Conclusion an everyday workhorse for users who dabble in a bit of video encoding and light-load gaming, Ryzen 5 3400G is decent enough.

The Ryzen 5 3400G continues AMD's solid work in offering competent solutions for everyday computing. Applicable to a wide range of budget systems that don't need a full-on discrete graphics card present, this CPU+GPU processor's Zen+ and Vega heritage shines through when compared to rival Intel chips costing about the same as the £140 outlay.

Sure, there are compromises on both fronts, but as an everyday workhorse for users who dabble in a bit of video encoding and light-load gaming, Ryzen 5 3400G is decent enough. £300 or so will buy you this chip, 16GB of memory, a 256GB NVMe SSD, and an inexpensive B450 motherboard. The quartet combines to offer an amenable entry point into the PC space, with the opportunity of upgrading to discrete graphics as and when budget permits.

All that said, it's worth remembering that Ryzen 5 3400G is effectively a last-gen chip dressed up in new branding. In an ideal world we'd like to see the Zen 2 architecture employed on the CPU front and a Navi derivative on the GPU. Taken as it is, the Ryzen 5 3400G, priced at £140, offers reasonable performance through liberal use of older technology.

The Good
The Bad
Decent multi-threaded performance
Better IGP than Intel
Attractive pricing

Doesn't overclock fantastically
Iterative improvements over last gen
No QuickSync type of tech

Would have been nice to get a comparison with the 2400G, to see if there is much to split the two, since the 2400G can be found for slightly less than the 3400G. One thing I have seen is that the new Spire coolers forgo the copper core which the previous generation had, compensating with higher fan speeds and noise.
I have to say that I'm surprised that the gaming “minimum fps” is dropping so low on these parts. The text refers to muted base/boost frequencies, but according to the table, these should be 3.7 and 4.2 respectively which is hardly low. The 8100 is a 3.7ghz peak part, I think, by way of comparison.

I appreciate that gaming was always Zen+'s weak link, but it seems significantly behind the 2600x clocked at 3.6/4.2 albeit that the latter has two extra cores. I'm struggling to account for that, beyond 65w vs 95w, which suggests AMD is making a mistake not offering a 95w part, or else are purposely leaving the G-parts in a lower-performing bracket to protect the more expensive chips.

Or, could this be related to limited throughput for PCI-E graphics cards on the G-parts? I think that was a “thing” for the 2200G/2400G. Does that still apply for the 3400G? It has more PCi-E lanes, but do the motherboards accommodate that?
Not even 720p with low settings yet? I expected more AMD.

Agreed, where is the MAX watt part (~95w-140w?)? Throw more at the gpu please! They are pointless until they can do 1080p for tv at least (that is the point of your shiny new HTPC for many ppl). Poor people PC's are getting better (as usual), but useless to me with essentially useless gaming. A few GB of DDR5 on a layer wouldn't be bad either. El cheapo to get this done and change the gaming massively. Adding 4GB local to these chips is peanuts (heck even 8GB). You'd still have to turn stuff down on many things but at least you'd get some 1080p playable. Just charge a bit more so it won't kill cards, but at least we have options to run without a card and game on an HTPC for a bit until you can afford the gpu, or in my case, one comes out that you WANT (7n NV, get with it! Won't bite until I see these and what NV can do with samsung 7nm).
If you can get the 2400g for £108 vs £140 3400g then the 2400g is the better buy. Considering these, but would prefer the Low power variant 3400ge , but that is not seen around these parts. How many mobo's expsoe the CTDP , so that they can be limited to 45w? all , none , or topend only.
“Doesn't overclock fantastically” What?!
4.1Ghz all cores @1.36 vCore (MB has no LLC and at load it drops to 1.25-1.26) It can be easy get 4.2-4.3.
iGPU 1700 @1.1625 vGFX core. And can easy get more.

Temps 25-30 in idle and 65 in OCCT, Linx, Prime.
