AMD Ryzen 7 5700 vs AMD Ryzen 7 7730U Comparison

The AMD Ryzen 7 7730U and AMD Ryzen 7 5700 share the same Zen 3 architecture, the same 7 nm TSMC process, and the same 10,700 million transistors on a 180 mm² die. Yet the benchmark data reveals a complete sweep: the Ryzen 7 5700 wins all 17 head-to-head comparisons, with deltas ranging from a modest 8.9% to a dominant 50.1%. This is not a close contest; it is a systematic performance gap driven by power envelope and platform positioning. The 7730U, a 15-watt mobile part, cannot match the 65-watt desktop chip, despite being released later. The data tells a clear story of segmentation over generation.

Head-to-Head Benchmarks

The largest single gap appears in Cinebench R23 multi-core, where the Ryzen 7 5700 scores 20,655 against the 7730U’s 10,801.5. That is a 47.7% deficit for the mobile chip. Single-core R23 shows an even starker relative difference: the 5700’s 2,916 versus 1,454.5 represents a 50.1% lead. These two results alone establish the desktop part as the clear compute winner. Cinebench R15 tells the same story but with smaller margins: multi-core 2,082 vs 1,830 (12.1% delta), single-core 293 vs 231 (21.2% delta). The pattern is consistent across rendering workloads.

GeekBench results reinforce the trend. In multi-core, the 5700 posts 9,959 against 6,565, a 34.1% advantage. Single-core shows 1,907 vs 1,541, a 19.2% gap. The desktop chip is not just faster in raw threaded workloads; it also leads in lightly threaded tasks, which suggests clock speed differences matter even for single-thread performance. The 5700’s boost clock of 4.60 GHz versus 4.50 GHz on the 7730U is a small nominal difference, but the sustained performance headroom from a 65-watt TDP likely explains the larger real-world spread.

PassMark’s specialized tests show where the 5700 pulls away most. Data compression: 316,699 vs 225,023 (28.9% delta). Data encryption: 20,096 vs 14,258 (29.1% delta). Extended instructions: 21,945 vs 14,619 (33.4% delta). The gap narrows for integer math, where the 5700’s 90,091 beats 72,352 by 19.7%. Floating-point math sees a 25.2% delta (51,427 vs 38,460). The smallest margin in the entire set is PassMark single-thread: 3,296 vs 3,004, an 8.9% delta. This suggests that when both chips are limited to one core, the desktop part’s higher clocks and power headroom still win, but the relative advantage shrinks considerably.

The remaining PassMark benchmarks follow the same pattern. Multi-thread: 24,303 vs 18,037 (25.8% delta). Physics: 984 vs 751 (23.7% delta). Random string sorting: 33,138 vs 23,651 (28.6% delta). Find prime numbers: 58 vs 45 (22.4% delta). There is no benchmark in the shared set where the 7730U comes out ahead. The deltaPct values are all negative for the mobile chip, and the wins column shows 17 for the 5700 and 0 for the 7730U.

The Verdict

From the data alone, the AMD Ryzen 7 5700 is the superior processor in every measured category. Anyone prioritizing compute performance — rendering, encoding, heavy multitasking, or sustained multi-threaded workloads — should choose the 5700 without hesitation. Its Cinebench R23 multi-core score is nearly double that of the 7730U, and its GeekBench multi-core lead is 34.1%. The desktop chip also wins in single-threaded tests, though by smaller margins, meaning it is not just a multi-core specialist. The 5700’s 78th percentile rank among all CPUs matches the 7730U’s, but the average benchmark score of 25,517 versus 25,625 for the 7730U shows they sit at nearly identical overall levels in the broader database — despite the head-to-head sweep.

