Architecture Differences

The two processors come from different segments of AMD's lineup, and their architectural choices reflect that divergence. The Ryzen AI Embedded P185i is a mobile part built on the Gorgon Point codename. Its generation is listed as Ryzen AI Embedded, with a combination of Zen 5 and Zen 5c cores. The die size is 233 mm². In contrast, the Ryzen Threadripper 9980X is a desktop processor belonging to the 9000 series, uses the Zen 5 architecture, and carries the codename Shimada Peak. Its physical implementation is a multi-chiplet design, with 8 dies each measuring 70.6 mm², totaling 66,520 million transistors.

Both processors are manufactured by TSMC on a 4 nm process node. The per-core cache structure differs. The Ryzen AI Embedded P185i has 80 KB of L1 cache per core and 1 MB of L2 cache per core. The Ryzen Threadripper 9980X has 64 KB of L1 cache per core and 1 MB of L2 cache per core. The L3 cache is the most dramatic divergence: the embedded part has 16 MB, while the Threadripper part has 256 MB.

Memory support also separates the two. The Ryzen AI Embedded P185i supports both DDR5 and LPDDR5X memory, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Ryzen Threadripper 9980X supports DDR5 only, but its quad-channel bus delivers a memory bandwidth of 204.8 GB/s. The embedded processor includes integrated Radeon 890M graphics, while the Threadripper part has no integrated graphics. PCIe connectivity is another major split: the P185i uses Gen 4 with 16 lanes (CPU only), and the 9980X uses Gen 5 with 80 lanes (CPU only). The embedded chip is not multiplier unlocked, while the Threadripper part is multiplier unlocked.

Head-to-Head Benchmarks

The recorded data includes benchmark results for the Ryzen Threadripper 9980X, but no benchmark scores are available for the Ryzen AI Embedded P185i.

The Verdict

The recorded data tells a clear story of two processors built for different workloads. The Ryzen Threadripper 9980X is a high-core-count desktop processor with 64 cores and 128 threads, a 5.40 GHz boost clock, 256 MB of L3 cache, and a 350 watt TDP. It sits at the 99th percentile versus all CPUs, with an average benchmark score of 321,753. Its benchmark results show strong multicore performance across Cinebench and PassMark tests. The Ryzen AI Embedded P185i is a mobile processor with 12 cores and 24 threads, a 5.10 GHz boost clock, 16 MB of L3 cache, and a 28 watt TDP. It has no recorded benchmark scores, so its measured performance cannot be compared directly.

The absence of benchmark data for the P185i means the database cannot confirm any performance relationship between the two. The wins count is 0 for both processors in the head-to-head section. What can be stated from the data is that the Threadripper 9980X has a strong recorded performance profile and leads its nearest rivals by margins between 0.3% and 3.6%. The embedded part, with its much lower TDP and mobile segment classification, is positioned for power-constrained applications, while the Threadripper part is positioned for high-throughput desktop workloads.

For a user choosing based on the database alone, the Threadripper 9980X is the only one of the two with measured scores, and it demonstrates very high performance. The P185i offers integrated graphics and lower power draw, but its performance level is unquantified in the database. The choice depends on whether the workload requires the massive core count and cache of the Threadripper part or the mobile form factor and integrated graphics of the embedded part.

Where Each One Wins

The Ryzen Threadripper 9980X wins in every measured category, simply because it is the only one of the two with recorded benchmark data. Its Cinebench R23 multicore score of 130,529 and PassMark multithread score of 141,641 indicate strong performance in heavily threaded workloads. Its 256 MB L3 cache and 204.8 GB/s memory bandwidth support data-intensive tasks. Its 80 Gen 5 PCIe lanes provide extensive expansion capability. The 9980X also holds a narrow lead over its nearest rivals, with the closest competitor, the Ryzen Threadripper PRO 9985WX, trailing by 0.3%.

The Ryzen AI Embedded P185i wins in areas unrelated to measured performance. Its 28 watt TDP is dramatically lower than the 350 watt TDP of the Threadripper part, indicating a much smaller power envelope. It includes integrated Radeon 890M graphics, which the Threadripper lacks. It supports LPDDR5X memory in addition to DDR5, while the Threadripper supports DDR5 only. Its mobile market segment and AMD Socket FP8 indicate a compact physical footprint. These features position it for embedded and mobile applications where power efficiency and integrated graphics matter more than raw compute throughput.

The data does not support any claim of a performance win for the P185i, as no benchmark scores exist for it. The Threadripper 9980X has the performance records, the higher percentile ranking, and the superior specification sheet for compute-heavy workloads. The embedded part has the efficiency and integration advantages, but those are not quantified in the database. Each processor wins in its own domain: the 9980X in measured performance, the P185i in power and integration features.
