AMD Ryzen AI Max+ PRO 395 vs Intel Xeon 6731P Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Xeon 6731P and the AMD Ryzen AI Max+ PRO 395 reveals a stark split in workload characteristics. Out of 15 recorded head-to-head tests, the Intel Xeon 6731P claims 12 victories, while the AMD Ryzen AI Max+ PRO 395 secures 3. The most dramatic Intel victory comes in Cinebench R23 single-core, where it scores 6334 against AMD's 2012.5, a 214.7% margin. This is not a subtle difference; it suggests a fundamental advantage in lightly threaded performance that the AMD chip cannot offset.

The Intel Xeon 6731P also dominates in Cinebench R15 single-core with a 108.5% delta (638 vs 306), and in PassMark physics with a 122.8% lead (7105 vs 3189). The prime number test shows a 90.5% gap (541 vs 284), further highlighting Intel's strength in integer-heavy single-thread workloads. Floating-point math also goes decisively to Intel, with a 30.5% advantage (157330 vs 120533).

However, the AMD Ryzen AI Max+ PRO 395 wins the most popular synthetic multi-threaded test, Cinebench R15 multicore, with a score of 5247 against 4522, a 13.8% lead. The AMD chip also dominates PassMark single-thread, scoring 4078 versus 2107, a 48.3% advantage. This is a curious result, as the Cinebench single-core tests show the opposite, suggesting the two suites measure different aspects of single-thread responsiveness.

In the broader multi-core arena, the Intel Xeon 6731P takes Cinebench R23 multicore with 44871 against 35061, a 28% lead. The data compression test goes to Intel by 25% (799474 vs 639356), and data encryption by 22.1% (40087 vs 32840). Extended instructions favor Intel by 26.1% (65656 vs 52067). The integer math test is the closest overall, with Intel only 4.2% ahead (198761 vs 190720). The multithread PassMark score is also tight, with Intel ahead by just 2.5% (52790 vs 51502). Random string sorting goes to Intel by 25.5% (88019 vs 70150). The data clearly shows Intel's lead is not uniform, but it is consistent across a broad set of server-oriented workloads.

Architecture Differences

The architectural contrast is stark. The Intel Xeon 6731P is built on Granite Rapids architecture, using Intel's 5 nm process with a die size of 598 mm². It is a server/workstation part housed in the Intel Socket 4710. The AMD Ryzen AI Max+ PRO 395 is a Zen 5 architecture part, fabricated on TSMC's 4nm node, fitting into AMD Socket FP11, and is aimed at the mobile segment. The process node difference is small (5nm vs 4nm), but the design philosophy is radically different.

The core count disparity is significant. Intel provides 32 cores and 64 threads, while AMD offers 16 cores and 32 threads. The Xeon has a base clock of 2.50 GHz and a boost clock of 4.10 GHz, whereas the Ryzen has a higher base of 3.00 GHz and a boost of 5.10 GHz. The Intel's lower clock speed is offset by its massive core count.

Cache hierarchies also diverge. Intel's L1 cache is 112 KB per core, with 2 MB L2 per core, and the L3 cache is a large 144 MB shared. AMD has a smaller 80 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3. The Xeon's 144 MB L3 is more than double the AMD's 64 MB, which directly contributes to its lead in data compression and encryption benchmarks.

Memory support differs as well. Intel uses DDR5 with an eight-channel memory bus, providing 409.6 GB/s of bandwidth. AMD uses LPDDR5X with a quad-channel bus, yielding 256.0 GB/s. The Intel has more than 1.6 times the memory bandwidth. Both support ECC memory. PCIe connectivity is also one-sided: Intel offers Gen 5 with 136 lanes (CPU only), while AMD has Gen 4 with 16 lanes (CPU only). The integrated graphics story also separates them: Intel has N/A, while AMD includes a Radeon 8060S iGPU.

FAQ

Q: Which processor has more cores?

A: The Intel Xeon 6731P has 32 cores and 64 threads, while the AMD Ryzen AI Max+ PRO 395 has 16 cores and 32 threads. The Intel has double the core and thread count.

Q: In which benchmark does the AMD Ryzen AI Max+ PRO 395 actually beat the Intel Xeon 6731P?

