Head-to-Head Benchmarks

The biggest win for the AMD Ryzen AI 7 450G comes in single-thread performance. It scores 4309, which is 8.3% higher than the P185’s 3977. This is a decisive margin for tasks that depend on clock speed and instruction efficiency. The 450G also shows a strong 7.6% lead in data compression, scoring 402831 versus 374429. This suggests the 450G’s memory subsystem and core design are better optimized for streaming data patterns that are not fully parallelizable.

The AMD Ryzen AI Embedded P185 counters with its most striking victory in prime number finding, where it scores 129 versus the 450G’s 87, a 32.6% gap. This is likely a direct result of the P185’s higher core count and larger L3 cache. The P185 also dominates physics calculations, winning by 18.7% (1772 vs 1440). In integer math, the P185’s 117832 is 15.4% ahead of the 450G’s 99732, and in floating-point math it leads by 9.8% (70587 vs 63683). The multithread score of 31817 for the P185 is 4.4% higher than the 450G’s 30422.

The remaining tests are closer. The 450G wins extended instructions by 6.3% (28223 vs 26544) and random string sorting by 5.2% (42663 vs 40557). The P185 wins data encryption by 3.4% (19612 vs 18937). While the P185 takes more total wins, the 450G’s margins in single-thread and compression are larger than the P185’s margins in most of its victories, except for prime numbers and physics. This creates a profile where the 450G excels in latency-sensitive tasks, while the P185 excels in throughput-heavy tasks.

Specification Differences

The core difference is the core count: the AMD Ryzen AI 7 450G has 8 cores and 16 threads, while the AMD Ryzen AI Embedded P185 has 12 cores and 24 threads. Both have a 2.00 GHz base clock and a 5.10 GHz boost clock. The P185 has double the L3 cache (16 MB vs 8 MB). The TDP is dramatically different, with the 450G rated at 65W and the P185 at 28W, indicating the P185 is designed for more power-constrained environments.

The sockets are incompatible: the 450G uses AMD Socket AM5, while the P185 uses AMD Socket FP8. The 450G is classified as a desktop part, while the P185 is a mobile part. The 450G has an unlocked multiplier for overclocking, while the P185 is locked. The integrated graphics differ as well: the 450G features the Radeon 860M, while the P185 features the Radeon 890M. The PCIe configuration also differs, with the P185 offering 16 Gen 4 lanes (CPU only) compared to the 450G’s 12 Gen 4 lanes. Both share the same die size differences (195 mm² vs 233 mm²) and are produced on the same 4 nm process.

Architecture Differences

Both chips share the same "Gorgon Point" codename and are built on a hybrid Zen 5 / Zen 5c architecture, per the generation field. They are both manufactured by TSMC on a 4 nm process. The core architecture is identical per-core, with 80 KB of L1 and 1 MB of L2 cache per core. The key architectural difference is the L3 cache pool: the 450G has 8 MB, while the P185 has 16 MB. This larger shared cache on the P185 likely contributes to its superior performance in physics and integer math, where working sets can exceed the 450G’s smaller cache.

The P185’s larger die size (233 mm² vs 195 mm²) reflects the additional two cores and 8 MB of L3 cache. Both chips support the same DDR5 and LPDDR5X memory standards with dual-channel access and identical 89.6 GB/s bandwidth. The P185 is built for a mobile socket (FP8) and is not overclockable, while the 450G is a desktop part on AM5 with an unlocked multiplier. The integrated GPU also differs, with the P185 using the Radeon 890M and the 450G using the Radeon 860M, suggesting different graphics performance tiers.

The Verdict

The data points to a clear split. The AMD Ryzen AI 7 450G is the better choice for users who prioritize single-threaded performance and low-latency workloads. Its 8.3% lead in single-thread score, 7.6% lead in data compression, and 6.3% lead in extended instructions make it ideal for everyday desktop use, application responsiveness, and tasks that are not heavily parallelized. Its unlocked multiplier also appeals to enthusiasts who want to push performance further.

The AMD Ryzen AI Embedded P185 is the better choice for multi-threaded and compute-heavy workloads. Its 12 cores and 16 MB of L3 cache deliver a 15.4% lead in integer math, a 9.8% lead in floating-point math, and an 18.7% lead in physics. For rendering, scientific computation, or any workload that scales across cores, the P185 is the superior processor. Its lower 28W TDP also makes it suitable for embedded or mobile applications where power efficiency is critical, though the 450G’s higher 65W TDP allows for a desktop socket with overclocking.

When the average scores are considered, the 450G’s 63331 average is only 0.8% higher than the P185’s 62839, which is within the margin of error for most real-world applications. The choice is not about which is "better" but which set of strengths matches the user’s needs. The 450G is the desktop performance pick; the P185 is the mobile and embedded multi-core specialist.
