Review: AMD Ryzen 5 3400G APU
Vega11 based desktop APUs from AMD are here, in this review we take the Ryzen 5 3400G for a spin. AMD has been going strong with their processors and APUs. But is it all that it is cooked up to be?

Would require 7nm I/O die and APU as one chip instead of separate CPU and GPU chiplet.
5700 XT has ~460GB/s available bandwidth for 20 WGPs at around 2GHz.
Let's say 8 WGPs at 1.4GHz for power efficiency... that would be around 128GB/s. Could probably be unhindered even at 100GB/s. But having mere 4GB of dedicated HBM would make all bandwidth concerns go away.
I don't think there's space on an AM4 chip for the 8-core CPU die, a large GPU die, AND a HBM die, unless they can do the stacked thing, or something. Isn't dual-channel high-speed DDR4 *fast enough* for APU GPUs nowdays? You can pull close to 60 GB/s on those things, that's pretty dope.

Didn't they propose this years ago but never did anything with it?

I feel like i remember AMD saying they won't utilize the 2nd Zen2 chip area for a GPU at least for Zen 2. I could be wrong though.

That's correct, that's why I wrote that it would not be separate chiplet.

I think that APU with 4C/8T Zen2 and Navi with 8 WGPs would be great entry gaming chip for 1080p. And would win in notebooks. In up to 25W.
High-End APU with 6C/12T Zen2 and Navi with 12 WGPs would just smash 1080p at good details, but it would likely need onboard HBM for iGPU. This would win in up to 45~65W notebooks just due to size.
Apparently, on desktops, higher grade APUs will have to wait for DDR5 even while Navi made improvements in GPU performance vs. required memory bandwidth.
And AMD is about to improve that. Then their I/O die becomes fully enabled chipset. Form Factor will shift.
Funny thing is that it reminds me of Raja Koduri, who after joining intel stated that AMD does not have eco system, software, roadmap, ...