A: The AMD wins in three tests: Cinebench R15 multicore (5247 vs 4522, a 13.8% lead) and PassMark single-thread (4078 vs 2107, a 48.3% lead, which appears twice in the data, as passmark_single_thread and passmark_singlethread).

Q: Why does the Intel Xeon 6731P have such a high score in data compression?

A: The Intel Xeon 6731P scored 799474 in PassMark data compression, 25% higher than the AMD's 639356. This likely relates to its larger L3 cache (144 MB vs 64 MB) and higher thread count (64 vs 32), which lets it handle more compression tasks in parallel.

Q: Which processor has a faster boost clock?

A: The AMD Ryzen AI Max+ PRO 395 has a boost clock of 5.10 GHz, which is higher than the Intel Xeon 6731P's 4.10 GHz. The AMD also has a higher base clock (3.00 GHz vs 2.50 GHz).

Q: Is there any integrated graphics on either of these chips?

A: The Intel Xeon 6731P has no integrated graphics (N/A). The AMD Ryzen AI Max+ PRO 395 includes a Radeon 8060S integrated GPU, making it self-sufficient for display output.

Q: What is the memory bandwidth difference?

A: The Intel Xeon 6731P provides 409.6 GB/s through its eight-channel DDR5 memory bus. The AMD Ryzen AI Max+ PRO 395 provides 256.0 GB/s through its quad-channel LPDDR5X bus. The Intel has a 153.6 GB/s bandwidth advantage.

Where Each One Wins

The Intel Xeon 6731P is built for heavy, parallel, and data-intensive workloads. Its 32 cores dominate multi-threaded tests like Cinebench R23 multicore (28% ahead) and Cinebench R15 multicore (13.8% behind, but that is its only multi-core loss). In every other multi-core test, it wins. Data compression, encryption, extended instructions, physics, floating-point math, and random string sorting all go to Intel by margins ranging from 4.2% to 122.8%. The massive 144 MB L3 cache and 409.6 GB/s memory bandwidth make it ideal for server databases, large-scale virtualization, and scientific simulation where cache-resident data and memory throughput are critical. The 136 PCIe Gen 5 lanes offer extensive I/O for storage and networking cards.

The AMD Ryzen AI Max+ PRO 395's wins are different. It wins Cinebench R15 multicore with a 13.8% lead, which is notable but does not represent its overall trend. It also wins PassMark single-thread and single-thread by a huge 93.5% margin (4078 vs 2107). This makes it the better choice for applications that are strictly single-threaded, such as classic desktop productivity tasks, or for workloads that cannot scale across many cores. Its 5.10 GHz boost clock and 3.00 GHz base clock are higher than the Intel's, which explains its single-thread advantage. However, its 16 cores and 64 MB L3 cache limit its performance in the same parallel tasks where the Xeon excels. The presence of the Radeon 8060S iGPU also makes it a candidate for lightweight graphics or compute without a discrete GPU.

The Verdict

The data points to a clear division of labor. The Intel Xeon 6731P is the processor for throughput-heavy, multi-threaded server environments. It wins 12 out of 15 head-to-head tests, including every PassMark multi-threaded calculation and all cryptographic and compression tests. Its 32 cores and 144 MB of L3 cache, paired with 409.6 GB/s of memory bandwidth, make it the unquestioned leader in the benchmark database for these tasks. Its 96th percentile ranking versus all CPUs, and its average benchmark score of 87756, places it in the top tier of processors.

The AMD Ryzen AI Max+ PRO 395, with its 16 cores and 55 W TDP, is a mobile-oriented chip that excels in single-threaded performance. Its PassMark single-thread score of 4078 is nearly double the Xeon's 2107, and it even wins the Cinebench R15 multicore test. However, its 95th percentile and average score of 80762 show it is slightly lower in the overall ranking. The AMD is the choice when portability and single-threaded speed are paramount, but it must contend with the fact that it loses to the Xeon in the majority of the tested workloads. The Xeon is the safer bet for a server room; the AMD is the one to consider for a high-end mobile workstation with CPU-bound single-threaded tasks. The Intel's 28% win in Cinebench R23 multicore is a definitive statement for multi-core, while the AMD's 48.3% win in PassMark single-thread is equally definitive for single-thread. The choice depends on which of those two patterns matters more.
