    It's not eurocom, there is no mobile connector for NVLINK and nvidia is not supporting any development of it in a mobile form factor.

    [QUOTE = "Meaker @ Sager, post: 10988731, member: 11947"] Это не eurocom, нет мобильного разъема для NVLINK, и nvidia не поддерживает его разработку в мобильном форм-факторе. [/ QUOTE]
    Спасибо, прояснили;)

    This is old news. SLI Checkerboard Frame Rendering (CFR) was an experimental multi-GPU rendering mode that appeared in Nvidia drivers toward the end of last year and could be enabled using Nvidia Profile Inspector. It works in DX12 and Vulkan applications, unlike traditional driver-based Alternate Frame Rendering (AFR) mode, which is limited to DX11 and older APIs, and avoids some of the pitfalls inherent to AFR, such as increased input lag and microstutter. However, CFR requires NvLink, meaning there is no possibility for it to work on mobile GPUs, scales poorly (generally 30-40%), and can be quite glitchy. Clearly it was a feature not ready for prime time, so Nvidia eventually removed the CFR code from its more recent drivers.

    Да, вы правы. Перечитал еще раз статью и нашел упоминание, что соединение NvLink необходимо ...
