Core i3-6006U vs Core i3-3225

Both the Core i3-6006U and Core i3-3225 share an identical 2-core/4-thread configuration. Boost clocks reach 2 GHz on the Core i3-6006U versus 3.3 GHz on the Core i3-3225 — a 49.1% clock advantage for the Core i3-3225 (base: 2 GHz vs 3.3 GHz). The Core i3-6006U uses the Skylake (2015−2016) architecture (14 nm), while the Core i3-3225 uses Ivy Bridge (2012−2013) (22 nm). In PassMark, the Core i3-6006U scores 2,273 against the Core i3-3225's 2,276 — a 0.1% lead for the Core i3-3225. Geekbench 6 single-core — the metric most relevant to gaming — records 630 vs 558, a 12.1% lead for the Core i3-6006U that directly translates to higher frame rates. Multi-core Geekbench: 1,313 vs 1,142 (13.9% advantage for the Core i3-6006U). L3 cache: 3 MB on the Core i3-6006U vs 3 MB (total) on the Core i3-3225.

The Core i3-6006U uses the BGA1356 socket (PCIe 3.0), while the Core i3-3225 uses LGA1155 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR4-2133 on the Core i3-6006U versus DDR3-1600 on the Core i3-3225 — the Core i3-6006U 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: 12 (Core i3-6006U) vs 16 (Core i3-3225) — the Core i3-3225 offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: Skylake-U (Core i3-6006U) and H77,Z77,Q77,B75,P67,Z68,H67 (Core i3-3225).

Neither processor supports overclocking. Virtualization support: Yes (Core i3-6006U) vs VT-x, EPT (Core i3-3225). Both include integrated graphics — HD Graphics 520 (Core i3-6006U) and HD Graphics 4000 (Core i3-3225) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i3-6006U targets Mobile, Core i3-3225 targets Budget. Direct competitor: Core i3-3225 rivals Phenom II X4 965 BE (125W).
