Intel and NVIDIA had an agreement that AMD notebooks, equipped with Ryzen 4000 processors, could not use GeForce graphics cards above the RTX 2060.
Intel and NVIDIA have an agreement that AMD notebooks cannot use the GeForce RTX 2070/2080
While it was initially indicated that the reason was that these Renoir processors had a PCIe 3.0 x8 interface to the GPU, something that limited performance, it finally seems that the real reason was elsewhere.
“According to the information we received, Intel and Nvidia had an agreement signed last year, according to which notebook configurations with AMD Ryzen 4000 processors and graphics cards could not be prepared at the level of the GeForce RTX 2070 and higher,” Polish PurePC web site stated.
According to PurePC, it was one of the notebook manufacturers who revealed this news, indicating that there really was an agreement between Intel and NVIDIA to guarantee that the GeForce RTX 2070 and RTX 2080 were exclusive to the tenth generation of processors from the blue team, the Comet Lake-H.
If we go back in time and look at the recent announcements, we realize that there was obviously something back there. Now, with the AMD Ryzen 5000 (Cezanne-H) you can choose up to a GeForce RTX 3080, even though these CPUs also have 8 PCIe 3.0 lines for the GPU.
