This is a curious case of a GPU switcheroo. There are RTX 3070 graphics playing cards up on the market in Asia with cell RTX 3070 chips in them—the sort meant for gaming laptops, not discrete graphics playing cards. Effectively, it might be somebody who had an abundance of laptop computer GPUs handy and no laptops to place them in, however in fact, it truly seems a play to bypass any cryptocurrency mining restrictions and earn more money.
A Facebook post (opens in new tab) from Vietnam, noticed by leaker I_Leak_VN (opens in new tab), outlines somebody’s hands-on impressions of the so-called RTX 3070M. They point out that “this GPU was beforehand solely used for laptops, now they’ve packed it into low cost VGA.” There is no clear branding seen on the shroud. Nevertheless, it is possible manufactured by a GPU OEM accomplice in China as it is also been noticed on the Chinese language market Taobao and Aliexpress.
The RTX 3070M goes for the equal of $738 on Aliexpress (opens in new tab). That is not notably low cost—you possibly can decide up an RTX 3070 for much less on Newegg (opens in new tab) right this moment—however there’s one other draw for this card’s almost definitely clients: cryptocurrency mining effectivity.
A daily RTX 3070 will function at round 45MH/s when mining ethereum, and that is a diminished price on account of Nvidia’s cryptocurrency mining limiter, Lite Hash Price (LHR), which prevents lots of its discrete graphics playing cards from operating at 100% effectivity when a selected mining workload is recognised.
This cell RTX 3070M is reportedly capable of ship round 65MH/s, utilizing a GPU that was by no means regarded as a lot use to miners and due to this fact by no means got here with any type of crypto-mining limiter put in.

From what I can inform, 65MH/s is the RTX 3070M’s ethereum hash price and never a hybrid price of a number of hashes without delay. Both method, it is reportedly increased than what an LHR RTX 3070 desktop card is ready to ship out of the field.
Although it have to be stated that Nvidia’s LHR lock has been repeatedly broken (opens in new tab) or severely diminished over the course of the previous 12 months, and lots of miners had already thought-about Nvidia’s actions to be largely redundant (opens in new tab) in heading off mining demand for gaming GPUs.
There may be additionally a catch for the RTX 3070M: as listed on the Aliexpress product web page, the RTX 3070M won’t work with Home windows 10, which is nearly actually all the way down to desktop driver points. As a substitute, it requires Linux. That is all tremendous and dandy for crypto-miners that already use Linux for his or her mining rigs, however it does slam the door on an everyday gaming PC operating Home windows with one in every of these playing cards put in.
So in the event you nonetheless thought these have been in any method meant for gaming functions, you would be sorely mistaken.
The profitability of ethereum has slipped in current months, nevertheless, alongside a bigger crypto crash that has seen most of its positive factors this 12 months wiped off. That has seen GPU demand falter for the primary time in a minimum of 18 months. Whereas graphics playing cards are nonetheless too costly, they’re a minimum of now extensively obtainable to buy—the RTX 3070M desktop GPU could also be arriving a bit late to the occasion.
