AMD Ryzen AI Max 390 vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD Ryzen AI Max 390 across all 17 head-to-head benchmark comparisons, with the Intel Core 7 253PE failing to secure a single win. The margin varies dramatically by workload, revealing where each architecture's strengths and weaknesses lie.

In the Cinebench suite, the AMD part delivers a consistent advantage. The R15 multicore test shows AMD scoring 3635 against Intel's 2507, a 45% difference. The R20 multicore result repeats the pattern almost exactly: 15146 versus 10449, again 45%. R23 multicore follows suit with 36064 against 24880, another 45% gap. Single-core results are equally lopsided: R15 single-core shows 513 versus 354 (44.9%), R20 single-core shows 2138 versus 1475 (44.9%), and R23 single-core shows 5091 versus 3512 (45%). The consistency of these deltas across the entire Cinebench family suggests a fundamental throughput advantage rather than a workload-specific quirk.

The PassMark suite paints a more nuanced picture. The largest single margin appears in PassMark find prime numbers, where AMD scores 316 against Intel's 138, a 129% advantage. This test heavily favors the Zen 5 core design. Extended instructions show the second-largest gap: 38716 versus 21806, a 77.5% difference. Random string sorting shows 53113 versus 32777, a 62% delta. Physics tests show 2761 versus 1845, a 49.6% gap. Data compression shows 487145 versus 339133, a 43.6% difference, while multithreaded performance shows 41737 versus 29271, a 42.6% gap.

The narrowest margin appears in PassMark single-thread performance: 4028 versus 3955, only a 1.8% difference. This is the only test where the two processors are nearly comparable. Floating-point math shows a moderate 12% gap (90594 versus 80870), while integer math shows 28.3% (146519 versus 114158). Data encryption shows 36.5% (25097 versus 18385).

The average benchmark score reinforces the overall picture. AMD's average sits at 56273, placing it in the 91st percentile of all CPUs in the database. Intel's average is 40557, good for the 87th percentile. The AMD part edges closer to its nearest rival, the AMD Ryzen AI 9 HX PRO 470, which averages 56306 (a 0.1% delta). Intel's nearest rival, the Intel Core 5 223PE, averages 40585, a 0.1% delta in the other direction.

The Verdict

The data is unambiguous: the AMD Ryzen AI Max 390 wins every single benchmark comparison against the Intel Core 7 253PE. For users looking strictly at measured performance, the AMD part is the superior choice across all tested workloads. The percentile ranking (91 versus 87) and the 28.7% average score difference (56273 versus 40557) confirm that this is not a marginal victory but a systematic one.

The Intel Core 7 253PE does hold one notable distinction: it carries a launch MSRP of $384. The AMD part has no recorded launch MSRP in the database. Beyond that pricing fact, the Intel part cannot claim any performance advantage in the recorded measurements.

For workloads that stress single-thread performance, the gap narrows to just 1.8%, meaning the Intel part is nearly competitive in that specific area. However, for every multithreaded, encryption, compression, or prime-number-finding task, the AMD part leads by margins ranging from 12% to 129%. The verdict from the database is straightforward: AMD delivers the higher performance in this comparison, with the only question being whether the Intel part's pricing structure matters to a buyer, which falls outside the scope of this analysis.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Max 390 uses the Zen 5 architecture on the Strix Halo codename, built on a 4 nm process by TSMC. The Intel Core 7 253PE uses the Bartlett Lake codename, built on a 10 nm process by Intel's own foundry. The process node difference (4 nm versus 10 nm) helps explain why AMD achieves higher performance at a lower TDP.

Cache hierarchies differ substantially. Both parts share 80 KB of L1 cache per core, but the AMD part uses 1 MB of L2 per core while Intel uses 2 MB per core. The L3 cache shows a major divergence: AMD provides 64 MB shared, while Intel provides 33 MB shared. That 31 MB difference in L3 capacity likely contributes to AMD's advantage in data compression and random string sorting tests, which benefit from larger working sets residing closer to the cores.

