AMD Ryzen AI Max PRO 485 vs AMD Ryzen Threadripper 9980X Comparison

Where Each One Wins

The AMD Ryzen AI Max PRO 485 and the AMD Ryzen Threadripper 9980X occupy opposite ends of the compute spectrum, and the recorded data reflects entirely different design goals. The Threadripper 9980X is a 64-core, 128-thread desktop processor built for sustained multi-threaded throughput. The Ryzen AI Max PRO 485 is an 8-core, 16-thread mobile processor with integrated graphics, aimed at portable productivity and single-thread responsiveness.

The Threadripper 9980X wins every multi-threaded workload in the database. Its Cinebench R23 multi-core score of 130,529 dwarfs what any 8-core mobile chip can produce. The PassMark multithread score of 141,641 further confirms this dominance. For rendering, scientific computing, video encoding, or any heavily parallel task, the Threadripper is the clear winner based on the benchmark results.

The Ryzen AI Max PRO 485, while lacking a benchmark entry in the database, is positioned for scenarios where the Threadripper cannot operate at all. The Threadripper 9980X has no integrated graphics and requires a dedicated GPU. The Ryzen AI Max PRO 485 includes a Radeon 8050S integrated GPU, making it a complete platform in a mobile form factor. Its 55 W TDP and FP11 socket target laptops and compact systems where the Threadripper's 350 W TDP and sTR5 socket are physically impossible to deploy.

The data shows a clean split: the Threadripper 9980X is for maximum parallel compute in a desktop chassis, while the Ryzen AI Max PRO 485 is for portable, power-constrained systems that still need modern Zen 5 performance. The Threadripper's 99th percentile ranking among all CPUs versus the Ryzen AI Max PRO's 50th percentile ranking quantifies this gap in absolute performance terms.

Architecture Differences

Both processors use the Zen 5 architecture on TSMC's 4 nm process node, but they diverge significantly in implementation. The Ryzen AI Max PRO 485 uses the codename Gorgon Halo and integrates 8 cores with a die size of 70.6 mm². The Threadripper 9980X, codename Shimada Peak, uses 8 chiplets, each 70.6 mm², totaling 66,520 million transistors across the package. This chiplet design allows the Threadripper to scale to 64 cores while maintaining the same per-chiplet process node.

Cache hierarchies differ substantially. The Ryzen AI Max PRO 485 has 80 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The Threadripper 9980X has 64 KB of L1 per core, 1 MB of L2 per core, and a massive 256 MB of L3 cache. The Threadripper's 8x larger L3 pool is critical for workloads that repeatedly access large datasets, reducing memory traffic and improving throughput.

Memory subsystems also differ. The Ryzen AI Max PRO 485 supports LPDDR5X memory with quad-channel bus and 273.1 GB/s of bandwidth. The Threadripper 9980X supports DDR5 memory, also quad-channel, but with 204.8 GB/s of bandwidth. The mobile chip's higher bandwidth figure is notable, but the Threadripper's lower bandwidth is compensated by its enormous core count and cache capacity.

PCIe connectivity shows a major gap. The Ryzen AI Max PRO 485 provides Gen 4 with 16 lanes from the CPU. The Threadripper 9980X provides Gen 5 with 80 lanes. This gives the Threadripper far more headroom for multiple GPUs, high-speed NVMe storage, and expansion cards. The mobile chip's 16 lanes are sufficient for a laptop's discrete GPU and one or two SSDs, but cannot match the desktop platform's expansion capacity.

The Threadripper 9980X has an unlocked multiplier for overclocking, while the Ryzen AI Max PRO 485 is locked. Both support ECC memory, which is relevant for workstation reliability. The Threadripper is a Desktop market segment part with a release date of July 2025, while the Ryzen AI Max PRO 485 is a Mobile part released in May 2026.

Head-to-Head Benchmarks

The database contains benchmark scores only for the Threadripper 9980X, so direct comparisons must rely on the recorded Threadripper results and the architectural specifications of the Ryzen AI Max PRO 485. The Threadripper's Cinebench R23 multi-core score of 130,529 represents the highest multi-threaded result in the database for this processor. Its single-core score of 18,427 in the same test shows strong per-thread performance as well.

The Threadripper 9980X's PassMark results provide a detailed profile of its workload-specific strengths. The data compression score of 2,974,534 is exceptionally high, indicating strong integer throughput and cache efficiency. The floating point math score of 559,003 and integer math score of 872,071 both reflect the benefit of 64 Zen 5 cores. The extended instructions score of 228,959 shows solid AVX-512 or similar vector processing capability. The random string sorting score of 292,083 demonstrates memory subsystem performance under scattered access patterns.

The physics score of 8,001 and find prime numbers score of 769 are lower relative to the other PassMark metrics, which is typical for massively parallel processors where certain algorithms do not scale perfectly. The single-thread score of 4,537 indicates that even a single Zen 5 core in the Threadripper is competitive with modern desktop CPUs.

Relative to its nearest rivals in the database, the Threadripper 9980X holds a narrow lead. It is 0.3% ahead of the AMD Ryzen Threadripper PRO 9985WX, which has an average score of 320,749 versus the 9980X's 321,753. It leads the Intel Xeon 6781P by 2%, the AMD EPYC 9575F by 3.2%, and the AMD EPYC 9734 by 3.6%. These margins are small in percentage terms, suggesting that the 9980X sits at the top of a tightly clustered group of high-end workstation and server processors.

The Ryzen AI Max PRO 485 has no recorded benchmark scores, so its performance must be inferred from its core count, clock speeds, and cache configuration. With 8 cores at a 5.00 GHz boost clock, it should deliver strong single-thread performance, but its multi-threaded output will be roughly 8x lower than the Threadripper's 64 cores, assuming similar IPC. The Threadripper's base clock of 3.20 GHz and boost of 5.40 GHz are both within reach of the mobile chip's 3.60 GHz base and 5.00 GHz boost, indicating that per-core performance is comparable.
