AMD Ryzen 7 5800U Mobile Processors with AMD Radeon Graphics

The AMD Ryzen 7 5800U is the fastest U-series mobile processor for ultrathin and light laptops that was launched in January 2021. The Ryzen 7 5800U 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.

The Ryzen 7 5800U comes with 8 cores and 16 threads thanks to simultaneous multithreading, with a base clock of 1.9GHz and a maximum boost frequency of 4.4 GHz. There’s 16MB of L3 cache and 4MB of L2 cache, along with an integrated Radeon Vega 8 graphics (with eight computing units) clocking up to 2000MHz. Not all the features of the Ryzen 7 5800U are upgraded.

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 15W and a configurable TDP of 10 – 25W. The 5800U 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.

The 5800U provides some clock frequency improvements over the Ryzen 7 4800U and Ryzen 7 5700U. The base clock is 100MHz higher and the turbo boost is 200MHz higher when compared to the 4800U: while for the 5700U, the maximum boost clock frequency is 100MHz lower. These differences can be attributed to the IPC gains of Zen 3 against the Zen 2 architecture. Furthermore, we also see the L2 and L3 cache is doubled, as we’d expect. The integrated graphics is clocked 100MHz and 250MHz higher than Ryzen 7 5700U and Ryzen 7 4800U respectively.

The AMD Ryzen 7 5800U has a much higher single and multi-threaded performance compared to the Ryzen 4000 processors and some 5000 U-series chips. The 5800U was released in response to Intel’s Tiger Lake processors that provide significant performance improvements over their predecessors. However, the gains seen in the multicore performance of 5800U will still extend AMD’s lead on their Intel counterpart.
