It is not uncommon to convert a mobile graphics card into a desktop card, but in the past it was the RTX30 series of old cards, and now the top-tier RTX4090 and RTX4080 mobile versions are also being targeted. Why this transformation? Generally this is because the mobile version of the GPU consumes less power and generates heat, the heat dissipation design is simpler, the PCB is more cost-effective, and ultimately it is cheaper.
But the price is also very high. Without any quality assurance and official driver support, both performance and stability will be greatly reduced.
In a certain second-hand market,A large number of modified RTX4080M desktop cards suddenly appeared this month. Many of them have similar or even identical appearances, and their performance is said to be between the desktop versions of RTX4070 and RTX4070Ti.
The price is generallyBetween 2000-3000 yuan, not expensive.
There are still very few RTX4090M desktop cards, and the most expensive one actually sells for 13,800 yuan.
With this money, you can definitely find a way to buy a real RTX4090, whether new or second-hand. Even buying an RTX4090D is much better than this.
Next, you may see RTX4070M and RTX4060 desktop cards.
