AMD Ryzen 7 7735U

The AMD Ryzen 7 7735U is a mobile processor in the 7000 series, built on the Zen 3+ architecture under the codename Rembrandt-R. Fabricated by TSMC on a 6 nm process, this chip integrates 8 cores and 16 threads, with a base clock of 2.70 GHz and a boost clock of 4.75 GHz. Its average benchmark score of 26305 places it in the 83rd percentile among all CPUs in the database, signaling a strong performance tier for a mobile part that competes closely with several desktop chips.

Benchmark Performance

The multi-core Cinebench R23 score of 17613 is a standout figure, while the single-core score reaches 2486. In Geekbench, the processor posts 7672 multi-core and 1770 single-core results. Passmark shows a multi-thread score of 20723 and a single-thread score of 3236. Looking at the older Cinebench versions, the R15 multi-core score is 1775 with a single-core score of 250, and the R20 results show 7397 multi-core and 1044 single-core. The average benchmark score of 26305 is nearly identical to its nearest rivals, with deltas of -0.1%, +0.1%, +0.2%, and +0.3% against the Ryzen 5 PRO 5655GE, Ryzen 5 7600X, Ryzen 7 PRO 6850U, and Ryzen 7 5700X respectively. This places the 7735U in a dead heat with both desktop and mobile chips, a remarkable outcome for a 28 W mobile processor. The Passmark data compression score of 250457 and integer math score of 79580 highlight strong compute throughput, while the floating-point math score of 42966 and extended instructions score of 16349 demonstrate robust handling of vectorized workloads. The data encryption score of 15825 indicates solid security processing, and the random string sorting score of 26365 suggests fast data manipulation capabilities.

Platform and Compatibility

The 7735U uses AMD Socket FP7, a mobile-specific socket. Memory support is limited to DDR5, running on a dual-channel bus with a bandwidth of 76.8 GB/s. ECC memory is supported, which is valuable for data integrity in professional workflows. PCIe connectivity is Gen 4 with 20 lanes available from the CPU. The integrated Radeon 680M GPU provides substantial graphics capability without a discrete card. The chip was released on January 3, 2023, and remains in active production. The multiplier is locked, so overclocking is not an option. The part number is listed as 100-000000987(FP7) and 100-000000991(FP7r2). The die size is 208 mm². The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The market segment is explicitly mobile, which aligns with its FP7 socket and 28 W TDP.

Power and Thermals

With a TDP of 28 W, the 7735U falls into the efficient mobile tier. The 6 nm process from TSMC is a key enabler of this power envelope. The 208 mm² die size houses the 8 cores, 16 MB shared L3 cache, and the Radeon 680M graphics. This TDP class implies that a capable cooling solution, such as a well-designed heat pipe assembly in a thin-and-light chassis, is sufficient to maintain boost clocks. The data does not specify cooler dimensions, but the thermal budget is clearly constrained compared to desktop parts. The parity in average score with desktop rivals like the Ryzen 5 7600X and Ryzen 7 5700X, despite the massive power difference, underscores the efficiency of the Zen 3+ architecture. The 6 nm node allows this level of performance within that envelope, making it suitable for passively cooled or low-profile designs where heat dissipation is limited.

Who Should Consider It

This processor is a strong candidate for users who need high multi-threaded performance in a mobile form factor. The Cinebench R23 multi-core score of 17613 indicates capability for video editing, 3D rendering, and software compilation. The Passmark data encryption score of 15825 and extended instructions score of 16349 suggest solid performance for security-sensitive tasks and AVX workloads. For office productivity, the single-thread Passmark score of 3236 ensures snappy responsiveness in everyday applications. Gamers can rely on the integrated Radeon 680M for casual gaming, though the data does not include specific gaming benchmarks. The 83rd percentile ranking means it outperforms the majority of CPUs tracked in the database, making it a versatile choice for a premium ultrabook or a compact workstation. The floating-point math score of 42966 and integer math score of 79580 show strong arithmetic throughput, which benefits scientific computing and financial modeling. The random string sorting score of 26365 indicates fast data manipulation, useful for database operations and scripting workloads.

How It Compares

vs AMD Ryzen 5 PRO 5655GE: The 7735U trails the PRO 5655GE by a razor-thin 0.1% in average score (26305 vs 26320). This delta is within noise, meaning the two chips are effectively tied in overall throughput, despite the 5655GE being a desktop-oriented part.

vs AMD Ryzen 5 7600X: The 7735U leads the 7600X by 0.1% in average score (26305 vs 26272). The 7600X is a desktop processor, yet the mobile 7735U manages to edge it out in aggregate benchmarks, which speaks volumes about the efficiency of the 6 nm process and the Zen 3+ core design.

vs AMD Ryzen 7 PRO 6850U: The 7735U is 0.2% ahead of the PRO 6850U (26305 vs 26262). Both are mobile parts, but the 7735U's slightly higher average score gives it a marginal edge in the same thermal class, likely due to its higher boost clock of 4.75 GHz.

vs AMD Ryzen 7 5700X: The 7735U holds a 0.3% advantage over the 5700X (26305 vs 26214). The 5700X is a desktop chip with a much larger power budget, yet the 7735U's raw multi-thread score of 17613 in Cinebench R23 allows it to compete directly, demonstrating the architectural efficiency of the newer Zen 3+ cores.

Single-Thread vs Multi-Thread Behavior

The ratio of multi-core to single-core scores reveals a well-balanced design. In Cinebench R15, the multi-core score of 1775 is 7.10 times the single-core score of 250. The R20 results show a similar scaling factor of 7.08 (7397 vs 1044), and the R23 results match at 7.08 (17613 vs 2486). This consistent scaling across Cinebench versions indicates excellent parallel utilization of the 8 cores. Geekbench shows a lower scaling factor of 4.33 (7672 vs 1770), indicating that Geekbench's workload does not scale as efficiently across the cores. Passmark multi-thread (20723) is 6.40 times its single-thread (3236). These ratios indicate excellent parallel scaling for a mobile chip. The single-thread performance of 2486 in Cinebench R23 is competitive, ensuring that lightly threaded tasks like web browsing and document editing do not suffer. The multi-thread strength is clearly the defining characteristic, making it suitable for content creation where all cores can be utilized, while the solid single-thread scores prevent bottlenecks in legacy or poorly optimized applications.
