AMD Ryzen 7 PRO 8845HS vs AMD Ryzen AI 5 435 Comparison

The AMD Ryzen 7 PRO 8845HS and the AMD Ryzen AI 5 435 are both mobile processors, but the benchmark data shows they serve very different performance tiers. The 8845HS wins all 15 recorded head-to-head comparisons, with the largest margins appearing in heavily threaded workloads. The Ryzen AI 5 435, while slower in every test, still holds a strong position in its own percentile bracket, sitting at the 80th percentile compared to the 8845HS’s 86th percentile. The data suggests a clear split: the 8845HS is for sustained, high-throughput tasks, while the AI 5 435 is a more power-conscious option that trades raw performance for efficiency.

Where Each One Wins

The AMD Ryzen 7 PRO 8845HS dominates every recorded benchmark in the head-to-head table. Its biggest advantage appears in multi-core workloads, where the gap widens dramatically. In Cinebench R23 multi-core, the 8845HS scores 24,565 against 11,333 for the AI 5 435, a delta of 116.8%. That is more than double the score, indicating a substantial lead in rendering and compilation tasks. Similarly, PassMark’s multithread test shows a 50.4% advantage (28,572 vs. 19,000), and data encryption shows an 84.4% lead (20,487 vs. 11,110). These are not marginal wins; the 8845HS is in a different performance class for parallel workloads.

The AMD Ryzen AI 5 435 has no benchmark wins in the recorded data. However, its narrowest deficit is in single-threaded performance. In PassMark single-thread, the AI 5 435 scores 3,734, just 0.7% behind the 8845HS’s 3,762. That is effectively a tie for single-thread responsiveness. The same pattern appears in Cinebench R23 single-core, where the AI 5 435 scores 1,816 versus 3,468, a 91% gap, but that is an outlier compared to the PassMark result. The practical takeaway is that for light, single-threaded tasks like browsing or document editing, the AI 5 435 is close, but for anything that uses multiple cores, the 8845HS pulls far ahead.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 7 PRO 8845HS uses Zen 4 architecture with the Hawk Point codename, while the Ryzen AI 5 435 uses Zen 5 with the Gorgon Point codename. Both are built on a 4 nm process at TSMC, so the manufacturing node is identical. The transistor count and die size are listed only for the 8845HS (25,000 million transistors, 178 mm²), while the AI 5 435 does not have those figures recorded.

Core and cache layouts differ significantly. The 8845HS has 8 cores and 16 threads, while the AI 5 435 has 6 cores and 12 threads. The L1 cache is larger per core on the AI 5 435: 80 KB per core versus 64 KB per core on the 8845HS. The L2 cache is the same at 1 MB per core. The L3 cache, however, is very different: the 8845HS has 16 MB shared, while the AI 5 435 has only 4 MB. That 4x difference in L3 capacity is a major factor in the multi-core performance gap.

Clock speeds also diverge. The 8845HS has a base clock of 3.80 GHz and a boost clock of 5.10 GHz, while the AI 5 435 has a 2.00 GHz base and 4.50 GHz boost. The lower base clock on the AI 5 435 is paired with a much lower TDP: 28 watts versus 45 watts for the 8845HS. That explains the performance difference: the AI 5 435 is designed to fit in thinner, cooler systems, while the 8845HS has more thermal headroom.

Other differences include the socket and PCIe lanes. The 8845HS uses AMD Socket FP7 with 20 PCIe Gen 4 lanes, while the AI 5 435 uses AMD Socket FP8 with 14 PCIe Gen 4 lanes. Both support DDR5 memory in a dual-channel configuration with 89.6 GB/s bandwidth, and both support ECC memory. The integrated graphics differ: the 8845HS uses Radeon 780M, while the AI 5 435 uses Radeon 840M. The AI 5 435 also adds LPDDR5X memory support, which the 8845HS does not list.

The Verdict

The data points to a simple choice. The AMD Ryzen 7 PRO 8845HS is the processor for users who need maximum multi-core throughput in a mobile chassis. Its 116.8% lead in Cinebench R23 multi-core and 84.4% lead in data encryption make it the obvious pick for rendering, code compilation, and heavy batch processing. The 45-watt TDP and 5.10 GHz boost clock indicate a part that is meant to run hard when called upon.

The AMD Ryzen AI 5 435 is for users who prioritize efficiency over peak performance. Its 28-watt TDP and lower base clock (2.00 GHz) suggest it belongs in lighter laptops where battery life and thermals matter more than raw speed. The single-thread PassMark result (3,734 vs. 3,762, within 0.7%) shows that day-to-day responsiveness is nearly identical, so the AI 5 435 does not feel slow in casual use. But any workload that scales across cores will expose the gap: the AI 5 435 has 6 cores versus 8, and only 4 MB of L3 versus 16 MB.

Users who run sustained parallel workloads should pick the 8845HS without hesitation. Users who need a capable processor for standard office work, media consumption, and light productivity, and who want lower power draw, should consider the AI 5 435. The benchmark record does not support any scenario where the AI 5 435 outperforms the 8845HS, but the efficiency trade-off is a legitimate reason to choose it.

Head-to-Head Benchmarks

The largest single win for the 8845HS is in Cinebench R23 multi-core, where it scores 24,565 against 11,333, a delta of 116.8%. This is the standout result, showing a processor that delivers more than double the multi-threaded rendering performance. In Cinebench R15 multi-core, the gap is 46.9% (2,476 vs. 1,686), which is still substantial but less extreme than the R23 result, likely due to the shorter workload duration.

Data encryption shows an 84.4% lead (20,487 vs. 11,110), and random string sorting shows a 68.2% lead (41,867 vs. 24,891). Integer math comes in at a 60% advantage (97,625 vs. 61,026), and extended instructions show a 57% lead (25,434 vs. 16,197). Data compression is 52.6% ahead (343,952 vs. 225,374), while multithread is 50.4% ahead (28,572 vs. 19,000). Find prime numbers shows a 50% delta (87 vs. 58), and floating point math is 45.1% ahead (58,965 vs. 40,627).

The narrower wins are in physics and single-thread tests. Physics shows a 29.2% lead (1,389 vs. 1,075), and PassMark single-thread shows just a 0.7% lead (3,762 vs. 3,734). The Cinebench R15 single-core result is 34.2% in favor of the 8845HS (349 vs. 260), and Cinebench R23 single-core is 91% in favor (3,468 vs. 1,816). The single-thread PassMark result is the only benchmark where the AI 5 435 comes close to matching the 8845HS, which reinforces the idea that the AI 5 435 is competitive for light tasks but falls away quickly as thread count rises.
