AMD Radeon RX 6600M Desktop Cards Now Selling For Less Than $200
A while ago, we reported on the NVIDIA RTX 30 Rename laptop GPUs As complete desktop cards and they are sold on Chinese websites. It looks like these companies have recently started selling the Radeon RX 6000 series for mobile as well.
One might wonder why anyone would buy a laptop GPU to function as a desktop card, but in fact there is a very good reason. These cards are much cheaper than desktop models. What most likely happens here is that some companies buy laptop GPUs in bulk, which are cheaper than desktops, and then install them on desktop boards.
Ultimately, models like the Radeon RX 6600M are offered as low as $180-189, while the “real” desktop RX 6600 comes in at $269 from the same stores. That’s a pretty big difference for almost the same specs.
And speaking of specs, the RX 6600M is basically the same model as a desktop GPU. Both feature Navi 23 GPU and have very similar boost clocks in the 2.4-2.5GHz range. There isn’t much difference in power, with the mobile GPU coming in at 100W (TGP) and the desktop card being 132W (TBP). Of course, they both come with 8GB of GDDR6 memory over the 128-bit bus and at the same 14Gbps speed.

According to the review from MykonstHowever, the laptop’s GPU can still be overclocked, which could result in steady 2.5GHz clocks. However, memory overclocking does not seem to work, as the card immediately enters safe mode. GPU-Z software confirms that this is a mobile GPU and is fully compatible with AMD drivers:
It appears that these companies are simply reusing boards that would have been used for the RX 6600 desktop models. The RX 6600M laptop has almost the same GPU, almost the same configuration, and even memory. In most cases, this procedure will be as simple as installing a new GPU and flashing the BIOS of the laptop.
Although the cards sold on Chinese websites have full PCIe 4.0 x16 slots, they are of course not plugged into 16 threads. Both desktop and mobile GPUs are limited to 8 lanes.
It goes without saying, but these models are not officially supported by AMD, but since the drivers only check the PCI GPU hardware ID, they will be detected as portable and the drivers should work regardless. These cards are also much cheaper than the desktop models, but they come with a limited warranty and are likely to be subject to additional import duties.
