AMD Ryzen AI Embedded P164i vs AMD Ryzen Threadripper 9980X Comparison

Head-to-Head Benchmarks

The recorded data provides a clear picture of the performance separation between these two processors. The AMD Ryzen AI Embedded P164i has no benchmark scores in the database, resulting in zero wins across all head-to-head comparisons. The AMD Ryzen Threadripper 9980X, by contrast, carries an extensive suite of benchmark results and wins every recorded comparison.

The Threadripper 9980X delivers a Cinebench R15 multi-core score of 13157 and a single-core score of 1857. In Cinebench R20, the multi-core result reaches 54822, with single-core at 7739. The R23 tests show a multi-core score of 130529 and a single-core score of 18427. These numbers place the Threadripper firmly in the high-performance desktop segment.

The Passmark suite further confirms the Threadripper's dominance. The data compression score is 2974534, data encryption reaches 157137, and extended instructions score 228959. Prime number finding scores 769, floating point math hits 559003, and integer math reaches 872071. The multithread score is 141641, physics scores 8001, and random string sorting finishes at 292083. Single-thread performance is recorded at 4537.

Since the P164i lacks any recorded benchmark scores, its average benchmark score is 0, and its percentile versus all CPUs sits at 50. The Threadripper 9980X holds an average benchmark score of 321753 and ranks in the 99th percentile.

Architecture Differences

The two processors share a manufacturing foundation but diverge sharply in design goals. Both use a 4 nm process node from TSMC. The P164i carries the codename Gorgon Point and belongs to the Ryzen AI Embedded generation, which the database records as Zen 5 / Zen 5c. The Threadripper 9980X uses the codename Shimada Peak, belongs to the 9000 series, and is built on Zen 5 architecture.

The die designs reflect the different target markets. The Threadripper 9980X uses a multi-chiplet layout described as 8x 70.6 mm², with a transistor count of 66,520 million. The P164i has a die size of 233 mm². The Threadripper's chiplet approach enables its massive 64-core configuration, while the P164i's monolithic-style design fits an 8-core part.

Cache hierarchies differ substantially. The P164i provides 80 KB of L1 cache per core and 1 MB of L2 cache per core, matching the Threadripper's 1 MB per core L2 but with a smaller L1 allocation. The Threadripper 9980X has 64 KB of L1 per core and a total L3 cache of 256 MB. The P164i's L3 cache is 8 MB. The 32-fold difference in L3 capacity directly supports the Threadripper's high-throughput workload orientation.

Memory support also separates the two. The P164i supports DDR5 and LPDDR5X, while the Threadripper supports DDR5 only. The memory bus widths follow the platform: dual-channel for the P164i versus quad-channel for the Threadripper. PCIe connectivity differs as well, with the P164i offering Gen 4 with 16 lanes (CPU only) and the Threadripper providing Gen 5 with 80 lanes (CPU only). The Threadripper also has an unlocked multiplier, whereas the P164i does not.

The P164i integrates a Radeon 880M GPU, making it suitable for systems without a discrete graphics card. The Threadripper 9980X has no integrated graphics, reflecting its intended use with dedicated GPUs. Socket choices follow these platform differences: the P164i uses AMD Socket FP8, and the Threadripper 9980X uses AMD Socket sTR5.

The Verdict

The data indicates two entirely different product categories. The AMD Ryzen AI Embedded P164i is a mobile-market processor with a 28 W TDP, 8 cores, and integrated Radeon 880M graphics. Its release date is recorded as March 8, 2026, and it has no launch MSRP in the database. The AMD Ryzen Threadripper 9980X is a desktop-market processor with a 350 W TDP, 64 cores, and no integrated graphics. It was released on July 29, 2025, with a launch MSRP of $4999.

For workloads that scale with core count and memory bandwidth, the Threadripper 9980X is the only option with recorded performance data. Its 99th percentile ranking and average benchmark score of 321753 place it among the fastest CPUs in the database. The P164i sits at the 50th percentile with no benchmark scores, meaning no quantitative performance claims can be made for it.

