The AMD Ryzen 7 5800H is part of the Zen 3 ‘Cezanne H’ architecture designed exclusively for notebook computers. We will not see these chips until next year, but performance results have already begun to emerge.
Ryzen’s 5000 Series laptop processors seem to be circulating in a closed circle of users who provide us with some performance results from time to time. The most recent performance test is on the Ryzen 7 5800H chip discovered in the Geekbench database.
AMD Ryzen 7 5800H appears in GeekBench with 8 cores and 16 threads
The Ryzen 7 5800H has 8 cores and 16 threads with a clock speed of 3.2 GHz with 16 MB L3 cache and 4 MB L2 cache. In addition to the better Zen 3 architecture, AMD has increased the L3 cache compared to the Ryzen 4000 series, which should also result in better performance at all levels. On the integrated graphics side, this series will use Vega cores with a 7nm process node. In the case of the 5800H with about 8 CUs or 512 SP.
The values we can see here seem to be low, and this is because we are looking at a technical sample. The processor runs at 3.2 GHz without boost frequencies. Nevertheless, these base frequencies are about 300 MHz above the Ryzen 7 4800H. With the specifications described, the chip should have a TDP of 45 W.
AMD may present the entire Ryzen 5000 laptop family at CES 2021 in January. We are excited to hear the news.
