Core i7-4600M vs Core i5-6300U

Both the Core i7-4600M and Core i5-6300U share an identical 2-core/4-thread configuration. Boost clocks reach 3.6 GHz on the Core i7-4600M versus 3 GHz on the Core i5-6300U — a 18.2% clock advantage for the Core i7-4600M (base: 2.9 GHz vs 2.4 GHz). The Core i7-4600M uses the Haswell (2013−2015) architecture (22 nm), while the Core i5-6300U uses Skylake (2015−2016) (14 nm). In PassMark, the Core i7-4600M scores 3,204 against the Core i5-6300U's 3,207 — a 0.1% lead for the Core i5-6300U. Geekbench 6 single-core — the metric most relevant to gaming — records 1,025 vs 967, a 5.8% lead for the Core i7-4600M that directly translates to higher frame rates. L3 cache: 4 MB (total) on the Core i7-4600M vs 3 MB on the Core i5-6300U.

The Core i7-4600M uses the PGA946 socket (PCIe 3.0), while the Core i5-6300U uses BGA1356 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3L 1600 MHz on the Core i7-4600M versus DDR4-2133 on the Core i5-6300U — the Core i7-4600M supports 199.9% faster memory, which can translate to measurable gains in memory-sensitive workloads. Both support up to 32 GB of RAM. Both feature 2-channel memory with ECC support. PCIe lanes: 16 (Core i7-4600M) vs 12 (Core i5-6300U) — the Core i7-4600M offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: Intel HM86,Intel HM87,Intel QM87 (Core i7-4600M) and Skylake-U (Core i5-6300U).

Neither processor supports overclocking. Virtualization support: true (Core i7-4600M) vs VT-x, VT-d, EPT (Core i5-6300U). Both include integrated graphics — Intel HD Graphics 4600 (Core i7-4600M) and HD Graphics 520 (Core i5-6300U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i7-4600M targets Mobile, Core i5-6300U targets Mainstream Laptop. Direct competitor: Core i5-6300U rivals PRO A12-9800B.
