AMD Ryzen AI Max 385 vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The database shows a stark contrast between these two processors: the AMD Ryzen AI Max 385 has a full suite of recorded benchmark results, while the Intel Core 7 251E has no benchmark scores recorded at all. This means the head-to-head comparison is one-sided, but the available data still provides a complete picture of the AMD part's standing.

The AMD Ryzen AI Max 385 posts a Cinebench R23 multi-core score of 15674 and a single-core score of 2212. In Cinebench R20, it records 6583 multi-core and 929 single-core, while Cinebench R15 shows 1579 multi-core and 222 single-core. These scores place the chip at the 88th percentile among all CPUs in the database, with an average benchmark score of 44309.

The nearest rivals in the database bracket this chip tightly. The Intel Core i9-13950HX sits -0.1% behind with an average score of 44342, while the Intel Core 5 13600 sits +0.2% ahead at 44240. The Intel Core Ultra X9 388H comes in at -0.4% with 44466, and the AMD Ryzen 5 7500X3D is -0.6% with 44573. These delta percentages indicate the Ryzen AI Max 385 sits within a very narrow performance band around its nearest competitors, moving less than one percent in either direction.

PassMark results reinforce this positioning. The multi-thread score is 33705, with integer math at 107046, floating point math at 71105, and extended instructions at 33873. Data compression scores 406505, while data encryption reaches 19926. The single-thread PassMark score is 4060, and random string sorting posts 43725. Find prime numbers scores 165, and physics hits 1889.

The Intel Core 7 251E has zero benchmark entries, zero average score, and zero nearest rivals in the database. Its percentile ranking sits at 50, which is the midpoint by definition rather than a measured result. The data indicates no measured performance exists for this processor, so no direct comparison can be made. The AMD chip's dominance in this head-to-head is entirely a function of data availability, not measured superiority.

Architecture Differences

The two processors come from fundamentally different design families. The AMD Ryzen AI Max 385 uses the Zen 5 architecture under the Strix Halo codename, built on TSMC's 4 nm process. The Intel Core 7 251E uses the Bartlett Lake codename from Intel's Core 7 generation, built on Intel's 10 nm process.

Core counts diverge sharply. AMD provides 8 cores and 16 threads, while Intel provides 24 cores and 32 threads. The Intel part has triple the core count and double the thread count. Both chips lock their multipliers, preventing user overclocking.

Cache hierarchies show similar per-core L1 allocations at 80 KB per core. The L2 cache differs, with AMD using 1 MB per core and Intel using 2 MB per core. Shared L3 cache also differs: AMD provides 32 MB, while Intel provides 36 MB. Intel's larger per-core L2 and slightly larger L3 give it a cache capacity advantage on paper.

Memory architecture presents one of the largest gaps. AMD uses quad-channel LPDDR5X with 256.0 GB/s bandwidth. Intel uses dual-channel DDR4 and DDR5 with 89.6 GB/s bandwidth. AMD's memory bandwidth is roughly 2.86 times Intel's figure. Both support ECC memory.

PCIe connectivity differs by generation. AMD provides Gen 4 with 16 lanes from the CPU. Intel provides Gen 5 with 16 lanes from the CPU. Intel's PCIe generation is newer, though lane counts match.

Integrated graphics also diverge. AMD uses the Radeon 8050S, while Intel uses UHD Graphics 770. The database records no benchmark results for either GPU, so no performance comparison is possible from the data.

The AMD chip uses AMD Socket FP11, a mobile socket, and targets the mobile market segment. The Intel chip uses Intel Socket 1700 and targets the desktop market segment. Production status for both is listed as active.

Where Each One Wins

The AMD Ryzen AI Max 385 wins in the database because it has measured performance data. Its 88th percentile ranking and 44309 average benchmark score are backed by 17 recorded test results. The Intel Core 7 251E has zero recorded results, so it cannot claim any measured win.

AMD's advantages in the recorded specifications are clear. Its 256.0 GB/s memory bandwidth is 2.86 times Intel's 89.6 GB/s. Its 3.60 GHz base clock is substantially higher than Intel's 2.10 GHz. Its 4 nm process node is denser than Intel's 10 nm. Its 55 watt TDP is lower than Intel's 65 watts. These factors point to better power efficiency and memory throughput for the AMD part.

Intel's advantages in the recorded specifications are also clear. Its 24 cores and 32 threads dwarf AMD's 8 cores and 16 threads. Its 5.60 GHz boost clock exceeds AMD's 5.00 GHz. Its 2 MB per-core L2 and 36 MB shared L3 beat AMD's 1 MB per-core L2 and 32 MB shared L3. Its Gen 5 PCIe is newer than AMD's Gen 4. Its desktop socket and market segment target a different usage profile than AMD's mobile socket.

The use-case split follows from these specifications. For heavily threaded workloads that scale with core count, such as rendering, compilation, or server-style tasks, the Intel part's 24 cores and 32 threads provide a structural advantage. The database contains no benchmark scores to confirm this, but the core count difference is recorded fact.

For memory-bandwidth-sensitive workloads, the AMD part's 256.0 GB/s quad-channel LPDDR5X setup provides a large theoretical advantage over Intel's 89.6 GB/s dual-channel setup. This favors the AMD chip for tasks like data movement, large dataset processing, or integrated graphics memory access.

For single-thread performance, Intel's 5.60 GHz boost clock exceeds AMD's 5.00 GHz, suggesting an advantage in lightly threaded tasks. However, AMD's higher 3.60 GHz base clock suggests better sustained performance at lower loads.

The benchmark data, where it exists, favors AMD. The 88th percentile ranking and the narrow delta percentages against the i9-13950HX, i5-13600, Ultra X9 388H, and Ryzen 5 7500X3D show a processor that performs in the upper tier of all CPUs. The Intel part's 50th percentile ranking carries no measured support.

In practical terms, the AMD Ryzen AI Max 385 is the only one of these two processors with empirical evidence in the database. It wins all recorded head-to-head comparisons by default. The Intel Core 7 251E remains a specification-only entry, with its advantages limited to core count, boost clock, cache capacity, and PCIe generation. Any performance verdict on the Intel part must await benchmark data.
