AMD Ryzen 7 5800H

AMD R7 5800H

The AMD Ryzen 7 5800H is a high-performance octa-core processor of the Cezanne product family. It was released in Q1 2021; it is designed for use in larger laptops, primarily gaming laptops and DTRs. The Ryzen features eight SMT-enabled Zen 3 cores running at 3.2 GHz (base clock speed) to 4.4 GHz (highest Boost frequency possible) along with the Vega 8 iGPU. The chip has 16 MB of L3 cache.

Architecture

Ryzen 7 5800H is manufactured on the modern 7 nm TSMC process, just like the outgoing Ryzen 7 4800H was; both CPUs have 8 cores and 16 threads, too. The underlying microarchitecture is what makes the two vastly different as the newer Zen 3 microarchitecture brings a massive IPC improvement over Zen 2. To be specific, AMD promises an increase of up to 19%, with independent reviews pointing to a lower (but sizeable nonetheless) 12% increase.

Ryzen 5 5800H supports dual-channel DDR4-3200 and quad-channel LPDDR4-4266 RAM. Unlike the desktop-grade Ryzen 5000-series processors, Ryzen 5 5800H does not support PCI-Express 4.0, meaning NVMe SSDs will be limited to read/write rates of 3.9 GB/s.

The CPU gets soldered straight on to the motherboard (FP6 socket interface) and is thus not user-replaceable.

Performance

The Ryzen is a marvel of a processor, with its unbelievably high scores no matter the benchmark. This CPU trades blows with the likes of Core i9-10980HK and Core i9-11900H. Needless to say, a 5800H-based laptop will be able to chew through pretty much any workload imaginable for years to come.

Your mileage may vary depending on how high the Power Limits and how competent the cooling solution of a laptop are.

Graphics

In addition to its eight CPU cores, the APU has the Radeon RX Vega 8 graphics adapter. Just like the name suggests, Vega 8 features 8 Compute Units (8 x 64 = 512 unified shaders); in the case of Ryzen 7 5800H, the Vega runs at up to 2,000 MHz.

On paper, this iGPU is inferior to the 96 EU Intel Iris Xe Graphics G7. However, as is usually the case, synthetic benchmarks do not tell the entire story, as AMD's drivers are superior to those of Intel. As a result, the Vega will let you play a lot of games released in 2020 and 2021 at reasonable resolutions (up to Full HD 1080p) and Low to Medium presets. Mass Effect Legendary Edition is playable at 1080p (High), to give you an example. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

The graphics adapter definitely supports 2160p UHD monitors at 60 Hz. AVC, HEVC, MPEG-2, VP9-encoded videos can be hardware-decoded with the Vega but there is no AV1 support here; such a video will be software-decoded for much lower energy efficiency.

Power Consumption

Ryzen 7 5800H is a fairly energy-efficient APU thanks to the modern 7 nm manufacturing process. The APU has a default TDP (also knows as the long-term Power Limit) of 45 W that can be changed to anywhere between 35 W and 54 W by an OEM. No matter the exact value, a high-performance cooling solution is a must.
