Nvidia: Phones Aren’t Ready for Ray Tracing

In keeping with Nvidia’s CEO Jen-Hsun Huang, streaming companies like GeForce Now are the easiest way to ship AAA sport experiences to cellular gamers. Ray tracing cellular chips, he claims, are a much less efficient strategy to meet that aim.

“Ray tracing video games are fairly massive, to be sincere. The information set is kind of massive, and there’ll be a time for it,” Huang said. “When the time is true we would think about it.”

Huang’s feedback are in reference to AMD’s announcement earlier this week that the cellular GPU it has developed in partnership with Samsung will help options like ray tracing and variable charge shading.

On the one hand, that is precisely what we’d count on Nvidia to say. The corporate is unlikely to publicly declare AMD had stolen a march on it by bringing ray tracing and VRS to cellular GPUs, even when Nvidia privately believed this was the case.

It’s fascinating, nonetheless, to see Jen-Hsun claiming the problem was sport measurement (it’s unclear if he meant VRAM necessities or when it comes to storage capability) versus die measurement or energy effectivity. Trendy, high-end Samsung smartphones already provide 128GB to 512GB of storage and 8GB to 16GB of RAM.

The addition of ray tracing capabilities despatched die sizes hovering, although it did so for various causes. In Nvidia’s case, the corporate has added specialised hardware blocks for ray tracing and tensor calculations. AMD has added a big L3 cache as a part of its technique for maximizing efficiency.

Each of those methods have elevated absolute die sizes.

GPU die sizes have elevated considerably with the appearance of ray tracing for each AMD and Nvidia GPUs.

This development holds up decrease within the stack as properly. The GTX 1060 was a 200mm sq. die, whereas the TU116 — its nominal alternative — was a 284 mm sq. chip. The 6700 XT is considerably bigger than the 5700 XT it replaces.

We nonetheless have extra questions than solutions relating to the longer term position of this IP throughout AMD and Samsung merchandise. The initially introduced settlement solely states that Samsung will promote the graphics IP in “cellular units, together with smartphones, and different merchandise that complement AMD product choices.” Earlier reviews have urged Samsung’s RDNA-derived IP might be restricted to smartphones and tablets. It isn’t clear if AMD might be constructing any chips of its personal, however a brand new low-power GPU may theoretically be of use to the corporate in embedded, low-end cellular, and ultra-low-power segments.

Samsung will seemingly be the primary cellular firm to ship a ray tracing-enabled GPU to customers, although there’s no telling once we’ll see video games or apps optimized to benefit from it. We might have to see broad ray tracing help throughout all the market first. Jen-Hsun’s reference to probably contemplating such a chip can be fascinating, provided that Nvidia walked away from the patron cellular market some years in the past to deal with automotive. It’s not arduous to think about Nvidia growing its personal graphics options to pair with ARM CPUs and making these chips out there for licensing if the deal is allowed to undergo.
