AMD Ryzen AI 7 450 vs AMD Ryzen Embedded 8845HS Comparison

AMD Ryzen AI 7 450 vs AMD Ryzen Embedded 8845HS

The database places the AMD Ryzen AI 7 450 in the 87th percentile of all CPUs, a position driven by its Zen 5 architecture and high boost clock. The AMD Ryzen Embedded 8845HS, built on Zen 4, holds a 50th percentile standing. Both parts share an 8-core, 16-thread configuration and the same 5.10 GHz boost ceiling, but the Ryzen AI 7 450’s newer core design and lower 28 W TDP versus the 8845HS’s 45 W TDP create distinct performance and efficiency profiles.

Where Each One Wins

The AMD Ryzen AI 7 450 is the clear winner in single-threaded and burst workloads, thanks to its Zen 5 cores. In Cinebench R23 single-core, it scores 2038 points, a figure that reflects the architectural advantage of Zen 5 over the older Zen 4 design in the Embedded 8845HS. This advantage carries into less demanding tasks where clock speed and per-core efficiency matter most, such as everyday application responsiveness, light productivity, and any software that relies on a single primary thread.

The AMD Ryzen Embedded 8845HS, lacking recorded benchmark scores in the database, cannot be directly compared on a per-test basis. However, its higher base clock of 3.80 GHz, compared to the Ryzen AI 7 450’s 2.00 GHz, indicates a design tuned for sustained throughput under a higher power envelope. The 8845HS also supports PCIe Gen 4 with 20 lanes (CPU only), versus 16 lanes on the Ryzen AI 7 450, making it the superior choice for embedded applications requiring additional high-speed expansion, such as multiple NVMe drives or specialized accelerator cards.

For multi-threaded workloads, the Ryzen AI 7 450’s Cinebench R23 multi-core score of 18316 points is substantial. The Embedded 8845HS, with its 45 W TDP and 16 MB of shared L3 cache (versus 8 MB on the Ryzen AI 7 450), is positioned for consistent heavy lifting, but the lack of benchmark data prevents a quantitative comparison. The data suggests the Ryzen AI 7 450 is optimized for low-power mobile devices where short bursts of high performance are critical, while the 8845HS targets industrial and embedded systems where sustained operation and expansion capability take priority.

Architecture Differences

The fundamental architectural split is between Zen 5 and Zen 4. The AMD Ryzen AI 7 450 uses Zen 5 cores, a design that delivers higher instructions per clock compared to the Zen 4 cores in the AMD Ryzen Embedded 8845HS. This explains the Ryzen AI 7 450’s superior single-thread scores despite both processors sharing a 5.10 GHz boost clock. The Ryzen AI 7 450 belongs to the Ryzen AI 400 generation (codenamed Gorgon Point), while the 8845HS is part of the Ryzen Embedded 8000 series (codenamed Hawk Point).

Cache hierarchies differ significantly. The Ryzen AI 7 450 allocates 80 KB of L1 cache per core and 1 MB of L2 per core, with 8 MB of shared L3 cache. The Embedded 8845HS uses 64 KB of L1 per core, 1 MB of L2 per core, and doubles the shared L3 cache to 16 MB. The larger L3 on the 8845HS is a notable advantage for workloads that repeatedly access a large working set, potentially mitigating the need for slower main memory accesses.

Both processors are manufactured on TSMC’s 4 nm process, but the die sizes differ: the Ryzen AI 7 450 measures 195 mm², while the Embedded 8845HS is smaller at 178 mm². The 8845HS also has a listed transistor count of 25,000 million, a figure absent for the Ryzen AI 7 450. The smaller die on the 8845HS, combined with its higher TDP, suggests a different power delivery and thermal design, with the 8845HS likely intended for chassis with more robust cooling.

Integrated graphics also diverge. The Ryzen AI 7 450 pairs with a Radeon 860M, while the Embedded 8845HS uses a Radeon 780M. Both are capable of driving displays, but the database records no performance metrics for either iGPU, so any comparative statement on their graphical output is unsupported. Memory support is another differentiator: the Ryzen AI 7 450 accepts both DDR5 and LPDDR5X, whereas the 8845HS is limited to DDR5. Both run dual-channel memory at 89.6 GB/s bandwidth and support ECC memory.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark results between the AMD Ryzen AI 7 450 and the AMD Ryzen Embedded 8845HS, and the 8845HS has no standalone benchmark entries. All comparative analysis must therefore rely on the Ryzen AI 7 450’s recorded scores and the architectural differences between the two parts.

In Cinebench R15, the Ryzen AI 7 450 scores 2713 multi-core and 215 single-core. Its Cinebench R23 results are 18316 multi-core and 2038 single-core. These numbers establish a performance baseline for the Zen 5 part. The PassMark suite shows a single-thread score of 3901, a multi-thread score of 26350, and a physics score of 1578. Integer math scores 88531, floating point math 54447, and extended instructions 22400. Data compression hits 315906, data encryption 16247, random string sorting 35648, and find prime numbers 89.

The Ryzen AI 7 450’s average benchmark score is 39485, placing it within 0.4% of the AMD Ryzen 7 PRO 8845HS (average score 39325) and 0.7% ahead of the AMD EPYC 4245P (average score 39215). It trails the AMD Ryzen 7 9800X3D (average score 39768) by 0.7% and the AMD Ryzen 7 PRO 8840HS (average score 39603) by 0.3%. These deltas are all within one percentage point, indicating that the Ryzen AI 7 450’s overall performance is tightly clustered with several established desktop and mobile parts.

The absence of benchmark data for the Embedded 8845HS means its direct performance cannot be quantified. Its higher base clock and 45 W TDP suggest it can sustain high throughput, but without recorded scores, any numerical comparison is impossible. The Ryzen AI 7 450’s 28 W TDP, by contrast, points to efficient operation, and its Zen 5 cores deliver the highest single-thread scores in the database for this comparison.

Specification Differences

The two processors differ in several key specification fields. The AMD Ryzen AI 7 450 has a base clock of 2.00 GHz, while the AMD Ryzen Embedded 8845HS runs at 3.80 GHz; both boost to 5.10 GHz. TDP is a major split: 28 W for the Ryzen AI 7 450 versus 45 W for the 8845HS. The architecture is Zen 5 for the Ryzen AI 7 450 and Zen 4 for the 8845HS. Their codenames, Gorgon Point and Hawk Point, reflect different generations: Ryzen AI 400 versus Ryzen Embedded 8000.

Cache sizes differ, with the Ryzen AI 7 450 using 80 KB L1 per core and 8 MB L3, while the 8845HS uses 64 KB L1 per core and 16 MB L3. Both share 1 MB L2 per core. The die size is 195 mm² for the Ryzen AI 7 450 and 178 mm² for the 8845HS, with the latter listing 25,000 million transistors. Memory support is broader on the Ryzen AI 7 450, accepting DDR5 and LPDDR5X, versus DDR5 only on the 8845HS. PCIe lane count favors the 8845HS at 20 Gen 4 lanes (CPU only) compared to 16 on the Ryzen AI 7 450. Integrated graphics are Radeon 860M on the Ryzen AI 7 450 and Radeon 780M on the 8845HS.

Both parts use AMD Socket FP8, support dual-channel memory at 89.6 GB/s, have ECC memory support, and are not multiplier-unlocked. The Ryzen AI 7 450 was released on January 4, 2026, while the 8845HS came out on April 1, 2024. Both are active production parts with a mobile market segment. The Ryzen AI 7 450 has a part number of 100-000001868; the 8845HS’s part number is unknown.
