MagyarAMD Ryzen 7 4800H
The AMD Ryzen 7 4800H is a Renoir APU designed for larger, more powerful laptops with room for better termals. The Ryzen features eight Zen 2 cores running at 2.9 GHz (base clock speed) to 4.2 GHz (Boost). The CPU also has 8 MB of L3 cache and a Vega series integrated GPU. Thread-doubling SMT tech is enabled in this processor, allowing for up to 16 concurrent processing threads.
Architecture
Ryzen 7 4800H is manufactured on the modern 7 nm TSMC process and in part thanks to this fact AMD promises an up to 2x higher performance-per-watt figure compared to Ryzen 3000 series mobile APUs. This isn't the only noteworthy change however as Zen 2 architecture is leagues ahead of the outgoing Zen+ when it comes to single-core performance. Renoir family processors feature up to 8 CPU cores compared to 4 cores of the previous generation mobile AMD CPUs.
A 4800H will work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. The important difference between desktop Ryzen 4000 and mobile Ryzen 4000 processors is that the latter do not have PCI-Express 4.0 support, meaning those blazing-fast NVMe SSDs will be limited to a throughput of 3.9 GB/s.
The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir processor family hub for more information on these CPUs.
Performance
Long-term performance sustainability of any mobile CPU tends to depend heavily on cooling system performance as well as TDP settings of a laptop. That said, the average 4800H in our database beats the Intel Core i7-10875H with ease, approaching the realm of Intel Core i9-10980HK. The Ryzen's single-core performance does not look quite as impressive though as it can trail behind Core i3-1005G1 (a dual-core Ice Lake part) in certain tests. This is not really important as most modern apps will gladly load as many cores as they can get access to.
Graphics
Ryzen 7 4800H features the Radeon RX Vega 7, a 7 CU integrated graphics adapter running at up to 1,600 MHz. The iGPU's underlying architecture is fairly old as of 2021, yet its 448 shaders will let you play many games of 2020 and 2021 as long as you stick to reasonable resolutions and presets. F1 2021 runs well at medium quality, 1080p resolution, to give you an example. A Vega 7 can be as fast as a GeForce GTX 1050 Max-Q, or as slow as an 80 EU Iris Xe; this depends on the benchmark as well as on cooling system performance and TDP settings of a laptop as mentioned above. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.
The Vega definitely supports UHD 2160p monitors at 60 Hz. This iGPU is capable of hardware decoding AVC, HEVC and VP9-encoded videos. There is no AV1 support here.
Power Consumption
Ryzen 7 4800H has a default TDP of 45 W which can be changed to anywhere between 35 W and 54 W by an OEM. The chip is a good fit for gaming laptops as well as portable workstations, with high-performance cooling solution being pretty much a necessity. AMD Ryzen 7 4800HS is a 35 W edition of Ryzen 7 4800H designed for leaner, less power-hungry systems.
