Currently AMD laptops feature 4000 series processors, also known as Renoir. While these chips have been shown to perform more efficiently than their Intel counterparts, no laptops have come to the market that pair a Renoir sku with an Nvidia RTX 2070 or higher.
According to several laptop manufacturers, this decision was made based on the maximum number of pcie 3.0 lanes of the Ryzen 4000 CPUs. Compared to the 16 lanes of Intel’s Comet Lake H processors, AMD’s Renoir chips have to do by half, which would affect the performance of the graphics card. An OEM has now told the Polish company PurePC that there is another reason.
The best Asus ROG Zephyrus G14 with an AMD CPU will be equipped with a Ryzen 9 4900HS and a mobile RTX 2060 GPU.
For example, Nvidia and Intel are said to have signed a deal, whereby video cards from the RTX 2070 can only be combined with an Intel processor of the tenth generation. While further details are lacking, it can in any case be established that the laptop builders have adhered to this agreement.
The argument of the shortage of pcie lanes now seems to have been debunked, as manufacturers such as Gigabyte and Asus showed new models at the CES show that combine an AMD CPU with a high-end Nvidia GPU. The Ryzen 5000 SKUs with the Cezanne architecture would still have eight pcie 3.0 lanes.
The laptop builders may have opted for chips from the red camp because of the lack of Intel’s Tiger Lake H45 gaming processors. In the corridors it is claimed that this series will be available around June at the earliest.
