What about AliExpress graphics cards?
We have to start with the graphics cards from AliExpress they are actually laptop models that have been converted. Let’s not forget that just like their desktop counterparts communicate with the PCI Express interface of the processor, the difference is that since they are on the same PCB there is no socket in the middle to plug the card into and they are wired directly through the board itself. Well, the laptop models go at much lower voltages and reduced speeds. Let’s not forget that 150 W is already considered excessive for a laptop graphics card.
Actually, they are the same chips that are used for desktops, but without being accompanied by a complex cooling system and a firmware or graphics BIOS designed to work on a laptop. By using the PCIe interface and selling both the GPU and video memory in one block it’s easy to rip them out and build a graphics card around them.
Well, of the tgraphics cards for mining RIGs, in which, in order to obtain the highest efficiency per watt, they end up reducing their consumption. So we are not talking about your GPU and video memory having been overburned. Simply, that with the move to Ethereum 2.0 they ceased to be useful.
And why were the portable ones used? Well, due to the fact that in the case of NVIDIA, these were not covered via LHR in their day. That is, the assemblers and manufacturers of official cards that did business behind the scenes with the issue of miners did not offer the desktop chips that had the mining disabled, but intelligently the laptop ones. That is, they sacrificed sales of gaming laptops in exchange for temporarily making more money from miners.
Is it worth buying graphics cards from AliExpress
With the price of graphics cards going through the roof, it is normal that the opportunity to launch these products to the market has arisen. In any case, their low price is due to the fact that the materials to build them have been obtained at very low prices. What allows them to burst prices and are, therefore, a sweet candy for less buoyant economies. In any case, we are not the ones to say how you should configure your PC and how to spend your money, we are simply here to inform you about what these AliExpress graphics cards really are.
So why should we be suspicious?
No, it is not for the fact that they may be burned, which they are not. Think that they have worked in optimal conditions to function 24 hours a day and 7 days a week. However, don’t think that by buying an RTX 3070M you are getting an RTX 3070 at a bargain price. If not, you are paying for an inferior product, because the model they sell retains the clocks for the laptop. And this is where the real problem begins.
on laptops there are endless variants of each model, for the simple fact that the manufacturer of the laptop can touch the parameters of the GPU when mounting it in his laptop through some tools that NVIDIA and AMD provide to their partners. So that, you can find models with a 3070 in the laptop market that perform like a 3060M or worse due to the fact of having a cut TDP. If we start from the fact that these graphics card assemblers buy the models in bulk, we can find that from the same consignment and model we have disparate yields.
The other problem with AliExpress graphics cards is after-sales service. On the drivers issue it is a bit complicated, since while AMD uses common drivers for laptop and desktop GPUs, NVIDIA does not. So you will have to take it into account. Although the biggest problem is the guarantee. They are not partners with the GPU manufacturers and therefore if there is a driver issue with certain models they are not going to bother to fix it.
