Architecture Differences

Both processors are built on Zen 5 architecture and manufactured by TSMC on a 4 nm process node. The underlying core design is shared, but the implementation differs substantially in scale and purpose.

The AI Max+ 388 uses the Strix Halo codename and belongs to the Ryzen AI Max generation. It packs 8 cores and 16 threads into an AMD Socket FP11 package. The chip has a die size listed as 2x 70.6 mm², with 80 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. It supports LPDDR5X memory across a quad-channel bus, delivering 256.0 GB/s of bandwidth. The integrated Radeon 8060S graphics means the processor does not require a discrete GPU for display output. The PCIe interface is Gen 4 with 16 lanes available from the CPU. The market segment is mobile, and the multiplier is locked.

The Threadripper 9980X uses the Shimada Peak codename and belongs to the Ryzen Threadripper generation in the 9000 series. It expands to 64 cores and 128 threads on AMD Socket sTR5. The die configuration is 8x 70.6 mm² and the transistor count is 66,520 million. L1 cache is 64 KB per core, L2 is 1 MB per core, and L3 is 256 MB. Memory support is DDR5 with a quad-channel bus at 204.8 GB/s. The PCIe interface is Gen 5 with 80 lanes from the CPU, a substantial upgrade in both generation and lane count. The integrated graphics field is N/A, so a discrete GPU is required. The market segment is desktop, and the multiplier is unlocked, allowing user overclocking. The production status for both parts is active.

The AI Max+ 388 has a TDP of 55, which reflects its mobile orientation. The Threadripper 9980X has a TDP of 350, a figure consistent with a high-core-count desktop workstation part. The release dates differ: the Threadripper 9980X launched on 2025-07-29, while the AI Max+ 388 has a release date of 2026-01-05.

The Verdict

The benchmark data presents a clear division of roles. The Threadripper 9980X dominates every recorded benchmark, with multi-thread deltas ranging from -76.4% to -87.4%. The average benchmark score of 321753 places it in the 99th percentile, and its nearest rivals are other high-end workstation and server parts. The AI Max+ 388, with an average score of 49796 in the 90th percentile, competes in a different tier, sitting near the Intel Core 9 273PE and ahead of the Intel Core i5-14600KF by 0.8%.

For workloads that scale with core count, the Threadripper 9980X is the only choice between these two. The 64-core design delivers roughly 7 to 8 times the multi-thread throughput across Cinebench and PassMark tests. Data compression, encryption, integer math, floating point math, and extended instruction workloads all show deltas greater than 85%. The 256 MB of L3 cache and 80 PCIe Gen 5 lanes further support heavy compute and data movement scenarios.

The AI Max+ 388 is the more efficient mobile option. Its 55 TDP, integrated Radeon 8060S graphics, and 256.0 GB/s memory bandwidth suit a compact system where space and power are constrained. The single-thread PassMark result is only 7.8% behind the Threadripper, so lightly threaded tasks will not feel dramatically slower. The 90th percentile standing confirms it is a capable processor in its own right, just not in the same class as the Threadripper.

The launch MSRP for the Threadripper 9980X is $4999. The AI Max+ 388 has no launch MSRP recorded in the database.
