AMD Ryzen 5 6600H vs AMD Ryzen 7 5700 Comparison

The AMD Ryzen 5 6600H and AMD Ryzen 7 5700 are two very different processors that happen to land at nearly the same overall performance level. The Ryzen 5 6600H is a 6-core mobile part built on Zen 3+ with DDR5 support, while the Ryzen 7 5700 is an 8-core desktop part built on Zen 3 with DDR4 support. Their average benchmark scores are nearly identical — the 6600H scores 25550 and the 5700 scores 25517, a delta of just 0.1% — yet the data shows a complete sweep in individual tests: the Ryzen 7 5700 wins all 17 head-to-head benchmarks. This creates an unusual situation where the aggregate scores suggest parity, but the workload-level results tell a story of consistent, often large, advantages for the desktop chip.

Q: Do both processors share the same socket and platform?

A: No. The Ryzen 5 6600H uses AMD Socket FP7, which is a mobile socket, while the Ryzen 7 5700 uses AMD Socket AM4, a desktop socket. The 6600H has PCIe Gen 4 with 20 lanes, while the 5700 has PCIe Gen 3 with 20 lanes.

Where Each One Wins

The benchmark data is unambiguous: the AMD Ryzen 7 5700 wins every single head-to-head test against the Ryzen 5 6600H. There is no workload category where the 6600H comes out ahead. The 5700’s margin ranges from a narrow 3.6% in Passmark single-thread to a dominant 50% in Cinebench R23 both multicore and singlecore. This means the desktop chip is the clear choice for any performance-focused application, from lightly threaded tasks like single-core productivity to heavily threaded workloads like video rendering or scientific computing. The 6600H’s only advantage is not in performance but in platform characteristics — it is a mobile processor with integrated Radeon 660M graphics, which makes it suitable for laptops where discrete GPUs are not present. For a user prioritizing raw compute, the 5700 is the only option based on the data.

However, the use-case split is not about which chip wins benchmarks, but about where each belongs. The 6600H is designed for the mobile market segment, with a 45 W TDP and DDR5 support, making it a fit for thin-and-light or mainstream gaming laptops. The 5700 is a desktop processor with a 65 W TDP, an unlocked multiplier, and ECC memory support, positioning it for DIY desktop builds, workstations, or small form factor systems where upgradeability and memory reliability matter. In purely performance terms, the 5700 is superior across the board, but the 6600H offers an integrated GPU and a more power-efficient process node, which are relevant for portable systems.

Architecture Differences

The two processors come from different generations and process nodes. The Ryzen 5 6600H is built on the Zen 3+ architecture, codenamed Rembrandt, using a 6 nm TSMC process with a die size of 208 mm². The Ryzen 7 5700 is built on the older Zen 3 architecture, codenamed Cezanne, using a 7 nm TSMC process with a die size of 180 mm². The 6600H is part of the 6000 series and represents a mobile-focused refresh that adds DDR5 support and an integrated Radeon 660M GPU. The 5700 is part of the 5000 series and is a desktop chip with no integrated graphics.

Another key difference is the transistor count and memory interface. The 5700 has 10,700 million transistors, while the 6600H’s transistor count is not listed. The 6600H supports DDR5 memory with a bandwidth of 76.8 GB/s, while the 5700 supports DDR4 with 51.2 GB/s. This means the mobile chip has a theoretical memory bandwidth advantage of about 50%, although the 5700 compensates with more cores and higher clocks in actual tests. The 6600H also has a smaller L3 cache at 16 MB shared, identical to the 5700’s 16 MB L3, but the 5700 has no integrated graphics, freeing up die area for compute.

The socket and platform are also fundamentally different. The 6600H uses AMD Socket FP7, a BGA-style mobile socket, while the 5700 uses AMD Socket AM4, a PGA-style desktop socket. The 6600H has PCIe Gen 4 with 20 lanes, while the 5700 has PCIe Gen 3 with 20 lanes. This means the mobile chip has a newer PCIe standard, but the desktop chip has a more established ecosystem with a wide range of AM4 motherboards. The 5700 also has an unlocked multiplier, allowing for overclocking, while the 6600H is locked.

Specification Differences

The specification differences are substantial beyond the core count. The Ryzen 5 6600H has 6 cores and 12 threads, while the Ryzen 7 5700 has 8 cores and 16 threads. The 5700 has higher base and boost clocks: 3.70 GHz base and 4.60 GHz boost versus 3.30 GHz base and 4.50 GHz boost for the 6600H. The TDP also differs significantly, with the 6600H rated at 45 W and the 5700 at 65 W.

Memory support is a major differentiator: the 6600H uses DDR5 with 76.8 GB/s bandwidth, while the 5700 uses DDR4 with 51.2 GB/s. The 5700 supports ECC memory, while the 6600H does not. The integrated graphics also differ — the 6600H has a Radeon 660M, while the 5700 has none. The 6600H has a part number of 100-000000546100-000000562, while the 5700 has 100-000000743. The 5700 has a release date of 2022-04-03 and a launch MSRP of $179, while the 6600H has no release date or MSRP listed. Finally, the 5700 has an unlocked multiplier, while the 6600H is locked.

Head-to-Head Benchmarks

The head-to-head results show a complete sweep for the AMD Ryzen 7 5700, but the margins vary widely by workload. The largest wins come in Cinebench R23, where the 5700 doubles the 6600H’s score. In multicore, the 5700 scores 20655 versus 10322, a delta of -50% for the 6600H. In single-core, the 5700 scores 2916 versus 1458, also a -50% delta. This is a massive gap that suggests the 5700’s combination of 8 cores and higher clocks provides nearly twice the rendering performance in both single-threaded and multi-threaded Cinebench workloads.

In Geekbench, the 5700 leads by smaller but still significant margins. The multicore score is 9959 versus 7444, a 25.3% advantage, and the single-core score is 1907 versus 1566, a 17.9% advantage. This indicates that the 5700 is about a quarter faster in general-purpose multi-threaded tasks and nearly a fifth faster in single-threaded tasks, despite the 6600H’s newer Zen 3+ architecture and DDR5 support.

The Passmark suite shows a pattern of consistent wins for the 5700, with deltas ranging from -3.6% to -29%. The closest test is Passmark single-thread, where the 5700 scores 3296 versus 3178, a narrow 3.6% lead. The largest Passmark win is in data encryption, where the 5700 scores 20096 versus 14277, a 29% advantage. Data compression shows a 27.4% lead (316699 versus 229879), and extended instructions show a 27.5% lead (21945 versus 15903). Integer math and random string sorting both show a 27.9% lead for the 5700, while floating point math shows a 28.5% lead (51427 versus 36796).

The smallest overall delta is in Passmark find prime numbers, where the 5700 scores 58 versus 52, a 10.3% advantage. Passmark physics shows a 9.5% lead (984 versus 891), and Passmark multithread shows a 23.2% lead (24303 versus 18669). Across all 17 tests, the 5700’s smallest win is in Passmark single-thread at 3.6%, and its largest win is in Cinebench R23 at 50%. The data shows that while the aggregate scores are within 0.1%, the Ryzen 7 5700 is clearly the stronger performer in every measured workload, making the 6600H’s parity in average score a result of the benchmark suite’s weighting rather than actual performance equivalence.
