What kind of GPU year can we expect from Nvidia, one of the two largest consumer-grade GPU producers in the world? The answer is somewhat up in the air, because Nvidia is in a solid-yet-fluid position. Market worries and announcement-filled event cancellations hover on one end, while the company's surprisingly bullish financial guidance stands out on the other.
Either way, we've reached April without the company's usual announcement of some new desktop hardware by March's end, and we still don't know when wholly new desktop GPUs might come (more on that later). Instead, we start this month with a different wave of products: a new slate of laptop-grade GPUs, albeit not that new.
Nvidia has announced a wave of "Max-Q" GPUs coming to laptops from 25 OEMs by the end of April, and most, but not all, come from the company's RTX line of GPUs. This month's wave of GPUs consists of three new laptop SKUs (RTX 2080 Super, RTX 2070 Super, GTX 1650 Ti) and slight updates to four existing SKUs (RTX 2070, RTX 2060, GTX 1660 Ti, GTX 1650). Each of these GPUs is built upon the manufacturer's Turing 12nm architecture.
But as we learned from last year's "Super" line of desktop GPUs, those updates mostly consist of mild-yet-welcome jumps on nearly identical silicon, which is what we're seeing in two new Max-Q Super options. Both new Super Max-Q cards benefit the most from an apparent jump in maximum boost clocks, though it remains to be seen how those numbers bear out in the wild. Last year's cards launched with different maximum wattage counts, and that may be the same this time around as well. And they have very slight bumps in tensor core capacity, which is directed primarily at DirectX-based ray tracing and proprietary Nvidia RTX effects (like DLSS, which we get into later). Otherwise, they both continue to have 8GB of GDDR6 memory with a maximum of 448GB/s memory bandwidth, and they have each received a slight bump in "CUDA core" processing units (up 4.6 percent on the 2080 Super and 11.1 percent on the 2070 Super).
A press-only briefing ahead of the cards' reveal showed Nvidia coming up with ways to get further gains from these cards, which is why they tooted the horn of a few new features exclusive to this year's models. The biggest, dubbed "Dynamic Boost," sees Nvidia partnering with OEMs to manage the shared thermal workload of both the CPU and GPU and to fudge up to 15W of power from one motherboard element to the other based on any application's live frame-time data. Meaning, if these sensors, as activated on the driver level, detect that either the GPU or CPU has been pushed to its maximum and that the other half could spare some power, the system will then redirect its total wattage accordingly.
"All of this is free"
Nvidia representatives estimate that this system-level tweak will result in a performance boost of roughly 4 to 8 percent in any game. "But all of this is free," Nvidia's marketing director, Mark Aevermann, said in a phone interview with Ars Technica. "[The performance] was sitting there locked away because a controller wasn't smart enough to do this in the past." Worth noting, this feature requires total buy-in from an OEM before shipping a laptop with a new Nvidia GPU, owing to the system-level optimizations that Nvidia needs to confirm. So don't expect it to get patched into existing laptops with older GPUs. Additionally, as of press time, AMD CPUs do not work with Nvidia Dynamic Boost, and that support will arrive "shortly thereafter," Aevermann said.
Aevermann mentioned additional tweaks designed to drive even smaller performance gains, including voltage optimizations for both the GPUs' GDDR6 memory and for the GPUs' general voltage regulators. These result in 1-2W of power recovery, Aevermann said, which they admitted was mild but insisted was crucial: "We want every half-watt, quarter-watt, one-watt savings to drive the GPU core."
Last on the optimization list is a feature that sounds great: "Advanced Optimus." This is Nvidia's term for a new connector protocol to guarantee that a laptop's integrated-graphics solution doesn't get in the way of an Nvidia Max-Q GPU's direct connection to a laptop's display. Aevermann said that this is simply a more streamlined way for OEMs to guarantee screen technologies like variable refresh rates (G-Sync, FreeSync) and frame rates up to 144fps and beyond, even though we've seen both in Nvidia-powered laptops from the past two years.
