Its a shame it still has vega gpu just tad overclocked.

Would be really interesting to have titles relevant for the iGPU tested here - like Counterstrike Global Offensive, League of Legends, Dota2, Fortnite and Apex Legends. Since building a cheap system to participate in the popular games that are free, or for entry level esports gaming, this CPU/APU could be very interesting.
I know the previous 2400G provided very playable framerates in these titles, but it'd be interesting to see how performance there increased. More so than in older single player games that very few people will play today compared to the popular esports titles.

Also would be nice to know how those run for low end gaming like mame and ps2 wii wiiU emulators.

Well yeah but...even non gaming site reporting is very gaming centric.
~If it doesnt game at 1080p at 60fps, it is beneath contempt.
Yet I struggle to think of a run of the mill; ~office, class, non gaming home app/work load - where a; big; ugly hot noisy separate ecosystem discrete gpu would be anything but an; expensive, power hungry, time wasting pain.
If time is of the essence, as it is in high labor cost economies, if the 3400g is a tad over priced - in this context it is a bit ..+~$40? - meh.
The apuS seem to sell steadily, even in DIY, despite the press they get. On the mindfactory charts they would represent one of Intel's best sellers if they were in the other column.
I dont recall it being clear that the 32/3400g are also a cpu shift from 14nm++ to 12nm - whatever the significance of that is?

A natty further APU economy for the budget challenged, is that the significant cost of a PSU can effectively be avoided.
As the power draw is so low, & there is no need for a gpu power connector, then almost any old discarded 300W+ PSU would suffice afaict.

No real reason to upgrade from a 2200G/2400G. At least for me, there isn't.
However, I updated the motherboard's BIOS.

You describe these as binned 2200/2400G parts, but I'm pretty sure the APUs being a Gen behind makes them Zen 1 cores, while Ryzen 3000 APUs are Zen+ cores.

32/3400 are indeed on 12nm node, which is s step down from the first 1xxx series Ryzens which were on 14nm node. The practical significance of a smaller node is usually lower power consumption which in turn allows for higher clock and performance (in this case also higher iGPU clock). On manufacturing side it provides better yields and lower costs (once the process is mature enough).
Anyway, my gripe with these procs is the misleading naming. With 3400G you basically get a 2xxx series 4C/8T with Vega 11 slapped on, when based on the name you'd expect a 3xxx series proc. Same with the 22/2400G which have 1xxx series procs.
Other than that, still very good entry-level CPUs, with a good upgrade path.

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.

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?
blkspade
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.

I was mostly curious about the igpu and ram overclock potential seeing as the graphics is by far the limiting factor of these chips. Currently I have my 2400g underclocked and undervolted to 3.4ghz with the memory and igpu overclocked and GPU is still the limiter of the system.

I really dislike how AMD messes up the generation numbers with Ryzen APUs. A typical consumer could buy this chip thinking that it's like any other 3000-series CPU when it's actually a binned last-gen product. Having to wait until next year for a Zen 2 APU (with Navi) is also not ideal - you'd think a chiplet design would allow more flexibility here.
icedman
hey hilbert i noticed these run at 1400mhz on the igpu does that mean these don't have that dead zone between 1350 and 1450 that the 2200g and 2400g had. mine is stuck at either 1300mhz or i have to go up to 1500mhz nothing in between works on mine not that its a big deal it works well at 1500mhz.
BLEH!
Waiting for the ACTUAL Zen-2 APUs with 8 cores and a decent IGP stuck on there.

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, ...
BLEH!
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.
Fox2232
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.
