AMD Ryzen AI Embedded P185 vs AMD Ryzen Threadripper 9960X Comparison

Head-to-Head Benchmarks

The AMD Ryzen AI Embedded P185 and the AMD Ryzen Threadripper 9960X occupy different tiers of AMD’s product stack, and the recorded benchmark data reflects that divide. The P185 has a full set of PassMark measurements available, while the Threadripper 9960X shows no recorded benchmark scores in the database. That absence means the head-to-head comparison is one-sided: the P185 can be measured against its own nearest rivals, but the Threadripper 9960X has no direct benchmark entries to place beside it.

The P185 delivers a single-thread score of 3977, which places it in the 93rd percentile among all CPUs in the database. That is a strong result for a 12-core mobile part. Its nearest rival, the Intel Core Ultra 7 255HX, averages 62738 across all benchmark categories, and the P185’s average benchmark score of 62839 puts it 0.2% ahead of that Intel part. The gap is narrow, but it indicates the P185 is competitive with top-tier mobile HX-series processors in aggregate performance.

In multi-threaded work, the P185 scores 31817 on PassMark’s multithread test. Its nearest rivals sit within a tight band: the Intel Core i7-13790F averages 63080, which is 0.4% higher than the P185’s average, and the Intel Core Ultra 7 265HX averages 63173, 0.5% higher. The AMD Ryzen AI 9 PRO 465 trails the P185 by 0.5% with an average of 62498. These deltas are small, and they show the P185 holding its own against both desktop and mobile competition in the same performance envelope.

The P185’s integer math score of 117832 and floating-point math score of 70587 are substantial for a 28-watt part. Its extended instructions score of 26544 and data encryption score of 19612 further indicate strong throughput in cryptography and SIMD workloads. The data compression score of 374429 is the highest single result recorded for the P185, suggesting that compression workloads benefit heavily from the processor’s cache hierarchy and core configuration.

The Threadripper 9960X, by contrast, has no recorded benchmarks and no nearest rivals in the database. Its percentile rank of 50 is a default value rather than a measured position, and its average benchmark score of 0 reflects the missing data. Without measurements, the database cannot confirm how the 24-core, 48-thread Threadripper compares to the P185 in any specific workload. The specification sheet implies a large performance advantage for the Threadripper in multi-threaded tasks, but the absence of benchmark scores means that advantage is not quantified in the recorded data.

Where Each One Wins

The P185 wins in every category where benchmark data exists, simply because it is the only one of the two with recorded scores. Its single-thread result of 3977 and multithread result of 31817 give it a measurable profile across both lightly threaded and heavily threaded applications. The physics score of 1772 and the prime number finding score of 129 are lower in absolute terms, but they are still recorded results, which is more than the Threadripper 9960X can claim in this database.

The Threadripper 9960X wins on paper in terms of core count, thread count, clock speeds, and memory bandwidth. It has 24 cores and 48 threads, double the P185’s 12 cores and 24 threads. Its base clock of 4.20 GHz and boost clock of 5.30 GHz both exceed the P185’s 2.00 GHz base and 5.10 GHz boost. Its quad-channel DDR5 memory bus delivers 204.8 GB/s of bandwidth, versus the P185’s dual-channel 89.6 GB/s. These are structural advantages that would likely translate into large wins in rendering, compilation, and scientific computing, but the database has no scores to confirm it.

The P185 is designed for mobile and embedded systems, as its market segment indicates. Its 28-watt TDP and integrated Radeon 890M graphics make it suitable for compact, power-constrained platforms. The Threadripper 9960X is a desktop part with a 350-watt TDP and no integrated graphics, aimed at workstation builds where power draw is less of a concern. The recorded data supports the P185 as a measured performer in its class; the Threadripper remains an unmeasured entity whose advantages are purely specification-based.

Architecture Differences

Both processors use TSMC’s 4 nm process node, which is a shared foundation. The internal architecture, however, diverges significantly. The P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation with a mix of Zen 5 and Zen 5c cores. The Threadripper 9960X uses the Shimada Peak codename and is built entirely on Zen 5 architecture, part of the Ryzen Threadripper 9000 series.

The P185’s hybrid core design combines full Zen 5 cores with denser Zen 5c cores, which is a common approach for mobile parts that need to balance performance and efficiency. The Threadripper 9960X uses only full Zen 5 cores, which are larger but offer consistent performance across all cores. The die size reflects this difference: the P185 has a single 233 mm² die, while the Threadripper 9960X uses four 70.6 mm² dies, totaling roughly 282.4 mm² of silicon. The Threadripper also lists 33,260 million transistors, a figure the P185 does not have recorded.

Cache hierarchies differ as well. The P185 has 80 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Threadripper 9960X has 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Threadripper’s L3 cache is eight times larger, which is a substantial advantage for workloads with large working sets. The per-core L1 difference is reversed, with the P185 offering more L1 per core, but the Threadripper’s larger L3 is the more impactful difference for multi-threaded server-style workloads.

PCIe support also separates the two. The P185 uses PCIe Gen 4 with 16 lanes, while the Threadripper 9960X uses PCIe Gen 5 with 80 lanes. That is a fivefold increase in lane count and a generational jump in bandwidth, which matters for multi-GPU configurations and high-speed storage arrays. Both support ECC memory, but the P185 supports both DDR5 and LPDDR5X, while the Threadripper supports only DDR5.

Specification Differences

The most obvious difference is core count. The P185 has 12 cores and 24 threads; the Threadripper 9960X has 24 cores and 48 threads. Base clocks are 2.00 GHz versus 4.20 GHz, and boost clocks are 5.10 GHz versus 5.30 GHz. The Threadripper runs at a higher frequency at both ends of the clock range.

Thermal design power is another major split. The P185 is rated at 28 watts, while the Threadripper 9960X is rated at 350 watts. That is a 12.5x difference in thermal envelope, which explains the Threadripper’s higher clock speeds and larger core count. The sockets are incompatible: the P185 uses AMD Socket FP8, and the Threadripper 9960X uses AMD Socket sTR5.

Memory support differs in channel count and bandwidth. The P185 has a dual-channel memory bus with 89.6 GB/s of bandwidth, while the Threadripper 9960X has a quad-channel bus with 204.8 GB/s. The P185 supports DDR5 and LPDDR5X memory; the Threadripper supports DDR5 only. Both support ECC memory, which is notable for embedded and workstation reliability.

Integrated graphics are present on the P185 as Radeon 890M, while the Threadripper 9960X has no integrated graphics. The P185 is a mobile-market part, and the Threadripper is a desktop-market part. The Threadripper has an unlocked multiplier, allowing overclocking, while the P185 does not. The Threadripper’s launch MSRP is $1499, a figure the database records once; the P185 has no launch MSRP listed. The Threadripper’s part number is 100-000001595, while the P185’s part number is unknown.

Release dates also differ. The Threadripper 9960X was released on 2025-07-29, and the P185 was released on 2026-02-28. Both are listed as active in production status.
