AMD EPYC 7443P vs AMD Ryzen AI Max+ 392 Comparison

The AMD Ryzen AI Max+ 392 and AMD EPYC 7443P occupy opposite ends of the processor spectrum. The Ryzen AI Max+ 392 is a 12-core mobile part built on Zen 5 (Strix Halo) with a 4 nm process, while the EPYC 7443P is a 24-core server chip on Zen 3 (Milan) with a 7 nm process. Both sit at the 96th percentile of all CPUs in the database, but their benchmark profiles diverge sharply. The Ryzen AI Max+ 392 posts a higher average benchmark score (90541) than the EPYC (81661), yet the EPYC wins 9 of 11 head-to-head PassMark tests. This is a tale of single-thread agility versus multi-thread brute force.

The Verdict

Pick the AMD EPYC 7443P if your workload scales across many cores. It wins the PassMark multithread test with 56981 against 45231, a 20.6% margin, and dominates data compression (820859 vs 554760, 32.4% ahead), encryption (57263 vs 27784, 51.5% ahead), integer math (232632 vs 152414, 34.5% ahead), and physics (4748 vs 2887, 39.2% ahead). The EPYC also leads in floating point, random string sorting, extended instructions, and prime number finding. Its 24 cores and 48 threads, combined with 128 MB of L3 cache and eight-channel DDR4 memory, make it the clear choice for server, workstation, and heavily threaded compute tasks. The EPYC's nearest rivals in the database include the Intel Core i9-14900KS, Intel Xeon w5-3535X, and AMD Ryzen 9 8940HX, all within 0.7% of its average score, but its PassMark wins here are decisive.

Pick the AMD Ryzen AI Max+ 392 if single-thread performance and platform integration matter more. It wins the PassMark single-thread test with 3927 against 2907, a 35.1% advantage. It also has a higher boost clock (5.00 GHz vs 4.00 GHz), a newer 4 nm process, integrated Radeon 8060S graphics, and a much lower 55 W TDP compared to the EPYC's 200 W. For mobile or compact systems where power and space are limited, the Ryzen AI Max+ 392 is the practical option. Its average benchmark score of 90541 also exceeds the EPYC's 81661, though that aggregate includes a broader set of tests beyond the PassMark suite. The Ryzen's nearest rivals include the Intel Xeon 654 (0.2% behind) and AMD Ryzen 9 9955HX (0.7% behind), showing it competes well in its segment.

Architecture Differences

The two chips come from different architectural generations. The Ryzen AI Max+ 392 uses Zen 5 cores on a 4 nm TSMC process, with a die size of 2x 70.6 mm². The EPYC 7443P uses Zen 3 cores on a 7 nm TSMC process, with a die size of 4x 81 mm² and 16,600 million transistors. The Ryzen's L1 cache is 80 KB per core, L2 is 1 MB per core, and L3 is 64 MB shared. The EPYC has 64 KB L1 per core, 512 KB L2 per core, and 128 MB shared L3. Memory support differs: the Ryzen uses LPDDR5X over a quad-channel bus, while the EPYC uses DDR4 over an eight-channel bus. The Ryzen has 16 PCIe Gen 4 lanes (CPU only), while the EPYC has 128 PCIe Gen 4 lanes. The Ryzen integrates a Radeon 8060S GPU; the EPYC has none. The Ryzen is built for the FP11 socket, the EPYC for SP3. These architectural differences explain the benchmark split: the EPYC's larger core count and cache benefit multi-threaded workloads, while the Ryzen's newer process and higher clocks boost single-thread performance.

Head-to-Head Benchmarks

The PassMark suite reveals a clear pattern. The EPYC 7443P wins 9 of 11 tests, with the largest margins in data encryption (51.5% ahead: 57263 vs 27784), integer math (34.5% ahead: 232632 vs 152414), random string sorting (37.8% ahead: 95581 vs 59487), and physics (39.2% ahead: 4748 vs 2887). Data compression also goes to the EPYC by 32.4% (820859 vs 554760). The EPYC leads in floating point math by 23.4% (129932 vs 99548), find prime numbers by 22% (410 vs 320), multithread by 20.6% (56981 vs 45231), and extended instructions by 5.3% (48213 vs 45666). The only wins for the Ryzen AI Max+ 392 are the single-thread and singlethread tests, both scoring 3927 against 2907, a 35.1% advantage. These results show that the EPYC's extra cores and larger cache dominate throughput-oriented tasks, while the Ryzen's higher boost clock and newer architecture deliver superior per-thread performance.

Where Each One Wins

The AMD EPYC 7443P is the winner for server and workstation workloads that can use many threads. Its 24 cores and 48 threads, 128 MB L3 cache, and eight-channel DDR4 memory give it decisive leads in data compression, encryption, integer math, physics, and random string sorting. The 51.5% encryption advantage and 39.2% physics lead are particularly strong for database, scientific, and financial applications. The EPYC also has 128 PCIe Gen 4 lanes, making it suitable for high-throughput I/O systems. Its launch MSRP of $1337 reflects its server positioning.

The AMD Ryzen AI Max+ 392 wins where single-thread speed and platform integration matter. Its 35.1% single-thread lead (3927 vs 2907) makes it better for lightly threaded applications, and its integrated Radeon 8060S GPU eliminates the need for a discrete graphics card. The 55 W TDP and 4 nm process make it far more power-efficient, and its 256.0 GB/s memory bandwidth (higher than the EPYC's 204.8 GB/s) benefits memory-sensitive tasks. The Ryzen also has a higher average benchmark score (90541 vs 81661) and sits within 0.7% of the AMD Ryzen 9 9955HX and 0.2% of the Intel Xeon 654 in the database's nearest rival list. For mobile or compact systems, the Ryzen AI Max+ 392 is the clear choice.

In summary, the EPYC 7443P is the multi-threaded workhorse, while the Ryzen AI Max+ 392 is the single-thread specialist with integrated graphics and low power draw. Choose based on your workload's core scaling and platform requirements.