The AMD part uses a dual-die design with a die size of 2x 70.6 mm². Intel's die size is not recorded in the database. The memory architecture also differs: AMD supports LPDDR5X with a quad-channel memory bus delivering 256.0 GB/s of bandwidth, while Intel supports DDR4 and DDR5 with a dual-channel bus delivering 89.6 GB/s. This 166.4 GB/s bandwidth gap is one of the largest architectural differences and directly impacts memory-intensive workloads.

PCIe support differs as well. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The newer PCIe generation on the Intel side allows for faster peripheral connectivity, though this does not appear in the CPU benchmark results. Both parts support ECC memory, and neither has an unlocked multiplier.

Integrated graphics diverge significantly. AMD includes the Radeon 8050S, while Intel includes the UHD Graphics 730. The database records no graphics benchmarks, so the performance implications cannot be quantified here.

Specification Differences

The core and thread counts differ: AMD offers 12 cores and 24 threads, while Intel offers 10 cores and 20 threads. This 2-core, 4-thread advantage for AMD directly translates into the multicore benchmark wins.

Clock speeds tell a mixed story. AMD's base clock is 3.20 GHz with a boost clock of 5.00 GHz. Intel's base clock is 2.50 GHz with a boost clock of 5.50 GHz. Intel's higher boost clock (0.5 GHz higher) does not overcome AMD's higher base clock (0.7 GHz higher) in the single-thread tests, where AMD still leads by 1.8% in PassMark and 45% in Cinebench R23.

TDP ratings differ: AMD is rated at 55 W, while Intel is rated at 65 W. The AMD part delivers higher performance at a lower thermal envelope, a direct consequence of the more advanced 4 nm process.

Socket and market segment differ completely. AMD uses the FP11 socket and targets the mobile segment. Intel uses the LGA 1700 socket (recorded as Socket 1700) and targets the desktop segment. Release dates also differ: AMD was released on 2025-01-05, while Intel was released on 2026-03-08, over a year later.

The part numbers differ: AMD's is 100-000001423, Intel's is SA4QE. The memory support, memory bus width, memory bandwidth, PCIe generation, integrated graphics, and cache allocations all differ as previously detailed. The launch MSRP for Intel is $384; AMD has no recorded launch MSRP.

Where Each One Wins

The AMD Ryzen AI Max 390 wins in every recorded benchmark category, so the "where each one wins" section is a matter of degree rather than kind. The AMD part shows its largest advantages in prime number finding (129%), extended instructions (77.5%), and random string sorting (62%). These workloads rely heavily on the larger L3 cache (64 MB versus 33 MB) and the higher memory bandwidth (256.0 GB/s versus 89.6 GB/s).

For floating-point math, the AMD advantage shrinks to 12%, suggesting the Intel part's 2 MB per-core L2 cache helps close the gap in this specific workload. The single-thread PassMark test shows only a 1.8% difference, indicating that for lightly threaded integer tasks, the Intel part's higher boost clock (5.50 GHz versus 5.00 GHz) nearly compensates for the architectural differences.

The Intel Core 7 253PE does not win any benchmark in the database. Its advantages are limited to non-benchmark specifications: PCIe Gen 5 support versus AMD's Gen 4, a higher boost clock (5.50 GHz versus 5.00 GHz), a desktop socket (LGA 1700 versus FP11), and a later release date (2026-03-08 versus 2025-01-05). The Intel part also supports DDR4 memory in addition to DDR5, which may matter for system compatibility, though this is not reflected in the benchmark scores.

For users prioritizing any measured performance metric, the AMD Ryzen AI Max 390 is the clear choice from the data. The Intel part's only recorded advantage is the launch MSRP of $384, which is a pricing consideration outside the scope of performance analysis. The database records 17 benchmark wins for AMD and 0 for Intel, with the average benchmark score favoring AMD by 28.7%. The percentile ranking (91st versus 87th) confirms that the AMD part sits higher in the overall CPU performance distribution.
