Athlon 3000G vs Core i3-8100H

The Athlon 3000G packs 2 cores / 4 threads, while the Core i3-8100H offers 4 cores / 4 threads — the Core i3-8100H has 2 more cores. Boost clocks reach 3.5 GHz on the Athlon 3000G versus 3 GHz on the Core i3-8100H — a 15.4% clock advantage for the Athlon 3000G (base: 3.5 GHz vs 3 GHz). The Athlon 3000G uses the Zen+ (2018−2019) architecture (14 nm), while the Core i3-8100H uses Coffee Lake-H (2018−2019) (14 nm). In PassMark, the Athlon 3000G scores 4,446 against the Core i3-8100H's 4,435 — a 0.2% lead for the Athlon 3000G. L3 cache: 4 MB (total) on the Athlon 3000G vs 6 MB on the Core i3-8100H.

The Athlon 3000G uses the AM4 socket (PCIe 3.0), while the Core i3-8100H uses BGA1440 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches 2666 on the Athlon 3000G versus DDR4-2666 on the Core i3-8100H — the Athlon 3000G supports 199.4% faster memory, which can translate to measurable gains in memory-sensitive workloads. Both support up to 64 of RAM. Both feature 2-channel memory with ECC support. Both provide 16 PCIe lanes.

Only the Athlon 3000G has an unlocked multiplier for overclocking — a significant advantage for enthusiasts seeking extra performance. Virtualization support: true (Athlon 3000G) vs VT-x, VT-d (Core i3-8100H). Both include integrated graphics — Radeon Vega 3 Graphics (Athlon 3000G) and UHD Graphics 630 (Core i3-8100H) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i3-8100H targets Mobile. Direct competitor: Athlon 3000G rivals Pentium Gold G6400.
