 for desktop, while AMD uses Socket FP11 for mobile.

Memory support is a major differentiator. Intel supports DDR4 and DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth. AMD exclusively supports LPDDR5X on a quad-channel bus, delivering 256.0 GB/s, nearly three times the bandwidth. Both support ECC memory. PCIe generations also differ: Intel offers Gen 5 with 16 CPU lanes, while AMD provides Gen 4 with the same lane count.

The integrated graphics are distinct: Intel pairs the CPU with UHD Graphics 730, while AMD includes the Radeon 8060S. The AMD part has a smaller die size at 2x 70.6 mm², while Intel's die size is not listed. The release dates are close but different, with AMD launching on January 5, 2026, and Intel on March 8, 2026. Notably, the Intel part has a launch MSRP of $549, while AMD's launch MSRP is not provided.

Architecture Differences

The architectural divide is stark. Intel's Core 9 273PE is built on a 10 nm process at Intel's own foundry, using the Bartlett Lake codename with a "Core 9 (Bartlett Lake)" generation label. AMD's Ryzen AI Max+ 388 uses TSMC's 4 nm process, with the Zen 5 architecture under the Strix Halo codename. This process node difference—10 nm vs. 4 nm—explains why AMD achieves a lower 55-watt TDP despite a higher base clock, while Intel pushes higher boost frequencies at greater power draw.

Caches differ in structure. Intel allocates 2 MB of L2 per core and 36 MB of shared L3, while AMD provides 1 MB of L2 per core and 32 MB of shared L3. Both share the same 80 KB per-core L1 cache. The memory bus architecture is a fundamental philosophical split: Intel's dual-channel DDR4/DDR5 design prioritizes compatibility and conventional DIMMs, while AMD's quad-channel LPDDR5X configuration prioritizes bandwidth for integrated graphics and data-intensive tasks. AMD's 256.0 GB/s bandwidth is 2.86 times Intel's 89.6 GB/s, which likely contributes to AMD's wins in data compression and extended instructions.

The Intel part is explicitly a desktop segment processor with 12 cores and 24 threads, while AMD's is a mobile segment chip with 8 cores and 16 threads. Despite having fewer physical cores, AMD's Zen 5 architecture at 4 nm achieves competitive average scores, suggesting higher instructions per clock. Intel counters with more cores and a 5.70 GHz boost clock, but the two end up nearly tied overall. The AMD chip's die size of 2x 70.6 mm² indicates a chiplet design, while Intel's monolithic approach on 10 nm is not sized in the data. Both processors are actively produced, and neither has an unlocked multiplier. The part numbers are distinct: SA4QD for Intel and 100-000001980 for AMD.
