AMD Ryzen 5 PRO 6650H vs AMD Ryzen 7 7735HS Comparison

The AMD Ryzen 5 PRO 6650H and AMD Ryzen 7 7735HS are two mobile chips built on the same 6 nm Zen 3+ foundation, yet the recorded data shows they land in different places. The Ryzen 7 7735HS takes 16 of the 17 head-to-head benchmark wins, while the Ryzen 5 PRO 6650H claims a single, narrow victory in Geekbench single-core. The database suggests this is less a rivalry than a tier separation: one chip with more cores and higher clocks against one with a PRO designation and a slightly different thermal envelope. What follows is a look at where each one wins, why, and what the underlying silicon tells us.

Head-to-Head Benchmarks

The overall pattern is unmistakable. The Ryzen 7 7735HS dominates every multi-threaded test, usually by a wide margin, and wins most single-threaded tests by a slim one. The Ryzen 5 PRO 6650H's lone win comes in Geekbench single-core, where its 1735 score edges the 7735HS's 1699, a 2.1 percent advantage. That is the only green column in the PRO chip's row, and it is worth questioning what it means: it suggests that in short, bursty single-thread workloads the 6650H can occasionally punch above its tier.

Everywhere else, the story belongs to the 7735HS. In Cinebench R15 multi-core it scores 2153.4 against 1550, a 28 percent gap. Cinebench R23 multi-core repeats the trend: 13106 versus 9561, 27 percent apart. These are sustained rendering workloads, and the 8-core, 16-thread configuration of the 7735HS simply has more parallel throughput than the 6-core, 12-thread 6650H. The recorded data aligns almost perfectly with the core-count ratio of roughly one-third more cores mapping to roughly one-quarter to just under one-third better results.

The Passmark suite tells the same story in detail. Integer math: 85309 versus 62838, a 26.3 percent lead for the 7735HS. Floating point math: 47865 versus 35743, 25.3 percent ahead. Data compression lands at 293278 against 217700 (25.8 percent), data encryption at 18237 against 13518 (25.9 percent), extended instructions at 20050 versus 15044 (25 percent), and random string sorting at 30388 versus 22823 (24.9 percent). The consistency across these very different computational kernels is striking. Whether the workload is memory-bound, integer-heavy, or floating-point intensive, the gap hovers around the mid-twenties in percentage terms.

Passmark multithread shows 23166 against 17936, a 22.6 percent lead, and Passmark physics gives the 7735HS 1073 versus 838, 21.9 percent ahead. Even prime number finding, a lightly threaded workload by nature, goes to the 7735HS by 11.9 percent (59 versus 52).

Single-threaded results are closer. Cinebench R15 single-core: 248 versus 236, a 4.8 percent edge for the 7735HS. Cinebench R23 single-core: 1546 versus 1471, 4.9 percent. Passmark single thread: 3296 versus 3110, 5.6 percent. The boost clock differential, 4.75 GHz on the 7735HS against 4.50 GHz on the 6650H, is a 5.6 percent spread, which matches the single-thread deltas with almost suspicious precision. Then Geekbench single-core breaks the pattern, and that anomaly is the most interesting data point in the entire comparison.

Aggregating the picture: the 7735HS posts an average benchmark score of 25147 against 24364 for the 6650H, placing it in the 77th percentile versus 76 for the 6650H. The averages compress the gap because they mix single and multi-thread results, but the percentile figures confirm both sit in nearly the same overall neighborhood of the database, just with the 7735HS consistently on the higher side.

The Verdict

The data points to a clear division. For any workload that scales with threads, rendering, compression, encryption, physics simulation, the Ryzen 7 7735HS is the stronger choice by roughly 21 to 28 percent across every multi-threaded test recorded. That is not a marginal win; it is a generational-sounding gap achieved within the same architecture.

The Ryzen 5 PRO 6650H, by contrast, holds its own only in short single-threaded bursts, and its one Geekbench single-core win (1735 versus 1699) suggests competent responsiveness for lightly threaded applications. Its "PRO" designation sits outside the benchmark data, but its ECC capability is absent (the field is false) while the 7735HS, curiously, lists ECC support as true. On pure measurements, then, the 6650H's case rests on a narrower set of scenarios than its PRO branding might imply.

If the question is "which chip is faster," the answer from 16 of 17 tests is the 7735HS.

