Athlon 300U vs Core i3-4370

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

The Athlon 300U uses the FP5 socket (PCIe 3.0), while the Core i3-4370 uses LGA1150 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR4-2400 on the Athlon 300U versus DDR3-1600 on the Core i3-4370 — 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: 12 (Athlon 300U) vs 16 (Core i3-4370) — the Core i3-4370 offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: FP5 (Athlon 300U) and Intel H81,Intel B85,Intel H87,Intel Z87,Intel H97,Intel Z97 (Core i3-4370).

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