AMD Ryzen 5 PRO 6650H vs Intel Core i7-13620H Comparison

The Verdict

The Intel Core i7-13620H is the decisive winner in this comparison. Across every single recorded head-to-head benchmark, the Intel part takes the victory, with 15 wins and zero losses. The average benchmark score for the Intel chip is 24911, placing it in the 77th percentile of all CPUs, while the AMD Ryzen 5 PRO 6650H averages 24364, sitting at the 76th percentile. That small overall gap hides a much larger performance chasm in specific workloads. The Intel Core i7-13620H should be the pick for anyone prioritizing raw compute throughput, particularly in multi-threaded rendering, scientific calculations, and prime number workloads. The AMD Ryzen 5 PRO 6650H, while trailing in every measured test, does offer a smaller die and a more power-efficient process node, but the data shows no scenario where it outperforms the Intel part. For users who need maximum performance in mobile workstations or high-end laptops, the Intel Core i7-13620H is the clear choice. The AMD part remains a capable processor, but it is not competitive with the Intel offering in any recorded metric.

Architecture Differences

The two processors come from different design philosophies. The Intel Core i7-13620H uses the Raptor Lake-H architecture, built on a 10 nm process at Intel's own foundry. It packs 10 cores and 16 threads, with a base clock of 2.40 GHz and a boost clock of 4.90 GHz. The cache hierarchy is substantial: 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. Memory support includes both DDR4 and DDR5, running on a dual-channel bus. PCIe connectivity is Gen 5 with 8 lanes from the CPU. The integrated graphics are UHD Graphics 770. This chip launched on 2023-01-03 with a launch MSRP of $502.

The AMD Ryzen 5 PRO 6650H uses the Zen 3+ architecture, codenamed Rembrandt, built on a 6 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.30 GHz and a boost clock of 4.50 GHz. The cache is smaller: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. Memory support is limited to DDR5, still on a dual-channel bus, with a recorded memory bandwidth of 76.8 GB/s. PCIe connectivity is Gen 4 with 20 lanes from the CPU. The integrated graphics are Radeon 660M. This chip launched on 2022-04-18 and has no recorded launch MSRP in the database. The die size for the AMD part is 208 mm², while no die size is recorded for the Intel chip.

The core count difference is the most striking architectural split: 10 cores versus 6 cores, and 16 threads versus 12 threads. That directly explains the large multi-threaded gaps. The Intel chip also has a higher boost clock, 4.90 GHz versus 4.50 GHz, which supports its single-thread advantage. The AMD part counters with a smaller process node, 6 nm versus 10 nm, and a wider PCIe lane count, 20 versus 8, but those features do not translate into benchmark wins. Neither chip supports ECC memory, and neither has an unlocked multiplier. The sockets differ as expected: Intel BGA 1744 for the Intel chip, AMD Socket FP7 for the AMD chip.

Where Each One Wins

The Intel Core i7-13620H wins in every recorded category. There is no workload in the database where the AMD Ryzen 5 PRO 6650H takes a lead. That said, the magnitude of the Intel advantage varies considerably by workload type, which suggests different use cases can still see different relative experiences.

For multi-threaded productivity, the Intel chip is dominant. In Cinebench R23 multi-core, the Intel score is 15176 versus 9561, a 58.7% advantage. That translates directly to faster rendering, video encoding, and compilation tasks. The PassMark multithread score shows a 34.9% gap, with 24192 versus 17936. For users running heavy parallel workloads, the Intel part is unequivocally the better choice.

For single-threaded responsiveness, the Intel chip also leads, but by a smaller margin. Cinebench R23 single-core shows 1833 versus 1471, a 24.6% gap. PassMark single-thread shows 3589 versus 3110, a 15.4% gap. This matters for everyday app launch times, light coding, and general desktop snappiness. The Intel chip holds the edge, but the AMD part is not far behind in this category.

For specialized math and encryption tasks, the Intel chip wins by a wide margin. PassMark find prime numbers shows 99 versus 52, a 90.4% gap. PassMark floating point math shows 59762 versus 35743, a 67.2% gap. PassMark physics shows 1671 versus 838, a 99.4% gap. These are extreme divergences that point to the Intel chip's superior computational throughput in scientific and simulation workloads.

For memory and data manipulation, the Intel chip leads again. PassMark data compression shows 281335 versus 217700, a 29.2% gap. PassMark random string sorting shows 29395 versus 22823, a 28.8% gap. PassMark integer math shows 80948 versus 62838, a 28.8% gap. The Intel chip's larger L3 cache and higher core count likely drive these wins.

The AMD chip has no recorded wins, so it cannot be recommended for any specific workload based on performance data. Its only advantages are architectural: a smaller process node, a smaller die, and more PCIe lanes. Those are relevant for system integration and power considerations, but not for benchmark scores.
