A4-5000 vs Core i7-660UM

The A4-5000 packs 4 cores / 4 threads, while the Core i7-660UM offers 2 cores / 4 threads — the A4-5000 has 2 more cores. Boost clocks reach 1.5 GHz on the A4-5000 versus 2.4 GHz on the Core i7-660UM — a 46.2% clock advantage for the Core i7-660UM. The A4-5000 uses the Kabini (2013−2014) architecture (28 nm), while the Core i7-660UM uses Arrandale (2010−2011) (32 nm). In PassMark, the A4-5000 scores 1,284 against the Core i7-660UM's 1,279 — a 0.4% lead for the A4-5000. Geekbench 6 single-core — the metric most relevant to gaming — records 158 vs 250, a 45.1% lead for the Core i7-660UM that directly translates to higher frame rates. L3 cache: 0 kB on the A4-5000 vs 4 MB (total) on the Core i7-660UM.

The A4-5000 uses the FT3 socket (PCIe 2.0), while the Core i7-660UM uses BGA1288 (PCIe 2.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3L-1600 on the A4-5000 versus DDR3-1066 on the Core i7-660UM — the A4-5000 supports 50.1% faster memory, which can translate to measurable gains in memory-sensitive workloads. The A4-5000 supports up to 16 GB of RAM compared to 8 GB — 100% more capacity for professional workloads. Memory channels: 1 (A4-5000) vs 2 (Core i7-660UM). PCIe lanes: 8 (A4-5000) vs 16 (Core i7-660UM) — the Core i7-660UM offers 8 more lanes for additional GPUs or NVMe drives.

Neither processor supports overclocking. Virtualization support: AMD-V (A4-5000) vs VT-x, VT-d (Core i7-660UM). Both include integrated graphics — Radeon HD 8330 (A4-5000) and HD Graphics (Core i7-660UM) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: A4-5000 targets Entry Laptop, Core i7-660UM targets Budget. Direct competitor: A4-5000 rivals Pentium N3520.
