Athlon 300U vs Core i3-10110U

Both the Athlon 300U and Core i3-10110U share an identical 2-core/4-thread configuration. Boost clocks reach 3.3 GHz on the Athlon 300U versus 4.1 GHz on the Core i3-10110U — a 21.6% clock advantage for the Core i3-10110U (base: 2.4 GHz vs 2.1 GHz). The Athlon 300U uses the Raven Ridge 2 (2019) architecture (14 nm), while the Core i3-10110U uses Comet Lake-U (2019−2020) (14 nm). In PassMark, the Athlon 300U scores 3,861 against the Core i3-10110U's 3,839 — a 0.6% lead for the Athlon 300U. Geekbench 6 single-core — the metric most relevant to gaming — records 900 vs 1,270, a 34.1% lead for the Core i3-10110U that directly translates to higher frame rates. Multi-core Geekbench: 1,800 vs 2,353 (26.6% advantage for the Core i3-10110U). Both processors carry 4 MB (total) of L3 cache.

The Athlon 300U uses the FP5 socket (PCIe 3.0), while the Core i3-10110U uses FCBGA1528 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR4-2400 on the Athlon 300U versus DDR4-2666 on the Core i3-10110U — the Core i3-10110U supports 11.1% faster memory, which can translate to measurable gains in memory-sensitive workloads. The Core i3-10110U supports up to 64 GB of RAM compared to 32 GB — 100% more capacity for professional workloads. Both feature 2-channel memory with ECC support. PCIe lanes: 12 (Athlon 300U) vs 16 (Core i3-10110U) — the Core i3-10110U offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: FP5 (Athlon 300U) and SoC (Core i3-10110U).

Neither processor supports overclocking. Virtualization support: AMD-V (Athlon 300U) vs VT-x, VT-d, EPT (Core i3-10110U). Both include integrated graphics — Radeon RX Vega 3 (Athlon 300U) and UHD Graphics for 10th Gen (Core i3-10110U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Athlon 300U targets Budget Laptop, Core i3-10110U targets Productivity. Direct competitor: Core i3-10110U rivals Ryzen 3 3200U.
