Analysis: AMD Ryzen AI 9 365 vs AMD Ryzen Threadripper 9980X
The AMD Ryzen AI 9 365 and the AMD Ryzen Threadripper 9980X represent two vastly different poles of AMD’s Zen 5 architecture. The former is a 28-watt mobile processor designed for thin-and-light laptops, while the latter is a 350-watt desktop monster aimed at workstation and server-class workloads. The benchmark data is unequivocal: the Threadripper 9980X wins all 15 recorded head-to-head comparisons, with the AI 9 365 trailing by margins that range from a modest 15.3% to a crushing 89.2%. This analysis examines where each chip excels, the architectural gulf between them, and what the recorded scores imply for real-world task segmentation.
Where Each One Wins
The recorded data shows a complete sweep for the AMD Ryzen Threadripper 9980X across every single benchmark category. There are zero wins recorded for the AMD Ryzen AI 9 365, so the use-case split is defined not by which chip wins any given test, but by the magnitude of the Threadripper’s victory and the context of the AI 9 365’s mobile segment.
The Threadripper 9980X dominates in every multi-threaded workload. Its most extreme lead appears in Cinebench R23 multi-core, where it scores 130,529 against the AI 9 365’s 18,698, a delta of -85.7% for the mobile part. Similarly, in PassMark multi-thread, the Threadripper posts 141,641 versus 29,467, a 79.2% gap. These results indicate that any workload that scales with core count, such as video rendering, 3D scene compilation, or scientific simulation, belongs entirely to the Threadripper. The 64-core, 128-thread configuration simply overwhelms the 10-core, 20-thread mobile chip.
The AI 9 365’s only relative strength appears in single-threaded performance, though it still loses. In PassMark single-thread, the AI 9 365 scores 3,841 against the Threadripper’s 4,537, a 15.3% deficit. This is the smallest margin across all tests, indicating that the mobile chip’s Zen 5 cores are competitive on a per-thread basis, but the Threadripper’s higher boost clock of 5.40 GHz versus 5.00 GHz still gives it the edge. For lightly threaded tasks like web browsing, office productivity, or single-core application responsiveness, the AI 9 365 would feel nearly as fast, but the data does not show it winning any of these scenarios.
Architecture Differences
Both processors are built on TSMC’s 4 nm process node and share the Zen 5 architecture, but the similarities end there. The AMD Ryzen AI 9 365 uses the Strix Point codename and belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. It has 10 cores and 20 threads, a base clock of 2.00 GHz, and a boost clock of 5.00 GHz. The Threadripper 9980X, codenamed Shimada Peak, is part of the 9000 series and features a pure Zen 5 (Shimada Peak) design with 64 cores and 128 threads, a base clock of 3.20 GHz, and a boost clock of 5.40 GHz.
The cache hierarchy diverges sharply. The AI 9 365 has 80 KB of L1 per core, 1 MB of L2 per core, and a total of 16 MB of L3 cache. The Threadripper 9980X has 64 KB of L1 per core, also 1 MB of L2 per core, but a massive 256 MB of L3 cache. The die size also tells the story: the AI 9 365 is a monolithic 233 mm² die, while the Threadripper 9980X uses eight separate 70.6 mm² chiplets, totaling 66,520 million transistors. This chiplet design is what enables the Threadripper to pack 64 cores while maintaining a reasonable manufacturing yield.
Memory support is another major divide. The AI 9 365 supports DDR5 and LPDDR5X over a dual-channel memory bus, providing 89.6 GB/s of bandwidth. The Threadripper 9980X supports DDR5 over a quad-channel bus, delivering 204.8 GB/s. The Threadripper also supports ECC memory, while the AI 9 365 does not. PCIe connectivity follows the same pattern: the AI 9 365 offers Gen 4 with 16 lanes, while the Threadripper 9980X provides Gen 5 with 80 lanes. The AI 9 365 includes integrated Radeon 880M graphics, whereas the Threadripper has no integrated graphics at all.

Head-to-Head Benchmarks
The largest margin of victory for the Threadripper 9980X appears in Cinebench R23 single-core, where it scores 18,427 against the AI 9 365’s 1,992, a delta of -89.2%. This is surprising because single-core tests usually favor higher clock speeds, and the Threadripper’s 5.40 GHz boost is only 0.40 GHz higher than the AI 9 365’s 5.00 GHz. The massive gap suggests that the Threadripper’s architecture, with its larger L3 cache and possibly more efficient power delivery, allows its Zen 5 cores to sustain much higher performance under load.
In multi-core workloads, the Threadripper’s advantage is equally pronounced. Cinebench R23 multi-core shows a score of 130,529 versus 18,698, a delta of -85.7%. Cinebench R15 multi-core follows a similar pattern: 13,157 versus 2,842, a delta of -78.4%. PassMark integer math shows 872,071 versus 101,831, a delta of -88.3%. PassMark floating point math shows 559,003 versus 62,802, a delta of -88.8%. These figures confirm that the Threadripper’s 64 cores provide an overwhelming advantage in any workload that can utilize them.
The smallest margin is in PassMark single-thread, where the Threadripper scores 4,537 versus 3,841, a delta of -15.3%. This is the only test where the AI 9 365 comes within a reasonable distance. In PassMark physics, the Threadripper scores 8,001 versus 1,704, a delta of -78.7%. PassMark data compression shows 2,974,534 versus 354,510, a delta of -88.1%.

The Verdict
The data points to an obvious split. The AMD Ryzen Threadripper 9980X is the superior processor for any multi-threaded, compute-intensive workload. Its 64 cores, 128 threads, 256 MB of L3 cache, and 204.8 GB/s of memory bandwidth make it the clear choice for rendering, simulation, data analysis, and any professional application that scales with core count. Its 99th percentile ranking among all CPUs, against the AI 9 365’s 87th, reinforces its position at the top of the performance hierarchy.
The AMD Ryzen AI 9 365, while losing every benchmark, is not without purpose. Its 28-watt TDP and integrated Radeon 880M graphics make it suitable for mobile devices where power efficiency and portability are paramount. Its 10-core, 20-thread configuration, combined with a 5.00 GHz boost clock, delivers respectable single-thread performance, as shown by its 3,841 PassMark single-thread score, which is only 15.3% behind the Threadripper. For users who need a capable processor for everyday tasks, light content creation, or on-the-go productivity, the AI 9 365 serves a role the Threadripper cannot: it operates within a 28-watt envelope.
The Threadripper 9980X, with its 350-watt TDP, is not designed for such environments. It requires a desktop socket, external cooling, and a power supply capable of sustaining its demands. The recorded data shows no scenario where the AI 9 365 wins, so the choice between these two comes down to the user’s hardware constraints. If the workload is multi-threaded and the system can accommodate a high-power desktop processor, the Threadripper 9980X is the only logical option. If the need is for a low-power mobile chip with integrated graphics, the AI 9 365 is the only viable choice. The benchmarks confirm this binary division with no overlap.
