AMD Ryzen AI Embedded P185i vs AMD Ryzen Threadripper 9970X Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark scores for the AMD Ryzen AI Embedded P185i, which limits direct numerical comparison. However, the AMD Ryzen Threadripper 9970X has a comprehensive set of PassMark results that establish its performance tier. The Threadripper 9970X achieves an average benchmark score of 279,778, placing it in the 99th percentile of all CPUs in the database. Its nearest rivals include the Intel Xeon 6780E at 280,438 (0.2% higher), the AMD EPYC 9565 at 285,471 (2% higher), the Intel Xeon 696X at 286,102 (2.2% higher), and the AMD EPYC 9555P at 287,066 (2.5% higher). This indicates the Threadripper 9970X sits within a tight competitive band, trailing the fastest enterprise chips by only a small margin.

The Threadripper 9970X's individual PassMark results show its character. The single-thread score is 4,530, which is strong for a 32-core part. The multithread score of 107,399 reflects massive parallel throughput. Integer math scores 465,378, floating point math scores 309,719, and extended instructions score 142,342. Data compression reaches 1,757,998, while data encryption hits 86,765. Random string sorting posts 191,445, and the find prime numbers test returns 615. Physics processing scores 6,835.

For the Ryzen AI Embedded P185i, the database lists an average benchmark score of 0 and a percentile of 50, meaning it falls in the middle of the distribution based on available data. This is not a reflection of real-world capability, but rather an artifact of missing benchmark entries. The P185i is a 12-core, 24-thread mobile part with a boost clock of 5.10 GHz, which suggests it would compete in a different performance class entirely, likely far below the Threadripper's 32-core, 64-thread configuration.

The data confirms that the Threadripper 9970X is a top-tier workstation processor, while the P185i's absence of benchmark scores means no head-to-head victory can be assigned numerically. The wins counter in the database shows zero wins for each part, which is consistent with the lack of matched test data.

Architecture Differences

The two processors come from different AMD product families. The Ryzen AI Embedded P185i uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. The Ryzen Threadripper 9970X uses the Shimada Peak codename and is part of the Ryzen Threadripper generation built on Zen 5 architecture. Both are manufactured on a 4 nm process at TSMC, so the underlying transistor technology is identical.

The die configurations differ significantly. The P185i uses a single 233 mm² die, while the Threadripper 9970X uses four dies of 70.6 mm² each, totaling roughly 282 mm² of silicon. The Threadripper packs 33,260 million transistors, while the P185i's transistor count is not recorded in the database.

Core counts establish the first major architectural split. The P185i has 12 cores and 24 threads, while the Threadripper 9970X has 32 cores and 64 threads, a 2.67x increase in core count and a 2.67x increase in thread count. Cache hierarchies also diverge. The P185i provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 total. The Threadripper 9970X provides 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 total. The Threadripper's L3 is 8x larger, which matters for workloads with large working sets.

Clock speeds reveal the P185i's efficiency-oriented design. It has a 2.00 GHz base clock and a 5.10 GHz boost clock. The Threadripper 9970X has a 4.00 GHz base clock and a 5.40 GHz boost clock. The Threadripper's base clock is double that of the P185i, which is a direct consequence of the much higher power envelope.

Memory subsystems also differ substantially. The P185i supports DDR5 and LPDDR5X memory on a dual-channel bus, delivering 89.6 GB/s of bandwidth. The Threadripper 9970X supports DDR5 on a quad-channel bus, delivering 204.8 GB/s, a 2.29x bandwidth advantage. Both support ECC memory.

PCIe connectivity is a major differentiator. The P185i provides Gen 4 with 16 lanes from the CPU. The Threadripper 9970X provides Gen 5 with 80 lanes from the CPU. That is 5x the lane count and a full generation newer. The P185i includes integrated Radeon 890M graphics, while the Threadripper 9970X has no integrated graphics at all.

Where Each One Wins

The Ryzen Threadripper 9970X wins in every scenario where raw compute throughput matters. Its 32 cores and 64 threads, combined with 128 MB of L3 cache and 204.8 GB/s of memory bandwidth, make it the clear choice for multithreaded workloads such as rendering, simulation, video encoding, and large data analysis. The benchmark scores confirm this: the multithread score of 107,399 and the data compression score of 1,757,998 are extremely high. The 99th percentile ranking places it among the fastest consumer-adjacent processors available. Its quad-channel memory and 80 PCIe Gen 5 lanes support heavy I/O configurations with multiple GPUs or NVMe storage arrays.

The Ryzen AI Embedded P185i wins where power efficiency and integration matter. Its 28 W TDP is dramatically lower than the Threadripper's 350 W TDP, and it integrates Radeon 890M graphics, eliminating the need for a discrete GPU in many embedded or mobile applications. The dual-channel memory and Gen 4 PCIe are sufficient for its intended market. The 5.10 GHz boost clock shows strong single-thread potential for a low-power part, which suits responsive interactive workloads. Its 12 cores and 24 threads still provide meaningful parallelism, and the 16 MB L3 cache is adequate for embedded workloads.

The Threadripper 9970X is the choice for a dedicated workstation or server that runs sustained, heavily threaded jobs. The P185i is the choice for a compact embedded system or mobile workstation where physical space, power draw, and integrated graphics are priorities. The data does not support any conclusion about the P185i's absolute performance, but the architectural differences make the use-case split clear.

The Verdict

The data makes the choice straightforward. The AMD Ryzen Threadripper 9970X is a high-core-count workstation part with verified benchmark results in the 99th percentile. Its 32 cores, 64 threads, 128 MB of L3 cache, quad-channel memory delivering 204.8 GB/s, and 80 PCIe Gen 5 lanes position it for heavy parallel workloads. The recorded scores show strong multithread performance, and its closest rivals are within a narrow 2.5% band, confirming it is a competitive top-tier processor. Its 350 W TDP and lack of integrated graphics mean it is meant for a full-size workstation with dedicated cooling and a discrete GPU.

The AMD Ryzen AI Embedded P185i is a different class of product. It has 12 cores, 24 threads, a 28 W TDP, and integrated Radeon 890M graphics. Its 5.10 GHz boost clock is respectable, and its 16 MB L3 cache is adequate for its target workloads. It supports both DDR5 and LPDDR5X, which adds flexibility for embedded designs. The lack of benchmark scores in the database prevents a numerical performance assessment, but the architecture points to a mobile or embedded efficiency-focused part.

Who should pick which: choose the Threadripper 9970X for a desktop workstation that runs rendering, simulation, or data processing tasks that scale across many cores. Choose the P185i for an embedded or mobile system where power draw, physical size, and integrated graphics are critical constraints. The Threadripper 9970X's launch MSRP is $2499, which places it clearly in the professional workstation tier. The P185i has no recorded MSRP, but its specifications indicate a more power-conscious design. The decision rests on whether the workload demands maximum parallel throughput or maximum efficiency in a compact form factor.
