Core i3-4370 vs Athlon 300U

Both the Core i3-4370 and Athlon 300U share an identical 2-core/4-thread configuration. Boost clocks reach 3.8 GHz on the Core i3-4370 versus 3.3 GHz on the Athlon 300U — a 14.1% clock advantage for the Core i3-4370 (base: 3.8 GHz vs 2.4 GHz). The Core i3-4370 uses the Haswell (2013−2015) architecture (22 nm), while the Athlon 300U uses Raven Ridge 2 (2019) (14 nm). In PassMark, the Core i3-4370 scores 3,854 against the Athlon 300U's 3,861 — a 0.2% lead for the Athlon 300U. Geekbench 6 single-core — the metric most relevant to gaming — records 904 vs 900, a 0.4% lead for the Core i3-4370 that directly translates to higher frame rates. Multi-core Geekbench: 2,071 vs 1,800 (14% advantage for the Core i3-4370). Both processors carry 4 MB (total) of L3 cache.

The Core i3-4370 uses the LGA1150 socket (PCIe 3.0), while the Athlon 300U uses FP5 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3-1600 on the Core i3-4370 versus DDR4-2400 on the Athlon 300U — the Athlon 300U 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 i3-4370) vs 12 (Athlon 300U) — the Core i3-4370 offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: Intel H81,Intel B85,Intel H87,Intel Z87,Intel H97,Intel Z97 (Core i3-4370) and FP5 (Athlon 300U).

Virtualization support: true (Core i3-4370) vs AMD-V (Athlon 300U). Both include integrated graphics — Intel HD Graphics 4600 (Core i3-4370) and Radeon RX Vega 3 (Athlon 300U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Athlon 300U targets Budget Laptop.
