AMD Ryzen 5 PRO 5655GE vs AMD Ryzen 7 7730U Comparison

Head-to-Head Benchmarks

The data paints a fascinating split between these two Zen 3 parts. The AMD Ryzen 5 PRO 5655GE, a desktop chip, flexes its muscle in sustained multi-threaded workloads and single-core performance, while the AMD Ryzen 7 7730U, a mobile processor, counters with its own wins in a few specialized tests. The most dramatic gap appears in Cinebench R23, where the 5655GE scores 15,504 multi-core against the 7730U's 10,801.5 — a commanding 43.5% lead. That margin is even larger in Cinebench R23 single-core: 2,188 versus 1,454.5, a 50.4% advantage for the desktop part. These are not small differences; they represent a generational gap in sustained performance capability between a 65W desktop socket and a 15W mobile design.

However, the older Cinebench R15 test tells a different story. In R15 multi-core, the 7730U wins decisively with 1,830 points versus 1,562 for the 5655GE, a -14.6% delta in favor of the mobile chip. The R15 single-core result also goes to the 7730U: 231 versus 220, a -4.8% margin. This conflicting data between R15 and R23 is noteworthy. It suggests the 7730U may excel in shorter, bursty workloads that fit within its thermal envelope, while the 5655GE's advantage compounds over longer render times where sustained boost clocks matter more.

The PassMark suite reveals a more nuanced picture. The 5655GE wins 10 of the 15 head-to-head comparisons, but many of those wins are narrow. In passmark_multithread, the 5655GE edges ahead with 18,057 versus 18,037 — a razor-thin 0.1% delta that is effectively a tie. Data compression and encryption are similarly close: 228,037 versus 225,023 (1.3%) and 14,509 versus 14,258 (1.8%), respectively. The desktop chip also takes random string sorting (23,769 versus 23,651, 0.5%), find prime numbers (49 versus 45, 8.9%), and extended instructions (15,714 versus 14,619, 7.5%).

The 7730U's clearest wins come in integer math and physics. It scores 72,352 in passmark_integer_math against 67,582 for the 5655GE, a 6.6% improvement. In passmark_physics, the mobile chip posts 751 versus 648, a 13.7% edge. Floating point math is nearly identical: 38,460 versus 38,204, a 0.7% margin for the 7730U. The single-thread PassMark result goes the other way, with the 5655GE scoring 3,240 versus 3,004 — a 7.9% advantage, confirming the Cinebench R23 single-core finding.

Looking at overall averages, the two chips are far closer than their Cinebench R23 scores suggest. The 5655GE's average benchmark score is 25,880, while the 7730U sits at 25,625. Both occupy the 78th percentile among all CPUs. The 5655GE's nearest rival is the Intel Core i7-11700K, with a delta of 0.3%, while the 7730U's closest competitor is the AMD Ryzen 5 6600H at 0.3% — both chips are essentially trading blows with their respective peer groups. The 5655GE also edges the AMD Ryzen 5 230 by 0.4% and trails the AMD Ryzen AI 5 340 by 0.4%, while the 7730U is 0.4% ahead of the Intel Xeon D-2752TER and 0.4% ahead of the AMD Ryzen 7 5700.

The Verdict

The benchmark data suggests a clear split in intended use cases. The AMD Ryzen 5 PRO 5655GE is the stronger choice for sustained, long-duration multi-threaded workloads — its 43.5% lead in Cinebench R23 multi-core and 50.4% lead in R23 single-core are decisive. Anyone running render jobs, compiling code, or performing extended calculations should prefer the desktop part. Its 10 head-to-head wins, including encryption and data compression, reinforce this positioning.

