Core i7-3770S vs Core i5-8250U

Both the Core i7-3770S and Core i5-8250U share an identical 4-core/8-thread configuration. Boost clocks reach 3.9 GHz on the Core i7-3770S versus 3.4 GHz on the Core i5-8250U — a 13.7% clock advantage for the Core i7-3770S (base: 3.1 GHz vs 1.6 GHz). The Core i7-3770S uses the Ivy Bridge (2012−2013) architecture (22 nm), while the Core i5-8250U uses Kaby Lake Refresh (2017−2019) (14 nm). In PassMark, the Core i7-3770S scores 6,173 against the Core i5-8250U's 6,158 — a 0.2% lead for the Core i7-3770S. Geekbench 6 single-core — the metric most relevant to gaming — records 694 vs 1,127, a 47.6% lead for the Core i5-8250U that directly translates to higher frame rates. L3 cache: 8192 kB (total) on the Core i7-3770S vs 6 MB (total) on the Core i5-8250U.

The Core i7-3770S uses the LGA1155 socket (PCIe 3.0), while the Core i5-8250U uses BGA1356 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3-1600 on the Core i7-3770S versus DDR4-2400 on the Core i5-8250U — the Core i5-8250U supports 28.6% 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 i7-3770S) vs 12 (Core i5-8250U) — the Core i7-3770S offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: Z77,H77,B75,Z68,P67,H67 (Core i7-3770S) and Kaby Lake-R (Core i5-8250U).

Neither processor supports overclocking. Virtualization support: VT-x, VT-d (Core i7-3770S) vs VT-x, VT-d, EPT (Core i5-8250U). Both include integrated graphics — HD Graphics 4000 (Core i7-3770S) and UHD Graphics 620 (Core i5-8250U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i7-3770S targets Budget, Core i5-8250U targets Mainstream Laptop. Direct competitor: Core i5-8250U rivals Ryzen 5 2500U.
