AMD Ryzen AI Max+ 392 vs AMD Ryzen Threadripper 9970X Comparison

The AMD Ryzen AI Max+ 392 and the AMD Ryzen Threadripper 9970X represent two distinct extremes in AMD’s Zen 5 lineup. The data shows the Threadripper 9970X wins every single benchmark in the head-to-head comparison, taking all 11 tests. The Ryzen AI Max+ 392, however, is a mobile part with a 55 W TDP, while the Threadripper is a desktop powerhouse with a 350 W TDP. The benchmark results indicate that the Threadripper’s massive core count and higher clock speeds deliver a decisive performance advantage across the board, but the Ryzen AI Max+ 392 still holds a unique position in the database due to its integrated graphics and much lower power envelope.

The Verdict

The data is unambiguous: the AMD Ryzen Threadripper 9970X is the superior processor in raw performance. It wins all 11 head-to-head benchmarks, with margins ranging from 13.3% in single-threaded tests to 68.9% in random string sorting. The Threadripper’s average benchmark score of 279778 places it in the 99th percentile of all CPUs, while the Ryzen AI Max+ 392 scores 90541 on average, putting it in the 96th percentile. The Threadripper is also the clear choice for heavily threaded workloads, as its multithread score of 107399 is more than double the Ryzen AI Max+ 392’s 45231. For anyone building a high-end desktop workstation, the Threadripper’s 32 cores and 64 threads are the decisive factor.

The Ryzen AI Max+ 392, despite losing every head-to-head test, serves a completely different purpose. It is a mobile processor with a 55 W TDP, which means it is designed for laptops and compact systems where power efficiency matters more than raw throughput. Its integrated Radeon 8060S graphics eliminate the need for a discrete GPU in many scenarios, a feature the Threadripper lacks entirely. The Ryzen AI Max+ 392 also uses LPDDR5X memory with 256.0 GB/s of bandwidth, which is higher than the Threadripper’s 204.8 GB/s with DDR5. This makes the Ryzen AI Max+ 392 a sensible pick for portable, all-in-one systems, while the Threadripper is the obvious choice for stationary, multi-threaded compute tasks.

Architecture Differences

Both processors are built on the Zen 5 architecture and use TSMC’s 4 nm process node, but their physical designs diverge significantly. The Ryzen AI Max+ 392 has 12 cores and 24 threads, while the Threadripper 9970X has 32 cores and 64 threads. The Threadripper uses four dies, each measuring 70.6 mm², totaling 33,260 million transistors. The Ryzen AI Max+ 392 uses two dies of the same 70.6 mm² size. This die configuration directly explains the Threadripper’s higher core count and its larger 128 MB shared L3 cache, compared to the Ryzen AI Max+ 392’s 64 MB shared L3 cache. The L1 cache also differs, with the Ryzen AI Max+ 392 offering 80 KB per core versus the Threadripper’s 64 KB per core, though both share 1 MB of L2 per core.

The memory subsystems and connectivity options are also distinct. The Ryzen AI Max+ 392 supports LPDDR5X over a quad-channel bus, achieving 256.0 GB/s of bandwidth. The Threadripper 9970X supports DDR5 over a quad-channel bus, but its bandwidth is lower at 204.8 GB/s. The Threadripper compensates with PCIe Gen 5 and 80 lanes, while the Ryzen AI Max+ 392 uses PCIe Gen 4 with only 16 lanes. Both processors support ECC memory, but the Threadripper has an unlocked multiplier, enabling overclocking, whereas the Ryzen AI Max+ 392 does not. The Threadripper’s launch MSRP is $2499, a figure that reflects its desktop workstation positioning, while the Ryzen AI Max+ 392 has no listed launch MSRP in the database.

Where Each One Wins

The Threadripper 9970X wins in every workload category recorded in the database. Its most dominant victories are in data compression (1757998 vs 554760, a 68.4% delta), random string sorting (191445 vs 59487, a 68.9% delta), and extended instructions (142342 vs 45666, a 67.9% delta). These are classic multi-threaded tasks where the Threadripper’s 32 cores provide a massive parallel advantage. The Threadripper also leads in integer math (465378 vs 152414, a 67.2% delta) and floating point math (309719 vs 99548, a 67.9% delta), solidifying its position as a computational workhorse.

The Ryzen AI Max+ 392 does not win any benchmark, but its strengths lie outside the PassMark test suite. Its integrated Radeon 8060S graphics are a unique feature for a mobile processor, allowing for GPU-accelerated workloads without a separate card. The higher memory bandwidth of 256.0 GB/s, despite the lower overall performance, suggests that memory-intensive tasks might see relatively better scaling on the Ryzen AI Max+ 392 compared to its other scores. The 55 W TDP is another advantage, as it enables sustained operation in thermally constrained environments. The data indicates the Ryzen AI Max+ 392 is a versatile mobile chip, but its performance ceiling is firmly below the Threadripper’s.
