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?

I did think the gpu in the apu access the ram with anything else than the normal ram controller, and the infinity fabric.
Do they have a pciex path in the middle?
Looking forward to Zen2-based APUs--although I'm not going to be interested, personally. But the irony is that an iGPU should theoretically see big gains in performance directly related to PCIe4--probably the best case for PCIe4 on a graphics bus, I should think. It doesn't mean much for discrete GPUs, of course, since they are already much faster running from their local Vram bus than the PCIe4 system-ram graphics bus. But there is the rub! These APUs are entry-level products--so motherboard PCIe4 circuitry might hurt that market by elevating the price of the required motherboards. Have to wait until PCIe4 becomes commonplace, I suppose.

The GPU is still functionally a PCIe device, and has lanes dedicated to it. So I guess the CPU and/or mem controller is linked to it via PCIe internally. The higher potential DDR4 speeds of Zen 2 should provide a more meaningful uplift.

Also, the bigger cache of Zen2 should help

I'm kind of imagining a Zen 5 APU with low mid-range ray-tracing graphics performance.
