AMD Ryzen AI 7 445 vs AMD Ryzen Embedded 8645HS Comparison

The Verdict

The AMD Ryzen AI 7 445 and the AMD Ryzen Embedded 8645HS are both 6-core, 12-thread processors on the AMD Socket FP8 platform, but they serve fundamentally different purposes. The recorded data shows the Ryzen AI 7 445 is the stronger general-purpose performer, achieving an average benchmark score of 26936 and ranking in the 79th percentile among all CPUs. The Ryzen Embedded 8645HS, by contrast, sits in the 50th percentile with no recorded benchmark scores in the database, placing it in a different performance class entirely.

The Ryzen AI 7 445 targets mobile computing with a 28 W TDP and a hybrid Zen 5 / Zen 5c architecture built on TSMC's 4 nm process. It delivers a boost clock of 4.60 GHz and includes 4 MB of L3 cache. The Ryzen Embedded 8645HS targets embedded applications with a 45 W TDP, a pure Zen 4 architecture also on TSMC's 4 nm process, a higher boost clock of 5.00 GHz, and a much larger 16 MB shared L3 cache. Its higher base clock of 4.30 GHz versus the 445's 2.00 GHz suggests a design optimized for sustained, predictable throughput rather than bursty mobile workloads.

For users choosing between these two, the data indicates the Ryzen AI 7 445 for any scenario where benchmark scores and percentile ranking matter, such as general mobile computing or content creation. The Ryzen Embedded 8645HS, with its higher clocks and larger cache, appears suited for embedded systems where consistent performance and connectivity take precedence over raw benchmark dominance. The 445's benchmark scores are substantial: 10590 in Cinebench R23 multi-core and 1806 in single-core, while the Embedded part has no recorded scores to compare directly.

Architecture Differences

The two processors represent two distinct architectural generations. The AMD Ryzen AI 7 445 uses the Zen 5 architecture under the codename Gorgon Point, belonging to the Ryzen AI 400 generation that combines Zen 5 and Zen 5c cores. This hybrid design allows the processor to balance performance and efficiency within its 28 W TDP envelope. The process node is TSMC's 4 nm process, and the die integrates Radeon 840M graphics.

The AMD Ryzen Embedded 8645HS uses the older Zen 4 architecture under the codename Hawk Point, part of the Ryzen Embedded 8000 series. It also uses TSMC's 4 nm process but features a homogeneous Zen 4 core layout across all 6 cores. The database lists its transistor count at 25,000 million and its die size at 178 mm², figures not provided for the Ryzen AI 7 445. It integrates Radeon 760M graphics.

The cache hierarchies differ notably. The Ryzen AI 7 445 allocates 80 KB of L1 cache per core and 1 MB of L2 per core, but only 4 MB of total L3 cache. The Ryzen Embedded 8645HS allocates 64 KB of L1 per core and 1 MB of L2 per core, but a substantially larger 16 MB of shared L3 cache. This fourfold difference in L3 capacity favors the Embedded part for workloads that benefit from larger working sets residing on-chip.

Both processors share the AMD Socket FP8, support dual-channel memory with 89.6 GB/s bandwidth, and include ECC memory support. The Ryzen AI 7 445 expands memory compatibility to include LPDDR5X in addition to DDR5, while the Embedded 8645HS supports DDR5 only. Neither processor has an unlocked multiplier.

The base clock difference is stark: 2.00 GHz on the Ryzen AI 7 445 versus 4.30 GHz on the Embedded 8645HS. The boost clocks also differ, with the Embedded part reaching 5.00 GHz versus 4.60 GHz on the 445. The TDP gap of 17 W indicates the Embedded part is designed for platforms with more thermal headroom. The Ryzen AI 7 445 has a higher L1 cache per core but a much smaller L3 pool, while the Embedded 8645HS trades per-core L1 capacity for a large shared L3.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen AI 7 445 and the AMD Ryzen Embedded 8645HS. The Embedded part has no recorded benchmark scores, and the head-to-head table is empty. However, the Ryzen AI 7 445's standalone scores provide a reference point for its performance class.

In Cinebench R23, the Ryzen AI 7 445 scores 10590 in multi-core and 1806 in single-core. In Cinebench R15, it scores 1723 multi-core and 254 single-core. PassMark results show a multi-thread score of 18115, a single-thread score of 3591, and a data compression score of 215812. The processor also records 58332 in integer math, 39362 in floating-point math, and 10519 in data encryption. Its extended instructions score is 15826, and it finds 56 prime numbers in the PassMark test.

The Ryzen AI 7 445's average benchmark score of 26936 places it in the 79th percentile of all CPUs. Its nearest rivals in the database include the Intel Core i7-1370P with an average score of 26900 (0.1% ahead), the AMD Ryzen 5 7545U at 26849 (0.3% behind), the AMD Ryzen 7 5700G at 27051 (0.4% behind), and the Intel Core i9-9900K at 27097 (0.6% behind). These narrow deltas indicate the 445 sits in a tightly contested performance band.

Since the Ryzen Embedded 8645HS has no benchmark data, no direct comparison of wins is possible. The database shows zero wins for each processor in the head-to-head section. The available data allows only an indirect assessment: the Embedded part's higher clocks and larger cache suggest it may excel in sustained multi-threaded workloads, but without scores, this remains speculative.

Where Each One Wins

The AMD Ryzen AI 7 445 wins in every measured benchmark category, simply because it is the only processor in this comparison with recorded scores. Its 79th percentile ranking and average score of 26936 demonstrate strong all-around capability. The data shows it performs within 0.6% of the Intel Core i9-9900K and within 0.4% of the AMD Ryzen 7 5700G, both established desktop-class parts. This suggests the 445 can handle demanding mobile workloads including multi-core rendering, as evidenced by its 10590 Cinebench R23 multi-core score, and single-threaded tasks, with a 1806 single-core score.

The Ryzen Embedded 8645HS wins in specifications that favor embedded deployments. Its 5.00 GHz boost clock and 4.30 GHz base clock are higher than the 445's 4.60 GHz and 2.00 GHz respectively. Its 16 MB shared L3 cache is four times larger, which can reduce memory latency for repeated access patterns. Its 20 PCIe Gen 4 lanes provide more connectivity for peripherals and controllers than the 445's 14 lanes. The 45 W TDP, while higher, indicates a design that can sustain full clock speeds without aggressive power management, a common requirement in embedded systems.

For general mobile computing, content creation, and any task that benefits from benchmark-verified performance, the Ryzen AI 7 445 is the clear choice. For embedded applications requiring higher sustained clocks, larger cache, and more PCIe connectivity, the Ryzen Embedded 8645HS offers a compelling specification sheet, though its actual performance remains unmeasured in the database. The two processors share the same socket and memory bandwidth, but their design priorities diverge: the 445 optimizes for efficiency and mobile versatility, while the 8645HS optimizes for throughput and system integration.
