AMD Ryzen 5 8600G vs AMD Ryzen 5 PRO 6650H Comparison

The AMD Ryzen 5 PRO 6650H and AMD Ryzen 5 8600G are both six-core, twelve-thread processors from AMD, but they target fundamentally different market segments. The 6650H is a mobile part for laptops, while the 8600G is a desktop processor with a powerful integrated GPU. The benchmark data reveals a clear generational and architectural gap: the 8600G wins all 17 head-to-head benchmark comparisons, often by substantial margins. However, the 6650H’s lower power envelope and mobile pedigree make it a distinct option for specific use cases, despite its performance deficit.

Where Each One Wins

The performance landscape is entirely one-sided in the recorded benchmarks. The AMD Ryzen 5 8600G wins every single head-to-head test, from single-threaded workloads to heavily multithreaded rendering tasks. There are zero benchmark wins for the Ryzen 5 PRO 6650H. This does not mean the 6650H is without a purpose; its advantage lies outside raw benchmark scores. The 6650H carries a 45 W TDP compared to the 8600G’s 65 W TDP, making it the more power-efficient choice for compact or thermally constrained systems. The 6650H is also a mobile processor on AMD Socket FP7, designed for laptops where the 8600G’s desktop AM5 platform is not applicable.

The 8600G’s wins are decisive in compute-heavy tasks. For example, in Cinebench R23 multi-core, the 8600G scores 21503 against the 6650H’s 9561, a delta of -55.5%. This makes the 8600G the clear choice for content creation, 3D rendering, and any workload that scales across cores. In single-threaded performance, the 8600G also leads, with a Cinebench R23 single-core score of 3035 versus 1471, a -51.5% difference. This advantage extends to everyday responsiveness and lightly threaded applications. The only scenario where the 6650H could be considered a "winner" is in power-constrained mobile environments, where its lower TDP is a practical benefit, though it sacrifices significant performance to achieve it.

Architecture Differences

The two processors represent distinct generations of AMD’s core technology. The Ryzen 5 PRO 6650H is built on the Zen 3+ architecture, codenamed Rembrandt, and fabricated on a 6 nm process at TSMC. In contrast, the Ryzen 5 8600G uses the newer Zen 4 architecture, codenamed Phoenix, on a more advanced 4 nm process from the same foundry. This process shrink is a primary driver of the 8600G’s performance advantage, allowing higher clock speeds and better power efficiency. The 8600G’s base clock is 4.30 GHz and boost clock is 5.00 GHz, while the 6650H runs at 3.30 GHz base and 4.50 GHz boost.

Cache configurations also differ. Both have 64 KB of L1 cache per core and 16 MB of shared L3 cache, but the L2 cache is doubled on the 8600G: 1 MB per core versus 512 KB per core on the 6650H. This larger L2 cache likely contributes to the 8600G’s superior performance in latency-sensitive workloads. The integrated graphics also differ, with the 6650H featuring a Radeon 660M and the 8600G featuring a Radeon 760M. The 8600G also has a larger transistor count (25,000 million) and a slightly smaller die size (178 mm²) compared to the 6650H’s 208 mm² die. The 8600G is a desktop part with an unlocked multiplier, while the 6650H is a mobile part with a locked multiplier. Memory bandwidth is higher on the 8600G at 83.2 GB/s versus 76.8 GB/s, though both support DDR5 in a dual-channel configuration.

Head-to-Head Benchmarks

The benchmark data shows a consistent and overwhelming lead for the Ryzen 5 8600G. In multi-core rendering, the Cinebench R23 result of 21503 for the 8600G versus 9561 for the 6650H represents a 55.5% performance gap. This is the largest delta in the entire test suite. The Cinebench R15 multi-core test shows a smaller but still significant gap, with scores of 2167 and 1550 respectively, a -28.5% difference. Single-core performance is also heavily in favor of the 8600G; the Cinebench R23 single-core score of 3035 is more than double the 6650H’s 1471, a -51.5% delta. The Geekbench results echo this trend, with the 8600G scoring 10850 in multi-core and 2433 in single-core, against the 6650H’s 6930 and 1735, representing -36.1% and -28.7% deltas respectively.

The Passmark suite provides a broader view of everyday computing tasks. The 8600G leads in integer math with a score of 77042 versus 62838, a -18.4% delta, which is one of the narrower gaps. Floating point math shows a -25.4% delta, with scores of 47919 and 35743. Data compression is 25.8% faster on the 8600G, with a score of 293306 compared to 217700. The largest gap in the Passmark suite is in the find prime numbers test, where the 8600G scores 96 versus 52, a -45.8% delta. The 8600G also shows a significant advantage in physics calculations, scoring 1450 against 838, a -42.2% delta. Even in single-threaded Passmark tests, the 8600G leads with 3878 versus 3110, a -19.8% delta. Across all 17 tests, the average delta is -31.6%, with the 8600G winning every single comparison.
