RTX 3070 Mobile, Ray Tracing performance similar to a desktop RTX 3060 Ti?

At present, NVIDIA has not yet announced the mobile version of its GeForce RTX 30 series of graphics cards. However, a V-Ray 5 benchmark of what appears to be a GeForce RTX 3070 Mobile recently appeared (as pointed out by colleagues at VideoCardz), allowing us to take a first look at the Ray Tracing abilities of the Ampere architecture in the mobile arena.

Unfortunately, the data doesn't tell us much about the GeForce RTX 3070 Mobile. Only the presence of 8GB of memory is reported, which we expect to be GDDR6 type like the one on the desktop counterpart.

Before going into the merits, it is worth noting that we should take the results of V-Ray 5 with pliers, since it is a card not yet on the market. Furthermore, the potential in Ray Tracing is not, at present, particularly important for gamers.

Recall that the GeForce RTX 3060 Ti has 38 second generation RT cores for Ray Tracing workloads. The GeForce RTX 2080 Ti, on the other hand, sports 68 RT cores, but these are first generation versions, so performance is lower, while the GeForce RTX 3070 Mobile will likely inherit the 46 RT cores from its desktop counterpart. >
Based on the data, the GeForce RTX 3060 Ti appears to be up to 7.81% faster than the GeForce RTX 3070 Mobile. Keep in mind that the GeForce RTX 3060 Ti is a 200W desktop graphics card, so it should outperform a GeForce RTX 3070 Mobile.



The margin is even smaller when comparing the GeForce RTX 3070 Mobile and the GeForce RTX 2080 Ti. In fact, Turing's previous flagship delivers approximately 4.4% higher ray tracing performance.

The current shortage of NVIDIA GeForce RTX 30 graphics cards may be why the manufacturer is taking so long to launch mobile components. However, some retailers have already listed some gaming notebooks equipped with Ampere GPUs, such as GeForce RTX 3080 Max-Q, RTX 3070-Max-Q and RTX 3060 Max-P. The Mobile variant (sometimes known as Max-P) is basically the full-fledged desktop version, while the Max-Q variant is a scaled down version with a lower power limit and, consequently, lower clock speeds.

Given the number of leaks in the past few days, the presentation of the new mobile graphics cards should now be imminent and the CES 2021 event, to be held in January, could be the ideal stage for NVIDIA.
