AMD Ryzen AI Embedded P164i vs AMD Ryzen Threadripper 9960X Comparison

The AMD Ryzen AI Embedded P164i and AMD Ryzen Threadripper 9960X occupy different corners of AMD's 4 nm lineup. The database records no head-to-head benchmark scores for this pair: the average benchmark score for both entries is 0, the win count is 0 for each, and both sit at the 50th percentile against all CPUs. The recorded data therefore supports a specification-based comparison, not a measured-performance comparison.

Where Each One Wins

Because the recorded benchmark wins are 0 for both processors, the use-case split must be read from the specification data. The P164i is the part that wins on integration and power. It uses AMD Socket FP8, is classified as a mobile part, and carries a Radeon 880M integrated GPU. Its TDP is 28, compared with 350 for the Threadripper. It supports DDR5 and LPDDR5X over a dual-channel interface with 89.6 GB/s of memory bandwidth. For embedded systems that need a low-power CPU with graphics on the package, those are the decisive fields.

The Threadripper 9960X wins on compute scale and platform bandwidth. It provides 24 cores and 48 threads, a 128 MB L3 cache, quad-channel DDR5 memory at 204.8 GB/s, and PCIe Gen 5 with 80 lanes. It is a desktop part on Socket sTR5, with an unlocked multiplier. Its base clock is 4.20 GHz and boost clock is 5.30 GHz. The P164i counters with a 2.00 GHz base and 5.00 GHz boost, but the core count difference is too large for clocks to close. The data gives the P164i the embedded/mobile niche and gives the Threadripper the high-throughput desktop niche.

Architecture Differences

Both processors are built on TSMC's 4 nm node, so the manufacturing process is not a differentiator. The codenames are different: Gorgon Point for the P164i and Shimada Peak for the Threadripper 9960X. The generation strings also differ: Ryzen AI Embedded (Zen 5 / Zen 5c) for the P164i, Ryzen Threadripper (Zen 5 (Shimada Peak)) for the Threadripper. The architecture field is left blank for the P164i and lists Zen 5 for the Threadripper.

The cache layout separates the two. The P164i uses 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of L3. The Threadripper uses 64 KB of L1 per core and 1 MB of L2 per core, with 128 MB of L3. Both share the same per-core L2 allocation, but the Threadripper's L3 is far larger. The die information also differs: the P164i lists a 233 mm² die, while the Threadripper lists 4x 70.6 mm². The Threadripper's transistor count is recorded as 33,260 million; the database does not list a transistor count for the P164i.

The memory controllers differ as well. The P164i supports DDR5 and LPDDR5X on a dual-channel bus. The Threadripper supports DDR5 on a quad-channel bus. Bandwidth follows: 89.6 GB/s for the P164i, 204.8 GB/s for the Threadripper. Both support ECC memory. The P164i provides PCIe Gen 4 with 16 lanes, while the Threadripper provides PCIe Gen 5 with 80 lanes. The Threadripper has no integrated graphics; the P164i has a Radeon 880M. The Threadripper is unlocked, while the P164i multiplier is not.

Head-to-Head Benchmarks

The database has no recorded benchmark scores for either processor. The win counters are 0 for both sides, and the average benchmark score is 0 for both. As a result, the largest recorded differences are specification deltas rather than measured performance deltas.

The Threadripper 9960X holds the biggest advantages in the fields that drive multi-threaded throughput. It has 24 cores and 48 threads against 8 cores and 16 threads for the P164i. Its L3 cache is 128 MB against 8 MB. Its base clock is 4.20 GHz against 2.00 GHz, and its boost clock is 5.30 GHz against 5.00 GHz. Its memory bandwidth is 204.8 GB/s against 89.6 GB/s. Its PCIe interface is Gen 5 with 80 lanes against Gen 4 with 16 lanes. These are large gaps in core count, cache, memory bandwidth, and expansion capacity.

The P164i holds its advantages in power and integration. Its TDP is 28 against 350. It lists a Radeon 880M integrated GPU, while the Threadripper lists N/A. It supports LPDDR5X in addition to DDR5, which fits a mobile/embedded memory environment. Its L1 cache per core is 80 KB against 64 KB, so it has a small per-core cache edge. Its boost clock of 5.00 GHz sits close to the Threadripper's 5.30 GHz.

The Verdict

The recorded data points in one direction for each processor. The Threadripper 9960X is the part for desktop workloads that scale with cores, threads, cache, and memory bandwidth. It offers 24 cores, 48 threads, 128 MB L3, quad-channel 204.8 GB/s memory, and 80 PCIe Gen 5 lanes, all in a 350 W desktop package on Socket sTR5 with an unlocked multiplier. The P164i is the part for embedded or mobile systems where power draw, physical integration, and onboard graphics matter. It offers 8 cores, 16 threads, a 28 W TDP, a Radeon 880M, and DDR5/LPDDR5X support on a dual-channel bus.

There is no benchmark score in the database to overturn those specification-based conclusions. The P164i is not a substitute for the Threadripper in high-core-count workloads, and the Threadripper is not a substitute for the P164i in a low-power embedded design. The choice follows the platform: mobile/embedded with integrated graphics versus desktop with maximum core, cache, and memory resources.
