AMD Ryzen 9 4900H vs AMD Ryzen 9 5900HX: Comparison

Ryzen 9 4900H vs Ryzen 9 5900HX l3 cache compared

On l3 cache the spread is 50%, Ryzen 9 4900H 8 MB against Ryzen 9 5900HX 16 MB, so Ryzen 9 5900HX takes it. They differ on p-core boost clock too, 4.4 GHz on the Ryzen 9 4900H versus 4.6 GHz on the Ryzen 9 5900HX. Release year is not the same on both, 2020 on the Ryzen 9 4900H versus 2021 on the Ryzen 9 5900HX. They differ on igpu too, AMD Radeon Vega 8 Graphics on the Ryzen 9 4900H versus AMD Radeon Graphics on the Ryzen 9 5900HX. They differ on microarchitecture too, Zen 2, Ryzen 4000 Series "Renoir" on the Ryzen 9 4900H versus Zen 3, Ryzen 5000 Series "Cezanne" on the Ryzen 9 5900HX. There is a split on memory type as well, DDR4-3200, LPDDR4-4266 on the Ryzen 9 4900H versus DDR4, LPDDR4 on the Ryzen 9 5900HX.

Ryzen 9 4900H vs Ryzen 9 5900HX: which one fits your build

Take the Ryzen 9 4900H for gaming laptops of the Ryzen 4000 generation wanting strong 8-core, single-thread-focused performance. It is the wrong buy for buyers specifically wanting maximum multi-threaded ceiling from hyperthreading, the SMT-equipped Ryzen 9 4900HS delivers stronger results in heavily-threaded workloads. Take the Ryzen 9 5900HX for desktop-replacement gaming laptops wanting genuinely top-tier AMD mobile Zen 3 performance. Avoid it for buyers wanting the absolute highest clocks in AMD's HX lineup, the 5980HX offers a modest additional edge at the same core count.

Where the two are identical

The common ground is wider than the gap: total cores, performance cores, efficiency cores, total threads and p-core base clock are identical here. They match on 7 further specifications as well.

Frequently asked questions
