AMD Ryzen 7 5800H Mobile Processors with Radeon Graphics

The AMD Ryzen 7 5800H is a high-performance mobile processor for big laptops launched in January 2021. The Ryzen 7 5800H retains its eight-core design based on the new AMD’s Zen 3 architecture – which offers a significant increase in instructions per clock (IPC), a redesigned core complex with doubled L2 and L3 cache and improved power efficiency. Its 8 core can simultaneously process 16 threads because of SMT support, with a base clock of 3.2GHz and a maximum boost frequency of 4.4GHz. The processor also comes with an integrated Radeon Vega 8 graphics (with eight computing units) clocking up to 2000MHz. The 5800H has a fully unlocked Cezanne die but isn’t quite as highly clocked as AMD’s 5000 H-series processors that, for example, can turbo boost up to 4.8GHz.

Also, like many Ryzen 5000 mobile processors, the chip uses the DDR4-3200 and LPDDR4-4266 memory controllers, PCIe 3.0 connectivity and other features. All this is built on TSMC’s 7nm FinFET processor technology with a default TDP of 45W and a configurable TDP of 34 – 54W which explains why it is intended for big laptops; with better and efficient cooling systems. The 20MB of total cache for this AMD processor consists of 4MB of L2 and 20MB of L3 memory. This is a considerable amount and will certainly result in a competitive performance. Although it might not be as much as Intel’s chips because Intel’s processors typically have 20-25% larger caches; the 5800H should still be potent when it comes to processing capabilities.

As expected, there are many laptops listed with the AMD Radeon Vega 8 GPU for the same 45W TDP. Acer, Asus, Dell, HP are among a few of them to have launched their laptops equipped with this processor, including Alienware. However, the overall performance of the 5800H is quite similar or better compared to Intel’s Core i7-8550U. However, it can provide better processing power for high-quality applications, including video rendering and real-time content creation. That is because of its 8 built-in cores and Hyper-Threading technology offering up to 16 processor threads simultaneously.

That should translate into a performance that is decent overall and won’t be too far off from the Intel Core i7-8550U. Power consumption figures could be better, but should still offer decent efficiency; although it might not shine as much as higher-clocked AMD processors. Overall, the Ryzen 7 5800H should make for a good all-round laptop processor. It could be particularly interesting for those who want to do some video rendering and other intensive tasks like transcoding.