The AMD Ryzen 7 7730U, despite being a mobile chip with a 15W TDP, holds its own in specific areas. It wins integer math by 6.6% and physics by 13.7%, making it surprisingly capable for simulation or physics-based tasks. Its wins in Cinebench R15 suggest it handles shorter bursts of activity well, which aligns with typical mobile usage patterns. For users prioritizing power efficiency and portability, the 7730U's 15W TDP against the 5655GE's 65W TDP is a substantial differentiator, though the data shows it sacrifices sustained multi-core performance.

The average benchmark scores are nearly identical — 25,880 versus 25,625 — meaning neither chip is a universal winner. The 5655GE is the pick for desktop users who need maximum sustained throughput. The 7730U is the pick for mobile users who need acceptable performance in a dramatically lower power envelope. The 8-core/16-thread configuration of the 7730U does not translate into a performance advantage in most tests, which indicates the 5655GE's higher clock speeds and desktop power delivery matter more than raw core count in these benchmarks.

Specification Differences

The two processors diverge most significantly in their physical and power characteristics. The Ryzen 5 PRO 5655GE has a 65W TDP, while the Ryzen 7 7730U is rated at just 15W — a 50W gap that explains much of the performance delta in sustained workloads. The 5655GE uses AMD Socket AM4 for desktop motherboards, while the 7730U uses AMD Socket FP6 for mobile platforms. The 5655GE's base clock is 3.40 GHz with a boost of 4.40 GHz, whereas the 7730U has a base clock of 2,000.00 MHz (2.00 GHz) and a higher boost of 4.50 GHz. The 7730U's higher boost clock does not translate into better sustained performance, as shown in the benchmarks.

Core and thread counts differ: the 5655GE has 6 cores and 12 threads, while the 7730U has 8 cores and 16 threads. Cache is identical in size per level — 64 KB L1 per core, 512 KB L2 per core — but the L3 cache is listed as 16 MB for the 5655GE and 16 MB (shared) for the 7730U. Both support DDR4 memory in dual-channel configuration with 51.2 GB/s bandwidth, and both support ECC memory. PCIe connectivity is the same: Gen 3 with 16 lanes (CPU only). The integrated graphics differ: the 5655GE features Radeon Vega 7, while the 7730U has Radeon Graphics (Vega 8), indicating one additional compute unit on the mobile part.

The 5655GE was released on 2024-05-06, while the 7730U was released on 2023-01-03. The 5655GE's part number is 100-000001514, and the 7730U's is 100-000000942. Neither chip has an unlocked multiplier. The 5655GE is classified as a Desktop processor, while the 7730U is classified as Mobile. Both are currently marked as Active in production status.

Architecture Differences

Both processors share the same fundamental architecture: Zen 3, built on TSMC's 7nm process with 10,700 million transistors and a 180 mm² die size. The foundry is identical. The core design is the same, which is why cache hierarchies match. However, the codenames differ: the 5655GE is Cezanne, while the 7730U is Barcelo-R. Barcelo-R is a refresh of the Cezanne architecture, which explains why the transistor count and die size are identical.

The 5655GE is part of the 5000 series, while the 7730U belongs to the 7000 series, but both are listed under the same generation description: "Ryzen 5 (Zen 3 (Cezanne))" for the 5655GE and "Ryzen 7 (Zen 3 (Cezanne))" for the 7730U. This confirms they are architecturally the same design, differentiated primarily by binning, power envelope, and platform.

The integrated graphics differ slightly, with Vega 7 on the 5655GE and Vega 8 on the 7730U, but both rely on the same Vega architecture. Memory support is identical — DDR4, dual-channel, 51.2 GB/s — and both support ECC. PCIe lanes are the same: Gen 3 with 16 lanes. The key architectural takeaway is that these are the same silicon at heart; the performance differences stem from the 65W desktop power delivery of the 5655GE versus the 15W mobile power budget of the 7730U, not from any fundamental design change. The 7730U's higher boost clock of 4.50 GHz versus 4.40 GHz suggests it can momentarily reach higher frequencies, but the desktop chip's ability to sustain performance over time wins out in most benchmarks.
