AMD's latest GPU architecture, RDNA 2, has impressed the desktop, so it seems logical to target laptops as well. And, yes, that's exactly what AMD has just announced. The red team has broken the cover to launch three new GPUs for the laptop market: the Radeon RX 6800M, RX 6700M and RX 6600M. Could we finally see some competition in the laptop graphics space?
Gaming laptops have experienced significant growth over the past year, 27% more than the previous year, according to AMD. This is awesome. The vast majority of these gaming laptops have used Nvidia silicon to provide the muscle needed to handle the latest games. This is something AMD doesn’t want to be repeated this year and its RDNA 2 graphics architecture means it really has a good chance to change.
Compared to the first generation of RDNA, this last turn offers 1.5 times the performance or consumes up to 43% less power. It is also capable of having a 1.77X better performance when the laptop is not plugged into the socket. This is a promising start, for sure.

The top of the new mobile line is the AMD Radeon RX 6800M (Navi 22), which features 40 computing units and lightning accelerators, a 2,300MHz game clock, 12GB of GDDR6 and 96MB of Infinity Cache.
These new graphics chips also support smart access memory (AMD’s impressive printing in Resizable BAR) and AMD SmartShift, which can change the focus from CPU to GPU (or vice versa) when needed. Basically on laptops with AMD CPUs and GPUs, you can expect better overall performance, and with an increase of about 10%, that’s no small feat.
The big question for any GPU is how does it work in games? Pretty good, according to AMD's own figures, at least. Obviously, we should check them, but as long as they are close to the numbers presented by AMD, it gives a good image for AMD's new GPU.
AMD showed another slide during the pre-briefing comparing the 12GB RX 6800M between the 8GB RTX 3070 and the 8GB RTX 3080, and was competitive as Assassin's Creed Valhalla, Borderlands 3, CoD: Black Ops Cold War, Dirt 5 and Resident Evil Village. While it’s worth noting that all of these, Call of Duty bar, are games developed with AMD, so they’ve been optimized for their hardware to some extent. This should not detract from the decent performance offered.
The Radeon RX 6700M (Navi 22) is a stepped from the top chip of the lineup and features 36 CU, 10GB of GDDR6, 80MB of infinite cache, although it has the same 2,300MHz game clock. It is still aimed at 1440p gaming, with AMD at 100 fps in popular gaming. It should be a cheaper GPU for laptop manufacturers.
Finally, we have the AMD Radeon RX 6600M (Navi 23) focused on 1080p gaming. It claims 28 CU, with a 2,177 MHz game clock, 8 GB of GDDR6 and 32 MB of Inifinity cache.
Once again, AMD is aiming for 100 fps in a wide range of titles; the more demanding triple A titles will be below, while some of the fastest sports names will handle more than 200 fps. 1080p is a perfectly fine resolution for moving games and it will be interesting to see how it compares to the GeForce RTX 3060.
AMD also introduces a design framework for manufacturers that aims to increase performance, help combine hardware with the right screens, make sure everything works well with AMD Radeon software, and that the end user has essentially a good overall gaming experience. .
A big challenge for AMD is convincing laptop makers to use their graphics silicon instead of Nvidia, but it looks like it has already made inroads here, with Asus, HP, MSI and Lenovo to produce laptops around the Radeon RX 6000M GPUs. The first will be available in early June: the Asus ROG Strix G15 will be the flagship machine, which will feature a Ryzen 9 5900HX and a Radeon RX 6800M.
