    Re: AMD Ryzen 5 3400G

    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.

    Re: AMD Ryzen 5 3400G

    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?

    Re: AMD Ryzen 5 3400G

    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).

    Re: AMD Ryzen 5 3400G

    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.

    I mean, I play 1080p on my A10-7870k which is significantly worse than the 3400G...

    I couldn't drop the power rating of my 2200G but that was in an X470-PRO board. Perhaps that isn't something ASUS were expecting as a combination, but I don't have a uATX board to try the APU on.

    Quite, my daughter played stuff like Minecraft quite happily on an old A10 APU. There are plenty of use cases beyond the latest AAA games.

    What a pointless review. Who in their right mind would not run 3466 ram on an APU, ~irrespective of mobo vintage or model? No 2400G comparison?

    Yes, it would be nice to have the 2400g comparison, but the 3466 ram is an expense some buyers would go to in order to get maximum performance as 3200 kits dont cost all that much more than a 2666 kit, Definately not an amount that could be spent on a dedicated gpu

    RAM speed translates pretty much directly into frame rate in AMD's APUs; memory bandwidth is the limiting factor on GPU performance. (Replacing DDR-2400 with DDR-3200 is likely to improve your gaming frame rate by 20% or more.) You get a lot of benefit from higher speed RAM even if it has higher latency numbers; the higher latency affects CPU performance but not GPU performance. So a kit of (say) DDR4-3200 that is really the same speed for random access as DDR4-2400 or 2666 but with higher clock rates for bulk transfers is worth buying and doesn't cost much extra; I'd expect to pay an extra $10-20 for 16GB.

    You can get even more benefit, mostly for compute performance, with RAM that combines high speed and low latency. But that RAM sells at a large premium, you might pay as much as double the cost of slower RAM. It is unlikely to be worth buying; use that money for a different system upgrade instead.

    Their sample didn't overclock nearly as well. There were only able to get 3.95 GHz.

    Re: AMD Ryzen 5 3400G

    Thank you Hexus you cheered me up today

    "Rather than employ the latest-and-greatest "" Zen 2 architecture, the CPU portion uses Zen+, so in line with a Ryzen 5 2600, for example. "(text removed)

    "As on 2400G, AMD uses a single, fully-populated CCX that offers four cores, eight threads and 4MB of L3 cache. It also keeps the dual-channel DDR4-2933 memory controller of its direct predecessor, which all makes sense. The graphics portion is also familiar, as 3400G houses the same Radeon RX Vega 11 GPU, albeit clocked in at up to 1,400MHz instead of a peak 1,250MHz."

    I have a 2400G sitting in a box and am ready to do a build for it, partly for the hobby aspect and partly because I need a living room setup that's not a second hand laptop with a dodgy screen and mouse pad. Now I know that
    -it's the same core process tech as the new 3400g chip
    -it has the same graphics with a mild OC (overclock).
    -it costs £140 roughly and I paid £138.87 for my 2400G in early February 2019
    -I can make use of the spare motherboardS I bought
    -I can make use of the Samsung B die memory I also bought second hand (assuming the stuff works, didn't like my desktop much) from the ebay
    -I am still keeping up to date with technology fashionista trend

    Re: AMD Ryzen 5 3400G

    It's not the same core process tech. The 3400G uses 12nm from GlobalFoundries, rather than the 14nm process used for the 2400G. The chip is not smaller; the layout is the same, just the transistors are a bit smaller. The process update allows AMD to squeeze a bit of extra speed out of the design. The 3400G also comes with the more powerful Wraith Spire cooler rather than the Wraith Stealth that is packaged with the 2400G.

    All of that adds up to a 100 MHz bump in base clock, a 300 MHz bump in turbo clock, and a 150 MHz bump in graphics clock. The official RAM clock ceiling stays at 2933 MHz, but people have had more success overclocking the RAM speed of the 3400G; you have much better odds of being able to hit 3200 MHz.

    Those are all useful improvements. But they don't make your 2400G useless, and it might even be worth buying one now if the price is right. For example, here in the US Micro Center is currently offering the following prices on AMD APUs:

    2200G: $60
    3200G: $90
    2400G: $90 (including $30 discount if you also buy a motherboard -- you need one, right?)
    3400G: $130

    At those prices, the 2400G is a useful $40 cheaper than the 3400G. It's hard to make a case for the 3200G, since the 2400G at the same price will usually outperform it at standard clocks. (The 3200G may have more overclock headroom and it achieves a slightly higher single core speed. But its lack of SMT means it is left in the dust when more then four cores are in use. It also has 3 fewer graphics cores, a substantial disadvantage in graphics performance.)

    Eventually AMD and its dealers will sell out of the last-generation APUs and that option will no longer be available. But for now the 2400G appears to be a reasonable purchase for a budget-minded builder.
