AMD Ryzen 7 6800HS vs Intel Core i7-12800H Comparison

The AMD Ryzen 7 6800HS and Intel Core i7-12800H are two mobile processors with distinct design philosophies. The data shows a clear split: Intel wins the majority of head-to-head benchmarks with 12 wins, while AMD secures 3 significant victories in specific workloads. The Intel Core i7-12800H posts a higher average benchmark score of 32121, while the AMD Ryzen 7 6800HS reaches 32354, placing both in the 82nd and 83rd percentiles of all CPUs respectively. This near-identical overall standing, despite vastly different architectures, makes the choice depend heavily on the intended workload.

Where Each One Wins

The Intel Core i7-12800H dominates in raw multi-threaded performance, as evidenced by its 21.5% lead in Cinebench R23 multi-core with a score of 15283 versus the AMD's 11992. This advantage extends to other compute-heavy tasks, with Intel ahead by 22% in PassMark floating point math (60961 vs 47533) and by 40% in PassMark physics (1682 vs 1009). Single-core performance also favors Intel, with a 20.4% lead in Cinebench R23 single-core (1828 vs 1455) and a 7.4% advantage in PassMark single-thread (3440 vs 3184). The Intel chip is the clear choice for rendering, physics simulations, and any application that scales with core count or benefits from high single-core speed.

Conversely, the AMD Ryzen 7 6800HS wins in three specific efficiency-oriented tasks. It leads by 22.6% in PassMark extended instructions (20114 vs 16408), a metric that often reflects cryptographic and specialized instruction throughput. It also wins in PassMark data encryption by 11.5% (18104 vs 16234) and PassMark data compression by 7.1% (292698 vs 273247). These wins suggest the AMD architecture is more efficient at handling data-intensive, security-related, and compression workloads. For users dealing with encrypted files, compressed archives, or specialized math instructions, the AMD chip offers a tangible performance edge.

Architecture Differences

The fundamental difference lies in the core design. The Intel Core i7-12800H uses the Alder Lake-H architecture with a hybrid design, featuring 14 cores and 20 threads. The AMD Ryzen 7 6800HS uses the Zen 3+ Rembrandt architecture, offering 8 cores and 16 threads. This explains the multi-core advantage for Intel, which fields 6 more cores. The process nodes also differ significantly: Intel uses a 10 nm process, while AMD uses a 6 nm process from TSMC. Despite the smaller node, the AMD chip has a die size of 208 mm², slightly smaller than Intel's 217 mm².

Cache configurations show a distinct split. Intel allocates 24 MB of shared L3 cache, while AMD provides 16 MB. However, Intel's per-core L1 cache is 80 KB, and L2 cache is 1.25 MB per core, whereas AMD uses 64 KB L1 and 512 KB L2 per core. Intel's larger cache pool likely contributes to its higher single-core scores. Memory support also differs: Intel supports both DDR4 and DDR5, while AMD supports only DDR5. The Intel chip has a higher base clock of 2.40 GHz and a higher boost clock of 4.80 GHz, compared to AMD's 3.20 GHz base and 4.70 GHz boost. The TDP also varies, with Intel rated at 45 W and AMD at a more power-efficient 35 W.

The Verdict

The data points to a straightforward conclusion for most users: the Intel Core i7-12800H is the superior processor for general productivity and heavy computational tasks. Its 21.5% lead in Cinebench R23 multi-core and 20.4% lead in single-core are decisive. Users who render video, compile code, or run complex simulations will see significant performance gains with Intel. The 45 W TDP suggests this chip is designed for thicker, performance-oriented laptops.

The AMD Ryzen 7 6800HS, with its 35 W TDP, is positioned for a different segment. Its wins in encryption and compression, combined with its lower power draw, make it attractive for users who prioritize battery life and deal with data-centric workloads. The data does not show a performance penalty for AMD in these tasks; rather, it shows a specialized strength. For a user whose primary tasks involve file compression or encrypted data handling, the AMD chip offers a measurable advantage despite losing the overall benchmark war. The choice is not about which is "better" overall, but which aligns with the specific workload profile.

Head-to-Head Benchmarks

The most dramatic deltas are in Intel's favor. The Cinebench R23 multi-core test shows Intel scoring 15283 against AMD's 11992, a -21.5% delta. This is a massive gap that indicates Intel's hybrid architecture with more cores is far more effective in heavily threaded rendering workloads. The Cinebench R23 single-core test shows a similar trend, with Intel at 1828 and AMD at 1455, a -20.4% delta, proving Intel's per-core performance is also superior. In PassMark physics, Intel's score of 1682 dwarfs AMD's 1009, a -40% difference, reinforcing Intel's strength in simulation and physics-based tasks.

AMD's wins are equally telling, though fewer. The PassMark extended instructions test shows AMD at 20114 versus Intel's 16408, a +22.6% delta. This is not a marginal victory; it is a substantial lead in a specific instruction set category. The data encryption test shows AMD at 18104 against Intel's 16234, an 11.5% advantage. The data compression test shows AMD at 292698 versus Intel's 273247, a 7.1% lead. These results indicate that while Intel excels in general math and physics, AMD has optimized its architecture for data manipulation and security-related tasks.
