Yet another example of an unofficial Nvidia GPU is now for sale, and while it’s a good deal on the surface, you should think twice before buying such a card.
This time, we’re talking about an Nvidia GeForce RTX 3070 TiM. If the name doesn’t sound familiar, that’s because it’s not an actual desktop graphics card; Instead, it’s a mobile card that has been changed to fit a desktop PC.
This unusual RTX 3070 TiM graphics card has appeared for sale on AliExpress. Made by a small GPU maker 51Risc, the GPU is definitely a desktop model, but inside the shroud, you’ll find the mobile version of Nvidia’s official laptop RTX 3070 Ti.
While the name is similar, it should come as no surprise that the laptop card offers significantly worse specifications than its desktop counterpart. The vendor-spec RTX 3070 TiM features Nvidia’s GA104 (GN20-E) chip, while the desktop RTX 3070 Ti is equipped with a full GA104-400 GPU. Let’s compare the specs between the two cards.
The “legitimate” desktop RTX 3070 Ti comes with 6,144 CUDA cores and clock speeds between 1,580MHz and 1,770MHz, as well as 8GB of 19GT/s GDDR6X memory. The mobile version sports 5,888 CUDA cores, a boost clock of up to 1,485MHz, and 8GB of 14Gt/s GDDR6 memory.
The RTX 3070 TiM, on the other hand, doesn’t exactly mimic the mobile card’s specifications, but it’s pretty close with 5,888 CUDA cores, a maximum clock speed of 1,410MHz, and 8GB of 17.5GT/s memory. It’s actually closer to the RTX 3060 Ti (desktop) in terms of specs, with a lower clock speed and a slightly higher TDP.
Now, that’s the advantage of this card versus the real RTX 3070 Ti – it has a significantly lower TDP than the real thing, the 3070 Ti has a TDP of 290 watts while the converted mobile card only hits 220 watts; The RTX 3060 Ti maxes out at 200W.
The seller attached a Geek3D Furmark test, which showed that the card never went above 64 degrees Celsius so the temperature is under control and it delivers 70 watts compared to the desktop model. It costs about $340 in comparison to the rough You will have to spend on the RTX 3060 Ti, which can be considered on par with this GPU. 51Risc also offers free shipping from China to the US, so it may sound like a good deal, but there’s a catch.
To use this card, you must use the mobile drivers, even if the card is installed on the desktop. VideoCardz also states that you’ll have to rely on third-party software for the GPU, as Nvidia apparently doesn’t support the RTX 3070 TiM in any shape or form. This isn’t an official card, and it comes with downsides including a limited warranty and no expectation of Nvidia’s help should any trouble arise.
We’ve seen some of these “Frankenstein” graphics cards before, but we’d never recommend them in our ranking of the best GPUs. Even with the deceptive name, these types of cards still work and do quite well most of the time, but usually, you can get a better deal just by buying an official GPU.
In the case of the RTX 3070 TiM, you can just get the RTX 3060 Ti and skip the hassle of dealing with unofficial software. On the other hand, pricing may vary; The 3070 TiM may be cheaper than the 3060 Ti in your area.