Architecture Differences

On paper these are near-siblings. Both use the Zen 3+ architecture, both are built by TSMC on a 6 nm process, and both target the mobile segment in Socket FP7. Both support DDR5 memory on a dual-channel bus with identical 76.8 GB/s bandwidth, and both expose PCIe Gen 4 with 20 CPU lanes.

The differences are incremental rather than fundamental. The 6650H is codenamed Rembrandt and belongs to the 6000 series; the 7735HS is Rembrandt-R, a refresh in the 7000 series released later. The refresh brings a slightly larger die, 210 mm² versus 208 mm², which tracks with its higher core count. Both share the same cache hierarchy: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. Neither offers 3D V-Cache.

The integrated graphics differ. The 6650H pairs with the Radeon 660M, while the 7735HS ships with the stronger Radeon 680M, consistent with its additional cores. One further distinction: the 7735HS lists ECC memory support as true, where the 6650H does not, an inversion of what the PRO label might lead one to expect.

Both chips remain in active production per the database, and neither has an unlocked multiplier.

Specification Differences

The field-by-field comparison shows few divergences, but each one matters:

• Cores/threads: 6 cores, 12 threads on the 6650H versus 8 cores, 16 threads on the 7735HS.
• Base clock: 3.30 GHz on the 6650H versus 3.20 GHz on the 7735HS. The 6650H actually bases higher, a small but real inversion.
• Boost clock: 4.50 GHz versus 4.75 GHz in favor of the 7735HS.
• TDP: 45 W for the 6650H versus 35 W for the 7735HS. The faster chip carries the lower nominal TDP, an unusual inversion worth noting.
• Series/codename: 6000 series Rembrandt versus 7000 series Rembrandt-R.
• Release date: the 6650H arrived in 2022; the 7735HS followed in 2023.
• Die size: 208 mm² versus 210 mm².
• Integrated graphics: Radeon 660M versus Radeon 680M.
• ECC support: false on the 6650H, true on the 7735HS.

Everything else, process node, socket, cache layout, memory support, PCIe configuration, bandwidth, is identical between the two.

FAQ

Q: How big is the multi-core performance gap?

A: The 7735HS leads by 21.9 to 28 percent across every multi-threaded test, including 27 percent in Cinebench R23 multi-core (13106 versus 9561) and 22.6 percent in Passmark multithread (23166 versus 17936).

Q: Does the Ryzen 5 PRO 6650H win anything?

A: Yes, one test: Geekbench single-core, where it scores 1735 against 1699, a 2.1 percent edge. It loses all other 16 head-to-head comparisons.

Q: Are these chips architecturally different?

A: Only slightly. Both are Zen 3+ on TSMC's 6 nm process with identical cache layouts (64 KB L1 per core, 512 KB L2 per core, 16 MB shared L3) and the same FP7 socket. The 7735HS is the Rembrandt-R refresh of the 6650H's Rembrandt design.

Q: Which has the higher clock speeds?

A: The 7735HS boosts higher at 4.75 GHz versus 4.50 GHz, but the 6650H has the higher base clock at 3.30 GHz versus 3.20 GHz.

Q: Which chip has lower TDP?

A: The 7735HS, at 35 W nominal versus 45 W for the 6650H, despite being the faster performer in the recorded benchmarks.

Q: Do they support the same memory?

A: Yes. Both support DDR5 on a dual-channel bus with 76.8 GB/s of bandwidth. The 7735HS additionally lists ECC memory support, which the 6650H does not.

Where Each One Wins

Ryzen 7 7735HS wins: every multi-threaded workload in the database. Rendering (Cinebench R15 and R23 multi-core by 28 and 27 percent), integer and floating point math (26.3 and 25.3 percent), compression and encryption (25.8 and 25.9 percent), physics (21.9 percent), and most single-threaded tests (4.8 to 5.6 percent). It also carries the stronger Radeon 680M integrated graphics. For threaded productivity work, this is the chip the data endorses.

Ryzen 5 PRO 6650H wins: short single-threaded bursts, evidenced solely by its Geekbench single-core result of 1735. It also posts the higher base clock (3.30 GHz), which may help in sustained-threshold scenarios, though the benchmark data does not isolate this. Its case is narrow but not zero.

The final read: the 7735HS sweeps the performance argument within its own family, and the 6650H's PRO branding does not translate into measurable advantages in the recorded data. The one anomaly, Geekbench single-core, remains an open question the database invites further samples to resolve.
