The Verdict

The data paints a picture of two nearly identical processors with one major divergence. The Ryzen 7 6800H and Ryzen 7 7735HS both land in the 77th percentile of all CPUs, share 8 cores and 16 threads, and produce average benchmark scores within 0.2% of each other. For most workloads, picking one over the other will make little measurable difference.

The 7735HS is the more consistent winner in raw head-to-head tests, taking 15 of 23 comparisons. It wins every 3DMark test, with advantages ranging from 4.4% to 5.4% across thread counts. It also edges ahead in Cinebench R15 and R23, though those margins are slim — between 0.1% and 2.2%. The 7735HS also leads in PassMark single-thread (3296 vs 3212), physics (1073 vs 1046), multithread (23166 vs 23060), and find-prime-numbers (59 vs 57).

However, the 6800H delivers one decisive blow in Geekbench multi-core, scoring 9642 against 8114 — a 18.8% margin. It also wins Geekbench single-core (1761 vs 1699) and several PassMark sub-tests, though those are narrow 0.1% to 0.9% edges.

For buyers, the choice depends on workload. If the priority is the broadest set of wins across mixed benchmarks — particularly 3DMark and Cinebench — the 7735HS is the safer all-rounder. If Geekbench multi-core performance matters most, the 6800H is the clear pick. The 6800H also carries a higher TDP (45W vs 35W), which may indicate more sustained performance headroom in some chassis, though the 7735HS compensates with a 0.05 GHz higher boost clock and adds ECC memory support. There is no launch MSRP listed for either part, so price is not a differentiator in this comparison.

Head-to-Head Benchmarks

The 7735HS sweeps the entire 3DMark suite. In 3DMark 16-threads, it scores 6870 against 6560 for the 6800H, a 4.5% lead. The margin grows slightly at 8 threads: 5697 vs 5392, a 5.4% gap. Even at 2 threads, the 7735HS leads 1773 to 1695 (4.4%). The single-thread 3DMark test shows 912 versus 872, another 4.4% advantage. These are consistent, moderate wins across the board.

Cinebench results are much closer. In R23 multi-core, the 7735HS scores 13106 against 13094 for the 6800H — a 0.1% difference that is essentially noise. R15 multi-core shows a 0.8% edge for the 7735HS (2153.4 vs 2136). Single-core results follow the same pattern: R23 single-core gives 1546 vs 1542 (0.3%), and R15 single-core gives 248 vs 242.5 (2.2%). The 7735HS wins all Cinebench tests, but the margins are negligible.

The Geekbench results flip the script. The 6800H scores 9642 in multi-core, which is 18.8% higher than the 7735HS's 8114. That is the single largest delta in the entire comparison. The 6800H also takes Geekbench single-core at 1761 vs 1699 (3.6%). These results suggest the 6800H has a meaningful advantage in Geekbench's specific workload mix, despite being slower across most other tests.

PassMark results are a mixed bag. The 6800H wins data compression (293929 vs 293278, 0.2%), data encryption (18260 vs 18237, 0.1%), extended instructions (20114 vs 20050, 0.3%), floating-point math (47989 vs 47865, 0.3%), integer math (85397 vs 85309, 0.1%), and random string sorting (30668 vs 30388, 0.9%). The 7735HS counters with wins in find-prime-numbers (59 vs 57, 3.4%), multithread (23166 vs 23060, 0.5%), physics (1073 vs 1046, 2.5%), and single-thread (3296 vs 3212, 2.5%). None of these margins are dramatic, but the 7735HS's single-thread and physics wins are the most notable among the PassMark group.

Specification Differences

The two CPUs diverge on several key specifications, even though their core architecture is identical. The most striking difference is TDP: the 6800H is rated at 45 watts, while the 7735HS draws only 35 watts. That 10-watt gap could influence thermal design and battery life in laptops, though the 7735HS manages to achieve a higher boost clock despite the lower power envelope.

Boost clock is another differentiator. The 7735HS reaches 4.75 GHz, while the 6800H tops out at 4.70 GHz. Base clocks are identical at 3.20 GHz. The die size also differs slightly: the 6800H measures 208 mm², while the 7735HS is 210 mm². Both use the same 6 nm TSMC process.

Memory support shows one notable split. Both CPUs support DDR5 with dual-channel memory and 76.8 GB/s bandwidth, but the 7735HS adds ECC memory support. The 6800H does not offer ECC. Both have the same PCIe Gen 4 with 20 lanes (CPU only), the same Radeon 680M integrated graphics, and the same AMD Socket FP7.

The 7735HS has a later release date of 2023-03-31, while no release date is listed for the 6800H. The part numbers also differ: the 6800H uses 100-000000545100-000000561, while the 7735HS uses 100-000000985(FP7)100-000000989(FP7r2). Neither CPU has an unlocked multiplier, and both are classified as mobile parts with active production status.

Architecture Differences

Both processors are built on the same Zen 3+ architecture with a 6 nm TSMC process node. The 6800H carries the Rembrandt codename, while the 7735HS uses Rembrandt-R. This is a refresh rather than a new architecture, which explains the near-identical performance profile.

Core and cache configurations are identical. Each CPU has 8 cores and 16 threads, with 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache. There is no 3D V-Cache on either part. The 6800H belongs to the 6000 series, while the 7735HS is part of the 7000 series, but the underlying silicon is essentially the same.

The key architectural difference is the Rembrandt-R refresh in the 7735HS. This refresh brings the higher boost clock (4.75 GHz vs 4.70 GHz) and the lower TDP (35W vs 45W) while maintaining the same core count and cache hierarchy. The ECC memory support in the 7735HS is another functional addition, though it does not appear to impact benchmark scores.

Both CPUs share the same 76.8 GB/s memory bandwidth and dual-channel DDR5 support. The integrated Radeon 680M graphics is identical. The 7735HS's die is 2 mm² larger, likely due to the ECC controller or minor refresh changes, but this does not translate into a performance advantage in most tests. The 6800H's 45W TDP might suggest better sustained performance in theory, but benchmark results show the 7735HS winning the majority of tests despite its lower power rating.