The P164i's advantages are qualitative: lower power draw, integrated graphics, and support for LPDDR5X memory. These features suit embedded and mobile applications where space and thermal limits matter. The Threadripper 9980X's advantages are quantitative and substantial: 8 times the cores, 8 times the threads, 32 times the L3 cache, more than double the memory bandwidth, and 5 times the PCIe lanes at a newer generation.

The choice depends on the workload. For compute-heavy rendering, data processing, or multi-threaded applications, the Threadripper 9980X is the clear selection based on its benchmark scores. For power-constrained embedded systems requiring integrated graphics, the P164i is the only one of the two that fits those requirements.

Specification Differences

The two processors differ on nearly every specification field. The P164i has 8 cores and 16 threads, while the Threadripper 9980X has 64 cores and 128 threads. Base clocks are 2.00 GHz for the P164i and 3.20 GHz for the Threadripper. Boost clocks are 5.00 GHz and 5.40 GHz, respectively.

TDP ratings diverge widely: 28 W for the P164i versus 350 W for the Threadripper. The P164i uses AMD Socket FP8, while the Threadripper uses AMD Socket sTR5. The Threadripper belongs to the 9000 series and uses Zen 5 architecture, while the P164i's architecture is recorded as null but its generation is listed as Ryzen AI Embedded (Zen 5 / Zen 5c). Codename differences are Gorgon Point versus Shimada Peak.

Process node and foundry are identical at 4 nm and TSMC. Transistor counts differ, with the Threadripper at 66,520 million and the P164i at null. Die size is 233 mm² for the P164i versus 8x 70.6 mm² for the Threadripper. L1 cache is 80 KB per core versus 64 KB per core. L2 cache matches at 1 MB per core. L3 cache is 8 MB versus 256 MB.

Memory support shows the P164i accepting DDR5 and LPDDR5X, while the Threadripper accepts DDR5 only. Memory bus is dual-channel versus quad-channel. Memory bandwidth is 89.6 GB/s versus 204.8 GB/s. PCIe is Gen 4 with 16 lanes versus Gen 5 with 80 lanes. Integrated graphics are Radeon 880M versus N/A. Market segment is Mobile versus Desktop. Release dates are March 8, 2026, versus July 29, 2025. Launch MSRP is null versus $4999. The multiplier is locked on the P164i and unlocked on the Threadripper.

Where Each One Wins

The Threadripper 9980X wins every recorded benchmark category. Its Cinebench scores across R15, R20, and R23 in both single and multi-core tests show strong performance, with the multi-core R23 result at 130529. The Passmark suite covers data compression, encryption, extended instructions, prime numbers, floating point math, integer math, multithread, physics, random string sorting, and single-thread tests. The Threadripper's 99th percentile ranking confirms its position at the top of the database.

The P164i wins no recorded benchmarks, but its specification profile gives it qualitative advantages. The 28 W TDP allows deployment in thermally constrained environments where the Threadripper's 350 W TDP would be impractical. The integrated Radeon 880M GPU eliminates the need for a discrete graphics card in embedded systems. Support for LPDDR5X memory enables lower-power memory configurations. The smaller die size of 233 mm² and lower lane count of 16 PCIe Gen 4 lanes indicate a more compact platform footprint.

The memory bandwidth difference favors the Threadripper for memory-intensive tasks: 204.8 GB/s versus 89.6 GB/s. The quad-channel bus provides 4 times the memory channels of the P164i's dual-channel setup. L3 cache capacity favors the Threadripper by a factor of 32, which benefits workloads with large working sets. The 80 PCIe Gen 5 lanes support extensive I/O configurations, including multiple GPUs and high-speed storage arrays.

For single-threaded tasks, the Threadripper's higher boost clock of 5.40 GHz gives it an edge over the P164i's 5.00 GHz, though the P164i's 8 cores still provide reasonable multi-threading capability for lighter loads. The Threadripper's unlocked multiplier allows overclocking, a feature absent on the P164i.

In summary, the Threadripper 9980X dominates in compute performance, memory throughput, cache capacity, and I/O expandability. The P164i offers efficiency, integrated graphics, and mobile-platform compatibility. The recorded data supports the Threadripper for any performance-critical application, while the P164i serves embedded use cases where its unique features matter.
