AMD EPYC 8324P vs AMD Ryzen AI Max+ 392 Comparison

The Verdict

The data paints a clear picture of two processors built for entirely different purposes. The AMD EPYC 8324P wins 9 of the 11 head-to-head benchmark comparisons, dominating in every multithreaded and server-oriented workload. The AMD Ryzen AI Max+ 392 wins only 2 comparisons, both being the single-thread test, which it takes by a wide margin of 39.7%. The EPYC 8324P is the choice for heavy server workloads, database operations, and any task that scales across cores. The Ryzen AI Max+ 392 is the pick for single-threaded responsiveness and mobile form factors where power efficiency matters more than raw core count.

The average benchmark score tells the same story. The EPYC 8324P records an average of 103,329 across all benchmark entries, which places it in the 97th percentile of all CPUs in the database. The Ryzen AI Max+ 392 averages 90,541, sitting in the 96th percentile. The difference is roughly 14% in favor of the server chip, yet the Ryzen AI Max+ 392 still ranks nearly as high in overall percentile, which suggests its single-thread excellence and efficiency make it a strong contender in its own class. The EPYC 8324P's nearest rivals include the Intel Xeon 6521P at 2.4% higher average score and the Intel Xeon w7-3555 at 2.7% higher, while it edges out the AMD EPYC 7513 by 1.1% and the AMD Ryzen Threadripper PRO 9955WX by 2.3%. The Ryzen AI Max+ 392 sits within 0.2% of the Intel Xeon 654 and 0.7% of the AMD Ryzen 9 9955HX, while leading the Intel Xeon w7-2575X by 2.7% and the Intel Xeon 6736P by 3%.

Architecture Differences

The EPYC 8324P belongs to the EPYC 8004 series, built on the Zen 4c architecture under the codename Siena, fabricated on a 5 nm process at TSMC. It packs 32 cores and 64 threads, with a base clock of 2.65 GHz and a boost clock of 3.00 GHz. The Ryzen AI Max+ 392 uses the Zen 5 architecture, codenamed Strix Halo, on a 4 nm process, also from TSMC. It has 12 cores and 24 threads, with a much higher base clock of 3.20 GHz and a boost clock of 5.00 GHz. The transistor counts differ significantly: the EPYC 8324P has 35,500 million transistors across a die size of 4x 73 mm², while the Ryzen AI Max+ 392 has no listed transistor count but a die size of 2x 70.6 mm².

Cache hierarchies diverge notably. The EPYC 8324P offers 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of shared L3 cache. The Ryzen AI Max+ 392 has 80 KB of L1 per core, 1 MB of L2 per core, and only 64 MB of shared L3 cache. The larger L3 pool on the server chip likely contributes to its strong performance in data-heavy workloads. Memory support also differs: the EPYC 8324P uses DDR5 with a six-channel memory bus and a bandwidth of 230.4 GB/s, while the Ryzen AI Max+ 392 uses LPDDR5X with a quad-channel bus and a slightly higher bandwidth of 256.0 GB/s. Both support ECC memory, which is unusual for a mobile chip and speaks to the Ryzen AI Max+ 392's workstation ambitions.

PCIe connectivity separates them further. The EPYC 8324P provides Gen 5 with 96 lanes from the CPU, a massive amount for server expansion. The Ryzen AI Max+ 392 offers Gen 4 with only 16 lanes, sufficient for a mobile platform but nowhere near the server chip's expansion capacity. The EPYC 8324P has no integrated graphics, while the Ryzen AI Max+ 392 includes a Radeon 8060S iGPU. The sockets differ as expected: the EPYC 8324P uses AMD Socket SP6, and the Ryzen AI Max+ 392 uses AMD Socket FP11. The TDP gap is enormous, 180 watts for the EPYC 8324P versus 55 watts for the Ryzen AI Max+ 392, and this alone explains much of the performance difference in sustained multithreaded workloads.

Head-to-Head Benchmarks

The EPYC 8324P wins the majority of the head-to-head tests, and several wins are by very large margins. In data compression, the EPYC 8324P scores 980,907 against the Ryzen AI Max+ 392's 554,760, a delta of 76.8%. Data encryption shows an even larger gap: 63,195 versus 27,784, a 127.5% advantage for the server chip. Random string sorting is another dominant win, with the EPYC 8324P at 113,610 versus 59,487, a 91% delta. Integer math follows at 248,447 versus 152,414, a 63% edge. Physics simulation goes to the EPYC 8324P by 60.6%, with scores of 4,637 versus 2,887. Floating point math shows a 39.7% lead for the EPYC 8324P, scoring 139,022 against 99,548. Extended instructions favor the EPYC 8324P by 32.1%, 60,304 versus 45,666. The multithread test gives the EPYC 8324P a 26.3% win, 57,127 versus 45,231. Even find prime numbers, the closest test overall, goes to the EPYC 8324P by 8.4%, 347 versus 320.

The Ryzen AI Max+ 392's only wins come in the single-thread tests, where it scores 3,927 against the EPYC 8324P's 2,367, a 39.7% advantage. This is a striking reversal given the server chip's dominance elsewhere. The higher boost clock of 5.00 GHz versus 3.00 GHz and the newer Zen 5 architecture explain the single-thread superiority. The data indicates that the Ryzen AI Max+ 392 is the more responsive chip for latency-sensitive, single-threaded tasks, while the EPYC 8324P is the throughput king for parallel workloads.

Where Each One Wins

The EPYC 8324P wins in every multithreaded and throughput-oriented category. Data compression, encryption, integer math, floating point math, physics, extended instructions, random string sorting, multithread, and even prime number finding all favor the server chip. This makes it the clear choice for server racks, virtualization hosts, database servers, and any workload that can utilize 32 cores and 64 threads. The 128 MB of shared L3 cache and 96 PCIe Gen 5 lanes further cement its position for high-density compute environments. The six-channel DDR5 memory configuration with 230.4 GB/s bandwidth supports heavy memory traffic typical of enterprise applications.

The Ryzen AI Max+ 392 wins in single-threaded performance by a significant margin, making it the better option for applications that rely on fast per-core response times. Its 55 watt TDP, integrated Radeon 8060S graphics, and mobile Socket FP11 form factor indicate a design goal of power-efficient, compact systems. The 256.0 GB/s memory bandwidth from LPDDR5X is actually higher than the EPYC 8324P's 230.4 GB/s, which is notable for a mobile chip. The 96th percentile ranking, despite far fewer cores, shows that the Zen 5 architecture and 5.00 GHz boost clock deliver excellent performance per watt. For mobile workstations, compact desktops, or any scenario where single-thread responsiveness and power efficiency take priority over raw core count, the Ryzen AI Max+ 392 is the data-backed choice.
