For those who still don't know: Ryzen AI 400 is just a rename of Ryzen AI 300.

Their goodwill for desktop APUs only goes as far as approximately GTX 1050 Ti graphics power.
Quote from: captainobvious on Today at 13:09:31Very true, neither company is interested in selling top iGPU to customers.
Strix Halo' iGPU has access to 256 GB/s memory due to its 256-bit RAM access and its performance is approx on the level of a 4060 Laptop. 256 GB/s equals to quad-channel (4 * 64-bit per RAM channel) in the desktop. In desktop (if we define the word "desktop" as anything that looks like a (big) desktop tower), only the (entry level) Threadripper platform offers quad-channel.
So, there's simply not enough bandwidth.
PS: Panther Lake's Arc B390 iGPU is connected to 128-bit (dual-channel) memory running at LPDDR5X-9600 MT/s, but it has bad 1% FPS lows (YT/Just Josh: ExpertBook Ultra Panther Lake youtu.be/jduWl1J_4lQ?t=630). I wonder what is up with that and if it's caused by the LPDDR5X' high latency when running it at 9600 MT/s. Now I wonder if Strix Halo also has bad 1% FPS lows issue.
