AMD Ryzen 7 6800U vs AMD Ryzen 7 7735U Comparison

Head-to-Head Benchmarks

The benchmark data presents a split decision between these two AMD mobile processors. The AMD Ryzen 7 6800U claims victory in 6 of the 17 recorded tests, while the AMD Ryzen 7 7735U takes the remaining 11. However, the magnitude of those wins tells a more nuanced story than the raw win count.

The most decisive advantage belongs to the Ryzen 7 6800U in Geekbench testing. It scores 9,002 in multi-core, which is 19.8% ahead of the 7735U's 7,216. The single-core gap is nearly as large at 17.2%, with the 6800U posting 1,742 against 1,442. These are substantial margins that suggest a meaningful difference in how the two chips handle certain workloads.

Cinebench results also favor the 6800U, though by narrower margins. In Cinebench R23 multi-core, the 6800U scores 10,546 versus 10,085, a 4.4% advantage. The single-core R23 test shows a smaller 1.1% gap (1,506 vs 1,490). Similarly, Cinebench R15 multi-core gives the 6800U a 4.4% lead (1,776 vs 1,698), and single-core R15 shows a 3.3% edge (242 vs 234).

The 7735U counters with consistent, if modest, wins across the Passmark suite. Its best relative performance comes in data compression (250,457 vs 244,082, a 2.6% lead) and extended instructions (16,349 vs 15,935, also 2.6%). Integer math shows a 2.4% advantage (79,580 vs 77,731), while single-thread performance is 2.2% higher (3,236 vs 3,166). The 7735U also edges ahead in floating-point math (42,966 vs 42,246, 1.7%), multithread (20,723 vs 20,350, 1.8%), and random string sorting (26,365 vs 25,954, 1.6%). Data encryption and physics tests show smaller leads of 1.4% and 1.2% respectively. The prime numbers test is a dead heat at 57 points each.

Looking at overall averages, the 7735U holds a slight edge with an average benchmark score of 28,350 against the 6800U's 27,887. This places the 7735U at the 80th percentile of all CPUs, one point above the 6800U's 79th percentile.

A: The 7735U has a TDP of 28 watts, while the 6800U is rated at 15 watts. This 13-watt difference is notable given that both share the same 6 nm process node and 208 mm² die size.

Q: Which chip has more benchmark wins overall?

A: The 7735U wins 11 of the 17 head-to-head tests, while the 6800U wins 6. However, the 6800U's victories include the largest margins, particularly in Geekbench where it leads by nearly 20%.

Architecture Differences

Both processors share the same fundamental architecture. They use AMD's Zen 3+ design, with the 7735U carrying the Rembrandt-R codename and the 6800U using the original Rembrandt designation. Both are built on TSMC's 6 nm process node with a 208 mm² die size.

The core configuration is identical: 8 cores and 16 threads. Cache hierarchies match exactly, with 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. Memory support is also the same, with DDR5 running on a dual-channel bus at 76.8 GB/s bandwidth.

Connectivity features are shared as well. Both use AMD Socket FP7 and offer PCIe Gen 4 with 20 lanes from the CPU. The integrated graphics solution is the Radeon 680M in both cases.

The key architectural differences are minor but measurable. The 7735U has a slightly higher boost clock at 4.75 GHz versus 4.70 GHz. The 7735U supports ECC memory, while the 6800U does not. The 7735U is part of the 7000 series with the Rembrandt-R codename, while the 6800U belongs to the 6000 series with the original Rembrandt codename.

The 7735U carries a release date of January 2023, while the 6800U has no recorded release date in the database. Both processors remain in active production status. Neither chip has an unlocked multiplier, so overclocking is not supported on either model.

The Verdict

The data paints a clear picture for different use cases. The AMD Ryzen 7 6800U is the stronger choice for applications that benefit from Geekbench performance, where it leads by 17.2% to 19.8%. This includes general system responsiveness and single-threaded tasks that scale with that benchmark's workload characteristics.

The AMD Ryzen 7 7735U is the better pick for Passmark-focused workloads. It wins 11 of 17 tests, with its strongest showings in data compression, extended instruction sets, and integer math. The margins are smaller, ranging from 1.2% to 2.6%, but they are consistent across the Passmark suite.

The 7735U's higher TDP of 28 watts versus 15 watts suggests it is designed for systems that can sustain higher power draw. The 6800U's lower TDP may be preferable for thinner, more power-conscious laptops, though the database does not include battery life or thermal measurements.

For users who rely heavily on Geekbench scores as a proxy for everyday performance, the 6800U is the data-backed choice. For those whose workflows align with Passmark's test suite, particularly data compression and encryption tasks, the 7735U offers a slight but consistent edge.