The Ryzen 7 7730U is only viable for a specific niche: mobile systems where power consumption is critical. Its 15-watt TDP versus 65 watts for the 5700 is the defining difference. The data does not show any performance advantage for the 7730U, so the choice is not about speed — it is about form factor and thermal budget. If a system must run on battery and dissipate minimal heat, the 7730U is the only one of the two that fits that requirement. The 5700 is a Socket AM4 desktop part, which means it requires a desktop motherboard and cooling solution. The 7730U uses Socket FP6, designed for laptops. There is no scenario in the benchmark data where the 7730U wins, so the verdict rests entirely on platform constraints.

Architecture Differences

Both processors are built on Zen 3 architecture with the Cezanne codename (the 7730U is specifically Barcelo-R, a refresh of Cezanne). They share the same 7 nm TSMC process node, the same 10,700 million transistors, and the same 180 mm² die size. The core counts are identical: 8 cores and 16 threads each. Cache structure is also the same: 64 KB L1 per core, 512 KB L2 per core, and 16 MB of shared L3 cache. The generation field lists both as "Ryzen 7 (Zen 3 (Cezanne))", though the 7730U is in the 7000 series and the 5700 is in the 5000 series. The 7730U was released on 2023-01-03, while the 5700 came earlier on 2022-04-03.

The key architectural difference is not in the core design but in the integrated graphics. The 7730U includes Radeon Graphics (Vega 8), while the 5700 has no integrated graphics at all. This is a major functional divergence: the mobile chip can drive a display without a discrete GPU, whereas the desktop chip requires a separate graphics card. Both support DDR4 memory with dual-channel configuration and a memory bandwidth of 51.2 GB/s, and both support ECC memory. The PCIe implementation differs: the 7730U has Gen 3 with 16 lanes (CPU only), while the 5700 has Gen 3 with 20 lanes (CPU only). This gives the desktop part more expansion headroom for storage or other devices.

Specification Differences

The most consequential specification gap is TDP: 15 watts for the 7730U versus 65 watts for the 5700. This explains the benchmark results more than any other factor. Base clocks differ substantially: the 7730U runs at 2.00 GHz, while the 5700 starts at 3.70 GHz. Boost clocks are closer but still favor the desktop chip: 4.50 GHz vs 4.60 GHz. The socket is different — FP6 for the mobile part, AM4 for the desktop part. The 7730U has an unlocked multiplier set to false, meaning it cannot be overclocked; the 5700 has an unlocked multiplier set to true, allowing user overclocking. The 7730U has no launch MSRP listed, while the 5700 has a launch MSRP of $179. The market segments differ as expected: Mobile for the 7730U, Desktop for the 5700. Both are listed as Active in production status.

Where Each One Wins

The Ryzen 7 5700 wins in every performance category measured. For multi-threaded rendering, its Cinebench R23 score of 20,655 is nearly double the 7730U’s 10,801.5. For content creation and data-heavy tasks, its PassMark data compression score of 316,699 versus 225,023 and encryption score of 20,096 versus 14,258 show clear superiority. For mixed workloads, its GeekBench multi-core of 9,959 outpaces 6,565. Even in lightly threaded scenarios, the 5700 leads, as seen in its Cinebench R23 single-core of 2,916 versus 1,454.5. The desktop chip also wins in smaller margins, such as PassMark integer math (90,091 vs 72,352) and floating-point math (51,427 vs 38,460). The only area where the 5700 does not win is power efficiency, but the data shows no benchmark where that translates into a performance win for the 7730U.

The Ryzen 7 7730U has no benchmark wins to claim. Its value lies entirely outside raw performance: it is a mobile processor with a 15-watt TDP and integrated Vega 8 graphics, making it suitable for laptops that need CPU performance without a discrete GPU. Its Socket FP6 and mobile market segment mean it belongs in thin-and-light systems or portable workstations where the 5700’s 65-watt TDP and AM4 socket are impossible to accommodate. The 7730U’s 4.50 GHz boost clock is close to the 5700’s 4.60 GHz, but the base clock of 2.00 GHz versus 3.70 GHz shows the mobile chip is tuned for burst performance rather than sustained load. In short, the 5700 is the performance winner in every test, while the 7730U is the only option for battery-powered, compact systems that still need 8 cores and 16 threads.
