RTX 3070 desktop VS RTX 3070 Laptop

RTX 3070 desktop VS RTX 3070 Laptop

What’s an RTX 3070 worth in a laptop compared to its big sister PC?

As you all know, Ampere has been making its way into laptops since the beginning of the year. Nvidia GPUs offer a significant gain over the RTX 20xx generation. However, the readability of the offer has been considerably altered with different TGPs for the same GPU.

The RTX 3070 for Notebooks, a best seller?

If you look at the gaming notebook angle alone, the RTX 3070 “mobile” is a decent GPU upgrade but not revolutionary for next generation gaming notebooks. Compared to its big sisters, the 3070 is up to 15% faster than the RTX 2070 Super and about 30% faster than the RTX 2070 with an equivalent configuration. The gains are not as significant as those we saw when comparing Turing to Ampere in desktop versions. However, it is difficult to get more performance when power is limited by heat dissipation. We had all noticed that despite the switch to 8nm, the Ampere generation had a high TGP. In the case of a notebook PC, the GPU will not be able to “express itself” completely, which explains why there is not as much delta as with desktop PCs.

When choosing an RTX 3070 in your laptop, you will have to keep an eye on the GPU configuration

In particular, buyers will need to be vigilant and probably avoid 80W “Max-Q” configurations because the gains compared to the same PC in RTX 3060 are low. In general, the RTX 3070 in the “80W” version does not have as good a price/performance ratio as the “mobile” RTX 3060.

The comparison between the RTX 3070 Mobile and the PC now needs to be discussed

We’re not going to make the suspense last but the laptop version does not provide the performance of the desktop version of the RTX 3070 at all. We are even very far from it. Two products with a performance delta greater than 50% should simply not have the same name from our point of view. Obviously this is not new but Nvidia has tended to bring the performance of the two platforms (PC / Laptop) closer together in recent years. This generation is moving away from this trend quite frankly. The risk is obviously that a novice buyer will expect the level of performance found on conventional PCs equipped with an RTX 3070. To get an idea, we publish here some tests performed by Techspot between an RTX 3070 desktop and an RTX 3070 laptop.
