Nvidia’s RTX 20-series Max Q GPUs will struggle to deliver a good ray traced experience

RTX. It’s on. And it’s being plumbed into more than 40 different gaming laptops, in over 100 different configurations starting on January 29. Yes, Nvidia has announced mobile GeForce RTX 20-series graphics silicon for gaming laptops at its Sunday night CES press conference. With RTX 2080, RTX 2070, and RTX 2060 versions of its Turing GPU architecture going into the next generation of gaming notebooks there is a whole lot of graphics power going mobile around the end of this month. Like the Pascal generation before it, the 20-series Turing cards will filter down into mobile form using the same basic core configuration as their desktop counterparts. But don’t let that fool you, these mobile GPUs aren’t going to be able to deliver quite the same level of gaming performance as their desk-bound siblings. The top two chips, the RTX 2080 and RTX 2070, are coming in Max Q configurations in systems such as the new Razer Blade 15, which means they’ll dynamically manage the power used by the GPU to fit inside sleek mobile chassis. That means cutting performance by around 10% compared with a full-fat GPU, but Nvidia is still claiming the RTX 2080 laptop chip will be faster than a GTX 1080 desktop graphics card, and 40% more efficient too.
